The meaning of spring cover and autumn freeze: correct understanding
"Autumn freezing" means that the autumn temperature is slightly cooler, do not add too many clothes too early, appropriate cool stimulation will help to exercise cold resistance, in a gradually lowering temperature environment, after a certain period of exercise, can promote the body's material metabolism, increase heat production, improve the adaptability to low temperature.
In the same way, when the seasons first change, the temperature is still unstable, and the heat has not yet subsided. If you add too many clothes too early, once the temperature rises, you will sweat and catch a cold easily. Of course, everything has a degree, and "spring and autumn freeze" does not rule out changing according to the temperature.
People's body temperature always needs to be maintained at about 37 degrees Celsius. On the one hand, it depends on self-regulation, and at the same time, it also depends on adding or removing clothes to assist. If you still cover a lot or wear too thin in late spring and late autumn, such "spring and autumn freezing" is too much. March and November are the high-incidence seasons for respiratory diseases every year. On the one hand, the temperature changes greatly, and at the same time, it has a lot to do with improper clothing adjustment. There is no difference between the upper and lower bodies, the key lies in whether the whole body is coordinated.
"Cover in spring and freeze in autumn, do not produce miscellaneous diseases" is a health and disease prevention proverb, which means to advise people not to rush to take off cotton-padded clothes in spring, and not to wear too much when they see cold in autumn. It is good for the health of the body to cover a little or freeze a little. Human body temperature is always relatively constant, generally around 37 degrees Celsius. If the body temperature is too high or too low, it will damage the physiological functions of the human body.
Winter goes to spring, which is a transition from cold to hot. Although the weather has warmed up, the climate often changes, and it gets warmer and colder. Often after the sun comes out, the wind is warm and the sun is warm, and it will get colder when it is windy and rainy. Because people are used to wearing more clothes in winter, if they take off too much clothes in spring, they will not adapt to climate change and will easily catch a cold and get sick. Therefore, people should deliberately cover a little in early spring and slowly reduce their clothes.
In spring, the temperature in nature is in the rising stage, but the indoor temperature cannot keep up with the outdoor due to the thermal inertia of the house, resulting in a temperature difference between the inside and outside. This temperature difference reaches its maximum in the afternoon of the sunny day, often as much as 3-5 ° C, or even much larger. In particular, when entering a cool room from the warm sun, the elderly and the sick must add clothes and cover them in spring to avoid getting cold and causing illness. Since the temperature rises (falls) most rapidly in the spring (autumn) season at the same latitude in China, the special Chinese health proverb "spring cover and autumn freeze" was born.
Summer goes to autumn, which is a transition stage from hot to cold. Although the weather is cold, there is a process of transformation. Some people quickly put on a lot of clothes as soon as autumn arrives, and even put on cotton-padded clothes too early. This practice is not good, because putting on cotton-padded clothes too early will prevent the body from exercising against cold air, reduce the ability to prevent cold, and is not conducive to the regulation of human body functions. As a result, in the cold season, once the nose and trachea are invaded by cold air, the blood vessels inside cannot resist and contract, causing the blood flow to decrease, causing the antibacterial ability to weaken, and the bacteria hiding in the nose or trachea take the opportunity to move, causing coughing and spraying
After the spring warmth, you should change your spring clothes, sneeze, runny nose, fever, and make people catch cold and cold. Therefore, you should freeze again in autumn, and your clothes should be slowly increased. In autumn, the temperature is in the falling stage, and the indoor temperature lags behind the outdoor nature due to the thermal inertia of the house, resulting in the opposite temperature difference. When you enter the room from the outside, the temperature rises, and you naturally need to undress and "freeze" in autumn to prevent sweating and damaging the sun and affecting your health.
There is a saying in China that "dress indiscriminately in February and August" refers to the phenomenon of "chaotic matching" in people's clothing during February and August of the lunar calendar. On the Gregorian calendar, these two periods are also the time when winter and spring change seasons and summer and autumn change seasons. Some people in the "dress indiscriminately" group follow their body feelings, and others advocate "spring covering autumn freezing". The latter emphasizes that through "autumn freezing", people's physique will become stronger and stronger. However, the opinion of experts is that "spring covering autumn freezing" should your mileage may vary.
Autumn freezing is to improve people's tolerance to the gradually cooling environment, but if an individual's physique is already weak, it is best not to freeze indiscriminately. The so-called "spring covering autumn freezing" means that through appropriate "autumn freezing", the human body can slowly adapt to the gradually falling temperature, so as to prepare for the upcoming cold winter and twelfth lunar month. Just like a subtle exercise, "autumn freezing" can improve people's physique invisibly. On the other hand, in the theory of traditional Chinese medicine, autumn is the season to nourish yin. If you wear too much, it will encourage yang qi and be detrimental to the body.
Autumn freezing is also a time of high incidence of cardiovascular and cerebrovascular diseases in autumn. For the elderly with a history of this disease, cold protection is especially important. Experts say that if this group of people also try to "cover the spring and autumn freezing", it will be a very dangerous move.
For example, although wearing slippers is more fashionable and comfortable, the rhythm of the peripheral circulation is disrupted, which can easily lead to symptoms such as increased blood pressure. The temperature fluctuates greatly, and people with weak constitution should especially pay attention to protecting the three key parts of the head, hands and feet. It is worth mentioning that even for people with healthy physique, "spring and autumn freezing" is also conditional. Under normal circumstances, when the sunshine temperature is 15 ° C -20 ° C, people can appropriately reduce their clothing, but when it is close to early winter, this principle is no longer applicable. Blind "autumn freezing" is not advisable.
