What causes frequent blushing

Many people are troubled by frequent blushing. Some of the blushing is caused by physiological factors, while others are caused by pathological reasons. Therefore, it is necessary to understand the real reason. For example, patients with high blood pressure, tuberculosis and lupus erythematosus may suffer from these symptoms.

1. Blushing can be physiological or pathological. Some healthy people have better peripheral blood circulation, and their complexion will be rosy after a little activity; some people will blush when they are shy, angry or ashamed; some people may blush due to drinking; people who live in the mountains, because the air is thinner, the body needs more red blood cells to absorb enough oxygen, and once the hemoglobin carried by red blood cells increases, the color of the face will be redder; some people blush due to menopause, some people blush due to systemic diseases. Such as hypertension, tuberculosis, lupus erythematosus, etc. Don't worry about physiological blushing. As for pathological blushing, you should consult a doctor.

2. From a medical point of view, blushing means that the face turns redder more easily than other people due to changes in temperature or emotions, and the color is darker and lasts longer. There are blood vessels in the skin, which expand or contract due to nerve factors. Especially the cheeks are rich in capillaries, so the cheeks are more likely to turn red. If facial blushing only occurs in winter, it has more to do with temperature changes.

3. Generally speaking, heat will dilate blood vessels in the skin, causing facial flushing. Although cold causes blood vessels to constrict, when the temperature rises, the blood vessels will rebound and expand, causing blushing. But for some people, blushing may occur due to abnormal dilation of blood vessels in extremely cold temperatures. Clinical manifestations include filamentous, dot-like, star-shaped or flake-like patches on the face.

4. When the temperature difference is too large, such as going from a cold room to an air-conditioned room, and the temperature fluctuates between hot and cold, the capillaries lose their elasticity during repeated contraction and expansion, which is reflected in the cheeks and nose, causing the cheeks to become red and stinging. In the early stages, the face will turn red and return to its original state immediately, but if it continues for a long time, the blood vessels will contract, lose their dilation function, and harden in an over-dilated state, making the face look red even at normal times. In severe cases, facial flushing may occur after lowering the head and then raising it again. This symptom is relatively mild in spring, summer and autumn, but becomes more severe in winter.
