In spring, the yang between heaven and earth and human body gradually rises, showing a changing state. However, don't think that you can completely take off your heavy clothes and go into battle lightly at this time, because although the weather is getting warmer, the cold is still very heavy, and the human body's yang has not recovered immediately, which belongs to the state of "Yang does not flourish and Yin does not retreat", so the cold resistance is still insufficient. So suddenly take off your warm clothes at this time, coupled with the sudden drop of temperature in spring, it is easy to catch a cold, and then there will be colds, coughs and colds.
If the temperature hasn't dropped in autumn, putting on thick clothes too early is actually against the laws of nature and human function, and can't enhance the body's cold resistance. Add clothes gradually in autumn, and add clothes appropriately according to the temperature. When the weather is just cold, clothes should be added to the extent that they can withstand the cold. Don't feel warm and wear thick clothes too early. Also pay attention to exercise. Proper exercise helps to improve the body's cold tolerance and enhance immunity, but after the temperature drops significantly, we should increase clothes to prevent diseases.
Don't put on too many clothes too early. Proper cool stimulation is helpful to exercise cold tolerance. After a certain period of exercise in the environment with gradually decreasing temperature, it can promote the metabolism of the body, increase heat production and improve the adaptability to low temperature. By the same token, when the season begins to change, the temperature is still unstable and the summer heat has not subsided. Add too many clothes too early. Once the temperature rises, it is easy to catch a cold and catch a cold.
