How to Rehydrate: 6 Helpful Tips

Your body needs hydration to function. In addition to water, there are several fast ways to cure dehydration and rebalance your body, such as oral rehydration solutions and fruit.

It’s important to rehydrate after any activity that causes heavy sweating, such as an intense workout, sauna session, or hot yoga class.

Rehydrating is also crucial for preventing the damaging effects of dehydration if you have diarrhea or are recovering from a night out.

This article explains some ways to rehydrate quickly at home and some tips on how to recognize dehydration.

While it likely comes as no surprise, drinking water is most often the best and cheapest way to stay hydrated and rehydrate.

Unlike many other beverages, water contains no added sugars or calories, making it ideal to drink throughout the day or specifically when you need to rehydrate, such as after a workout.

It’s worth noting that a variety of factors, including genetics, cause some people to lose more sodium via their sweat than others. You might be a “salty sweater” if you get frequent muscle cramps with exercise or if your sweat stings your eyes.

If either of these apply to you, make sure to replace not just the fluid you lose through sweat but also the sodium, particularly after intense or long bouts of exercise in hot environments.

That said, unless you’re participating in a long, intense activity like an ultra-endurance event in a hot environment, the sodium you lose through sweat can easily be replaced through a balanced diet.

Summary

For most people, drinking water is sufficient to rehydrate. If you’re a salty sweater, be sure to replace both the sodium and fluid you lose through sweat, preferably through a balanced diet.

Sports drinks contain water, electrolytes, and other ingredients. Some of these drinks may be as effective as water at helping you rehydrate or stay hydrated in hot weather or during intense exercise. If you like the taste, you may also be inclined to drink more.

It’s worth noting that some sports drinks are high in calories, added sugars or artificial sweeteners, which may not benefit your overall health. Check the ingredients before you choose a sports drink.

Should you drink sports drinks instead of water?

Summary

Sports drinks have a similar effect to water, but they may be high in calories and have added sugars and artificial sweeteners. Check the ingredients first.

In addition to supplying a host of nutrients, milk has excellent hydrating properties.

Milk naturally contains high concentrations of electrolytes, which help balance the amount of water in your body.

Research has shown that skim and low fat milk rehydrate you as well as popular sports drinks after intense exercise, all while providing protein and other important nutrients.

The high quality protein in milk also makes it an ideal post-exercise beverage for kick-starting muscle repair and the rebuilding process.

Just keep in mind that consuming milk after exercise may cause stomach discomfort like bloating. Plus, it’s not suitable for people with an intolerance to lactose or certain milk proteins.

Full fat milk in particular might also not be a good option if you have diarrhea or vomiting, as it could worsen these symptoms.

Is milk good for dehydration?

Summary

Skim and low fat milk can be used as an effective post-workout or general rehydration beverage if you don’t have lactose intolerance or a milk protein allergy.

Comprising 80–99% water, fruits and vegetables make for a perfect hydrating snack.

For comparison, highly processed foods like cookies, crackers, cereals, and chips contain only 1–9% water.

Fruits and vegetables with the highest water content include:

• berries
• melons
• oranges
• grapes
• carrots
• lettuce
• cabbage
• spinach

Stock up on a variety of fresh fruits and vegetables and keep cubed watermelon in your fridge for easy and convenient access.

Frozen fruits and vegetables are just as nutritious as their fresh counterparts, and in some cases, they’re more nutritious.

It can take days or weeks before fresh fruits and vegetables make it to your plate. During that time, oxidation can cause nutrient loss. On the other hand, frozen fruits and vegetables are frozen shortly after harvesting, which retains most of their nutrients.

For example, one study showed that frozen green beans and blueberries contained more vitamin C than their fresh counterparts.

Try making a hydrating, nutrient-packed smoothie by combining your favorite fresh or frozen fruits and vegetables in a blender along with milk or Greek yogurt.

Which foods help you stay hydrated?

Summary

Due to their high water content, both fresh and frozen fruits and vegetables make a perfect hydrating snack.

Oral rehydration solutions are specialized formulas used to prevent and treat dehydration caused by diarrhea or vomiting.

They have also been promoted to bolster exercise recovery and prevent or treat hangovers.

These solutions are water-based and commonly contain electrolytes like sodium, chloride, and potassium, as well as sugar, typically in the form of dextrose. Some commercial solutions also contain other ingredients like prebiotics and zinc.

While these rehydration drinks help replace lost fluids and electrolytes, they can be expensive.

