Blush

Introduction Blushing is a normal reaction in interpersonal communication and may also be a pathological manifestation of certain diseases. Psychological quality is relatively poor. People who care about other people's opinions will have a sense of tension or excitement when they interact with people who are unfamiliar or more important, and reflexively cause sympathetic excitation, norepinephrine and other catecholamines. Increased secretion, which makes people's heart beat faster, telangiectasia, that is, blushing.

Cause

The human sympathetic nerve is excited, and the secretion of catecholamines such as norepinephrine is increased, so that the heart beats faster and the telangiectasia is blushing.

When you feel embarrassed, your body releases adrenaline. This hormone is a natural stimulant that has a series of effects on the body that are part of the escape response. Adrenaline speeds up your breathing and heartbeat, preparing you to escape danger. Your pupil will be enlarged so you can see as much as possible. Adrenaline also slows down your digestion and re-energizes energy into your muscles. The tremor you feel when you are squatting is the result of all these reactions.

Adrenaline also swells your blood vessels (called vasodilation), speeding up blood flow and oxygen delivery. This is why the face turns red. The blood vessels in the face respond to the signal from the chemical transmitter adenylate cyclase, making adrenaline popular. Finally, the veins on your face will expand, causing more blood to flow through the blood vessels. At this point, your face will turn red and others will know that you are in the middle of it. In other words, adrenaline causes more local blood to flow across the cheeks.

This sounds reasonable, but, interestingly, this is an abnormal reaction to the veins. Other types of blood vessels respond to adrenaline, but usually the veins don't. In other parts of the body, when the adrenaline is released, the veins do not react, and hormones have little or no effect on them.

Drinking or excitement can make us blush, but the blush that appears in the sputum is not the same as these, because only this blush is triggered by adrenaline.

Some people undergo surgery to control their blushing reactions. Erythrophobia is a psychological fear caused by shyness, and patients often blush when they see people. Some people will undergo surgery to remove the tiny nerves that control blush in the spine. This type of surgery is called endothoracic sympathectomy, which has been shown to effectively control blushing.
