"Summer heat is easy to hurt qi". Summer heat can make people sweat too much, make people dizzy, chest tightness, palpitation, thirst, nausea and even coma. Therefore, when arranging labor or physical exercise, we should avoid the scorching sun and pay attention to strengthening protection.

Living and working in winter, the idea of TCM health preservation, such as "Su Wen Si Qi Tiao Shen", says: "In winter and March, this is closed storage. Water and ice are frozen, without the interference of the sun; Get up early and go to bed late, and wait for the sun. ..... When the cold dissipates, it will warm up, and there will be no skin leakage, so the gas will be caught. This winter air should be the way to raise Tibet. " "Thousands of Women: Cultivating Nature in Daolin" also said: "In winter, the world is closed and blood is stored, so people should not sweat and vent yang, which is harmful to people. "In the cold winter, don't disturb the sun be the spirit, to destroy the physiological proportion of Yin forming and Yang forming. Therefore, it is necessary to go to bed early and get up late, and do it at sunrise to ensure adequate sleep time, which is conducive to the accumulation of hidden yang and yin essence. As for cold and warmth, it must also be properly kept in accordance with the principle of "not disturbing the sun". Too few clothes are too thin, and the room temperature is too low, which not only consumes yang, but also easily catches a cold. On the other hand, if the clothes are too thick and the room temperature is too high, the yang will not be hidden, and the cold evil will easily invade. " Su Wen's "Golden Chamber and Strict Array" said: "The husband's essence is also the foundation of the body, so it is hidden in the essence, and spring is not sick but warm. "It shows that it is of great significance to control sexual intercourse in winter and nourish and preserve semen in spring to prevent fever.
