What is the meaning of TCM health preservation in summer?

The coming of the hot summer means that the hot summer has passed, the cool autumn has arrived, and the temperature has dropped in most parts of our country. At this time, the temperature difference between day and night is large. According to the constant change of temperature, clothes should be appropriately increased or decreased to avoid catching the flu!

Summer is the fourteenth solar term among the twenty-four solar terms and the second solar term in autumn. On August 23rd or 24th every year, the sun reaches 150 degrees. "almanac" said: "fighting refers to five, which is summer heat. Summer will retreat, squat and dive, hence the name. " "Twenty-four solar terms" said: "Go, go, the heat is over." "Out" means hiding and ending. Being in summer means that the hot summer is coming to an end, because the dog days are over or coming to an end.

There is a proverb that "summer solstice is cool" everywhere, and summer is the turning point of temperature drop. After summer, continuous autumn rains sometimes come early, so there is a saying that "an autumn rain is a cold".

At this time, although the temperature will still be high during the day, the temperature will be low in the morning and evening, and the temperature difference will be large. The public should guard against colds. The climate in autumn is changeable. After the hot summer, the internal friction of the human body is large, which leads to the decline of immunity. As the temperature gradually drops, viruses invade the human body with the help of respiratory diseases, especially in early autumn, and the temperature difference is obvious. Convective weather in the afternoon and large-scale cold air activities will lead to a sudden drop in temperature. Therefore, in summer, people should pay attention to increasing or decreasing clothes and beware of catching a cold.
