After dehydration effects: The request could not be satisfied


How Dehydration Affects the Body

As you bask in the glory of summer, it’s crucial that you keep yourself hydrated. With heat waves reaching record-breaking heights throughout the country, medical experts are stressing the hidden dangers of dehydration and its effects on both the mind and body, now more than ever. In fact, new studies have shown that dehydration can critically impair a person’s cognitive performance in as little as two hours—affecting the ability to focus, perform executive functions, and control motor coordination. To better understand dehydration and the impact it has on the body, let’s explore the causes and symptoms, and review preventative measures that you can take to beat the summer heat. 

What is Dehydration?

In technical terms, dehydration is the result of excessive body water loss. This typically occurs when an individual loses more than two percent of their bodily fluids. While the body naturally loses fluid throughout the day—via perspiration, bowel movements, urination, and various other day-to-day happenings—if it is not replenished, dehydration can quickly set in. This ailment can restrict, and can even prohibit, the body’s ability to carry out its necessary functions, potentially leading to serious health issues. 


Dehydration can occur for a number of reasons, and most people will experience its milder symptoms at some point in their lives: extreme thirst, headaches, fatigue, and dizziness. Some popular causes of dehydration include:

  • Excessive sweating – Sweat is the body’s natural cooling mechanism, releasing fluids to maintain body temperature. Prolonged exposure to heat and vigorous exercise increase the amount you sweat, thus increasing the amount of fluid you lose. 
  • Certain medications – Diuretics, antihistamines, blood pressure medications, and antipsychotics can increase the risk of dehydration, as they encourage frequent urination. 
  • Vomiting or diarrhea – This is the most common cause for dehydration, causing a tremendous loss of water and electrolytes in a short amount of time. 

Risk Factors

Dehydration can affect anyone, but there are certain demographics that are at greater risk. Young children, the physically disabled, and the elderly, for example, often rely on caretakers to provide water. Therefore, in some cases, their need for hydration may go unnoticed for a longer period of time than it would for an able-bodied adult or older child who can recognize their thirst and act on it. Others at greater risk for dehydration include:

  • People with chronic illnesses – If you have diabetes, chronic kidney disease (CKD), Alzheimer’s, or other pre-existing health condition, you are at a higher risk of dehydration.  
  • Athletes – Whether you are a professional athlete or just someone who enjoys exercising outside, it’s vital that you stay hydrated. In warm, humid months, this becomes even more important, as exercising in this weather can increase your body temperature and the need for more fluids. 

How Does Dehydration Affect the Body & Mind?

You’ve heard it before, and you’ll hear it again: About 60 percent of the human body is made of water—making hydration essential for regulating bodily functions. Water is used to perform a multitude of specialized operations for the body: protecting organs, flushing out waste and toxins, and carrying nutrients and oxygen to the cells. Thus, limiting the amount of water your body has access to can critically affect its ability to perform these functions, reducing your internal sodium and electrolyte levels, and causing physical and cognitive impairments. This can lead to difficulty performing tasks that require attention, motor coordination, and executive function—grammatical reasoning, mental math, decision making etc. This is why it’s vital that you monitor your daily fluid intake and watch for symptoms relating to dehydration. 

What Are the Symptoms of Dehydration? 

Most mild cases of dehydration are characterized by thirst; however, this isn’t always a reliable indicator. In fact, most people don’t feel thirsty until they are already dehydrated. Spooky, right? That’s why it’s imperative that you increase your water intake throughout the day, even more so when you’re ill or spending time outside on a sweltering summer’s day. That being said, most signs and symptoms of dehydration can vary greatly depending on a person’s age, health, and body. 

Infants & Toddlers 

Dehydration in small children and infants can be difficult to recognize, as they aren’t always able to effectively communicate their discomfort. Signs of dehydration in children often include, but are not limited to:

  • Sunken eyes and cheeks
  • Dry mouth and tongue
  • No wet diapers for three or more hours
  • Irritability


To determine whether you are experiencing dehydration as an adult, look for the following symptoms:

  • Extreme thirst
  • Dark-colored urine
  • Dizziness
  • Fatigue
  • Headaches
  • Confusion
  • Less frequent urination
  • Nausea 

When to Seek Medical Treatment

While most occurrences of dehydration can be reversed by simply increasing fluid intake, severe cases of dehydration may require immediate medical attention. To pinpoint the degree of dehydration, your doctor may order a blood test and urinalysis. Nevertheless, the only truly effective way to treat dehydration is to replace lost fluids and electrolytes. Emergency rooms (ERs) often deliver this intravenously (through the vein) for maximum body absorption and speedy recovery. 

Serious Complications

If not addressed, serious cases of dehydration can severely complicate the body’s and mind’s ability to perform. In some cases, this can lead to hallucinations and organ shutdown. Other complications caused by untreated dehydration can include:

  • Urinary and kidney problems
  • Seizures, or involuntary muscle contractions 
  • Loss of consciousness
  • Heat injury, mild heat cramps, heat exhaustion, and heatstroke
  • Hypovolemic shock, or low blood volume shock caused by a drop in blood pressure and oxygen

Tips for Preventing Dehydration This Summer

The best way to treat dehydration is to stay hydrated. This doesn’t mean you need to chug a gallon of water every hour. Medical experts advise you to drink about two liters, or half a gallon, of filtered water every day. This is a general guideline, and depending on your circumstances, you may require more or less water. Here are some other tips to help you stay hydrated this summer:

  • Hydrate before, during, and after exercising.
  • Monitor your hydration based on your level of thirst and the color of your urine; darker urine could indicate dehydration.
  • Always carry a reusable water bottle and take frequent sips from it throughout the day. 
  • Eat a well-balanced diet of grains, greens, protein, fruits, and veggies.

How Long Does It Take for Your Body to Rehydrate
– Hydrant

According to a recent study from the Journal of Strength and Conditioning Research, your body can alleviate mild dehydration in 45 minutes with 20.3 oz (600ml) of water.

The time it takes for your body to rehydrate mainly depends on how dehydrated you are. In this article, we take an in-depth look. 



The time it takes for you body to rehydrate depends on how dehydrated you are

If you are severely dehydrated, it’s likely that you will be hospitalized and put on intravenous hydration for up to 24 hours to rehydrate your body, or until you’re able to drink oral rehydration fluids yourself. [1] When you’re severely dehydrated, you need to put back a LOT of fluid, and it needs to be balanced with the nutrients that your body usually contains.

