People with long eyebrows live longer? Eyebrows grow longer after the age of 50, is it a good thing or a bad thing?
As the saying goes: "A long eyebrow can live a long life." Since ancient times, long eyebrows have been regarded as a symbol of "longevity". For example, the image of Shou Xinggong in film and television dramas has soft and long eyebrows, hanging down to the cheeks, looking kind and kind, with a fairy spirit. In real life, some middle-aged and elderly men suddenly find that their eyebrows have become longer than before.
According to the folk saying, the eyebrows are called "baoshou palace". The eyebrows that suddenly become longer are usually regarded as "longevity eyebrows". When a person reaches middle age, the eyebrows suddenly become longer, which means that the person will live a long life, which is a good omen. So, what does it mean to have longer eyebrows? Is it really a harbinger of longevity?
- Is "longevity eyebrow" really "longevity"? =============================================
Longevity eyebrows refer to the sudden elongation of the eyebrows at the corners of the eyebrows and the eyebrows, which generally appear with age, and usually appear in middle-aged and elderly men. In fact, eyebrows, as one of the components of human facial features, do play important functions, but they do not mean "longevity".
First of all, the basic function of eyebrows is to act as a "shield" for the eyes, which allows liquid to flow down the sides instead of directly seeping into our eyes. At the same time, eyebrows can also help us convey emotional signals in interpersonal communication, such as expressing "surprise" by "raised eyebrows" and venting "dissatisfaction" with "frowning".
In addition, eyebrows, like hair, are closely related to the qi and blood in the human body, and can reflect the health status of the human body.
Director Peng Yuqing of the Dongfang Hospital of Beijing University of Traditional Chinese Medicine also mentioned: "The eyebrows can indirectly reflect the longevity of the elderly." Traditional Chinese medicine believes that the eyebrows belong to the "kidney essence " . Lack of gas.
But experts also stress that this situation only applies to the elderly . For young people, this is not the case. Some young people have naturally thin eyebrows, while others are naturally thick, which cannot be simply inferred. Seeing this, some friends may feel puzzled, since growing eyebrows is not a sign of "longevity", what causes it?
- Why do some people have longer eyebrows after the age of 50? ====================================================================
In fact, there are many opinions in the academic circles about the reasons for the elongated eyebrows. One view is that "longevity eyebrows" are the same as "white hair" and "senile diseases", and are caused by aging. Some people also claim that "longevity eyebrows" not only have nothing to do with longevity, but may also be a sign of disease. In general, it can be divided into the following four reasons:
1. Slow metabolism
According to research, the renewal cycle of human tissue cells is about 120 days to 200 days, and all new cells can be renewed in about 6 to 7 years. The renewal time of hair is 3 to 6 years.
However, the renewal frequency of the eyebrows is relatively fast. Under normal circumstances, the renewal will be carried out in 3 to 4 months , so the length of the eyebrows is generally only maintained at about 0.4 cm to 1 cm.
The metabolism of young people is usually very fast, while the metabolic level of middle-aged and elderly people will also slow down due to the decline of physical function . As the age increases, the metabolism becomes slower and slower. This causes the eyebrows to no longer be renewed frequently, the growth cycle of the hair follicles is getting longer and longer, and the old and new ones stop, and finally the eyebrows become longer.
Eyebrows elongated due to metabolism is the most common condition. Middle-aged and elderly friends don’t need to worry, this is a normal growth law. But it should be noted that you should exercise more and drink plenty of water. Otherwise, due to the low level of metabolism, toxins will accumulate more and more . If things go on like this, it is easy to suffer from senile metabolic syndrome, diabetes, high blood pressure, blood lipid metabolism disorders and other symptoms.
2. Nutrition intake
The human body needs to take in a lot of nutrients in order to maintain the normal operation of body organs and the growth of body surface hair. Because the growth and development of hair follicles need protein and vitamins , these two are the most common and very important nutrients, if you take in more, the hair will be strong, and if you take in less, the hair will be sparse.
Therefore, when we see someone else's hair is black and thick, we will subconsciously think that the other person is well-nourished. On the contrary, if we see someone else's hair is withered and yellow, we will habitually think that the other person is malnourished. The same is true for eyebrows. The hair and eyebrows of middle-aged and elderly people become longer, in addition to the metabolism level mentioned above, it may also be due to adequate nutrition.
This also coincides with the "eyebrows belong to the kidney essence" mentioned above. Sufficient nutrition leads to sufficient kidney essence; sufficient kidney essence maintains good health; good health can be regarded as a side reflection of "longevity". Therefore, it is recommended that middle-aged and elderly friends should eat some eggs, beans and other foods in their daily life to maintain nutritional intake.
3. Hormone levels
Human hair growth is not only affected by nutrients, but also closely related to male hormones. The more male hormones are secreted, the thicker and thicker the hair on the body surface will be . For example, we often describe a man with "thick eyebrows and big eyes", because men's body hair will appear thicker than women's.
The sudden elongation of the eyebrows may be due to a sudden increase in the level of male hormones in the body. Especially for middle-aged and elderly people, the organ activity of the body has already begun to decrease, and the androgen accumulated in the body cannot be consumed by other organs, so it will act on the eyebrows, causing the eyebrows to suddenly grow longer.
In addition, androgen abnormalities are also related to diet . If you eat too much animal offal, dog meat, mutton and other foods , the hormone level in the body will increase, causing the endocrine balance to be disrupted, resulting in longer hair and even various complications. Therefore, when the eyebrows become longer, we should also pay attention to a balanced diet.
4. Genetic factors
Genetic factors have a particularly powerful force, ubiquitous from head to toe, from the inside to the outside, can easily affect people's body and mind, and even run through life. Some scholars believe that the longer eyebrows are largely related to genetic factors . Because the thickness of the eyebrows, and even the shape of the eyebrows, will be inherited from the genes of the parents.
Assuming that the father or mother has thin eyebrows, the child's eyebrows may also be thin since childhood, unless it is improved by means such as eyebrow transplantation. But this situation is not absolute, but there are some individual differences. For example, although the shape of some children's eyebrows is the same as that of their mothers, they look short and few, and they only become long and thick after a few years .
Some middle-aged and elderly friends didn't have very long eyebrows at first, but when they reached the age of fifty, their eyebrows suddenly became longer for no reason. It may be because genetic factors began to play a role. Some family genes that were silent in the body gradually "appeared" Mountain Dew".
