Is 'whitening nose hair' a sign of aging in men? There may be other situations that should be paid more attention to

Most animals have hair in their bodies, mainly to protect their health, but also to provide warmth. In fact, there are many hairs in the human body, but they cover different parts and grow in different states.

However, we are more familiar with hair and hair on the body. We also have some hair inside our nose. However, many male friends often remove their nose hairs because too much nose hair can affect their appearance.

Nose hair is a special kind of hair that acts as a tactile auxiliary sensor inside the nasal cavity, as the first line of immunity in the respiratory system and inside the nasal cavity.

In order to maintain healthy breathing in the nasal cavity, nasal hairs may block dust and particles in the air, preventing flying insects and fine particles from entering the nasal cavity.

01 What is the function of nose hair?

1. Effective blocking of dust.

The air quality in nature is getting worse and worse, especially in autumn and winter, it is very prone to haze weather. There are many small particles in the haze weather. Every breath will cause some harmful substances, but the existence of nose hair is very convenient. It is able to prevent external dust from entering the respiratory system.

Effectively filter inhaled oxygen, safe enough to bring a purification effect to yourself. The cilia in the nose hairs allow some bacteria to enter the stomach, where they are digested by stomach acid.

2. Nasal mucosa temperature protection.

The cold air from the outside enters the body, especially in winter, the cold air is cold and dry, which can not only filter the air, but also maintain the surface temperature of the nasal mucosa and prevent the cold air from entering the body.

3. Maintenance of olfactory health.

We all know that food is judged by its smell, but the nose is also a sensor of smell. As a protection for the olfactory nerve, nose hair is closely related to appetite. The aroma of food can stimulate people's taste buds and increase their desire to eat.

I don't know if you have discovered that with the increase of age, the aging speed of the human body will continue to accelerate, and the nose hair will also become longer and longer.

Especially for male friends, in middle age, there will be white marks on the nose hair. Many people think it's a classic sign of aging, like graying hair. What is the truth?

02 Is the precursor of aging a whitening of male nose hair?

Asian hair is black, mainly because the keratin protein in the hair is composed of amino acids, including tyrosine, which is converted into melanin under the action of tyrosinase, so the hair is black.

There will be some obstacles in the process of melanin production. If there is a lack of tyrosine or tyrosinase in the body, the activity is reduced, melanin cannot be synthesized, and the hair will gradually turn white.

This is mainly divided into the following three reasons. If the color of the nose hair turns white, it is more helpful to judge the degree of aging of the human body.

First, compared to hair, the number of eyelashes is less and the degree of whitening is clearer, so it is easy to judge. The second reason is that many people go bald or even completely bald in middle age. However, the problem doesn't exist in their nose hair, and they basically don't go bald.

Third, due to the influence of external factors and human factors on the existence of hair on the surface of the human body, it is more likely to appear white, but the nose hair in the nasal cavity is less affected and the judgment is more accurate.

Medical researchers in Japan did a survey. The researchers followed 300 adult men between the ages of 18 and 65 to investigate the effects of chronological age and the whiteness of nasal hair.

According to the data, the albinism rate of nose hair is basically 0 for 20-25 year olds, about 6.3% for 21-25 year olds, and 19.8% for 26-30 year olds.

The albinism rate of nose hair is about 28.5% between 31 and 35 years old, about 64.3% between 36 and 40 years old, and 93.85% over 46 years old.

In China, the whitening of nose hair first appears between the ages of 31 and 35, with a whitening rate of less than 350% and over 38.9% of the time.

To some extent, the whiteness of the nose hair increases with age, that is, the whiteness of the nose hair is due to the aging of the body, so the whiteness of the nose hair must be aging? Perhaps there are other factors to consider.

03 The whitening of nose hair is not necessarily aging, and there may be other conditions, which should be paid more attention.

1. Kidney deficiency

With the rapid development of China's economy, the pace of life is getting faster and faster, and the pressure of work, study and life is increasing. Overwork, staying up late and malnutrition will all lead to kidney deficiency.

From the perspective of traditional Chinese medicine, the root of hair is the kidney qi. When the kidney qi is sufficient, the hair will also turn black and bright. When the kidney qi is insufficient, if the hair is not nourished and nourished, the hair will turn white.

If the color of the nose hair is white, we should consider whether it is caused by insufficient kidney qi. If the western medicine counterpart is an endocrine disorder, the melanin will continue to decrease, causing the hair to suddenly turn gray, especially for those who stay up late for a long time.

2. There are lesions in the nasal cavity.

If the nasal cavity is serious or the bacterial infection is not controlled in time, the state of nasal hair growth in the nasal cavity is easily affected by the forced robbery environment, which can easily lead to nasal cavity damage, affect the synthesis of melanin hair follicles, and cause hair to turn white.

3. Decreased lung function.

In traditional Chinese medicine, it is often said that the lungs govern the skin, its beauty is in the hair, and its openings are in the nose.

The meaning of this sentence mainly means that when the lung function is good, if the lung function declines or other diseases, the nutrients of the body can be distributed on the epidermis, moisturizing the hair, keeping the hair healthy, and the hair becomes darker and brighter.

When there is a problem with the lungs, the color of the nose hair will gradually turn white, because the health of the lungs and the nose belong to one system.

4. Effects of cigarettes.

As we all know, smoking is harmful to health, but in my country there are still many people who smoke, especially male friends, even older smoking age.

If you smoke for a long time, your fixed soy choline component will attach to the nose hair in the cigarette and inhibit the production of melanin in the nose hair follicles. In addition, long-term smoking can damage lung health, so hair will gradually gray.

5. Blocks nutrition.

When the body's metabolism is affected, or the body lacks the supply of these nutrients, the reason why human hair appears black is closely related to trace elements, especially iron and copper, which are caused by the body's metabolism. .

For people who are undernourished or excessively losing weight, we may wish to take a closer look. Their hair becomes more irritable. The reason for the yellowing is that the metabolism is blocked and the nutrient supply is insufficient.
