The five senses said by the ancients refer to eyebrows, nose, eyes, mouth and ears, eyebrows are often regarded as the first of the five features, and even considered to be the representative of longevity, folk legend: if a man is over 60 years old, the eyebrows become longer, it means that they will live a long life, is this statement true? Is there a scientific basis? Here is the analysis as follows.
Does longer eyebrows mean longevity? Deciphering the relationship between eyebrows and longevity
Judging from the literature, the ancients on the mainland did believe that the elderly with eyebrows would live a long life, and "eyebrow shou" was often used as a word to wish for life, and in the Book of Poetry, July, "for this spring wine, to jie mei shou", which means to brew spring wine in order to seek longevity. There are also ancient documents that record: the flesh is full of beautiful eyebrows, and the eyebrows are long. Eyebrows mean long hairs in the eyebrows, and those who have long hairs are signs of longevity. Wuxia novels also often have white-browed heroes and white-browed Daoists, believing that both long eyebrows and white are long-lived worldly masters.
However, the ancient people lacked evidence-based evidence for looking at problems, and more subjective judgments based on experience, so they lacked scientificity. In response to the problem of the relationship between eyebrow length and longevity, many scientists have conducted studies, and found that the probability of male eyebrows becoming longer after the age of 50 is only 2%, and long-lived people do not necessarily have eyebrows that will become longer.
Scholars have conducted a comparative study of 256 elderly people aged 60-69. The data shows that 72.7% of the longevity population has no eyebrows, but among the 15 centenarians, 7 do not have eyebrows. Therefore, it is concluded that meihao is not a sign of longevity, but is scattered among the elderly.
Scientists pointed out that our normal eyebrows are not always long, the length of the eyebrows is related to genes, so short eyebrows do not worry about poor health or short life. The growth rate of our human eyebrows is much slower than that of hair, basically the growth period is only 2 months, and after stopping growth, it will reach the shedding period, if there are individual eyebrows that do not fall off, it will become longer.
That is what many people call "longevity eyebrows", because with the increase of age, the aging of the body leads to the gradual weakening of the body's cellular metabolism, and it is normal for hair to fall off, especially in men, with the reduction of androgens, the hair also gradually becomes softer and thinner. Eyebrows are also a type of hair, and thinning is also a normal phenomenon. For some people with better hair retention, it will naturally give people an impression of health and longevity, which is why people will think that people with long eyebrows and more hair will live longer.
The cause of the longering of eyebrows in men after the age of 60
In life, we found that some men's eyebrows become longer after the age of 60, which is related to many factors, first of all, in terms of gender, men are indeed more likely than women to have long eyebrows, which is related to men's unique androgens.
Secondly, related to genetic factors, sometimes there is a certain genetic predisposition like hair, that is, when the parents' eyebrows are thicker, they may also inherit the parents' eyebrow state, showing a trend of becoming more and more concentrated. If parents have longer eyebrows, their children will usually also develop long eyebrows.
Finally, related to lifestyle, if men consume more androgen-containing foods and have regular work and rest, they may secrete more androgens in the body, so the hair will be thick and the eyebrows will grow.
Abnormal eyebrow loss requires vigilance
If a person's eyebrows suddenly fall out in a short period of time, and even accompanied by hair loss, there may be a case of cervical vertebrae deviation, eccentric cervical vertebra compression of nerve roots, can cause the brain nervous system, blood supply system supply is insufficient, so that the supply of body hair nutrition is hindered, resulting in eyebrows, hair loss phenomenon. At this time, you need to seek medical attention in time to find out the cause.
epilogue
In short, the length of a man's eyebrows after the age of 60 does not represent longevity, short eyebrows do not represent a short life span, eyebrow length and gender, genetics, lifestyle and other factors are related. If we want to live a long life, we need to eat a balanced diet, exercise actively, control weight, maintain optimism, check up regularly, and stay away from unhealthy lifestyles such as tobacco, alcohol, and staying up late.
