Is it scientific to cover spring and freeze autumn?

I think it makes scientific sense. In fact, the internal reason is to give the body a buffer period. Whether you are healthy or doing other things, it is the same, and you need a buffer period. A reasonable buffer period can often get twice the result with half the effort.

Let's talk about why "spring covers". Before spring, it is winter. In winter, everyone is wrapped up, and everyone is eager for the winter to pass quickly. In this case, the whole body will feel much more relaxed. But in spring, there will always be cold in spring, which I think everyone should know. If you don't pay attention to the cold at this time, it will easily lead to a cold. Every year, the spring is chilly, and there are still many people who catch a cold. So everyone must pay attention to keep warm. At present, spring is followed by summer. If you wear little in spring, how can you get used to it in summer? So spring is a transitional period connecting winter and summer.

Let's talk about "autumn freezing". Old people often tell us not to cover too tightly in autumn, but to adapt to summer slowly, which will be better for our health. Many people often have chapped skin in winter. Mainly because they are wrapped tightly in autumn, they can't adapt to the cold in winter quickly, so their skin will be chapped. For good skin in winter, don't cover too much in autumn, and freeze it properly to better adapt to winter. Generally speaking, "spring covers autumn and freezing" is still very scientific.
