There are two principles for keeping in good health in dog days: one is to treat winter diseases in summer; The second is to make up in summer. As for the dog days, there are many ways to stay healthy.

There is a folk tradition of "chicken on the head, dog on the second floor, turtle on the third floor and red date belly on the third floor". Koreans also have the tradition of eating ginseng chicken soup, dog broth and other tonics in dog days. Xuzhou people say that "a bowl of soup for Pengcheng sheep doesn't need a prescription from a doctor", which shows that there is a custom of tonic in different areas in the dog days. In dog days, we must grasp the characteristics of dog days: high temperature, high humidity, long days and relatively little sleep time. Tonifying should be combined with the actual situation of the individual, and it is best to make tonic according to the symptoms under the guidance of a doctor. If you take supplements at will, it may increase the loss of the human body and add fuel to the fire. If you have respiratory diseases such as asthma and tracheitis, don't be greedy for cold food in dog days. People with deficiency-cold constitution should eat less cold food, such as pears, watermelons and cold drinks.

As the saying goes, "practice three or nine in winter and three volts in summer." This is a summary of the experience of long-term health preservation in ancient times. Modern medicine has proved that in hot weather, a kind of emergency protein will be produced in human body, which can resist the harm to human body in summer. It can be seen that the human body itself has the ability to adapt to different environments. Exercise in cold and summer can improve the body's ability to adapt to different environments. Therefore, the ancients believed that people who obtained health cultivation could "avoid cold and heat, and all kinds of poisons would not invade." However, to prevent heatstroke in summer, we should dialectically avoid the high temperature period. The doctor reminded that ordinary people should not advocate this kind of exercise, especially the elderly and infirm, or those who have lived in a suitable temperature environment for a long time and have low adaptability to different environments. Therefore, these people had better be in summer.
