Drink water:
Drinking water is a way for organisms to absorb water through their mouths. The daily intake of liquid through the mouth is about 2 liters. Water is mainly absorbed in the stomach. After water enters the human body, it is mainly used to supplement intracellular fluid and extracellular fluid, and participate in various physiological activities of the human body. Therefore, drinking water is an important part of maintaining biological metabolism.
How to judge water shortage:
If you don't know whether to drink more or less water, here is a little trick, which can be judged according to the color of urine. Generally speaking, human urine is light yellow. If the color is too light, maybe they drink too much water. If the color is too dark, it means that more water is needed.