If you were to suddenly put a lot of water back into your body after being severely dehydrated, it might cause your body to go into a form of shock, so you need to pace yourself[2]

At less severe dehydration levels that are still serious, it’s possible that you’ll only be drinking oral rehydration fluids. CDC guidelines for those suffering from dehydration through Cholera recommend drinking up to 1 liter of ORS fluid per hour for an adult, and children 20ml / kg of body weight. [3] Want to learn the fastest way to rehydrate? Read about it here.



Dehydration Symptoms: How to tell if you’re dehydrated

You are dehydrated when you lose more fluids from your body than are taken in, for example, when you have stomach flu mixed with diarrhea or if you consume alcohol. Dehydration can keep the body from functioning normally, and as a result, you may experience symptoms of dehydration. Symptoms of dehydration include:

– Dry mouth

– Dry skin

– Light-headedness

– Urinating less frequently 

– Fatigue

– Sluggishness

– Muscle cramps

– Changes in blood pressure

– Changes in heart rate

– Changes in body temperature

There are different levels of dehydration: mild, moderate and severe dehydration and many more signs that indicate you are dehydrated. If you are experiencing severe symptoms, we recommend seeking medical care immediately.



Is your routine dehydrating? 

Are you concerned about your own hydration levels? Take the quiz below to find the best Hydrant for your hydration routine.



How long does dehydration last? 

If you don’t treat dehydration by drinking water and in some cases taking on electrolytes in the right quantities, your dehydration may last indefinitely.   

If it progresses for long enough, you can die from dehydration. Most of us know this – you can go weeks without food, but only days without water. New York Times has reported results of a study that showed that 75% of Americans were chronically dehydrated. 

This meant that they were not meeting their daily requirement for water intake, and were staying in a dehydrated state for long periods of time! In that scenario, recovering from dehydration requires a complete overhaul to your routine, to ensure you’re making it a daily habit to consume enough water.



So what is Hydrant? 

We made Hydrant to be an effective way to rehydrate your body quickly, based on World Health Organization guidelines for oral rehydration solutions. ORS can have up to 3x the electrolytes of traditional carb-based sports drinks and contains only 6 grams of sugar. 

Drinking enough water each day can be hard for any number of reasons and using Hydrant makes hydration easier. Our oral rehydration solution contains electrolytes, sodium, potassium, magnesium, and zinc that mimic your body’s natural electrolyte makeup. When you lose water from your body, most of the time you also lose electrolytes. If you just replace the water, but not the electrolytes, you further imbalance your body.  To perform at your best throughout the day, it’s best to quickly replenish your body, using a solution that mirrors your biological electrolyte and water balances.

 It’s easy to fit into your routine, and many of our customers start their day with a Hydrant to make sure they are at their baseline hydration level from the get-go. Because it’s in a convenient powder pack, wherever you need quick recovery from dehydration, you can mix it with water and get hydrated fast.

Dehydration | Cancer.Net

Dehydration happens when a person does not take in enough fluid or loses too much fluid. Your cells and organs depend on water. Without it, the human body cannot function properly. The water in your body performs many tasks:

  • Transports nutrients and oxygen

  • Controls heart rate and blood pressure

  • Regulates body temperature

  • Lubricates joints

  • Protects organs and tissue, including the eyes, ears, and heart

  • Creates saliva

  • Removes waste and toxins

If you are receiving cancer treatment, you may be at a higher risk for dehydration due to side effects, such as diarrhea and vomiting.

What are the signs and symptoms of dehydration?

The longer you go without taking in enough fluid, the more dehydrated you will become. Thirst is one way your body alerts you to drink more fluid. However, sometimes you can become dehydrated without feeling thirsty. Other possible dehydration symptoms include:

  • A dry or sticky mouth or a swollen tongue

  • Fatigue or weakness

  • Irritability

  • Dizziness or lightheadedness

  • Nausea and vomiting

  • Headaches

  • Constipation

  • Dry skin

  • Weight loss

  • Dark yellow urine or a decrease in urination

Severe dehydration can be life-threatening and needs immediate medical treatment. It can cause the following symptoms:

  • Extreme thirst

  • Low blood pressure

  • Fever

  • Rapid heartbeat

  • Lack of urination for more than 8 hours

  • Sunken eyes

  • Inability to sweat

  • Inability to produce tears

  • Disorientation or confusion

Talk with your health care team about any new symptoms or change in symptoms that you experience.

What are the causes of dehydration?

You lose water every day through natural body functions. These include breathing, sweating, and going to the bathroom. Most people easily replace that fluid through drinking and eating. But certain conditions affect the body’s ability to stay hydrated. These include:

  • Diarrhea, nausea, and vomiting. Cancer treatment, including certain types of chemotherapy, radiation therapy, and surgery, can cause these side effects.

  • Fever. A high fever can cause dehydration. People receiving cancer treatment may be at risk for developing infections that can cause fever.

  • Age. Infants, children, and older adults are at a greater risk for dehydration. Young children pass water and electrolytes out of the body frequently. Electrolytes are minerals that help regulate the body. As a person gets older, the body slowly loses the ability to conserve water. Older adults also are less likely to sense that they are thirsty. They may not eat or drink enough, especially if they live alone.

  • Chronic illness. Many diseases — such as diabetes, cystic fibrosis, and kidney disease — increase dehydration risk and the need for fluids. For example, people with uncontrolled diabetes urinate frequently. Some medications can also cause a person to urinate or sweat more than normal.

  • Environment. Living, working, and exercising in a hot or humid environment increase the need for fluids. People living at high altitudes, from 8,000 feet (2,400 meters) to 12,000 feet (3,700 meters) above sea level, also need more fluids. This is because their bodies lose water as they work to take in more oxygen.

  • Exercise. Everyone loses water through sweat. Exercise can make you sweat more. Even if you do not see sweat, you are likely sweating. The more you exercise, the more fluid you need to replace.

How is dehydration diagnosed?

Your doctor can diagnose dehydration using several methods:

  • Taking your vital signs, such as your blood pressure and pulse

  • Testing your blood for factors such as your electrolytes and kidney function

  • Testing your urine for the level of dehydration or to find out what may be causing dehydration

How is dehydration treated?

Relieving side effects, also called palliative care or supportive care, is an important part of cancer care and treatment. Treatment for dehydration depends on its severity. For mild dehydration, you might try the following:

  • If you are able to drink, take in small amounts of fluid frequently instead of a large amount at one time. Drinking too much at once may cause vomiting.

  • Keep a water bottle with you at all times, and sip from it throughout the day.

  • Drink a large glass of water before bed and when you wake up each morning.

  • Suck on ice chips or popsicles if you have trouble drinking or eating.

