Why do people blush in winter?

The weather in winter is very special. Moving from a warm place to a cold place will accelerate blood circulation and dilate capillaries. There's nothing wrong with that. You can rest assured if there are no other abnormalities.

Remember to apply antifreeze cream after cleansing in the morning and evening, and keep warm.

In medicine, this situation is called "flushing". Every winter, there are many patients.

Blushing is both physiological and pathological. Some healthy people have good peripheral blood circulation, a little activity and rosy complexion; Some people blush when they are shy, angry or ashamed. Some people will blush because of drinking; People living in high mountains need more red blood cells to absorb enough oxygen because the air is thinner, and once the hemoglobin carried by red blood cells increases, the color of their faces will be redder; 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, please consult a doctor.

From a medical point of view, blushing means that it is easier to turn red, darker and lasts longer than others due to changes in temperature or mood. 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 has more to do with the change of temperature.

Generally speaking, heat will dilate skin blood vessels, leading to facial flushing. Although cold makes blood vessels contract, when the temperature rises, blood vessels will rebound and expand, causing blushing. But some people, at extremely cold temperatures, will also blush because of abnormal blood vessel expansion. The clinical manifestations are filiform, punctate, star-shaped or flaky facial features.

When the temperature difference is too large, for example, from the cold wind blowing to the air-conditioned room, it is hot and cold, and the capillaries lose their elasticity in repeated contraction and expansion, which is reflected on the cheeks and nose, which will make the cheeks red and sting. At the beginning, the face can be restored to its original state immediately when it turns red, but if it continues repeatedly for a long time, the blood vessels contract, lose their expansion function, and harden in the state of overstretching, making the face look very red at ordinary times. In severe cases, facial flushing's symptoms will also appear after lowering the head and raising the head. This symptom is relatively calm in spring, summer and autumn, and more serious in winter.

The doctor suggested that in winter, we should avoid the cold environment and the sharp change of temperature, and pay attention to the moisturizing and warm work of the skin. In a particularly dry and hot room, if your face feels dry, you should replenish water in time and wash it with warm water. Scarves or masks can be used outside to prevent cold air from directly attacking the face, avoid excessive humidity difference and temperature difference, and make the dilated capillaries contract rapidly when they are cold, forming red blood. People with a history of facial frostbite should always wipe their faces in winter to promote blood circulation.

In terms of diet, doctors say that people who blush easily should eat less foods that will increase blood vessel dilation, such as coffee, tea, cola and other caffeinated foods. Supplementing some vitamin B can also help nerve repair and soothe the nerves. In addition, avoid sun exposure, alcohol, spicy food, and be less angry, nervous or overly excited, because these will all contribute to the redness of the face.
