Why is people s faces not afraid of cold, and why is it not cold in winter?

The capillary distribution of the human face is relatively rich, which makes the temperature of the surface of the face slightly higher than the rest of the body.

At the same time, since people's perception of heat and cold is relative, based on their own temperature, in this way, the human face will be conducive to resisting the cold, and compared with the rest of the body, it will not feel too cold.

The receptors of cold and heat sensation in the human body are structurally separate from nerve conduction. The face has about 8 9 "cold receptors" and a "thermal receptor" per square centimeter. The face is often exposed to cold air, and the "cold sensor" is excited, produces a cold sensation, conducts it to the central system, and through a series of regulatory activities, improves facial blood circulation and prevents frostbite.

Therefore, the face ** is more resistant to cold.

I don't think you know, or don't see, some people will freeze in the winter!

People's ** is exposed to low temperatures and cold winds, and it is easy for cold to invade. However, blood circulation will take away part of the low temperature, and at the same time, the human body radiates heat energy to the outside, which basically ensures that the human body needs to keep out the cold.

However, people's physique is different, and many people still have various types of frostbite in winter. Among them, the common frozen hands, frozen feet, frozen ears, and some people will freeze their faces.

I've seen people with frozen faces, their faces are frozen and rotten, no matter what they do, they can't avoid frostbite, and they wrap their faces in towels all day long!

Therefore, people's faces are not necessarily not afraid of freezing, but the special physiological structure of some people leads to frozen faces!

Traditional Chinese medicine calls the head "the meeting of the suns" because all the three yang meridians of the hands and feet reach the head and face and complete the handover, but none of the three yin meridians of the hands and feet reach the head. Therefore, the head is known as the place where all the yang energy gathers, while the masculine is mainly hot, active, and full.

See which part of the whole body has been exposed to the outside for the longest time? Head, of course. I have clothes on my body, shoes and socks under my feet, and even I often wear gloves on my hands, but my face is not afraid of cold, and I have rarely heard of normal people who usually wear masks!

Therefore, the head is the most resistant to freezing, and it is also the most prone to "fever", and it can best reflect the state of qi and blood filling, so as the saying goes, "you don't hit your face", just because your face is "**" when you touch it. In addition, the ** of the face is relatively thin and tender, so it is easiest for yourself and others to observe the human body's qi and blood status, like usually greeting, will say "You look good", how to see it? From the face, of course.

People's faces are not afraid of cold, one is habit, since the birth of the face has been leaking outside, so used to the wind, frost, rain and snow. The second is that there is a protective film on the face, so don't damage the stratum corneum. The third is that the face is easy to protect and can be rubbed with skin care products. In fact, human faces are sometimes prone to frosting.

I also thought about this question some time ago, it may be that people's faces are exposed to the outside for many years regardless of spring, summer, autumn and winter, and they have a certain ability to resist cold, so they are not afraid of cold.

Since the birth of the human face, the human face has been exercised day and night according to the seasons of the year, so that the genes have formed a strong genetic chain and passed on to the baby to adapt to the multiplication of the climate.

Probably because of the thick skin.

The air in winter is generally cold and very dry, and if you don't feel cold in winter, it is mostly directly related to your blood circulation. If your blood circulation is good, you will not feel cold in your face, limbs, or even your whole body.

In addition, the face will not be cold in winter and keep warm is also directly related, because the air is cold in winter, if you wear protective equipment when you go out, such as wearing a helmet or mask, etc., you can reduce the direct contact of your face with the cold air outside, so you will not feel cold. Wearing protective gear in winter not only prevents your face from drying out and chapping, but also prevents the appearance of chilblains.

If you don't feel cold in the winter, and you won't feel hot in the summer when the sun is strong, it may be that the face is not very sensitive and the perception is not very sharp. If it is not accompanied by other discomforts, no diabetes, cerebrovascular diseases, etc., it may be caused by genetic factors, don't worry too much, pay attention to keeping warm in winter, and pay attention to sun protection in summer.

Your situation is currently considered to be caused by yin deficiency, and it is recommended that you drink some Liuwei Dihuang pills appropriately**.

So are you white? If you are white, it must be that you work in the office environment, and the temperature must be relatively high, so your face is always red. Maybe that's the reason, hehe.

If you're used to it, you can't be completely blindfolded, you still have to see things.