Fortunately, you can make your own using these common kitchen ingredients:

• 34 ounces (1 liter) of water
• 6 teaspoons of sugar
• 1/2 teaspoon of salt

Combine them in a large bowl or pot and stir until the sugar and salt dissolve. You can use flavor enhancers to improve the taste if desired — just keep in mind that they may contain artificial sweeteners and flavors.

What’s the best way to use an oral rehydration solution?

Summary

Oral hydration solutions contain water, electrolytes, and sugar. You can make your own simple rehydration solution at home using water, salt, and sugar.

Coffee and tea contain the stimulant caffeine, which can acts like a diuretic in high amounts.

While not as rehydrating as water, moderate amounts of coffee and tea can help you stay hydrated.

Caffeine becomes dehydrating only in doses around 250–300 mg, the equivalent of two to three 8-ounce (240-ml) cups of coffee, or five to eight 8-ounce (240-ml) cups of tea.

In a study, 50 regular coffee drinkers drank 4 cups (800 ml) of coffee containing 1.8 mg of caffeine per pound (4 mg per kg) of body weight daily. The authors observed no significant differences between coffee and water in regards to hydrating ability.

If you don’t like these beverages plain, try adding unsweetened almond milk to your coffee, or herbs and spices like cinnamon, nutmeg, or lemongrass to your tea.

Does coffee dehydrate you?

Summary

Drinking moderate amounts of coffee and tea have similar hydrating properties as water. Plus, their caffeine content may give you an energy boost.

Every cell, tissue, and organ in your body requires water to function.

Water helps regulate body temperature, lubricate joints, transport nutrients, remove waste, and circulate blood. That means your body can’t properly perform these functions if you’re dehydrated, which happens when you lose more fluids than you take in.

For example, you can become dehydrated from sweating, vomiting, experiencing diarrhea, or taking diuretic medications that increase fluid loss.

Certain populations are more prone to dehydration than others, including children, older adults, and people with certain medical conditions like diabetes and kidney disease.

The signs and symptoms of dehydration include:

• increased thirst
• dry mouth
• infrequent urination
• dry skin
• tiredness
• dizziness
• headache

Urine color is also a common indicator of hydration status. Generally, the paler the color, the better hydrated you are. That said, the color can change for reasons other than your hydration status, including diet, certain medications, and some medical conditions.

Are you dehydrated? Your pee color can give you a clue.

What is the quickest way to rehydrate your body?

Water is the best option for rehydrating your body, but oral rehydration solutions also provide essential electrolytes. These may be useful if you are dehydrated due to diarrhea or vomiting, or if you have been exercising intensely.

Severe dehydration may need medical treatment, where a doctor provides fluid intravenously.

How long does it take to rehydrate your body?

When you drink water, your body starts absorbing it after 5 minutes, and peak absorption can take 15–60 minutes, according to a 2012 study.

This will depend on several factors, such as how much fluid you take in, what type of fluid, how dehydrated you were to start with, and whether the cause of dehydration, such as diarrhea, has gone away.

How long does it take for water to go through your body?

What’s the best way to rehydrate after drinking alcohol?

Water is effective, but oral rehydration solutions can also help relieve dehydration if you have a hangover.

How can you stay hydrated overnight?

Being hydrated can help you sleep better, but it can also mean you need to pee more during the night. Tips for nighttime hydration include:

• drinking sips of water for the last 2 hours before bedtime and if you wake up in the night
• limiting alcohol consumption
• making sure the room is cool enough so you don’t sweat
• eating plenty of whole fruits and vegetables during the day so you don’t go to bed dehydrated

Dehydration occurs when your body loses more fluids than it takes in. For most people, drinking water is the best way to stay hydrated and rehydrate.

Other options include:

• sports drinks
• coffee or tea
• milk
• fruits and vegetables
• oral rehydration solutions

Don’t hesitate to seek medical advice if you or someone else is experiencing symptoms of dehydration, such as dizziness. Severe dehydration is a life threatening emergency and needs urgent medical attention.

Severe Dehydration: Symptoms, Causes & Treatment

Severe hydration is a medical emergency. It’s important to know how to recognize this advanced state of dehydration and know what to do.

You may need intravenous fluids in an emergency room and other treatments to avoid organ damage and other health complications if you experience severe dehydration.

Children, older adults, and those who are pregnant are especially susceptible to serious health problems related to severe dehydration. Let’s take a look.

