“Spring cover autumn freeze, miscellaneous diseases difficult to birth” is a health care disease prevention proverb, which means that people are advised not to rush to take off cotton clothes in the spring, and do not just see cold in the fall to wear too much, appropriate cover a little or freeze a little, for the health of the body is good. Spring cover that: spring temperature just turned warm, do not take off cotton clothes too early. After wearing cotton clothes for several months in winter, the body’s regulation of heat production and heat dissipation is in relative balance with the ambient temperature in winter. From winter to early spring, the first warmth, temperature changes and big, prematurely take off the cotton clothes, once the temperature drops, it will be difficult to adapt, so that the body resistance to decline. Germs take advantage of the situation and easily cause various respiratory diseases and infectious diseases in winter and spring. Autumn freeze that: autumn temperature is slightly cooler, do not add too much clothing too early. Suitable cool stimulation, help exercise cold tolerance, in gradually lowering the temperature of the environment, after a certain period of exercise, can promote the body’s metabolism, increase heat production, improve the resilience to low temperatures. By the same token, when the seasons have just begun to change, the temperature is still unstable, the heat has not yet receded, too much prematurely increased clothing, once the temperature rises, sweat and wind, it is easy to catch a cold. Scientific reasoning We know that summer to autumn, from hot to cold transition phase, the weather is cold, but there is a process of transformation. Through the appropriate “autumn freeze”, so that the body slowly adapt to the gradual decline in temperature, so as to prepare for the upcoming cold winter months. The “autumn freeze” can invariably improve one’s physical fitness. On the other hand, in Chinese medicine theory, autumn is the season to nourish Yin, if you wear too much, it will encourage Yang Qi, which is not good for the body. If you put on cotton clothes too early, you will not get the body to exercise against cold air, so that the ability to prevent cold is reduced, which is not conducive to the regulation of human body functions. As a result, when the cold season comes, once the nose and trachea are attacked by cold air, the blood vessels inside cannot resist and contract, which reduces blood flow and causes a weakened antibacterial ability, and the germs hiding in the nose or trachea take the opportunity to move, causing coughing, sneezing This can cause coughing, sneezing, runny nose, fever, and colds. Therefore, in autumn, you should freeze first, and clothes should be increased slowly. There are degrees of everything, too much is a disaster Autumn freezing is to improve people’s tolerance to the gradually cold environment, but if the individual’s physique is already weak, it is best not to freeze indiscriminately. People’s body temperature is always to maintain a constant temperature, on the one hand, by their own regulation, but also by increasing or decreasing clothing to assist, if the late spring and late autumn, still cover a lot or wear too thin, so the “spring cover autumn freezing” is too much, every year in March and November is the high incidence of respiratory disease season, on the one hand, the temperature changes, and at the same time with the clothing The season of March and November each year is a high incidence of respiratory diseases, on the one hand, the temperature changes, and at the same time, with improper adaptation of clothing also has a great relationship. It is worth mentioning that even for the healthy people, “spring cover and autumn freeze” is also conditional. In general, when the sunshine temperature is 15℃-20℃, people can reduce their clothing, but when it is really close to early winter, this principle is no longer applicable. Blindly “autumn freezing”, do not take. Autumn freezing is not suitable for everyone The elderly, frail people, children, cardiovascular and cerebrovascular disease patients, chronic kidney disease patients, gastric and duodenal ulcer patients, etc. should not “freeze”, that is, healthy people must also pay attention to “freezing” moderate. Autumn is also a time of high incidence of cardiovascular diseases. For middle-aged and elderly people with a history of this disease, it is especially important to prevent cold. If this part of the population ignore the actual situation, boldly try “autumn freezing”, it will be a very dangerous move. For example, although wearing slippers is more fashionable and comfortable, but the rhythm of the peripheral circulation is disrupted, easily triggering symptoms such as increased blood pressure. Temperature fluctuations, the weaker people should pay particular attention to protect the head, hands, feet these three key parts.
