The weather is hot and the electric fan is blowing all the time. Why is my whole body feeling soft and sore?

Traditional Chinese medicine says it is a sign of qi deficiency. The weather is hot in summer and the pores are open. Sweating is the fluid of blood. Sweating consumes energy. If you blow a fan, because the pores are open, you will be susceptible to colds. Wind evil invades, and wind evil is the first of the six evils and is the most likely to cause disease. This is like riding an electric bike in summer, which is most likely to injure knee joints. Because summer is hot, the pores are open and are susceptible to wind; in winter, the temperature is low, and although it is cold, the pores are closed, making it less likely to be injured. Furthermore, when taking a hot bath, the large opening of pores is a process of dispersing and consuming gas. If you are weak or hungry, you will easily feel dizzy or even have difficulty breathing when taking a hot bath. However, when you get cold out of the bathroom, your pores will Immediately shut down, qi and blood are no longer consumed, blood vessels contract, and qi and blood are transported to the brain. The person becomes energetic immediately. The principle is the same. It is said that those who practice Neijiaquan must first practice skin training.

It operates, and people use it every day without knowing it. Small phenomena contain big principles. Chinese health-preserving techniques are summarized from these small principles. Hope this helps.