Dehydration defined

The body is in a state of dehydration when fluid levels drop to a point at which organs and bodily functions, such as circulation and respiration, can’t function normally. It occurs when the body loses more fluids than it takes in.

You can usually remedy mild dehydration by drinking water or drinks packed with electrolytes.

Was this helpful?

• Heat. Excessive sweating due to extreme temperature exposure, such as being active in hot weather or spending too much time in a sauna, may cause dehydration.
• Illness. An illness that triggers bouts of diarrhea or vomiting can also rob the body of fluids in a short amount of time. If you’re vomiting or have diarrhea and you can’t keep down replenishing fluids, mild dehydration can progress into severe dehydration.
• Not drinking enough or often enough. You can also become dehydrated by not drinking enough to keep up with typical fluid loss.
• Medications. If you take certain medications, such as diuretics for high blood pressure, fluid loss may be quicker.

If you don’t notice the early signs of dehydration or you don’t rehydrate soon enough, you can move from being mildly to severely dehydrated.

Symptoms of severe dehydration include:

• Thirst. You may think that feeling thirsty is the first indication that you may become dehydrated. The reverse is usually true: Your body starts to feel thirsty after dehydration has already started.
• Peeing less. In addition to feeling thirstier than usual, the signs of dehydration include less-frequent urination and darker colored urine.
• Not peeing. If you’re not urinating at all, it’s likely you’re severely dehydrated and should get immediate medical attention.
• Not sweating. Without enough fluids to function normally, your body can start to overheat, which can quickly lead to heat-related illnesses, such as heat stroke and heat exhaustion.
• Headache and dizziness. Dizziness and lightheadedness are signs of mild or moderate dehydration. If those symptoms worsen and you have trouble concentrating and communicating, seek medical attention.
• Poor skin turgor. Poor turgor is when your skin takes longer to return to its original appearance after lightly pinching an area.

Severe dehydration can lead to brain damage and even death in some cases.

Older adults need to be especially mindful of staying hydrated as they may be less aware of when they’re thirsty and becoming dehydrated.

Skin fold and dehydration

You can get a sense of how dehydrated you are by pinching or folding your skin between the pads of two fingers. If you pinch the skin on your arm, for example, it should quickly return to its normal appearance once you let go. The term for this kind of skin elasticity is turgor.

If the skin appears to “tent” or sticks together under the surface, it’s usually a sign that you’re severely dehydrated.

In very young children, severe dehydration may be the case when they have:

• no tears accompany crying
• signs of lethargy
• dry diapers for longer than usual
• cold, clammy limbs

Serious health consequences can happen fast in children if severe dehydration isn’t treated quickly.

Symptoms of severe dehydration during pregnancy include:

• extreme thirst
• sunken eyes
• rapid heart rate
• drop in blood pressure
• dry mouth
• dry skin, as well as poor turgor
• early labor

Dehydration can also trigger Braxton-Hicks contractions, which feel like real contractions, but are considered to be signs of false labor.

Rehydrating through severe dehydration usually requires more than providing water or other beverages.

Treatment with intravenous fluids should begin as soon as you can get medical care.

IV fluids are usually a saline solution, made of water, sodium, and other electrolytes. By getting fluids through an IV rather than by drinking them, your body can absorb them more quickly and recover faster.

While in the hospital, your blood pressure and heart rate will probably be monitored to make sure they return to normal as your body recovers.

You’ll also be encouraged to drink water or other hydrating beverages, too.

For children

While sport drinks do contain a lot of added sugar, they also contain water and important electrolytes, such as sodium and potassium.

• A diluted sports drink — 1 part sports drink to 1 part water — may be helpful for children.
• Try giving very young children diluted sports drinks or water a teaspoon at a time. If swallowing is difficult, try using a syringe.

This can help keep fluid levels in a healthy range after mild dehydration or IV rehydration treatment.

When you’re pregnant

You can also rehydrate with water or sports drinks. If you feel nauseated in the morning or any time of day, try to find a time when you’re feeling better to get your fluids down.

Good drinks for rehydrating

Along with water and certain electrolyte sports drinks, soup, milk, and natural fruit juices all count as rehydrating beverages.

Drinks to avoid

Keep in mind that not all beverages help with rehydration.

