Dehydration can occur not only with reduced water supply, but also with significant loss. Therefore, if a person does not provide water to the body, and in addition has diarrhea, fever, takes dehydrating drugs or suffers from diseases that increase urine secretion, he is more predisposed to dehydration.
Symptoms of dehydration depend on its degree. Initially, a person begins to feel intense thirst and lose weight. Then there is dry mouth, pain and dizziness, weakness, urinary retention, dark spots in the eyes, nausea, drop in blood pressure, rapid breathing and heart rate, dry mucous membranes, loss of skin elasticity, eye collapse.
Drowsiness, swelling, convulsions and disturbances of consciousness appear in severe dehydration. Untreated dehydration leads to death.

1.5 liters + 0.05 liters for every kg of body weight over 20 kg
It should be remembered that the demand for water depends not only on the body weight, but also on the lifestyle of the person. Athletes and people working in high temperatures should drink up to 4-5 liters of water a day.
