When thirsty, many people are used to gulping water. As we all know, this way of drinking water is not good for your health. Small amount, multiple times and slow drinking are three basic principles.
There are three possible consequences of gulping water:
First, drinking a lot of water at one time will quickly dilute the blood and increase the burden on the heart. After the exercise, this situation became more serious.
Secondly, when sweating heavily in hot days, overeating will increase the amount of perspiration reflexively, further increasing the loss of electrolytes such as sodium and potassium, so people tend to drink more and more thirsty.
Third, drinking too fast and too hard will swallow a lot of air together, which is easy to cause hiccups or bloating.
A reasonable way to drink water is to put a mouthful of water in your mouth and slowly swallow it several times, which can fully moisten your mouth and throat and effectively relieve your thirst.

Physiological function of water
1. Help digestion: The food we eat in our mouth is digested and absorbed through the digestive process from esophagus to gastrointestinal tract after being chewed by teeth and wetted by saliva. All these links need water to participate, which accelerates the dissolution of nutrients by body fluids.
2. Waste excretion: the residual waste after digestion and absorption of food nutrition should be excreted through sweating, breathing and excretion. These different ways of excretion need the help of water.
3. Lubrication of joints: Human joints need lubricating fluid to avoid damaging the friction between bones, and water is the main source of joint lubricating fluid.
4. Balance the body temperature: When the ambient temperature is lower than the body temperature, in order to maintain the body temperature and ensure normal physiological activities, the water in the body will remain in the body due to the reduced evaporation of the narrowed pores; When the ambient temperature is higher than the body temperature, water will be discharged from the body through the expanded capillary breathing hole, which will lower the body temperature. The body ensures its survival function through the dispersion of water.
5. Maintain cells: water can promote cell metabolism and maintain the normal shape of cells; Keep skin moist and elastic.
6. Balance blood: Water can improve the circulation of blood and tissue fluid and help balance the viscosity and pH of blood.
