What does autumn freezing mean?

Autumn freezing refers to the cold climate phenomenon brought by the first frost and snow in autumn.

Autumn freezing generally appears in the middle and late September to early June 10, which is one of the important signs of autumn in most parts of China. Autumn freezing was also called "first frost" in ancient times, which means that chill has gradually entered people's lives.

As the saying goes, "It's freezing in spring and freezing in autumn, so you don't get sick", which means don't take off your thick clothes in spring, and don't wear too many clothes when it's cold in autumn. Cover it or freeze it properly, which is good for your health. From the perspective of traditional Chinese medicine, winter belongs to the season of "water and ice", with yang lurking and yin exuberant. In spring, the yang of the human body is gradually rising, which is a changing state.

There is a folk proverb called "White dew does not show, cold dew does not show", that is to say, after the solar term of White dew, we should pay attention to keep warm and keep out the cold, so we don't have to stick to "autumn freezing" any more. At this time, you can't be naked, you can't be greedy for cold, you should pay attention to keep warm, so as to avoid the cold invading the human body and damaging the yang.

Autumn freezing often causes a certain degree of crop yield reduction, and also has a certain impact on people's lives. For crops, autumn freezing has a great influence on crops planted early, such as wheat, corn and rice. For crops planted late and moved late, autumn freezing has little effect on them, such as peanuts, sugarcane and pumpkins.

Take your time, undress in spring and dress in autumn-don't react too quickly to obvious changes.

It is not difficult to cover spring and freeze autumn. There is a big temperature difference between the north and the south, and there are also differences in personal physique, so we can't generalize. People with weak constitution, weak resistance and cardiovascular or respiratory diseases are not suitable for autumn freezing.

People's old legs fail first, and the yang in the lower body is weaker than that in the upper body. Try to keep warm. When it is frozen in autumn, generally wear less clothes on your upper body and don't freeze your legs. When the ambient temperature is continuously lower than 18℃, it is necessary to keep warm.

It is worth mentioning that even for healthy people, "spring covers autumn and freezing" 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. Blind freezing in autumn is not advisable.