  • Apply moisturizer to cracked lips and medication to mouth sores. This can make drinking and eating less painful.

  • If you have diarrhea, choose drinks that have sodium and potassium to help replace these lost minerals.

  • Keep ice and drinks within reach so you do not have to get up as often, if you are tired.

You doctor may recommend an oral rehydration solution if you are not vomiting or experiencing diarrhea. In this case, you may be moderately dehydrated.

Your doctor may prescribe fluids to given directly through a vein, also called intravenous (IV) fluids. In this case, you may be severely dehydrated.

How can dehydration be prevented?

The following tips can help keep your body’s fluid balance in check:

Drink lots of fluids. The amount of fluid needed each day to stay hydrated depends on your health, treatment, and lifestyle. Ask your doctor how much water you should drink. If you dislike plain water, try drinking flavored water or adding a slice of lemon. Other fluids can also help, including milk, low-sugar juice, and caffeine-free tea.

Remember to avoid foods and drinks that may contribute to dehydration. Avoid alcohol. Choose drinks with low sugar and low or no caffeine. Water is often a better choice than fruit juice, soda, or coffee.

Eat foods with high water content. Drinking water is the best way to hydrate. But many foods contain water and can also help replenish lost fluids. Choose foods such as lettuce (95% water), watermelon (92% water), and broccoli (91% water). Soup, popsicles, and yogurt also have high water content.

Manage side effects. Cancer treatment can cause nausea, vomiting, or diarrhea. Talk with your health care team about ways to prevent or reduce these side effects and any concerns you have about dehydration.

Monitor your environment and activity. Do not wait to drink water or other fluids. Make a conscious effort to drink regularly. Drink more often before you exercise and before you go outside in hot weather. During an illness or if you are feeling unwell, be proactive and drink water to stay hydrated in order to help your recovery.

Dehydration – Managing Side Effects

What Is Dehydration:

Dehydration is an excessive loss of body fluids. It occurs when the output
of fluid exceeds fluid intake.

  • Side effects of treatment such as vomiting or diarrhea can lead to chemotherapy
  • Infections, high fever, bleeding, or even something as simple as not drinking enough
    fluids can also lead to dehydration.
  • The danger of dehydration is greatest for a person living alone, as he/she may not
    recognize the signs and effects of dehydration.
  • Chemotherapy Dehydration is a dangerous symptom, one that can be life threatening
    if the signs are not recognized and treated. When a person suffers
    from dehydrated, he may need to seek medical help to receive intravenous fluids.
    A person can live for a long time without eating, but can function only a short
    time without fluids.
  • Electrolytes, such as potassium and sodium, are always present in the blood.
    When these electrolytes are too high or too low, they can cause problems.
    Some can be life-threatening. Confusion and disorientation are symptoms of
    dehydration resulting from an electrolyte imbalance. Thus, a person who
    is having severe vomiting or diarrhea should not be left alone to care for him or
    herself. When a person suffers from dehydration, it is difficult to judge how well
    he/she is doing and whether or not he/she needs help because of this confusion.

Dehydration Symptoms:

  • Dry mucous membranes (dry mouth)
  • Your skin may appear loose and crinkled and could keep standing up in a tent when
    lightly pinched and pulled up.
  • Secretions may become thick and dry.
  • Little or no urine output.

How to Manage the Effects of Dehydration:

  • The best way to treat chemotherapy dehydration is to prevent it.
    Recognize early symptoms of dehydration such as thirst and dry mouth and take steps
    to rehydrate yourself.
  • Try to estimate how much fluid is lost and how much is taken in. It is not
    easy to tell how much fluid a person is losing unless it is being measured.
    Keeping a count of how many times a person is having diarrhea or vomiting may be
    easier than actually measuring the amount, and this information will be very helpful
    when talking to the doctor about chemotherapy dehydration symptoms. It is
    also important to keep track of how much fluid is taken in.
  • Increase fluid intake. If fluids cannot be kept down, sometimes
    taking small pieces of ice works better, but it takes a lot of ice to get enough
    fluid. Taking small sips frequently is better tolerated than drinking large
    amounts. Fluids such as water, soda, bouillon, juice, or whatever is tolerated
    can be tried. Alcohol and caffeine should be avoided because they increase
    the effects of dehydration.
  • Minimize or eliminate fluid loss when signs of dehydration are present.
    The first step is to stop the diarrhea or vomiting and to continue drinking fluids
    to replace those lost. Stopping diarrhea or vomiting usually requires medication.
    If pills are vomited, rectal suppositories are available. In some cases of
    chemotherapy dehydration, an injection may be needed.


  • If you are vomiting, stop eating. Once you stop vomiting, start back on food
    slowly. Start with small amounts of clear liquids, such as broth, juice soda,
    sports drinks, or water. Then, advance to light, mild foods like jello,
    bananas, rice, or toast. Soon, you will be back to solid foods.
  • Avoid caffeine and smoking when symptoms of dehydration are present.
  • Suck on hard candy, popsicles, or ice if you are susceptible to chemotherapy dehydration.
  • Take the medications for nausea and vomiting as prescribed by your doctor.
    If you are running low, ask for a refill.
  • Notify your nurse or doctor if you feel nauseated during chemotherapy.



  • Drink plenty of clear fluids (8-10 glasses per day) to fight off the effects of
    chemotherapy dehydration. Examples: Gatorade, broth, jello, water, etc.
  • Eat small amounts of soft bland low fiber foods frequently. Examples: banana,
    rice, noodles, white bread, skinned chicken, turkey or mild white fish.
  • Avoid foods such as:
    • Greasy, fatty, or fried foods.
    • Raw vegetables or fruits.
    • Strong spices.
    • Whole grains breads and cereals, nuts, and popcorn.
    • Gas forming foods & beverages (beans, cabbage, carbonated beverages).
    • Lactose-containing products, supplements, or alcohol.
    • Limit foods and beverages with caffeine and beverages extremely hot or cold.

Medication (available over-the-counter – please read label to make
sure you can take this medication):

  • Loperamide (Imodium®)
  • Kaopectate II®caplets
  • Maalox Anti-Diarrheal Caplets®
  • Pepto Diarrhea Control® (follow instructions on
  • Avoid: herbal supplements (milk thistle, cayenne, ginseng, saw
    palmetto, and others).

Skin Care:

  • Clean skin around anus gently with warm water and soft cloth then dry gently and
  • May apply a barrier cream (such as Desitin®) to
    irritated skin.
  • Allow the irritated skin to be exposed to open air as much as possible.

