Can dehydration cause high temperature: Six unusual signs of dehydration you should know about

Six unusual signs of dehydration you should know about

Did you know that our body temperature, skin texture and even our breath can serve as indicators of our hydration or dehydration levels?

First off, before we talk about the signs of dehydration, we should learn about what it is; here is a brief definition of dehydration: quite simply, dehydration occurs when our body cannot function correctly due to low and insufficient water levels.

Although mild dehydration can be inconvenient but tolerable, severe dehydration can cause blood clots, convulsions and other potentially fatal complications. If this is the case, it should be treated immediately. Due to its potential complications, it is important to know how to detect the early symptoms of dehydration. Some common and usual symptoms are feeling thirsty or fatigued. However, there are also other signs of dehydration that are not so obvious. Therefore, we will share with you six unusual signs of dehydration that you should know about.

Bad breath

It is well known that our saliva has antibacterial properties. However, if you are dehydrated, you won’t be able to produce enough saliva to take advantage of this natural aid. Accordingly, if your body is not able to produce sufficient amounts of saliva, you could experience a significant increase in bacterial growth in your mouth. In turn, this increase in bacteria will produce bad breath.

Dry skin

People often believe that someone who is dehydrated will experience continuous and excessive sweating. However, this is not so. In fact, as dehydration becomes more severe, a person’s skin becomes dry, red and irritated. A simple test that can help us to identify this ailment is to apply pressure in a small area of our skin and then letting go immediately. If our skin remains flat and without color, and is slow to gain back its normal appearance, then it’s time to drink abundant water and rehydrate.

Muscle cramps

If you suffer from muscle cramps when performing physical activity or being in hot weather, you could be suffering from dehydration. When you do exercise, you become agitated, your body temperature rises, and you have a higher chance of getting muscle cramps. This is due to the intense heat stroke that hits your muscles. In addition, as your muscles suffer the strain of physical activity, they experience changes. Most commonly, a change in electrolyte, sodium and potassium levels, will provoke muscle cramps.

On the other hand, you can also suffer from dehydration in cold climates if you don’t drink enough water while performing physical activity. According to several studies, dehydration symptoms in colder climates can appear slowly and feel milder, but the risks of this ailment remain the same. Therefore, as you have learned, we can experience dehydration both in hot and cold weathers.

Fever and chills

If you have severe dehydration, you are also likely to experience fever and chills. Fever, in turn, will make dehydration even worse. Thus, the higher the fever, the higher the dehydration level that you will encounter. Adults with fever should seek medical care whenever they have a body temperature higher than 104°F.

Babies and kids can also suffer from this ailment (dehydration in children) due to many causes, such as not drinking enough water, diarrhea, fever and vomit. Of these causes, fever is the most serious ailment to watch out for when kids and babies are dehydrated. In this case, we recommend visiting a pediatrician as soon as possible.

Food cravings

Dehydration can cause complications in several body organs. The liver is a body organ that is very sensitive to this ailment, as it needs water to release glycogen (a glucose based source of energy) and other chemical components. This is why, when you are dehydrated, you will experience low levels of energy and get strong food cravings (specially sugar cravings).

Remember that our body can have a false sense of feeling hungry, when in fact it is feeling thirsty. This means that sometimes you will feel hungry, when all you really need is to drink abundant water.


Did you know that even mild dehydration can cause a severe headache and even a migraine? Because it’s hard to know what is the actual cause of a headache, drinking a glass of water and maintaining optimal hydration levels every day is a simple and safe way to prevent or alleviate a headache.

Frequently Asked Questions about Dehydration

How Long Does it Take to Recover From Chronic Dehydration?

Recovering from dehydration really depends on the cause and on how long you’ve been dehydrated. If your symptoms are severe that it requires medical attention and hospitalization, the recovery time may take a day or two. However, once the emergency has passed, you will need to follow a treatment that will probably last for a few weeks.

What are Severe Dehydration Symptoms?

When you’re dehydrated, you may experience dark colored urine, muscle fatigue, dizziness, and extreme thirst. Nonetheless, severe or chronic dehydration presents a bit differently because the body becomes less sensitive to water intake and tries doing regular activities with less water inside. Some signs of severe dehydration include:

  • dry skin
  • constipation
  • fatigue
  • muscle weakness
  • headaches

Does Dehydration Cause Low Blood Pressure?

Yes, when left untreated, chronic dehydration has been linked to other health conditions like high blood pressure and kidney stones. Research has shown that when your dehydration is severe or prolonged, you may have an underlying illness. As well, dehydration has been linked to urinary tract infections, intestinal failure, and dementia.

When to Worry About Dehydration?

Either severe, chronic, or mild, dehydration is a serious condition that should never be ignored. Symptoms such as nausea, headaches, dizziness, and muscle cramping are some signs that you need to drink more water. However, if you experience any of the unusual sings that we mention before call your doctor or approach to the emergency room.          

