Xiao Miao recently received a post from a boy in the background:
Hello everyone, I'm Xiao Cui. I've always had a problem: my beard has always been thick.
Walking on the streets, I can't help but look at the boys with clean faces, and I feel very envious. Recently, I also saw an article: beards grow fast and have a short lifespan. This made me even more anxious. Does a lot of beard mean that my life will be short?
Today, we're going to talk about "beards and longevity".
1. The frequency of male shaving will affect the life expectancy?
"The faster the beard grows, the longer it will live?" Actually, there is no truth to this statement.
A study that covered 1,000 people and followed them for more than 20 years found that 835 participants died, of whom 45 percent did not shave daily, while those who shaved daily had a nearly 10 percent lower mortality rate.
In addition, a study in the UK of 2,438 people who were followed for 20 years also showed that mortality was relatively higher in those who did not shave daily.
Reading this, friends who don't have the habit of shaving every day, are you worried?
Don't be too nervous, these studies are observational and do not assert a causal link between beard and longevity.
Secondly, by analyzing the common characteristics of the participants, we can find that the frequency of shaving is more related to marriage.
People who don't shave often, most of them are single or divorced, live a rough life, and pay less attention to personal image. And people who shave a lot, most of them are married, and under the influence of their wives, they pay more attention to their appearance and take care of their beards more often.
Beard is only an external characteristic of men, and it has little to do with lifespan. It is recommended that if you want to live a long life, it is more useful to focus more on developing good living habits.
2. The thicker the beard, the stronger the "sexual ability"?
Xiao Miao received a private message from a girl before: "My boyfriend has a lot of beard, I heard that the thicker the boy's beard, the stronger his ability, does this mean that he is not very good?" “
This statement, like "women's private parts have a strong desire for hair", is a misunderstanding.
The growth of beards has nothing to do with ability, but is controlled by male hormones.
Beards grow from hair follicles, and how many beards can have depends on the number of hair follicles. Heredity determines the distribution and number of hair follicles.
The growth and distribution of beards are also largely determined by genetic factors. If a person's father or other members of the family have a thick beard, he is more likely to have a thick beard.
Whether the ability is strong or not is not so simple to see from the surface, which itself is intertwined with physiological, psychological, and life factors:
Age: Sexual function in men decreases with age. A study in the Chinese Journal of Gerontology pointed out that older men are more likely to experience reproductive problems such as low libido and erectile dysfunction.
Health conditions: Many middle-aged and elderly men face various health problems, such as cardiovascular disease, diabetes and chronic diseases such as high blood pressure, which increase the burden on the body and make it difficult for the couple to live as a couple.
Psychological state: Stress, anxiety, depression, and other emotional issues can all make men perform poorly as a couple.
3. These three types of diseases are the most likely to harm men's sexual health
There are 3 diseases that are particularly fond of finding male compatriots, which not only affect physical health, but also become the "killer" of the ability to kill men.
1. Diabetes
Studies have revealed that about one-third of men with diabetes suffer from erectile dysfunction. For diabetic patients who have been ill for more than six years, the proportion is as high as more than 50%.
Penile erection relies on the help of blood vessels and nerves, and long-term high blood sugar levels can damage it, making it prone to diabetic erectile dysfunction.
2. Depression
Psychological research has shown that due to differences in social roles, it is often difficult for men to find appropriate ways to release stress in the face of stress, which makes them more susceptible to various mental illnesses and then sexual dysfunction.
According to World Health Organization statistics on the global burden of disease, depression is expected to become the second most common threat to human health after cardiovascular disease. If a man suffers from depression, his libido decreases.
3. High blood pressure
Endothelial cells play a key role in the blood supply to the penis when it is erect. Long-term high blood pressure can damage the endothelial cells of the blood vessels, which can lead to problems with the blood supply to the penis during erection, which in turn can lead to endothelial cell dysfunction.
Fourth, the behavior of really making men "reduce their life", stop quickly
Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine officially shared some behaviors that harm men's health.
Alcoholism: The Lancet released an extensive study of 28 million people, and the results were impressive – the healthiest amount of alcohol to drink was 0. There is no bottom line to the health risks of drinking alcohol, and even if you try it at a superficial level, it will cause great harm to the body. If you want to live a long life, quitting alcohol is indispensable.
Sedentary lifestyle: Studies have shown that prolonged sedentary behavior is positively associated with cardiovascular mortality. At the same time, sitting for long periods of time can make the genitals susceptible to bacterial infections, which can affect sperm quality.
Excessive indulgence: Frequent conjugal life can shorten sperm production time, reduce sperm count and reduce quality.
Obesity: Obesity leads to a decrease in the secretion of androgens and testosterone in the body, affecting the normal development of sperm.
