When looking in the mirror, Xiao Wang, who is only 35 years old this year, found that he was young, and his temples began to grow white hair. After carefully observing his face, he found several white hairs mixed in his nose!
It's understandable to have long white hair, but what's the matter with white nose hair? So, Xiao Wang checked on the Internet by himself. Some netizens said that vitiligo might lead to white hair. Could he really have vitiligo?
Out of worry, he immediately registered for medical consultation. The doctor understood Xiao Wang's situation and patiently explained that there are many reasons for the white nose hair after middle age, which is generally normal. However, it is not ruled out that it is caused by disease. If you are not sure, you can conduct targeted examinations to check the cause.
I believe that many friends in life may have the same confusion as Xiao Wang. What is the problem of white nose hair? Do you want to deal with it?
1、 Does white nose hair mean aging?
In life, many people think that the white nose hair is a sign of aging. Does it really mean aging?
Japanese scholar Yoshizawa Kangxiong In 1981, he proposed: Whitening of nasal hair can be used as one of the indicators of aging. He divided the whitening of nose hair into five categories, that is, 2 hairs become white, 1/2 become white, 1/3 become white, 2/3 become white, and all become white.
But humans also have hair, armpit hair, eyebrows and other hair, Why only use whitening nose hair to evaluate aging? This is because there are many reasons for hair whitening, which cannot simply explain that hair whitening is aging. However, hair such as eyebrows, armpits and other hairs age late, which also cannot accurately reflect human aging.
But our country Scholars of Wuhan Medical College They also explored the "relationship between aging and white nose hair" 1905 people of different ages After investigation and analysis, participants found that: 31-35 year old group yes Earliest appearance: white nose hair Group, and In the 51-55 age group, 30% of participants had white nasal hair.
The researchers explained that as people grow older, their body functions continue to deteriorate The synthesis and transportation capacity of melanin also began to weaken It is just because there is not enough melanin, nose hair and other hair will gradually become white. Therefore, researchers believe that the whitening of nasal hair is related to human aging.
In addition, the whitening of nasal hair may also be affected by the following factors:
Genetic factors: Heredity can make the nasal hair white physiologically, such as juvenile white, this white hair disease will cause the nasal hair white.
Disease For example, nasal inflammation will weaken the function of pigment cells in the nasal cavity, and the nose hair will become white due to insufficient melanin synthesis. also Vitiligo Patients will also have varying degrees of difficulty in melanin synthesis, followed by nasal hair and even skin whitening. In addition, Chemotherapy It is easy to affect the supply of hair follicle blood, and may also cause the problem of white nose hair.
Lack of nutrition: Hair growth often requires adequate nutrition, but if the body is chronically deficient Iron, copper and B vitamins And other nutrients, it is easy to make the nose hair white.
Mental impact: Excessive pressure, long-term mental tension and anxiety, it is easy to appear white nose hair.
2、 What does it mean when the nose hair goes out?
I usually chat with my friends face to face, or on an important occasion, I suddenly find my nose hair "fleeing" to the outside, making my image disappear! Why does nose hair come out so disobediently?
In fact, every hair has a growth cycle, which can be divided into Growth Period, Degeneration Period and Rest Period Three stages. Generally speaking, nasal hair The growth cycle is only a few days or so , can be about 0.12 mm long every day, Longest Most of them Not more than 10 mm , the nasal hair will enter into the regression period and the rest period. Then why do some nose hairs grow so vigorously? Most of them can not be separated from the following four reasons:
1. Androgen exuberance
As body hair, nasal hair is also affected by androgen level and the sensitivity of hair follicle to androgen.
2. Environmental factors
For people living in cold areas, hair is a kind of natural insulation layer, so hair like nose hair will grow vigorously in order to keep out the cold.
3. Smoking too much
The harmful substances in cigarettes are easy to stimulate nasal hair follicles, especially when nasal hair is stimulated, its growth speed will be accelerated.
4. He likes to pick his nose
Frequent nostril digging will stimulate the nasal cavity, while bacterial impurities on the hands will also stimulate hair follicles and nasal mucosa, thus accelerating the growth of nasal hair. Frequent nostril digging can even change the direction of the growth of the nose hair, allowing the nose hair to constantly move outward.
3、 Nose hair is too long, can you pull it out directly?
As the first line of defense of the respiratory system, nose hair can help filter out dust, bacteria and large particles of foreign matter into the body and help people breathe clean air. But sometimes the fleeing nose hair is really embarrassing, and many people want to pull it out directly.
This Wang Fei, Head of Dermatology Department, Zhongda Hospital Affiliated to Shoudongnan University express, This is not advisable. It is easy to damage the nasal mucosa by pulling out the nasal hair directly, and bacteria will also "take advantage of the weakness" and cause Infected Question. Even in the nasal cavity furuncle At this time, if it is not handled in time, it is likely to further develop pus spots and pain, and in serious cases, bacteria will enter the blood circulation and cause septicemia 。 In particular, the nose is located in the facial triangle, which is likely to cause Intracranial infection , life threatening.
Therefore, if the nose hair is too long, it should not be pulled out by hand, but should be properly trimmed, but attention should be paid not to cut it too short, and the following points should be paid attention to when cutting:
1. Cleaning and disinfection of nose hair trimming tools
The nasal mucosa is actually very fragile, so the pruning tools used must be cleaned and disinfected, otherwise bacteria may be introduced into the pruning process and cause infection. Especially when there is a wound in the nasal mucosa, it is easier for bacteria to invade the wound and cause nasal boil.
2. The nose hair should be trimmed in a well lit place
The environment for trimming the nasal hair should be as bright as possible. The hair should be trimmed in front of a mirror to avoid damaging the nasal mucosa.
3. Avoid crushing the dangerous triangle when trimming nose hair
The nose is in the dangerous triangle area. When trimming the nose hair, squeeze this area carefully, otherwise the infection may further lead to intracranial infection.
Compared with hair, armpit hair, eyebrows and other hairs, the graying of nose hair can more intuitively judge a person's aging situation, but the graying of nose hair should also be considered to be caused by disease, heredity, malnutrition and other factors. For the problem of exuberant nasal hair, it is not recommended to pull it directly by hand. It is better to trim it carefully with clean and sterilized tools to avoid damaging the nasal mucosa and causing infection.