Medications That May Be Prescribed by Your Health Care Provider:

Vomiting: If the chemotherapy you are taking is
likely to cause or has caused nausea and vomiting, your doctor may prescribe one
or more of the following common anti-nausea medications:

  • Dolasetron (Anzemet®)
  • Granisetron (Kytril®)
  • Ondansetron (Zofran®)
  • Proclorperazine (Compazine®)
  • Promethazine (Anergan®),Phenergan®)
  • Lorazepam (Ativan®)
  • Metoclopramide (Reglan®)
  • Dexamethasone (Decadron®)
  • Famotidine (Pepcid®)
  • Ranitidine (Zantac®)

These can be prescribed for you to take before, during, and/or after chemotherapy.
As you can see, there are many different medications that your doctor can prescribe
to control these symptoms that could lead to chemotherapy dehydration. It
may take trying a couple different medications before finding the right match for

Diarrhea: Your health care provider may recommend
some of the available over-the-counter medications. If these medications are
unsuccessful against your symptoms of dehydration, there are possible prescriptions
that may be recommended:

  • Diphenoxylate – atropine sulfate (Lomotil®)
  • Tincture of Opium
  • Depending on the degree if dehydration, your doctor may recommend intravenous (IV)
    fluids. Sometimes this may be done as an outpatient. In severe cases,
    hospitalization could be required.

When to Contact Your Doctor or Health Care Provider:

Nausea and vomiting:

Note: nausea and vomiting can also be caused by medical conditions
unrelated to chemotherapy. Therefore, it is important to call your doctor if:

  • You continue to suffer from nausea and vomiting despite taking your anti-nausea
  • Nausea that interferes with your ability to eat.
  • Vomiting 4-5 times in a 24 hour period.
  • Feel bloated.
  • Have pain or a swollen stomach before nausea and vomiting occurs.
  • If you are bothered by side effects from the anti-nausea medications.


  • Temperature greater than 100.5 F (38 C).
  • Moderate to severe abdominal cramping/pain/straining/bloating.
  • Black or blood in stools.
  • If dietary measures and medication do not decrease the diarrhea.

Signs of chemotherapy dehydration:

  • Dizziness.
  • Dark (concentrated) urine.
  • Dry mouth and skin.

Your doctor should be notified immediately if you experience:

  • Sudden rapid or irregular heart beat.
  • Confusion.
  • Blue lips
  • Rapid breathing
  • Excessive sleepiness with difficulty arousing.

Note: We strongly encourage you to talk with your health care professional
about your specific medical condition and treatments. The information contained

Dehydration and Heat Stroke | Johns Hopkins Medicine

The danger of dehydration and heat stroke

Dehydration and heat stroke are two very common heat-related diseases that can be life-threatening if left untreated.

What is dehydration?

Dehydration can be a serious heat-related disease. It is also a dangerous side effect of diarrhea, vomiting, and fever. Children and people over the age of 60 are particularly susceptible to dehydration.

What causes dehydration?

Under normal conditions, we all lose body water daily through sweat, tears, breathing, urine, and stool. In a healthy person, this water is replaced by drinking fluids and eating foods that contain water. When a person becomes so sick with fever, diarrhea, or vomiting, dehydration happens. It also happens if an individual is overexposed to the sun and not drinking enough water. This is caused when the body loses water content and essential body salts, such as sodium and potassium.

Occasionally, dehydration can be caused by medicines, such as diuretics. These deplete body fluids and electrolytes. Whatever the cause, dehydration should be treated as soon as possible.

What are the symptoms of dehydration?

The following are the most common symptoms of dehydration. However, each individual may experience symptoms differently. Symptoms may include:

In children, additional symptoms may include:

  • Dry mouth and tongue

  • No tears when crying

  • No wet diapers for several hours

  • Sunken abdomen, eyes, or cheeks

  • Listlessness

  • Irritability

  • Skin that does not flatten when pinched and released

The symptoms of dehydration may resemble other medical conditions or problems. Always talk with your healthcare provider for a diagnosis.

Treatment for dehydration

If caught early, dehydration can often be treated at home under a healthcare provider’s guidance. In children, directions for giving food and fluids will differ according to the cause of the dehydration, so it is important to talk with your child’s healthcare provider.

In cases of mild dehydration, simple rehydration is recommended by drinking fluids. Many sports drinks on the market effectively restore body fluids, electrolytes, and salt balance.

For moderate dehydration, intravenous (IV) fluids may be needed. If caught early enough, simple rehydration may be effective. Cases of serious dehydration should be treated as a medical emergency, and hospitalization, along with intravenous fluids, is necessary. Immediate action should be taken.

How can dehydration be prevented?

Take precautionary measures to avoid the harmful effects of dehydration, including the following:

  • Drink plenty of fluids, especially when working or playing in the sun.

  • Make sure you are taking in more fluid than you are losing.

  • Try to schedule physical outdoor activities for the cooler parts of the day.

  • Drink appropriate sports drinks to help maintain electrolyte balance.

  • For infants and young children, solutions such as Pedialyte will help maintain electrolyte balance during illness or heat exposure. Do not try to make fluid and salt solutions at home for children.

What is heat stroke?

Heat stroke is the most severe form of heat illness and is a life-threatening emergency. It is the result of long, extreme exposure to the sun. In this case, a person does not sweat enough to lower body temperature. The elderly, infants, persons who work outdoors, people with mental illness, obesity, poor circulation, and those on certain types of medicines or drinking alcohol are most susceptible to heat stroke. It is a condition that develops rapidly and needs immediate medical treatment.

What causes heat stroke?

Our bodies make a tremendous amount of internal heat and we normally cool ourselves by sweating and radiating heat through the skin. However, in certain circumstances, such as extreme heat, high humidity, or vigorous activity in the hot sun, this cooling system may begin to fail. This allows heat to build up to dangerous levels.

If a person becomes dehydrated and cannot sweat enough to cool his or her body, his or her internal temperature may rise to dangerously high levels. This causes heat stroke.

What are the symptoms of heat stroke?

The following are the most common symptoms of heat stroke. However, each individual may experience symptoms differently. Symptoms may include:

  • Headache

  • Dizziness

  • Disorientation, agitation, or confusion

  • Sluggishness or fatigue

  • Seizure

  • Hot, dry skin that is flushed but not sweaty

  • A high body temperature

  • Loss of consciousness

  • Rapid heartbeat

  • Hallucinations

The symptoms of a heat stroke may resemble other medical conditions or problems. Always talk with your healthcare provider for a diagnosis.

