Is it the coldest in 24 solar terms, severe cold or slight cold? What are the specific reasons?

Slight cold and severe cold have always been two solar terms that many people are very entangled in, because as long as it is winter, no matter which solar term is very cold, people will only feel the edge of their bodies, but they don't know which day is the coldest. So which solar term is the coldest, slight cold or severe cold?

Does the coldest day start with a chill or a slight chill?

The winters in south and north China are different. In mild cold season, it is often colder in the north, but in severe cold season, it is colder in the south.

The annual slight cold solar term starts from 65438+10.57, with a solar term of 15 days, and the middle section is just within the slight cold solar term. So for most parts of the north, slight cold is indeed colder than severe cold.

However, for most parts of the south, solar terms are the coldest in the great cold. The severe cold solar term generally starts from 65438+1October 20th, and the end of 65438+1October happens to be the coldest time of the year in the south.

During the slight cold season, most parts of our country entered a severe cold period, with frozen soil and rivers, cold air in the north constantly moving south and cold weather. People call it nine cold days. Although South China is not as cold as North China, the temperature will drop obviously. The coldest time in the south is two periods between slight cold and rain and fright.

How to keep warm in slight cold and severe cold?

1, warm feet

We all know that it is very important to keep your feet warm. Although your feet support the construction of the human body, they are far from the heart, and blood circulation is easily affected. Moreover, the subcutaneous fat layer is thin, the thermal insulation performance is poor and it is easy to catch cold. Therefore, we must pay attention to keeping shoes and socks warm and dry in winter; After sitting for 2~3 hours, you can get up and walk for 10 minutes to promote blood circulation in your feet. In addition, after soaking your feet with hot water before going to bed, massaging your feet with your palm for about 10 minutes can also play a health care role.

2. Warm head

Most of the human meridians converge on the head. If you don't protect your head, just like a thermos without a lid, the yang in your body is the easiest to dissipate. So it is very necessary to wear a suitable hat when going out in winter. The temperature is low in winter, so be careful when choosing hats, and keep warm, such as knitted hats, knitted hats, cotton hats or velvet hats, so as to better protect your ears and head.

Step 3: Warm neck

Neck joint, body follows trunk. It is a very important part of the human body. When the human neck catches cold, it may lead to local vasoconstriction, rapid reduction of blood, and even serious discomfort such as dizziness and insufficient blood supply to the brain. Therefore, when you go out in winter, you must prepare a warm scarf to resist the cold and prevent colds.

4. Warm knees

Old people must pay attention to keeping their knees warm in winter. In fact, this is reasonable. The knee joint has less fat and is easily stimulated by cold. Moreover, in winter, the blood supply around the knee joint will be reduced, and the protection ability and body adjustment ability will also be reduced. Cold air can easily invade people's bodies and easily induce knee pain. Therefore, for women, it is best not to wear short skirts and cropped trousers. In winter. When riding a bike or going out for exercise, you can wear knee pads and be careful not to exercise too much.
