"Spring covers and autumn freezes" is a folk health-preserving proverb in China. It is scientific to analyze it from the perspective of climatology.

Although spring and autumn are both transitional seasons, there are still differences. In China, March-May is usually called spring, and September-165438+1October is called autumn. The average maximum temperature in spring is higher than that in autumn; The average minimum temperature in autumn is higher than that in spring.

This shows that although the daytime temperature is higher in spring, it is still lower in the morning and evening. In addition, spring is a recovery period, and the indoor temperature does not rise as fast as that outside, so it is very hot outside in spring, but it is cooler when entering the room. On the other hand, autumn is a cool season. Although the outdoor temperature has dropped, the indoor temperature is still relatively warm.

Therefore, if you don't "cover" it in spring and take off your cotton-padded coat in case it gets hot, you may not be able to fully adapt to the temperature in the morning and evening and indoors. Therefore, I advise you not to take off your cotton-padded clothes too early and cover them for a while, which is beneficial to health care in spring. Autumn is "not cold". When it is cold, clothes are added, which is not suitable for indoor temperature. Because autumn has just turned cold and the cold days are still behind, it is also helpful to wear less clothes and improve the cold resistance and resistance.

In spring, cold air from the north will continue to invade China, and its frequency and intensity are higher than those in autumn. In order to adapt to frequent temperature changes and strong winds, clothes in spring are warmer than those in autumn.

* "Spring covers autumn and freezing" is a health-preserving proverb, which is the experience of people's health care. There is a certain scientific reason, which is more positive for infants with immature body systems.

"Spring covering" means that in spring, when the temperature is just getting warmer, don't take off your cotton-padded clothes too early, so that the heat generation and cooling regulation of your body are in a relatively balanced state with the environmental temperature in winter. From winter to early spring, it is warm and cold at first, and the temperature changes greatly. As the saying goes, "Spring covers your face three times a day." Take off your cotton-padded clothes too early. Once the temperature drops, a sudden attack on the baby's nervous system and thermoregulation center will make it unprepared and difficult to adapt, thus reducing the body's resistance. At the same time, germs multiply in spring, take advantage of it and invade the baby's body, which is easy to cause various respiratory diseases and infectious diseases in winter and spring.

"Autumn freezing" means that in autumn, when the temperature is slightly cold, don't put too many clothes on your baby too early. In hot summer, people's body temperature regulation center does everything possible to increase heat dissipation, reduce heat production and prevent heatstroke. In cool autumn, the thermoregulatory center can slow down, which is more acceptable to it and produces comfort. Proper cool stimulation helps to exercise the baby's cold tolerance, which is called "low temperature acclimatization". That is to say, in the environment where the temperature is gradually decreasing, after a certain period of exercise, the metabolism of substances in the body can be promoted, the heat production can be increased, and the adaptability to low temperature can be improved. Similarly; When the seasons begin to change, the temperature is often unstable, the autumn wind blows, and the summer heat has not subsided. Dress the baby too early. Once the temperature rises, it is easy to catch a cold and catch a cold.

Of course, there is a limit to everything. "Spring and autumn freeze" does not rule out changing clothes for your baby in time according to the weather changes. People's body temperature should always be kept at around 37℃, on the one hand, through self-regulation, and at the same time, through increasing or decreasing clothes to ensure. If the baby is still covered too much or too thin in the late spring and autumn, such "covering the spring and freezing the autumn" is too much. March and 1 1 month are the high incidence seasons of baby's respiratory diseases. This has a lot to do with the great change of temperature and improper adjustment of clothes.

According to the traditional concept of our country, we are always afraid of the baby freezing, not so afraid of covering it, thinking that the baby is delicate, has low cold resistance, loves to get sick with cold, and does not pay attention to actively enhancing the baby's cold resistance. In fact, the more you cover up, the more you like catching a cold and getting sick. Within a certain range, it is better to wear less than more.

Does it make sense to "cover the spring and freeze the autumn"

"Spring covers and autumn freezes" is a colloquial phrase we often hear. The weather has just warmed up in spring. Don't take off too many clothes at once, but cover them a little. In autumn, the weather has just turned cold. Don't wear too thick clothes too early, so your body will freeze a little. "Spring covers and autumn freezes, and all diseases are difficult to touch" is the experience that people have summed up in their long-term life practice. Therefore, this sentence has certain scientific truth.

We know that 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.

How does the human body maintain normal body temperature? First, the internal adjustment of the body, such as the expansion and contraction of blood vessels under the skin and more or less sweating, can adjust the heat dissipation of the human body; The second is to help by adding or subtracting clothes. Wear less clothes when the weather is hot. This is convenient for the body to dissipate heat. If the weather turns cold, put on more clothes to avoid losing too much heat.

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.

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.
