What benefits does drinking water have to the body?

Water is the source of life, and 70% of the human body is made up of water. People can go without food for three days, but they cannot go without water for three days. Especially in hot weather, we should pay more attention to the daily drinking water. Drinking more water can help digestion. The food you eat is digested and absorbed from the esophagus to the gastrointestinal tract after chewing your teeth and wetting your saliva. The whole digestion process needs the participation of water to accelerate the dissolution of nutrients by body fluids.

Drinking more water is good for excreting waste. After the nutrition of food is digested and absorbed, the remaining residues are excreted by sweating, breathing and excretion, which all need the help of water. Drinking water can balance body temperature. When the ambient temperature is lower than the body temperature, in order to maintain the body temperature and normal physiological activities, the water in the body will remain in the body because of the reduced evaporation of the narrowed pores. If the ambient temperature is too high, water will be discharged from the body through the dilated capillaries, and the body temperature will drop.
