What happens to your body if you don't drink enough water

75 percent of our brain is water. When dehydrated, the brain shrinks, but how does this affect its function?

Based on some urine samples taken from children between the ages of 9 and 11 in Los Angeles and Manhattan, almost two thirds of them went to school almost dehydrated, which could negatively affect their teaching performance.

If you take two groups of kids and you tell them before one test to drink one glass of water and none of them, you can guess which group gets better?

The researchers concluded that these results show that even children in a mild dehydration state can benefit from greater water drinking and improve their continative performance.

Hydraming can also affect your mood. Limitation of fluid consumption increases drowsiness and fatigue, lowers energy levels and vigilance, and increases the feeling of confusion.

But once these students are allowed to drink water, vigilance, happiness, and clarity return almost immediately.

The absorption of water is immediately done in five minutes, from mouth to bloodstream, reaching a peak in the twentieth minute. Interestingly, cold water is absorbed about 20 percent faster than water at an environmental temperature.

How do you know you're dehydrated?

Just check your body “If you drink water and urinate in a short time, that is a sign of the body that has been fed. But if you drink some water and the body keeps much of it, this indicates that your reserves are running out.

Researchers used this concept to develop a formal tool for dehydranation: Empty your bladder, drink three glasses of water, and after an hour see how much you will urinate.

They decided that if you drink three glasses of water and, within an hour, urinate less than one drink, you were likely dehydrated. /Periscopi/