Don’t Ignore Chronic Dehydration – Novomed Centers

What is chronic dehydration?
Water makes up 60% of our bodies, 85% of our blood, 75% of our brains and even 25% of our bones. Chronic dehydration affects an incredible two out of three people simply because most of us aren’t drinking enough liquid – especially water.

The amount you need to drink depends on your:

  • Size:You should drink, in ounces, half your body weight in pounds every day. For example, if you are 200lbs (90kg) should drink 100oz (3 liters) of water a day.
  • Diet:Excessive salt, sugar and processed food, which is very common in our modern diet, mean we require more water.
  • Air conditioning: This decreases water content in the atmosphere, leading to increased water loss from the lungs and through our skin.
  • Activity: If you spend the day sitting, you’ll need less water than someone who works or walks outdoors.
  • Diuretics: Drinks that contain caffeine or alcohol lead to increased urination.

As our bodies become more accustomed to chronic dehydration, we lose sensitivity to our water deprivation. Essentially, our thirst center in our brain stops telling us that we are dehydrated because it becomes desensitized to lower water levels.

Effects of chronic dehydration on the body
Overall, a lack of water slows down the metabolism – just 16 oz or 475ml raises the metabolism by 30%. Drink water before, during and after meals to lose weight. We also frequently overeat because we are thirsty.

In the long-term, chronic dehydration can also lead to constipation and gastric acidity, bad breath, sugar cravings, muscle weakness or cramps, accelerated wear and tear of knee joints, chronic fatigue, increased cholesterol, premature aging, acne and dry skin. It can also lead to kidney stones.

Chronic dehydration also reduces blood supply to the brain, resulting in memory loss, lack of concentration, reduced problem-solving skills and a bad mood. Dehydration makes us dangerous drivers as it reduces our reaction time – like alcohol does – and our concentration.

How do we test for chronic dehydration?
Well-hydrated people urinate between 4-7 times a day. Healthy urine is light or pale yellow and does not smell bad. A good doctor may use a urinalysis to check how dehydrated you are.

Treatment of chronic dehydration
The best treatment is to drink pure water from a glass bottle or from thick plastic. Drinks that are caffeinated, such as coffee, black tea and soda, don’t hydrate because they are dehydrating diuretics. In order to replace the electrolytes and fluids lost, eat lots of veggies and fruits, which are easy to digest. Avoid juices, even fresh ones, as they lack fiber, stimulate hunger and contain natural sugar.

Another great treatment solution is to use IV rehydration therapy. If severely dehydrated, intravenous (IV) rehydration under medical supervision is great because vitamins and minerals and memory-boosting supplements like glutathione or anti-cancer high-dose vitamin C can be added to the IV.

IV therapy in conjunction with chelating agents can help your body wash out the dangerous accumulated toxins from toxic food and air. The solution for pollution is dilution!

How long does it take to reverse chronic dehydration?
Depending on the severity of the dehydration, reversal takes about 1-2 weeks. Drink the majority of the water during the morning and early afternoon so that you do not disturb your sleep at night from frequent trips to the bathroom. This way it will also keep your brain awake and your body energetic all day.

Dehydration: Why It Is So Dangerous

Dehydration Treatment Plans

Why is Dehydration so Dangerous?

Acute diarrhoeal diseases are among the leading causes of mortality in infants
and young children in many developing countries. In most cases, death is
caused by dehydration. Dehydration from diarrhoea can be prevented by giving
extra fluids at home, or it can be treated simply, effectively, and cheaply in
all age-groups and in all but the most severe cases by giving patients by
mouth an adequate glucose-electrolyte solution called Oral Rehydration Salts
(ORS) solution.

During diarrhoea there is an increased loss of water and
electrolytes (sodium, chloride, potassium, and bicarbonate) in the liquid
stool. Water and electrolytes are also lost through vomit, sweat, urine and
breathing. Dehydration occurs when these losses are not replaced adequately
and a deficit of water and electrolytes develops. The volume of fluid lost through the stools in 24 hours can vary from 5 ml/kg
(near normal) to 200 ml/kg, or more. The concentrations and amounts of
electrolytes lost also vary. The total body sodium deficit in young children
with severe dehydration due to diarrhoea is usually about 70110 millimoles per
litre of water deficit. Potassium and chloride losses are in a similar range.
Deficits of this magnitude can occur with acute diarrhoea of any etiology. The
most common causes of dehydration are rotavirus, enterotoxigenic Escherichia coli
(ETEC) and, during epidemics, Vibrio cholerae
O1 or O139. Dehydration is the loss of water and salts from the body. The human body needs water to maintain enough blood and other fluids to
function properly. Along with the fluids, the body also needs
electrolytes, which are salts normally found in blood, other fluids, and
cells. The body may lose fluids in a variety of ways:

  • when urinating
  • when you vomit or have diarrhoea
  • when sweating
  • from the lungs during normal breathing.

If the body loses a substantial amount of fluids and salts
and they are not quickly replaced; for example: by drinking, the body starts
to “dry up” or get dehydrated. Severe dehydration can cause death. The usual causes of dehydration are a lot of diarrhoea
and vomiting. Dehydration can also occur if you do not eat or drink much
during an illness or if you do not drink enough during or after strenuous
exercise. Medications that cause fluid loss to control excess body fluid
(diuretics) are a common long-term cause. Although anyone can become dehydrated, those who become dehydrated the most
easily are:

  • babies under 1 year old
  • the elderly
  • anyone who has a fever
  • people in hot climates.

Dehydration caused by diarrhoea is one of the
biggest single killers of children in the modern world and diarrhoea itself is one of the
major causes of nutritional loss and poor growth.
This year, about 2.2
million children will die of dehydration caused by diarrhoea –
80% of them in the first two years of their life.

are the symptoms of dehydration? The degree of dehydration is graded according to signs and symptoms that
reflect the amount of fluid lost:

In the early stages of dehydration, there are no signs or symptoms. Early features are difficult to detect but include dryness
of mouth and thirst

As dehydration increases, signs and symptoms develop. These
include: thirst, restless or irritable behaviour, decreased skin turgor, dry mucous
membranes, sunken eyes, sunken fontanelle (in infants), and absence of tears when crying
vigorously. Symptoms of early or mild

  • flushed face
  • extreme thirst, more than normal or unable to drink
  • dry, warm skin
  • cannot pass urine or reduced amounts, dark, yellow
  • dizziness made worse when you are standing
  • weakness
  • cramping in the arms and legs
  • crying with few or no tears
  • sleepy or irritable
  • unwell
  • headaches
  • dry mouth, dry tongue; with thick saliva.

