What are the reasons for redness on both sides of the cheeks

If the sides of your cheeks always turn red easily, you should pay attention to whether it is caused by physiological or pathological reasons. For example, some healthy people with good peripheral blood circulation will blush after a little exercise. There is no need to worry about this problem, but you should be alert to the possibility of disease.

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 living 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.

2. Changes in temperature or mood

From a medical point of view, blushing means that the face becomes 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. Heat causes blood vessels in the skin to dilate

Generally speaking, heat causes blood vessels in the skin to dilate, 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. The clinical manifestations are filamentous, dot-like, star-shaped or flake-like patches on the face.

4. When the temperature difference is too large

For example, when you go from a cold room to an air-conditioned room, and the temperature fluctuates frequently, your capillaries lose elasticity due to repeated contraction and expansion, which is reflected in your cheeks and nose, causing your 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 severe in winter.
