What does it mean when a man's beard grows fast? Does Shaving Frequency Affect Lifespan? science explained to you
How much difference can a boy have before and after shaving?
Yesterday, a female reader complained to Uncle Jiu, saying that her boyfriend was like two people before and after shaving. He has the charm of a mature man when he has a beard, and he looks like a teenager when he is clean . However, she still prefers her boyfriend to grow a beard.
The ancients paid attention to " the long blood will lead to a beautiful long beard, the less blood will have a short beard, and the less blood will have no beard ", which means that men with more beards are healthier. In modern times, beards seem to be more linked to health and are talked about by people.
1. Is the frequency of male shaving related to life expectancy?
There are rumors on the Internet that " the more frequently you shave, the shorter your lifespan ". Is this true?
In response to this problem, the British research team has done relevant investigations and studies.
They observed more than 2,000 middle-aged men, and analyzed whether shaving is related to some diseases. The follow-up investigation lasted for 20 years, and the results were as follows: 45% of people who did not shave every day died, and at least 45% died every day. For those who shaved once a , 31% died (comparatively less).
Looking at the survey results alone, we might conclude that people who shave less often have a higher risk of death.
However, the research team continued to investigate the identities and living habits of the participants and found that most of the people who shave with low frequency are blue-collar workers , and they have irregular work and rest, eating habits, and smoking and drinking habits; while those who shave frequently People are more self-disciplined, their economic conditions are better, and their living habits and image are better.
In other words, whether shaving will affect lifespan has not been directly confirmed . Abraham , a professor in the Department of Social Medicine, said that those who seldom shave have a higher mortality rate, which may be caused by smoking and some social factors, and a small part is also affected by hormones.
Since there is no direct relationship between the frequency of shaving and life expectancy, what is the relationship between the growth rate of beards from other aspects?
- What does the speed of beard growth have to do with it?
Boys usually grow beards after puberty. Some shave once a few days, while others shave in the morning and grow in the afternoon. In fact, the speed of beard growth is related to many factors, the first of which is genetics.
Inherited genes are born and cannot be changed
The growth rate of body hair is inseparable from genetics. If the parents are of the hairy type, there is a high probability that the beard growth rate of their offspring will be relatively faster . In addition to genetic factors, the male hormones secreted by the human body can also affect the growth rate of beards.
The stronger the male hormone, the faster the beard grows
After entering puberty, whether it is a boy or a girl, the body will secrete more androgen, and androgen is the "culprit" that stimulates hair follicles to grow hair, so people with strong androgen secretion will grow beards faster, and androgen Less secretion results in slower growth.
In addition, daily diet and living habits can also affect the growth rate of beards .
Long-term staying up late can lead to excessive secretion of male hormones, high-protein, high-nutrition eating habits will also have a certain effect on promoting the growth rate of beards, which is related to changes in endocrine.
3. The thicker the man's beard, the stronger his sexual ability?
Men with vigorous beards often mislead people into thinking that they are more capable in that area.
In fact, the factors that affect sexual performance are wide and complex, including psychological and spiritual factors, endocrine factors, lifestyle factors, physical strength, etc., androgen is only a small part of endocrine . If a person has a lush beard, but he often suffers from stress, insomnia and anxiety, then his ability may not be very good.
4. A few cold facts about beards
1. In the process of evolution, why didn't the beard fade away?
In ancient times, human beings did not have razors, so they could not easily shave off their beards. Using other sharp tools to shave their beards may hurt themselves instead, and the gains outweigh the losses. More importantly, ancient people believed that long beards can protect the neck and jaw, and it is a natural defensive tool when fighting wild animals.
In addition, Darwin's theory of evolution explains the principle of evolution. Evolution is more about weeding out harmful traits , while some harmless traits that are not obviously useful can usually be retained and tend to be diverse. When the environment stabilizes, humans will not change much in appearance, but the brain will continue to evolve.
As a harmless and external trait, the beard has not faded, which is naturally reasonable.
2. Will the beard grow stronger with shaving?
In fact, this is just an optical illusion. After we shave, the root of the beard is exposed, which looks thicker and darker, and it looks like the beard has become more vigorous.
3. Girls grow beards, maybe they are sick
Generally speaking, due to the higher level of estrogen in women's body, they will not grow noticeable beard. Moustache-like hair growing around the mouth, either due to genetics or excess androgen production during puberty, may be normal or the result of certain medical conditions, such asPolycystic ovary syndrome and Cushing's syndrome caused by endocrine disorders .
Therefore, when women have "mustache", it is necessary to go to the hospital for endocrine examination to rule out disease factors.
4. Don’t take care of your beard, beware of skin diseases
Many men like to grow beards to show the charm of mature men, but beards need to be cleaned and taken care of, otherwise it may cause some diseases.
Dirty and messy beards may lead to clogged hair follicles, breeding bacteria, and skin diseases such as acne and folliculitis , which greatly affect the appearance. If the beard is too long, the food may carry bacteria on the surface of the beard when eating, causing gastrointestinal discomfort. Therefore, it is necessary to clean and manage the beard regularly, which is good for your own health.
In general, it is very necessary for modern adult men to clean their beards regularly, but the frequency of shaving should be arranged according to their actual situation. When shaving, pay attention to hygiene to prevent bacterial infection!