Symptoms of moderate to severe

  • low blood pressure
  • fainting
  • severe muscle contractions in the arms, legs, stomach, and back
  • convulsions
  • a bloated stomach
  • heart failure
  • sunken fontanelle – soft spot on a infants head
  • sunken dry eyes, with few or no tears
  • skin loses its firmness and looks wrinkled
  • lack of elasticity of the skin (when a bit of skin lifted up stays folded
    and takes a long time to go back to its normal position)
  • rapid and deep breathing – faster than normal
  • fast, weak pulse

In severe dehydration, these effects become more pronounced
and the patient may develop evidence of hypovolaemic shock, including: diminished
consciousness, lack of urine output, cool moist extremities, a rapid and feeble pulse (the
radial pulse may be undetectable), low or undetectable blood pressure, and peripheral
cyanosis. Death follows soon if rehydration is not started quickly.

From Wikipedia, the free encyclopedia

Dehydration (hypohydration) is the removal ofwater (hydor
in ancient
Greek) from an object. Medically,
dehydration is a serious and potentially life-threatening condition in which
the body contains an insufficient volume of water for normal functioning.

The term “volume depletion” is similar to dehydration, but it refers to the
loss of salts as well as water. Also see

Medical causes of dehydration

In humans,
dehydration can be caused by a wide range ofdiseases
and states that impair water
homeostasis in the body. These include:

  • External or

    stress-related causes

  • Other causes of obligate water loss
Symptoms and prognosis

may include
headaches similar to what is experienced as ahangover,
a sudden episode ofvisual
snow, decreased
blood pressure (hypotension),
dizziness orfainting
when standing up due to
orthostatic hypotension. Untreated dehydration generally results indelirium,
unconsciousness, anddeath.

Dehydration symptoms generally become noticeable after 2% of one’s normal
water volume has been lost. Initially, one experiencesthirst and
discomfort, possibly along with loss ofappetite
and dry skin.Athletes
may suffer a loss of performance of up to 50%, and experience
flushing, low endurance, rapidheart
rates, elevated body temperatures, and rapid onset of

The symptoms become increasingly severe with greater water loss. One’s
heart and
respiration rates will increase to compensate for decreased
plasma volume and
blood pressure, while body temperature may rise because of decreased
sweating. Around 5% to 6% water loss, one may become groggy orsleepy,
experience headaches ornausea, and
may feel tingling in one’s limbs (paresthesia).
With 10% to 15% fluid loss, muscles may become spastic, skin may shrivel and
wrinkle, vision may dim, urination will be greatly reduced and may become
painful, and delirium may begin. Losses of greater than 15% are usually fatal.


Correction of a dehydrated state is accomplished by the replenishment of
necessary water and electrolytes (rehydration).
Even in the case of serious lack offresh
water (e.g. atsea or in adesert),drinkingseawater
or urine does
not help, nor does the consumption ofalcohol. It
is often thought that the sudden influx ofsalt into the
body from
seawater will cause the
cells to dehydrate and thekidneys to
overload and shut down but it has been calculated that average adult can drink
up to 0.2 liters of seawater per day before the kidneys start to fail.

When dehydrated, unnecessarysweating
should be avoided, as it wastes water. If there is only dry food, it is better
not to eat, as water is necessary fordigestion.
The best treatment for minor dehydration is consumption of an
electrolyte-balanced fluid like a sports drink. For severe cases of
dehydration wherefainting,
unconsciousness, or any other severely inhibiting symptom is present (the
patient is incapable of standing or thinking clearly), emergency attention is
required. Fluids will be given through an IV, and within a few hours, the
patient will return to normal unless a complication occurs.

Avoiding dehydration

A person’s body loses, during an average day in atemperateclimate
such as the
United Kingdom, approximately 2.5litres of
water. This can be through thelungs aswater
vapor, through theskin assweat, or
through the
urine. Some (a less significant amount, in the absence ofdiarrhea)
is also lost through thebowels.

During vigorous exercise or in a hot environment, it is easy to lose
several times this amount. Heavy exercise in high temperatures could cause the
loss of over 2.5 litres of fluid per hour, which exceeds the body’s absorptive

Ethical concerns over death by dehydration

Judge Lynch of the
Massachusetts Supreme Judicial Court argued that death by dehydration
symptoms was “cruel and violent” in his opinion on the
1986 Brophy case:

  • The mouth would dry out and become caked or coated with thick material.
  • The lips would become parched and cracked.
  • The tongue would swell, and might crack.
  • The eyes would recede back into their orbits and the cheeks would become
  • The lining of the nose might crack and cause the nose to bleed.
  • The skin would hang loose on the body and become dry and scaly.
  • The urine would become highly concentrated, leading to burning of the
  • The lining of the stomach would dry out and the sufferer would
    experience dry heaves and vomiting.
  • The body temperature would become very high.
  • The brain cells would dry out, causing convulsions.
  • The respiratory tract would dry out, and the thick secretions that would
    result could plug the lungs and cause death.
  • At some point within five days to three weeks, the major organs,
    including the lungs, heart, and brain, would give out and the patient would

Be advised that death due to dehydration can occur in 3 days (or less in
hot weather) and no one normally lives more than about 5-6 days without water.

90,000 What happens to the body after five, twenty-five and seventy-five hours without water

Dehydration quickly destroys the human body

In the heat, adequate fluid intake is vital for humans.

For the normal functioning of the body, nutritionist of the German Institute for Sports Nutrition Gunther Wagner advises drinking up to two and a half liters of water per day.

According to him, an active person weighing 70 kg loses about 0.2 liters of water per hour. Due to a lack of fluid, the blood thickens, more slowly delivers oxygen and nutrients to the organs.

This is what happens to our bodies due to dehydration.

  • 5 hours without water. Within five hours people begin to feel thirst and discomfort, they need more effort to move, body temperature and pulse increase. Concentration, ability to react and learn decrease, and it becomes more difficult to listen to the interlocutor.

  • 10 to 24 hours without water. If a person who weighs 70 kg does not consume fluids during the day during physical activity, this corresponds to a loss of water of about two and a half liters, or four percent of body weight.Circulatory problems, headaches and dizziness appear.

  • Second day without water. On the second day, a person experiences shortness of breath, problems with walking and speaking, numbness of the limbs, a strong decrease in mental performance. The person’s condition becomes critical.

  • After 48 hours. A person weighing 70 kg has a water deficit of about ten percent of body weight.He becomes delirious, cannot swallow, problems with hearing and vision, the skin dries out.

