The first is the treatment of winter diseases in summer. Because the dog days are the hottest and sunniest stage in a year, at this stage, people's skin is slack, so it is easy for drugs to penetrate into acupoints and meridians from the skin, and they can directly reach the diseased parts through meridians and qi and blood, so treating winter diseases in summer can often achieve the best effect.

The second is to learn how to make up. There are "chickens on the head, dogs on the second floor, turtles on the third floor and red dates on the stomach" among the people. We must grasp the characteristics of dog days: high temperature, high humidity and relatively little sleep time. Tonifying should be combined with the actual situation of the individual, distinguish between the actual situation and the actual situation, and make up for the deficiency. 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.

Finally, it is necessary to "practice three volts in summer." 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 and high temperature weather, a kind of emergency protein will be produced in human body, which can resist the harm of summer heat to human body. This shows that the human body itself has the ability to adapt to different environments, and exercise in cold and summer can improve the body's ability to adapt to different environments.
