Why is there blushing in cold weather?

The south is a bit strange this winter. I just flew from Guiyang to Hebei yesterday. When I got off the plane, someone always cast a strange look, only to find that everyone else was wearing thick clothes. I was wearing autumn clothes, which was particularly different.

Let's explain why you blush in winter. From a medical point of view, people blush because we go from a warm place to a cold place, which will accelerate blood circulation, lead to telangiectasia, and lead to "flushing" on the face.

Among them, in winter, the inner flush is rational and morbid. Don't worry about physical blushing. As for pathological blushing, please consult a doctor. Because the outdoor temperature may be too low, facial flushing may also be due to frostbite, so when you go out in winter, remember to apply antifreeze after cleansing and keep warm.

This "red face" phenomenon appears in the cold winter, and it will happen to everyone in the cold winter of our country. Modern people call it "Plateau Red". The main reason is that the cold weather in winter and the poor warmth of the face make the blood unable to circulate normally, temporarily blocking all the capillaries on the face and naturally forming the red color of plasma. If the freezing time is short, it will naturally return to normal after heating. People who have been frozen for a long time will form "plateau red" on their faces. I hope that in the cold winter, I must pay attention to keeping my face warm to prevent my face from freezing.

It is people's self-protection function and plays a role. In the cold season, people who generally remember the year often turn yellow because of insufficient blood supply at both ends of themselves. The face is red, which usually appears on the faces of young adults. This shows that his (her) facial microvascular congestion is strong. However, there is another phenomenon of facial redness that needs everyone's attention: the cold allergic reaction of the face. In other words: when the face encounters cold stimulation, there will also be a red allergic reaction. Usually take some anti-allergic medicine, or go to the warm circle, and your face will soon turn red.

This is the effect of qi and blood circulation casting. It is not a good phenomenon for people to blush in winter. In the north, people whose temperature is above-10 degrees, or who encounter the cold wind blowing from the northwest, often have this image, and the general red color also has a bright and swollen image. The main reason is that the weather is cold, the blood temperature is low and inactive, and the circulation is slow. Qi and blood run to the face, which is oppressed by strong cold, and the facial muscles are tense and suddenly contract, making it difficult for blood to circulate. However, the facial capillaries are closed because of the cold, so they can't open their mouths to discharge the blood gas released by facial muscles, and they can't achieve the effect of circulation, resulting in the phenomenon of blood gas rising internally, so they will be red and bright.

Because of the cold weather, the human body's natural reaction to temperature.

In winter, when the weather is cold, people's bodies are hot. When the weather is hot and cold, people's faces turn red. When a person blushes, his body temperature is rising to prevent catching a cold. In winter, people's pores are closed, so the heat in the body can't be emitted. In cold weather, the skin temperature of the face will rise and people's faces will feel redder than usual.

When the weather is cold, it will stimulate the body's temperature receptors, and the brain will regulate the body to produce corresponding hormones to act on blood vessels, stimulating the expansion of human capillaries and increasing heat production, so the face looks red.

Are you testing my medical knowledge? I'm not a doctor, I can only give a rough idea. As far as medical phenomena are concerned, blushing must be caused by the concentration of blood on the face and skin. In winter, our face is usually exposed to the outside world, and the skin of the face will be stimulated by low temperature, so blood will flood here. When you enter a warm environment, the blood will not flow back quickly, and you will blush at this time. This is your normal physiological reaction from a cold environment to a hot environment. I think there should be no problem, but according to the way you blush, I guess your face is still white. Ha ha laugh

The main reason for blushing in winter is that the temperature is too low and the skin is frozen.

In cold weather, the skin exposed under clothes has no protection and is directly exposed to the cold. Natural skin has a thin stratum corneum, which is easily stimulated by the external environment, leading to vasodilation, red blood, and easy swelling.

Because of the heavy cold, the blood is frozen purple.