  • More than three days. On the third day, the moisture deficit ranges from 11 to 20 percent based on body weight. With a water shortage of more than 20 percent, people die. Death from fluid deficiency is accompanied by cramps, a swollen tongue, and painful urination.

Earlier, “Kubanskie Novosti” told about the dangers of excessive water consumption.

90,000 What kind of water to drink and how to know if you are dehydrated?

C specialists from chit yt , which is most useful to drink water at room temperature or heated.

Such water is better absorbed and cleanses the body.Hot water is useful in the morning on an empty stomach, because it helps to start the body, freeing it from toxins and thereby speed up the metabolism. Health directly depends on how and in what combinations you use water. Drinking cold water after a heavy fatty meal makes it difficult to digest the food lump. But diluted with warm, hot water, and therefore mushy food leaves the stomach faster. Healthy people can drink both warm water and water at room temperature – at will.Cold water and drinks are contraindicated for everyone. Any meal can be completed with fluid intake. You should definitely drink if you ate spicy, very fatty, very dry food. If you don’t feel like drinking after eating, then you don’t need to. You should not drink fruits, starchy foods, protein foods for 1-2 hours.
Mineral th water a

Mineral water differs from ordinary water in that it contains a higher concentration of salts (at least 1 g per liter of water) and special healing mineral components that are absent in ordinary tap water.Mineral waters can be roughly divided into table, medical-table and medicinal. If the label contains the word “canteen”, it means that you can drink it without a doctor’s prescription, but you cannot use medicinal water without consulting a doctor (it is drunk in small quantities for therapeutic or prophylactic purposes, and has a number of indications and contraindications for use) …

Distilled water

Distilled water is perfectly pure, but does not contain salts, therefore it is harmful to the body.With prolonged use, distilled water “flushes” many of the necessary salts from the body. In limited doses, distilled water is used for arthritis, gout, and kidney disease.
B tap water
The composition of tap water varies greatly from the intake. The tap water (especially in spring) gets waste water, which contains the remains of feces, larvae and eggs of parasites. In terms of the content of copper, lead, manganese, fluorine and iron, this water often exceeds the permissible values ​​by tens of times.Nitrates and salts of heavy metals remain even after boiling, and these are carcinogens that affect the work of the heart and blood vessels.

The use of chlorinated water significantly increases the risk of blood cancer. Therefore, it is advisable to clean tap water using filters.

How to avoid dehydration?

Dehydration is a condition of the body in which the fluid content in it falls below the physiological norm.The loss of only 1% already leads to frustration. Loss of 20% of water can be fatal. Many people know that doctors recommend drinking 1.5–2 liters of liquid during the day. But not everyone takes the advice. But in vain. Because a violation of the drinking regime can lead to serious health problems. It is a mistake to think that thirst is a sign of dehydration. The body, long before the transition to a pathological state, begins to signal the need to replenish stocks.

The simplest test for fluid content in the body.Pinch the skin on the back of your hand. If the fold straightens right away – there is enough water, if it persists – it’s time to drink. If a person finds himself in a situation where he is deprived of any sources of fluid, his body will react with specific symptoms – a feeling of dry mouth, weakness, feeling tired and drowsy. As well as an increase in body temperature, the appearance of dark circles under the eyes, dizziness, and as a result – a decrease in the volume of urine.

There are several reasons for a violation of the water-salt balance in humans.This condition is caused by diseases that are accompanied by fever, vomiting, indigestion, sweating. Overheating in the sun and active sports are the next most frequent occurrences of water shortages. In addition, general dehydration of the body occurs in the following situations: adherence to a low-carb diet. In this case, glycogen is actively consumed, and with it a lot of fluid is lost. After a stormy drunken party, there is a strong thirst, dry skin. This is because alcohol acts as a diuretic.In addition, fluid retention occurs in tissues and cells, and the production of some hormones is inhibited. Irritable Bowel Syndrome. With this pathology, a person suffers from frequent diarrhea. Also, when taking medications, dehydration is possible. After all, some drugs and herbs have a strong diuretic effect.

What if you are dehydrated?

For mild forms of dehydration, if there is no vomiting, oral rehydration can be done.For this, water-salt solutions are used. It is effective to use Rehydron powder, which you can prepare yourself by dissolving the contents of the package in water. The volume of the drunk solution is determined by the state of severity. If there are no preparations with electrolyte formulations at hand, then it is recommended to prepare glucose-saline solution at home. To do this, dissolve half a teaspoon of kitchen salt and the same amount of soda in one liter of water. Then add 4 tablespoons of sugar. Mix everything thoroughly.It is necessary to take it in the same way as pharmaceutical preparations.

Doctors do not recommend drinking soft drinks, juices and the like to eliminate dehydration.
It will not restore sufficient body fluids and electrolytes in the
blood. In severe, critical conditions, they turn to
to the doctor.

Alcohol and dehydration: how does excess alcohol become dehydrated?

Excessive alcohol consumption can cause dehydration in a variety of ways.

First, alcohol reduces the body’s production of antidiuretic hormone, which is used by the body to absorb water. With less antidiuretic hormone, your body loses more fluid than usual due to increased urination.

Second, drinking excessive amounts of alcohol can also cause vomiting, which depletes the body of fluids and can cause further dehydration.Exposure to alcohol varies from person to person, but in general, the less a person weighs, the less alcohol it takes to cause dehydration or vomiting.

The National Board of Health and Medical Research recommends that men and women drink no more than four standard drinks at a time. Drinking in excess of this is considered excessive and may increase the risk of alcohol-related injury.

  1. What signs and symptoms should I be aware of?

If you are concerned that you may be drinking alcohol dehydrated, look for the following symptoms:

  • Dry, clammy mouth
  • Drowsiness or tiredness
  • Thirst
  • Decreased urination
  • Headache
  • Dizziness or delirium
  1. How Can I Prevent Dehydration If I Know I Will Drink Alcohol?

Drinking water along with alcoholic beverages can help prevent dehydration.Drink a glass of water before you start drinking alcohol, and alternate alcoholic drinks with water throughout the evening. Drinking a glass of water before bed will also help reduce dehydration. An electrolyte solution is a good alternative to water, which not only provides water but also valuable electrolytes.

How do I treat the symptoms of dehydration after drinking too much?

Even if you feel good the morning after heavy drinking, alcohol has a lasting effect that reduces your ability to function at your best.Electrolyte replacement solutions and decoctions are ideal for replacing sodium and potassium that are lost through alcohol consumption. Drink plenty of fluids, especially rehydration fluids, and try to get as much rest as possible.