Southwest Health | Beyond Thirst: Signs You’re Dehydrated

Posted on by Southwest Health

The average human is about 60% water. True. Dehydration (when your body does not have enough water to function properly) can cause blood clots, seizures, and other potentially fatal health issues. That’s unfortunately true, too.

In fact, even mild dehydration can cause problems, so everyone should know about the not-so-obvious signs of dehydration that don’t include being thirsty.

  1. Fatigue: Being even mildly dehydrated can affect your moods and energy levels.
  1. Increased appetite or cravings: dehydration impacts your body’s nutrients and organs, like the liver, that use water to release energy stores. Though you might crave almost anything, hunger for something sweet is common because your body is having difficulty producing glycogen. So, while something sweet may satisfy you in one way, it may be that what your body really needs is water.
  1. Headaches: the human brain is big, and it requires a lot of water to keep it sitting comfortably in your skull.
  1. Dry skin: while hot weather makes you sweat, losing too much results in the opposite of what you might think. By the way, you can find yourself dehydrated in colder weather as well as hot days. If you’re really dehydrated, the hair on your skin may stand on end. One easy test to help you see if you’re dehydrated is to pinch the skin on the back of your hand. If it bounces back in a few seconds, your fine. If it doesn’t return quickly to normal, you’re probably dehydrated.
  1. Muscle cramps: while heat and exertion may be enough to cause cramping muscles, reductions in blood volume with exercise and sweating can cause imbalances in electrolytes, like sodium and potassium.
  1. Fever and chills: as counter-intuitive as it sounds, extreme dehydration can cause a dangerous spike in your body temperature. With a fever over 101 degrees F, you may need medical attention.
  1. Darker urine: if you’re reasonably well-hydrated, your urine will be clear with perhaps a tinge of yellow. If you’re dehydrated, it gets more yellow, and the more dehydrated you are, the darker it becomes. Orange urine (or not having to go at all over a lengthy period) indicates severe dehydration.

Staying Hydrated

  1. Keep a water bottle handy and sip regularly. Room temperature water is best for absorption by your stomach.
  1. Drink more at mealtimes.
  1. Eat fruit. Apples, oranges and other delectable fruit is not only good for you and good tasting but also contains lots of water.
  1. Try some of the sugar-free flavorings for water available at your supermarket. Or, pop a piece of fruit into your water for added flavor. You might also try caffeine free teas. Steer clear of caffeinated beverages, however, as they are a diuretic and tend to exacerbate dehydration.

How much water you need on a daily basis varies widely depending on your gender, your activity level, environment, and your body size. If you regularly experience any of the above symptoms, however, it’s a safe bet you don’t currently get enough.

Signs and symptoms of dehydration – Doctor TV channel

Unfortunately, thirst is not a good indicator of the body’s need for fluid both during exercise and at rest

Early signs and symptoms of dehydration include mild dizziness, headache, loss of appetite, dark urine and fatigue – this is described by the doctor, general and sports nutritionist Monique Ryan in her book “Nutrition in Endurance Sports. Everything a runner, swimmer, cyclist and triathlete needs to know.

As long as you feel thirsty, 1% of your body weight will be lost with fluid, and losing only 1-2% already leads to worse results. If weight loss exceeds 4%, severe thirst, irritability, nausea, and other symptoms may occur. Dehydration also leads to gastrointestinal disturbances.

Therefore, drinking after dehydration has begun will cause abdominal discomfort. With a loss of 5-6% of body weight, heart rate and breathing will become more frequent, and the regulation of body temperature will be disturbed. Don’t forget that dehydration affects your concentration and ability to perform the actions you need in your sport. Clearly, impairments in coordination, decision making, and focus due to fluid loss reduce performance. The longer and more intense the load, the higher the risk of the negative impact of fluid loss through sweat. Sweating is affected by heredity, fitness level, and acclimatization to the temperature in which you exercise. Although a person sweats more in warm weather, the same risks persist in cold weather with a heavy load. By preventing dehydration, you are likely to avoid the following detrimental physiological effects:

– increased heart rate;

– elevated body temperature;

– decrease in blood volume;

– decrease in cardiac output per minute;

– reduced blood flow in the skin;

– hypertrophied perception of effort;

– disorders of concentration;

– violations of fine motor skills;

– delays in the release of fluids from the stomach;

– increased risk of gastrointestinal problems.

Severe effects of dehydration

Of course, dehydration can lead to more serious health risks, including heat exhaustion and heat stroke. In the first case, weakness, clouding of consciousness, fatigue and nausea occur, the skin becomes cold and clammy, and the pulse is barely perceptible. If the fluid loss is even greater, the athlete may even stop sweating and the skin will appear dry and cold. Due to the weakening of blood flow in the brain, the athlete will be in a semi-conscious state. In such a situation, immediate medical attention is required. Heatstroke is an even more serious condition in which the skin is hot and dry and the body temperature is very high. This problem most often occurs due to overexertion in very hot environments accompanied by an incorrect hydration strategy. Past illnesses, poor preparation for training at high air temperatures, and even certain medications can increase the risk of the conditions described above.
