Why does your face turn red in winter? Here are 4 reasons to know

In winter, many people's faces will have a large red area, like high altitude erythema. This is because the alternation of cold and hot weather in winter or the thinner facial skin will cause blushing in winter.

Alternating hot and cold

When we walk from a warm room to a cold outside, our face is suddenly stimulated by the cold. In order to protect itself, the body increases the blood supply to the face and constricts the capillaries to resist the cold outside. Due to the contraction of capillaries and insufficient blood supply to the face, the face will appear red.

Psychological tension, excitement

Many times we will encounter times when we are nervous and excited, and at this time we will always unconsciously feel our face getting red and hot. This is because when we are nervous and excited, our heartbeat will speed up and blood circulation throughout the body will speed up. Since the blood vessels in the face have no venous valves (valves to prevent blood from flowing back) and the blood vessels are relaxed, they react most sensitively, so the face will turn red.

Thin facial skin

There are many pathological conditions that cause the skin on our face to become thinner. The weather is relatively cold in winter, and the body will supply more blood to the face in order to protect itself, causing the face to turn red. In mild cases, the face will just turn red, but in more severe cases, there will be red bloodshot and cracks on the face. In this case, it is recommended to go to the hospital for timely treatment.

Physical pathological manifestations

In medical diagnosis, there is a concept called "highland redness" (redness of the cheekbones). Highland redness is mostly a pathological manifestation caused by poor heart function or poor respiratory and circulatory function. In traditional Chinese medicine, redness and heat in the face are caused by poor functioning of the heart, liver, and lungs. The heart cannot transport blood to the body in time, and the liver and lungs cannot metabolize blood in time. Of course, there are other diseases as well, such as heart disease, tumors, etc.
