Generally speaking, adults with mild climate and light physical activity drink 1500 ~ 1700 ml (about 7 ~ 8 cups) every day. People who work or exercise in a high temperature environment have a high level of physical activity and sweat a lot, so they need to increase their daily water consumption according to their own specific conditions.

Even in the general ambient temperature, athletes, farmers, soldiers, miners, construction workers, firefighters and other people still have a lot of physical labor in their daily work, which will increase the loss of water due to sweating. Pay attention to supplementing water and consider supplementing salt.

Scientific drinking water method

Pay attention to scientific methods in drinking water. First, a small number of times. About 200ml each time (1 cup). When the water in the body reaches balance, it can ensure that the digestive juice is fully secreted during meals, stimulate appetite and help digestion. Drinking plenty of water at one time will increase the burden of gastrointestinal tract and dilute gastric juice, which will not only reduce the bactericidal effect of gastric acid, but also hinder the digestion of food. Secondly, we should supplement it in time. Drink water at any time of the day, and you can drink it at any time. Never drink water when you feel thirsty.

Drinking a glass of water on an empty stomach after getting up in the morning can reduce blood viscosity and increase circulating blood volume. Drinking a glass of water before going to bed is beneficial to prevent the blood viscosity from increasing at night. Exercise accelerates the loss of water in the body and needs to be replenished in time. Boiled water is the first choice when replenishing water. Cheap, safe, hygienic and healthy are the biggest advantages of boiled water. Compared with sweet drinks, boiled water can avoid the risk of obesity and dental caries caused by high sugar.