• Colas and sodas. Sugar-sweetened soft drinks can actually make your dehydration worse and lead to further kidney-related dehydration problems.
• Alcohol, including beer. As refreshing as a cold beer might sound when you’re exceptionally thirsty, you should avoid alcohol if you’re trying to rehydrate.
• Caffeinated drinks. Caffeinated and alcoholic beverages act as diuretics, causing you to urinate more than usual and increasing your fluid loss compared to your fluid intake. This includes coffee, black tea, green tea, and energy drinks.

Severe dehydration is a potentially life-threatening medical emergency. It can cause serious damage to your kidneys, heart, and brain. To avoid severe hydration, respond to signs of dehydration by drinking fluids that rehydrate you.

You can also avoid even the hint of dehydration if you consume fluids throughout the day. How much you should drink depends on several factors, including your age, weight, and overall health.

People with kidney disease, for example, need to drink less than other individuals. People who are physically active need to drink more than others.

If you’re not sure, talk to your doctor. You can also do a quick check by looking at the color of your urine. If you’re peeing regularly each day and the color is almost transparent, you’re probably well hydrated.

Dehydration is a state of increased loss of moisture from the body. Otherwise, this condition is called dehydration or exsicosis. It is characterized by thirst, dry skin, decreased urine output. As the moisture deficit increases, the patient’s blood pressure decreases, the skin becomes pale, there are disturbances in consciousness, pathological changes in the blood composition – an increase in hematocrit. This is the name for an increase in the volume of red blood cells relative to the volume of the liquid part of the blood.

Dehydration is a dangerous condition in which the body needs an urgent restoration of water and electrolyte balance.

How dehydration occurs

Dehydration occurs when the liquid drops to 40–50 ml/kg. In this case, body weight decreases by 4-5% due to the loss of water. In the body, it is found in the blood, cells of organs and tissues, and intercellular space. If water loss as a result of exsicosis reaches 20-25%, tissue ischemia begins – a violation of the blood supply to organs and tissues due to an increase in hematocrit.

Causes of dehydration

Exicosis most often occurs against the background of various diseases and pathological conditions. Among them:

• intestinal infections that cause vomiting and upset stools;

• burns of the second or more degree, in which there is an extensive release of exudate;

• diseases that are accompanied by fever and increased sweating;

• insufficient fluid intake with food;

• diseases accompanied by shortness of breath, in which the body loses moisture due to the release of water vapor.

The most common cause of dehydration is intestinal infections. Up to 48% of all clinical cases of exsicosis are associated with such diseases. They pose the greatest danger to young children. Frequent vomiting and loose stools lead to rapid loss of moisture, which causes dehydration. In countries with a low standard of living and a high incidence of intestinal infections, excoses are one of the main causes of death of young children under the age of 5–6 years.

With extensive burns, a large amount of exudate is released. If the patient does not receive fluid replacement therapy, a fluid deficiency develops.

Increased sweating at elevated body temperature requires control of the drinking regimen. This is especially important if the patient is in a warm room.

Insufficient fluid intake with meals can lead to dehydration if a person voluntarily or deliberately restricts drinking. About one and a half liters of water the body loses per day with sweat, defecation and urination. If the fluid intake is below normal, exsicosis develops.

Dehydration associated with shortness of breath occurs in patients with respiratory and cardiac pathologies. This phenomenon in healthy people is observed when traveling to high mountainous areas due to changes in the composition of the air.

Additional factors

Even healthy people who live in hot regions, do intensive sports or physical labor in hot weather, and stay in the mountains face a moisture deficiency in the body. To avoid dehydration, it is necessary to consume enough water, fresh vegetables and fruits.

Patients taking diuretics and people on mechanical ventilation are also at risk. To prevent exsicosis, patients on mechanical ventilation are injected with saline solutions and moisten the respiratory mixture that enters the body.

What happens when you get dehydrated

When the body loses a lot of moisture, blood viscosity changes first of all. It increases against the background of a decrease in plasma volume. This negatively affects the blood supply to organs and tissues, including the brain. Dehydration leads to an electrolyte imbalance, a decrease in the amount of mineral salts. A decrease in the concentration of potassium, calcium and sodium ions leads to a disruption in the work of the heart.

A patient with severe dehydration has acidosis, which is characterized by an acid-base imbalance. The pH formula shifts to the acid side. This leads to repeated vomiting, after which the person develops metabolic alkalosis. It is manifested by various disorders in the work of the respiratory and cardiovascular systems.

Dehydration types

The classification of exicoses includes their division into several groups depending on the severity of the course, the cause of the development of the pathology, the presence or absence of complications.

The severity of dehydration is mild, moderate and severe. It can be caused by external and internal causes, pass with complications and without them.

