What do people drink when they are thirsty, and why are people thirsty?

When the mouth is thirsty, the subconscious mind thinks of drinking water.

It's better to drink urine and add some sugar!

Because most of the components of the human body are water, that is, bodily fluids. Human body fluids can make all the metabolism of our body give the environment, people will urinate, will sweat, will naturally evaporate water, so people must drink water to maintain salinity balance, if you do not drink water, the salinity will rise, you will be thirsty.

physiologically. It's a very complicated process. I'm more direct to the cause:

Hunger: All human movement energy is produced by oxygen and glucose in the blood, which are fed into every organ for a reaction that produces heat as well as carbon dioxide and water, as well as amino acids and other indigestible things. If there is no oxygen and glucose, we will have no energy, we will be unconscious, unable to walk, dizzy, which is what we commonly call hunger dizziness.

Food, organic matter, especially sugar, chemical cho, after digestion to produce CO2, breath out, H2O will urinate. In addition, when we eat vegetables, there will be indigestion of fiber, which will take away a lot of indigestible impurities and bacterial debris, and excrete it as stool. It is worth mentioning that when we eat meat and eggs, it is actually protein, the chemical formula CHNO, and after digestion, it will produce HN, which is ammonia and urea, that is, fart and urine smell.

So food is energy-based. If you don't have energy, you'll be hungry.

Thirst: Because most of the ingredients in the human compound are water, that is, bodily fluids. Human body fluids are able to give all of our body's metabolism to the environment, including temperature and salinity.

If the temperature is too high, the active enzymes in the body will not be active, and all our resistance will be reduced, and we will be dizzy, which is what we often call fever; If the salinity is too high, it will slow down our fluid transport and metabolism, and our urine will turn yellow and our lips will be chapped and chapped. That's why it's about absorbing moisture. Because people urinate, sweat, and evaporate water naturally, they must drink water to maintain a balance of salinity.

If you don't drink water, the salinity rises, and you get thirsty. Therefore, when the weather is hot, sweating a lot, and eating a lot of salt, it is easy to be thirsty, and you need to absorb water and drink more water.

Most of the body is water, water is the source of life, the body is a system of its own, and there is a chain reaction when water is needed.

The most sensitive and direct thing is the command that the brain gives to the mouth.

As a result, people are thirsty when they lack water.

Every part of the body needs water for metabolism, and if there is no water in the body, you will be thirsty.

Finish. The reflection of water deficiency is thirst, and normal people generally need to replenish 1500 ml of water every day.
