First, it varies from person to person.
There is an old saying in China, "Dressing in disorder in February and August", which means that in February and August of the lunar calendar, people's clothes and dressing are prone to "disorderly collocation", while in the solar calendar, these two periods are also the time when winter and spring change seasons and summer and autumn change seasons.
Among the "disorderly wearing" ethnic groups, some follow the body feeling, while others advocate "covering spring and freezing autumn". The latter emphasizes that people's physique will become stronger and stronger after experiencing "autumn freezing", but the expert's view is that "freezing in spring and autumn" will vary from person to person. Autumn freezing is to improve people's tolerance to the gradually cold environment, but if the individual's physique is weak, it is best not to freeze. The so-called "freezing in spring and freezing in autumn" means that through appropriate "freezing in autumn", the human body can slowly adapt to the gradually decreasing temperature and prepare for the coming winter. Just like 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 of nourishing yin. Wearing too much will encourage yang, which is not good for your health.
It is freezing in autumn, and autumn is the high incidence period of cardiovascular and cerebrovascular diseases. For middle-aged and elderly people with this medical history, cold protection is particularly important. Experts said that it would be very dangerous for this group of people to try to "cover the spring and freeze the autumn". For example, although wearing slippers is fashionable and comfortable, the rhythm of peripheral circulation is disrupted, which is easy to cause symptoms such as elevated blood pressure. People with large temperature fluctuations and weak constitution should pay special attention to protecting the three key parts: head, hands and feet.
It is worth mentioning that even for healthy people, "covering the spring and freezing the autumn" is conditional. In general, when the sunshine temperature is 15℃-20℃, people can reduce their clothes appropriately, but this principle is no longer applicable when it is really close to early winter. It is definitely not advisable to blindly "freeze in autumn".
Second, spring covers autumn and freezing.
"Spring covers and autumn freezes" is a health-preserving proverb, which is people's health-preserving experience and has certain scientific truth. "Spring cover" refers to spring, and the temperature has just warmed up. Don't take off your cotton-padded clothes too early. After wearing cotton-padded clothes for several months in winter, the regulation of body heat production and radiation is in a relatively balanced state with the environmental temperature in winter. From winter to early spring, it is warm and cold, and the temperature changes greatly. As the saying goes, "In spring, a child's face changes three times a day". Once the temperature drops, it will be difficult to adapt and the body's resistance will drop. Bacteria attack the body, which is easy to cause various respiratory diseases and infectious diseases in winter and spring.
Third, scientific truth.
"Covering in spring and freezing in autumn will not cause miscellaneous diseases" is a proverb for health care and disease prevention, which means to advise people not to take off their cotton-padded clothes in spring and not to wear too much when they are cold in autumn. Proper covering or freezing is good for their health.
People's body temperature is always relatively constant, generally around 37℃. If the body temperature is too high or too low, it will damage the physiological function of the human body.
1, spring cover
Winter goes and spring comes, which is a transitional stage from cold to hot. Although the weather is getting warmer, the climate often changes, sometimes warm and sometimes cold. Often after the sun comes out, it will be warm and sunny, and it will be cold when it is windy and rainy. Because people are used to wearing more clothes in winter, if they take off too much in spring, they will not adapt to climate change and get sick easily. Therefore, in the early spring, you should deliberately cover a little and slowly reduce your clothes.
In spring, the temperature of nature is rising, but the indoor temperature can't keep up with the outdoor because of the thermal inertia of the house, resulting in the temperature difference between indoor and outdoor. This temperature difference reaches its maximum in the sunny afternoon of a day, often as high as 3-5℃ or even more. Especially when walking into a cool room from the warm sunshine, the elderly and patients must put on clothes and spring clothes to avoid catching cold and getting sick. Because the temperature rises (falls) fastest in spring (autumn) in China at the same latitude, the unique health-keeping proverb "Spring covers and autumn freezes" in China was born.
Step 2 freeze in autumn
Going to Qiu Lai in summer is a transitional stage from hot to cold. Although the weather is getting cold, there is a process of transformation. Some people wear a lot of clothes in autumn, and even put on cotton-padded clothes too early. This is not good, because putting on cotton-padded clothes too early will make the body unable to exercise cold air, reduce the cold-proof ability, and is not conducive to the adjustment of human functions. In this way, when the nose and trachea are attacked by cold air, the blood vessels inside can't resist and contract, which will reduce the blood flow and weaken the antibacterial ability and hide in the nose. Therefore, it should be frozen again in autumn, and clothes should be added slowly.
When the temperature drops in autumn, the indoor temperature lags behind the outdoor nature due to the thermal inertia of the house, resulting in an opposite temperature difference. Walking from outdoor to indoor, the temperature rises, so it is natural to take off your clothes to prevent freezing in autumn, so as to prevent sweating from hurting the yang and affecting your health.
Fourthly, we should pay attention to
There is an old saying in China, "Spring covers the autumn", but do you know where to cover it? According to experts, the blood circulation in the lower half of the human body is worse than that in the upper half, and it is easily attacked by cold, so the cold is from the bottom up. Therefore, dressing in spring should pay attention to "coarse and fine".
In hot and cold March, the temperature becomes faster and people's clothes become faster. It's getting hotter and hotter in recent days. Many fashionable women have taken off their heavy winter clothes, put on gorgeous spring clothes and even put on sandals. The author learned from the hospital that clothes should be changed slowly in spring, and cutting clothes too early is harmful to the health.
According to doctors, in recent years, there are more and more cases of knee joint diseases, and most of them are women. Many women have the habit of wearing skirts in winter and changing into spring clothes too early in spring, especially the "ladybug" with bare feet, which is the main way for cold to invade the body, and catching cold is the main inducing factor for diseases such as joint diseases. Because the blood circulation of the lower half of the human body is usually worse than that of the upper half, it is vulnerable to cold, that is, "cold self-sufficiency." If you don't pay attention to keeping warm in spring, you will cut down your clothes as soon as it gets hot. If you are not careful, you will catch a cold and have a fever. You may even have knee pain when you get old, and it will gradually develop into knee hyperosteogeny. In severe cases, there will be hydrops, swelling and inability to straighten the knee joint.
Doctors especially remind young women that early spring is warm and cold, the temperature difference between day and night is large, and cold air often invades. Therefore, you must not reduce your clothes too early, let alone put on sandals to show off your feet. It is good for your health to cover them for a few more days.
Autumn freezing is not suitable for everyone, including the elderly, children, patients with cardiovascular and cerebrovascular diseases, patients with chronic kidney disease and patients with gastric and duodenal ulcers. Healthy people must also pay attention to moderate "freezing".