When choosing therapy, experts pay attention to the ratio of the loss of mineral salts and water. On this basis, three forms of dehydration are distinguished:

• hypoosmolar. It is characterized by a rapid loss of salts with a slow development of water deficiency. This leads to the rapid onset of negative symptoms from the central nervous system. The patient’s blood circulation is disturbed, signs of a neurological disorder appear;

• hyperosmolar. Fluid loss occurs faster than electrolyte loss. Due to this, their concentration increases. With this kind of dehydration, pronounced symptoms appear only with a significant deficit of moisture;

• isosmolar. The loss of water and salts is about the same. The patient has a decrease in the amount of urine excreted, may decrease blood pressure (BP) and central venous pressure.

Symptoms

Each degree of dehydration is characterized by special signs:

• mild degree. The patient is thirsty, the pulse remains normal, may become more frequent. Skin and mucous membranes are unchanged. On the part of the nervous system, there may be signs of anxiety and anxiety;

• average degree. Externally, the pathology is manifested by dry skin and mucous membranes, a decrease in diuresis. The eyes become sunken, the patient’s pulse quickens, the pressure is increased or decreased by about 20% of the usual values. From the side of the central nervous system, both anxiety and lethargy can be observed;

• severe degree. Pronounced fluid deficiency causes neurological disorders. The patient is very lethargic and practically does not react to anything. Breathing becomes difficult, blood pressure is greatly reduced, tachycardia is characteristic. The skin looks pale and has a bluish tint, it is cold to the touch.

Moderate to severe dehydration increases the risk of complications. First of all, they are associated with the formation of blood clots due to the high viscosity of the blood. When a thrombus clogs the vessels of vital organs, the patient may die or receive irreversible negative changes. Some people who survive severe dehydration develop chronic headaches, weakness, and reduced muscle mobility. Children have cognitive impairment.

Diagnostics

At the first signs of dehydration, it is necessary to contact a medical institution to a general practitioner, a general practitioner, a pediatrician. If dehydration is severe, an ambulance must be called to hospitalize the patient in a medical facility.

For the diagnosis of exicosis, the following are used:

• visual examination and questioning of the patient for the presence of vomiting, diarrhea;

• measurement of arterial and central venous pressure;

• blood test for electrolytes and hematocrit.

A decrease in central venous pressure and an increase in hematocrit above the age norm indicate fluid deficiency.

Treatment for dehydration

With mild dehydration, the patient is treated at home. With moderate and severe fluid deficiency, which are accompanied by changes in the central nervous system, circulatory disorders, hospitalization and intensive treatment are necessary.

The main ways to eliminate exsicosis are:

• the use of rehydrating solutions or large amounts of liquid with the addition of salt to restore water and electrolyte balance;

• intravenous infusion of glucose and saline solutions. It is used in conditions that are accompanied by severe vomiting. Fluid therapy will make up for the lack of fluid if the patient cannot drink it by mouth due to frequent vomiting.

Severe dehydration may require intensive care with a ventilator. With signs of tissue ischemia, neuroprotectors, potassium preparations, drugs to maintain the work of the heart are prescribed.

Treatment is continued until normalization of blood circulation and diuresis. To achieve stable results, it is important to identify the exact cause of the pathological condition and eliminate it.

As a rule, with a slight dehydration, it is possible to completely normalize the patient’s condition within 1-2 days. In moderate and severe dehydration, the prognosis depends on the severity. In some cases, the risk of developing serious violations of body functions, up to irreversible processes, increases.

Prophylaxis

To avoid dehydration, you need to know what factors provoke it, and take appropriate safety measures. This is, first of all, adequate intake of water and fluids. Its volume is from 1.5 liters per day and increases with intense physical exertion, in hot weather.

If the patient has diarrhea or vomiting, rehydration solutions should be used to prevent dehydration. You can buy them at a pharmacy or make your own at home. Pharmacy rehydrating solutions contain potassium chloride, sodium chloride and other mineral salts.

The funds are available in the form of a powder that dissolves in water and is taken orally to prevent water and electrolyte disorders. Powders contain flavoring additives, due to which the use of the drug does not cause discomfort in adults and children.

In addition to powders, rehydrating agents are available as infusion solutions.

Making a rehydrating solution at home

If it is not possible to buy a pharmacy product, it can be seen as a home analogue. To prepare the drink, you need a tablespoon of salt, a teaspoon of soda and two tablespoons of sugar.
