Professional doctors pointed out that it is too exaggerated and there is no scientific theoretical support to expel the accumulated cold in the body only by drinking hot water. Dog days are the hottest days of the year, with the most sunshine. Eating cold food and drinking cold drinks at this time is easy to hurt the qi of the sun, especially those with weak spleen and stomach, which is easy to aggravate the symptoms of physical weakness.
It is impossible to drive the cold out of the body in just a few days by drinking hot water in dog days. People sweat a lot in summer, so regular hydration can replenish lost body fluids, as long as you drink warm water properly in your daily life.
On the temperature of drinking water, it is suggested that the temperature should not be too high. Drinking hot water for a long time will burn oral and esophageal mucosa, cause stomatitis and esophagitis, and lead to local mucosal congestion and edema. It is suggested that the water temperature should be 40℃-45℃, and the oral temperature and gastrointestinal temperature are suitable.
According to the doctor, the dog days are the most vigorous stage of human yang. At this time, in order to adapt to the weather, the human body is in a state of "excess of yang and internal deficit". If you are too greedy, it will easily lead to excessive internal cold and make the yang in your body worse. So I suggest you drink less cold drinks.
The purpose of drinking hot water in dog days is mainly to perspire, that is, the function of sweating and relieving exterior syndrome in traditional Chinese medicine, which plays the role of dredging interior and clearing heat. However, this is just a way of keeping in good health. Although feasible, it will take a long time to persist. It is not just a short period of three volts that can eliminate the cold in the body.
Proper exercise and foot soaking and sweating can drive away the cold, but you have to persist for several years. In order to drive away the cold, you can usually eat less cold foods, such as snails, watermelons, persimmons, crabs, mussels, bamboo shoots, water chestnuts, white gourd, amaranth, cucumbers, lotus roots, soft-shelled turtles and mung beans. If you want to get rid of the cold in your body overnight, it is absolutely impossible.
