Symptoms of dehydration: what are the symptoms of dehydration and how to deal with it.

For a more or less healthy person, the first and most correct symptom of lack of water in the body is thirst. It equips the human body with excellent self-regulation mechanisms. When these mechanisms work normally, there are no special procedures to determine dehydration.

Trust your body and drink as much as you want. If you still have doubts, look at the color of your urine. Dark urine is a sign of lack of fluid.

You can pinch yourself on the outside of your palm. Water provides osmotic pressure in your cell, making it as elastic as a pumped wheel. When the fluid content drops, the cells “deflate” and lose the ability to resist mechanical action.

This is especially noticeable in the skin. If the skin is quickly smoothed out after a pinch, everything is fine. If the skin is easily stretched, the crease spreads out for a long time, you may need to drink more.

Smooth, wrinkled skin on your hands (laundry hand syndrome) is a classic sign of severe dehydration in some diseases.

Symptoms of severe dehydration, dangerous to life:

  • - extreme fatigue and weakness
  • - dark circles under your eyes
  • - tachycardia (strong heartbeat)
  • - marked improvement in skin elasticity
  • - grey face
  • - leg and arm cramps
  • - dizziness, mental confusion, fainting

When dehydration may occur:

  • - hot weather
  • - Hangover (especially if you not only drank alcohol but also smoked a lot)
  • - physical activity with excessive sweating
  • - feverish diseases
  • - diuretic intake
  • - long-term diarrhoea and vomiting
  • - systemic diseases that affect the water balance in the body, such as kidney diseases

What’s dangerous about dehydration?

On the lightest dehydration, losing fluid is less than 1% of the body. A person feels moderate thirst and dry mouth. This condition is not dangerous for health. The best medicine for mild short-term dehydration is two or three glasses of clean cool water. You can say it’s a common dehydration that occurs, for example, after a long walk on a hot day.

In case of more serious dehydration, the body switches to the economy mode: it emits less sweat and urine. All body systems malfunction. The blood thickens and becomes viscous. Blood circulation slows down, it impairs the supply of oxygen to the cells and their purification from decay products and toxins.

It reduces the amount of blood in the bloodstream, which causes low blood pressure. A person is experiencing dizziness and may faint. It reduces the secretion of digestive glands, it impairs renal function.

Together with fluid, the body loses electrolytes, which maintains osmotic pressure in the cells. The pressure in the cells increases, and water from the cells enters the tissues, resulting in swelling. It particularly affects the brain. There is a confusion of consciousness, fainting, in severe cases, a person falls into a coma.

How to avoid dehydration

A person can live without water for not over two days. If 25% of fluid is lost from the body, death occurs. At 10% serious painful disorders begin, a doctor can cure which. Even a relatively mild lack of water (1-2%) has an adverse effect on health. A person feels weak, tired, attention and quality of thinking deteriorates.

Observe yourself. Perhaps your chronic fatigue and lethargy is treated with two or three extra glasses of water. Lack of fluid can cause joint and back pain. I recommend it to drink more water for smokers and alcohol lovers. Alcohol is the only drink that does not quench thirst, but on the contrary, removes fluid from the body.

We can compare the hangover to the condition of a person who spent a day in the desert without water. Diet ologists have different opinions about coffee and tea. Some believe that coffee and tea remove water from the body. Others say that there is no principal difference, but it is better to quench your thirst with water.

There are no universal recipes - how much water to drink per day. Drinking regime depends on health, nutrition, motor activity and environment. The best way to avoid dehydration for a healthy person is to listen to your body and drink clean water.
