Why do you feel a little hot and your face turns red?

May be the cause of telangiectasia in the face, which requires improved blood circulation and increased elasticity of capillaries.

Recommendation: Dilate arterioles and capillaries to speed up blood flow and keep capillaries open. Take a look at traditional Chinese medicine, usually eat more fruits and vegetables; Eat less spicy foods.

In medicine, this condition is known as "flushing of the face". Every winter, there are not a few patients. Blush can be both physiological and pathological.

Some healthy people have better peripheral blood circulation, and their complexion is more ruddy after a little activity; Some people blush when they are shy, angry, ashamed; Some people can get flushed from drinking alcohol; People who live in high mountains, because the air is thinner, the body needs more red blood cells to absorb enough oxygen, and once the heme carried by red blood cells increases, the color of the face will be more red; Some people blush due to menopause, and some people can cause blush due to systemic diseases. Such as high blood pressure, tuberculosis, lupus erythematosus, etc. Don't worry about physiological blushing.

As for pathological flushing, it is necessary to consult a doctor. From a medical point of view, a flushed face is one that is more likely to turn red than others due to changes in temperature or mood, and is dark in color and lasts for a long time. **There are blood vessels, which are affected by nerve factors and expand or contract, especially the capillaries in the cheeks, so the cheeks are more prone to redness.

It is formed because of vasodilation in the face.

When it heats up, the blood vessels dilate, and the capillaries in the face are the majority, and the dilation of blood vessels will speed up blood flow and oxygen delivery. That's why the face turns red. The blood vessels in the face respond to a signal from the chemical transmitter adenylyl cyclase, causing an overproduction of adrenaline, and the veins in the face dilate, causing more blood to flow through the blood vessels.

Blushing is caused by the dilation and thickening of blood vessels in the face, which increases blood flow to the face, and the appearance is blushing. Generally speaking, thickening of blood vessels in the face is common when the environment becomes hot.

As soon as the weather is hot, the blood circulation in the human body is faster, because the blood vessels on the face are thinner, and the blood is more abundant here, so it will be red.

When people interact with people they are not familiar with or are more important, they will have a sense of tension or excitement, and reflexively cause the human sympathetic nerve to be excited, and the secretion of catecholamines such as norepinephrine increases, so that the person's heart beats faster and the capillaries dilate, which is manifested as blushing.
