Many experts have said that much of the human body is water. In fact the body is made of approximately 60% water. But not all the water stays there. Part of it is excreted in the urine, sweat and even when we breathe. So drink enough water to cover these losses is critical. But what happens when we do not drink enough?

'Seat of the Centre'

"The water is a universal solvent, provides nutrients to the body, regulates body temperature and lubricates the eyes and joints," said Mitchell Moffit and Greggory Brown, the AsapSCIENCE, a YouTube channel specializing in science. Without water we lose energy, the skin becomes dry and even the mood is affected.

The educator Mia Nacamulli explains in an animation released in a TED-Ed conference focused on education, that when the body dehydrates the nerve endings of the hypothalamus of the brain - which are what scientists call a "thirst center" (OCPTL ) - send signals to the release of antidiuretic hormone.

This hormone reaches the kidney and stimulates the aquaporins, protein of cell membranes which can transport water molecules, allowing more blood to retain water in the body. When this occurs, urine is darker and stronger smell.

During this process of dehydration also feel less desire to urinate and have less saliva. There is also the possibility of feeling dizziness because the brain is trying to adapt to the lack of liquid.

Adaptation

A dehydrated brain shrinks due to lack of water and must work harder to achieve the same result as a brain well hydrated. Moreover, it also enables a number of adjustment mechanisms to be able to maintain its activity despite the lack of liquid.

In entando, this process can continue for a few days: if you completely stop water intake, the body will begin to suffer from the more serious effects and, in the end, will stop working.

Leave drinking water for days (chronic dehydration) can pave the way for other problems like diabetes, high cholesterol, skin problems and digestive, fatigue and constipation.

The survival time without water varies between three and five days, according to each person. But there have been cases of those who managed to survive longer.

How much per day?

The amount of water that must drink depends on the body each and the environment where one lives. But, according to educator Mia Nacamulli, the most recommendable is that men drink between 2.5 and 3.7 liters per day and women from 2 to 2.7 liters.

But it is also important not to exceed the amount needed: drinking too much water can bring health risks, according to experts. Researchers at the Faculty of Medicine at Harvard University, in the United States, revealed in 2015 that the recommended amount of water varies between four and six cups a day. Earlier it was reported that it took eight glasses of water a day.

According to scientists from Harvard, it is impossible to make a recommendation that fits all: the need for water consumption depends on the diet, climate and level of physical activity practiced by the person.

Pregnant women or mothers who are breastfeeding, people who do more physical activities, those living in a warm climate or those who are sick should, according to the US report, drink more water. And if you're the type who does not like water, can consume liquids otherwise: fruits and vegetables such as melon or cucumber have large amounts of water.

But doctors warn, can not substitute water for soda - "choose to drink water instead of sugary drinks." Therefore, an option presented by the American Control and Disease Prevention Center (CDC), is to add a lime wedge or lemon to add flavor to water.
