In general, our body generates heat continuously, and when its temperature exceeds a certain threshold, include mechanisms that protect it from overheating, and we begin to sweat.

Liquid released by sweat glands, consists mostly of water, a certain amount of organic compounds and mineral salts. Therefore, if we dwell for long in the sun, you should drink plenty of fluids to replenish its damage in the body.

"Most of us drink only one third of the required amount of water - says Galina Kholmogorova, Senior Research Fellow State Research Center for Preventive Medicine. - The minimum necessary to maintain normal water balance in the body, makes 1,5 liters at an average air temperature of 21 degrees, 1.9 liter - at a temperature of 26 degrees and 3 liters - at a temperature of 32 degrees.

These include liters water, juices, soups, and "hidden" fluid fruits and vegetables. Water not only comes into our body from the outside, but is formed during digestion. 100 grams of fat, for example, give the oxidation of 107 g water, 100 grams of carbohydrates or protein - respectively 35 and 1941

In principle, the drinking regime is determined by age, health, nutrition, weight of the work performed, the ambient temperature. For example, when working in hot shops in the sweat may be eligible for up to 4 liters of water per hour, so that should compensate for the loss of the appropriate amount of liquid.

Even without the hard work of human water consumption is quite large: in the urine for around 1.5 liters, the evaporation through the skin up to 1 liter or more, about 300 ml - with breathing and approximately 200 ml - with the feces. As a result, about 3 liters.

However, force yourself to drink when you do not want is not: an excessive amount of water increases the pressure on all bodies, especially on the kidneys and heart.

In addition, the more you drink, the more sweat, the more you want to drink - a vicious circle. Leachables with salt and then violate the usual content of microelements in the organism that can cause weakness, dizziness, heart palpitations.

Limit itself to the need to drink during pregnancy, hypertension, heart failure, impaired renal function.

Now that doctors recommend to drink, and what does not matter how hot you were not.

Too chilled liquid water deficit is not filled. They are staying longer in the stomach, and they contain mineral salts for a long time do not enter the cells of the body. In addition, the cold fluid stimulate the sweat glands. It is best to drink a liquid at room temperature.

Hot green tea without sugar is best thirst quencher. You can replace it with a mint drink still mineral water, black tea, kvas, homemade compote of dried fruits or fruit drink. Good natural unsweetened juices (apple, orange, grapefruit).

Lemon juice diluted with water in a ratio of 1:10, restores the electrolyte balance of the body and inhibits excessive sweating. You can drink mineral water instead of 2.5 liters per day and is due to vitamin C, will weaken the consequences of such heat, as fatigue, headache, lethargy.

m sweet drinks in the heat would have to give. It will quench the thirst not, because it contains sugar. So, you drink a liter or two of receiving, so a lot of unwanted calories, which were then put off in excess zhirok.

You should not get involved in beverages containing caffeine - he, as well as alcohol accelerates dehydration. The only thing that you can afford from alcoholic beverages - a dry white or red wine diluted with water in a ratio of 1:3, with an ice cube.

And finally, if you can not live without beer, it is advisable to drink only light - not stronger than 4.5 degrees. Just keep in mind that "razvezet" you are much more likely than usual weather.

If for some reasons related to chronic diseases, you should restrict the flow of fluid in the body, well always have on hand spray with plain water from time to time to rinse your mouth, spray on bend of the elbow, knees, wrists.
