When the weather is cold, some people's cheeks turn red. Is this a normal body cold reaction?

It is mainly related to abnormal skin metabolism and allergic reaction caused by environmental changes. In fact, our blushing is rational or morbid. Some healthy people have good peripheral blood circulation. As long as they move a little, their faces will be rosy. Some people blush when they are shy, angry or ashamed. Some people may blush because of drinking. People living in high mountains need more red blood cells to absorb enough oxygen, because the air is thin.

According to the latest news I have learned, once the hemoglobin carried by red blood cells increases, their faces will turn red. Some people blush because of menopause, while others blush because of systemic diseases. Such as hypertension, tuberculosis and lupus erythematosus. Don't worry about physical blushing. As for pathological blushing, you should see a doctor for treatment. Blushing caused by vascular overreaction is not just blushing. From a medical point of view, blushing means that due to the change of temperature or mood, blushing is easier to turn red, darker and lasts longer than others.

There are blood vessels in the skin, which will expand or contract under the influence of nerve factors, especially the capillaries in the cheeks are rich, so the cheeks are more prone to redness. If blushing only occurs in winter, it is more related to the change of temperature. Generally speaking, heat will dilate skin blood vessels, leading to facial flushing. Although cold can cause blood vessels to contract, when the temperature rises, blood vessels will expand elastically, causing blushing. But there are still some people.

In extremely cold temperatures, when the temperature difference is too large, such as from cold air to air-conditioned rooms, cold and hot alternate, and capillaries lose their elasticity in repeated contraction and expansion, which is reflected on cheeks and nose, which will make cheeks red and sting. The face turns red in the early stage and can be restored immediately. But if it is repeated for a long time, the blood vessels will contract, lose their dilating function, and harden in the state of over-expansion, making the face look very red at ordinary times.

Finally, the problem that some people's cheeks turn red when the weather is cold is a normal body cold reaction, so the analysis is here today.
