Drinking more water can relieve the working pressure of the kidney, make urination more smoothly, and prevent urinary tract infection. In addition, after water is absorbed by intestinal epithelial cells, it enters the blood and dilutes the toxin in the blood, which is discharged out of the body with urine.

Regulating body temperature

The specific heat of water is larger. Every 1 ℃ rise of 1G water needs 4.18j of heat, which is more than that of other liquids. The latent heat of evaporation is very large. When 1g water completely evaporates at 37 ℃, it needs 2204j of heat absorption, so a small amount of sweat can release a lot of heat. The heat produced in the process of human metabolism can also be sent to the surface of the body and distributed to the environment through blood, so as to maintain a balanced temperature in all parts of the body. Therefore, water plays an important role in maintaining the stability of body temperature.

Replenish water

When people have a cold and fever, the body will be out of self-protection function, a lot of sweating, shortness of breath, skin evaporation of water increase. When the water loss reaches 2% - 3% of the body weight, the patient will be thirsty and have less urine.

When water loss exceeds 20% of body weight, it can cause death.