Milk saves better than water from dehydration – Rossiyskaya Gazeta

A group of scientists studied the effect of 13 common drinks when they are consumed in a state of dehydration.Studies show that water is not the best drink for a body that needs hydration.

Experts selected 72 healthy, physically active men aged 18 to 35 years and divided them into three groups. During the study, each participant drank still water, as well as three of the following drinks, which were randomly selected for them: cola, diet cola, Powerade sports drink, oral rehydration solution, orange juice, light beer, hot black coffee, hot black tea, iced black tea, whole milk (3.6% fat), or skim milk (0.1% fat).

In general, the best effect on dehydration was shown by drinks containing a small amount of sugar, fat or protein, which better retain fluid in the human body than water. Skim milk – which has some fat, some protein, sugar lactose, and some sodium – worked best for the study participants. The sodium in milk “acts like a sponge and retains water in the body and leads to a decrease in urine production,” the scientists said in a report. In addition, these substances help slow down the flow of fluid from the stomach and maintain hydration for a longer period of time.

Researchers also reminded that the kidneys and liver need a normal amount of water to cleanse the body of toxins. Water maintains the elasticity and firmness of the skin.

The scientists also found that fruit juices and colas were more hydrated during the first four hours, however, they were unable to act for a longer amount of time due to their high sugar concentration. When this sugar enters the small intestine, water is pulled out of the body to dilute it.This leads to dehydration of the body.

By the way

According to the portal ajc.com, only the production of reusable drinking water bottles in the world costs 7.6 billion dollars a year, and by 2023 this figure will increase to 10 billion dollars a year.

How to avoid dehydration in case of poisoning

Restoration of water balance

  • Control symptoms at home. Most food poisoning can be managed without medical attention.Symptoms may appear several hours after poisoning and may last for hours or days, and in some cases longer. Symptoms of food poisoning include nausea, vomiting, watery diarrhea, abdominal pain and cramps, increased sweating, and high fever.
  • Drink a little water. It may take about an hour for your stomach to calm down, but you should start drinking fluids after that to prevent dehydration. Sip some liquid that is easily absorbed by your body, and try to drink as much as possible throughout the day.Sip the water or suck on crushed ice. Drinking in small sips will help relieve nausea and provide the body with small, but constant doses of much-needed fluids.
  • When ready, start drinking clear broth. Drink the clear chicken, vegetable, or beef broth little by little once your stomach is calm enough to prevent nausea and vomiting. Broth is a good way to restore fluid stores and provide the body with the nutrients it needs.Switch to foods that are soft, low-fat, and easily digestible. These include salted crackers, toast, and gelatin. However, stop eating solid foods if they cause nausea.
  • Avoid drinks that can dehydrate you. Certain drinks are not recommended when you are sick when you are trying to rehydrate. Some fluids help remove water from body tissues and thus contribute to dehydration.During illness, you should not drink alcohol. Avoid caffeinated drinks such as coffee, tea, cola, and energy drinks. Fruit juices and beverages contain carbohydrates and low amounts of sodium, and they can worsen indigestion. Refrain from dairy products, spicy and spicy drinks until your condition improves.

Monitor your condition

Look for signs of dehydration. Symptoms of food poisoning or some other form of gastroenteritis can cause dehydration very quickly.If fluid loss cannot be restored and symptoms persist, dehydration may occur within the first 24 hours. Signs of dehydration include fatigue, loss of appetite, skin redness and decreased elasticity, poor heat tolerance, dizziness, dark urine, and dry cough. Some of the symptoms are difficult to detect because many of them are similar to those of food poisoning.

Watch the color of your urine. Dark yellow or brownish urine may indicate severe dehydration.

  • If food poisoning is accompanied by lack of urination or very little dark urine, seek immediate medical attention.
  • Dehydration can also cause severe weakness and fatigue. If you are so weak that you find it difficult to move, or are tired and want to sleep all the time, although you get enough sleep, seek immediate medical attention.

Use clean, freshly washed utensils when preparing food. Please be aware that cross contamination is possible.

  • Contamination is possible through the consumption of raw food, such as salads and vegetables, as well as other foods that have come into contact with raw meat or fish.
  • Cutting boards (especially wooden surfaces), knife blades or other cutting tools can become dirty and should be washed thoroughly before use.

90,000 When will water help to cope with a headache

Headache is one of the most common symptoms: 9 out of 10 adults experience it at least once in their life.There are many varieties of this disorder, and in some cases it is easily treatable at home. This happens, for example, with headaches caused by dehydration.

The body requires a balance of water and electrolytes to function optimally. But a person loses water every day when breathing, sweating and urinating. The loss of water is compensated by its intake with drinks and food, but the body loses water faster than it gets. Factors such as diarrhea, vomiting, intense sweating, fever, and frequent urination can cause dehydration.

Dehydration sometimes causes headache, a secondary symptom that can be mild or severe. With a lack of water, the brain may shrink slightly, which causes pain. After the water balance is restored, the brain volume is restored and the pain disappears.

A headache with dehydration can occur in the front, back and sides of the head, and also affect the entire head. Unlike pain associated with sinus pressure, dehydration pain rarely affects the front of the head and does not occur in the back of the neck as with high blood pressure.

With a lack of water, the headache is accompanied by symptoms of dehydration: excessive thirst, infrequent urination, blurred consciousness, dizziness, fatigue, dry mouth, loss of skin elasticity, decreased blood pressure and increased heart rate. Symptoms of dehydration often only occur with severe water loss.

Certain populations are particularly prone to dehydration. Risk groups include young children, the elderly, patients with chronic diseases (such as diabetes and kidney disease), people taking diuretics or living in hot climates, and athletes.

For the treatment of headache caused by dehydration, it is necessary not only to reduce the severity of the pain, but also to restore the water balance. To do this, you should increase your fluid intake, restore the balance of electrolytes in the blood, temporarily reduce physical activity and avoid overheating. Over time, these measures will lead to a decrease in the severity of the headache. If you are severely dehydrated, you should seek medical attention to avoid complications such as kidney damage, seizures, and shock.

Dehydration can be prevented. To do this, you need to consume enough liquid and foods containing a large amount of water (cucumbers, juicy fruits). Scientists recommend spreading water intake evenly throughout the day. In hot weather and during physical exertion, the amount of fluid you drink should be increased. To help your body stay hydrated, you should avoid drinking caffeine and alcohol, and avoiding strenuous physical activity in the heat.

Following these simple guidelines will help you maintain optimal water levels and avoid the unpleasant symptoms of dehydration.
