As early as in ancient times, human ancestors were apes with hair all over their bodies, and they continued to evolve over time. Now, the hair on the body is about to disappear in the process of evolution, and it will be replaced by fine hair, but there is a reason.

Hair on the body is also an inevitable physiological phenomenon. The common nose hair, eyebrow hair, armpit hair, and leg hair have their own meanings, especially nose hair, which is also an important line of defense for the human respiratory system. Guarantee the health of the nasal cavity and the human body.

Why do people's nose hair always "channel" out when they are middle-aged?

★Excessive secretion of male hormones

For male friends, if the male hormones in the body are strong, it will affect the normal metabolism level of the body, and also affect the growth rate of hair. All the hairs on the body are in a relatively thick and vigorous state, which also reflects the male side from the side. Strong hormones, the performance of the human body is relatively healthy.

So for male friends, if the nose hair always grows out, it also means that the body's male hormones are strong and the metabolic hormone level is relatively fast, which requires regular conditioning and trimming.

★Environmental pollution

With the acceleration of the pace of life and the development of industrial construction, air pollution is becoming more and more serious. There are air pollution, water pollution, and various waste gas pollution in life.

The human nose is like a corridor, and the nose hair plays a certain security role in this passage. If the air pollution is relatively poor or if you smoke frequently, causing harmful substances to enter the nasal cavity, the nose hair will block these harmful substances. Outside the door, if you don’t breathe fresh air for a long time, it will also increase the workload of the nose hair, and the nose hair will grow more easily.

★Have bad habits

If you have bad habits in your life, such as frequent nose picking or nose hair plucking.

As a result, the nasal mucosa is stimulated and affected. In order to protect the nasal mucosa, the nose hair will grow faster, so it is easier for the nose hair to grow outside the nasal cavity.

★ Genetic factors

I believe everyone knows that genetics is very powerful. From a physiological point of view, the growth rate of nose hair is also affected by genetic factors.

If the immediate family members or blood relatives in the family have thick body hair or nose hair that grows faster and the hair is thicker, then the inheritance to the next generation will also increase.

★ Rhinitis

When in life, the nasal cavity is stimulated by inflammation and the nasal cavity is inflamed, the secretion of the nasal cavity will increase significantly, which will stimulate the nasal hair on the surface of the nasal mucosa, which will lead to the accelerated growth of the nasal hair. Easy to get out of the nose.
