1, avoid cold at night, drink tea on an empty stomach, and the night is short in summer. Be careful not to eat cold and sticky things at night, otherwise abdominal distension, vomiting and diarrhea will occur. Drinking too much tea, especially on an empty stomach, can easily lead to consumption of yang. Therefore, drinking tea in summer should be two or three cups after meals, and stop drinking immediately when you are hungry.

2, avoid cold water bathing, cold water bathing is a favorite way for many people to cool off, but the weather is hot in summer, and people's pores and muscles are in a state of venting. Therefore, cold air can easily invade the human body, leading to the loss of yang. There will be symptoms such as cold hands and feet, calf cramps, blurred vision, and even unexplained fever.

3, avoid lying cold at night, Chinese medicine believes that "the head is the meeting of the sun", the head is the gathering place of the human body's yang, and lying cold at night easily leads to the loss of yang. So pay special attention not to sleep at night and don't turn on the air conditioner all night. This habit can easily lead to colds, facial paralysis, joint pain, abdominal pain and diarrhea, which is very serious to the body.
