Do people with long eyebrows live longer? Longer eyebrows after 50, is it a good thing or a bad thing?
There is a saying: "A long eyebrow is a long life." Since ancient times, long eyebrows have been regarded as a symbol of "longevity". For example, the image of Shou Xinggong in the film and television drama, that is, the eyebrows are long and soft, hanging down to the cheeks, looking kind-hearted and immortal. In real life, some middle-aged and elderly men suddenly find that their eyebrows have become longer than before.
According to folklore, eyebrows are called "baoshou palace". The eyebrows that suddenly grow long are usually regarded as "longevity eyebrows". When a person reaches middle and old age, the eyebrows suddenly grow longer, which means that the person will live a long life, which is a good omen. So, what does long eyebrows mean? Is it really a harbinger of longevity?
- Is "longevity eyebrow" really "longevity"? =============================================
Longevity eyebrows refer to the phenomenon that the eyebrows at the corners of the eyebrows and the eyebrows suddenly become longer. It usually occurs with age, and it usually occurs in middle-aged and elderly men. In fact, as one of the components of human facial features, eyebrows do play an important function, but it does not mean "longevity".
First of all, the basic function of eyebrows is to act as an "umbrella" for the eyes, allowing fluids to run down the sides rather than seeping directly into our eyes. At the same time, eyebrows can also help us transmit emotional signals during interpersonal communication, such as expressing "surprise" by "raising the eyebrows" and expressing "dissatisfaction" by "frowning".
In addition, eyebrows, like hair, are closely related to the qi and blood in the human body, and can reflect the health of the human body.
Peng Yuqing, director of the Oriental Hospital of Beijing University of Traditional Chinese Medicine, also mentioned: "The eyebrows can indirectly reflect the lifespan of the elderly." Traditional Chinese medicine believes that the eyebrows are "belonging to the essence of the kidney " . Lack of air.
But experts also stress that this applies only to the elderly . For young people, this is not the case. Some young people are born with thin eyebrows and some are born with thick eyebrows, which cannot be simply inferred. Seeing this, some friends may feel puzzled. Since long eyebrows are not a sign of "longevity", what is the cause?
- Why do some people have longer eyebrows after the age of 50? ====================================================================
In fact, there are many opinions in the academic world as to why the eyebrows grow longer. One view holds that "longevity eyebrows" are no different from "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. Generally speaking, it can be divided into the following four reasons:
1. Slow metabolism
According to research, the cycle of human tissue cell renewal is about 120 to 200 days, and it can be completely renewed into new cells in about 6 to 7 years, and the renewal time of hair is 3 to 6 years.
However, the update frequency of the eyebrows is relatively fast. Under normal circumstances, it will be updated every 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 fast, while the metabolic level of middle-aged and elderly people will also slow down due to the decline of physical function . As they grow older, the metabolism becomes slower and slower. This leads to the fact that the eyebrows are no longer updated frequently, the growth cycle of the hair follicles is getting longer and longer, and the old ones are stopped to produce the new ones, and finally the eyebrows become longer.
The growth of eyebrows due to metabolism is the most common situation. Middle-aged and elderly friends do not need to worry, this is a normal growth law. However, it should be noted that you should exercise more and drink more water on a daily basis. Otherwise, due to the low level of metabolism, toxins will accumulate more and more , and if things go on like this, it is easy to suffer from senile metabolic syndrome, and symptoms such as diabetes, hypertension, and blood lipid metabolism disorders will appear.
2. Nutritional intake
The human body needs a large amount of nutrients in order to maintain the normal functioning of the body's organs and the growth of hair on the body surface. Because the growth and development of hair follicles requires protein and vitamins , these two are the most common and very important nutrients, more intake, strong hair, less intake, sparse hair.
Therefore, when we see other people's hair black and thick, we will subconsciously think that the other party is well nourished. On the contrary, if we see other people's hair wither and yellow, we will habitually think that the other party is malnourished. The same is true for eyebrows. The hair and eyebrows of middle-aged and elderly people become longer. In addition to the metabolic level mentioned above, it may also be due to adequate nutrition.
This also coincides with the aforementioned "eyebrows belong to the kidney essence". Sufficient nutrition leads to sufficient kidney essence; sufficient kidney essence means good health; good health can be regarded as a side reflection of "longevity". Therefore, it is recommended that middle-aged and elderly friends eat some eggs, beans and other foods appropriately 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 the hair on the body surface . For example, we often describe a man with "thick eyebrows and big eyes" because men's body hair is thicker than women's.
The sudden lengthening 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 male hormones accumulated in the body cannot be consumed by other organs, and will act on the eyebrows, causing the eyebrows to suddenly grow.
In addition, androgen abnormalities are also related to diet . If you take too much animal offal, dog meat, mutton and other foods , the hormone level in the body will increase, resulting in the breakdown of the endocrine balance, resulting in longer hair, and even leading to 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. They are omnipresent from head to toe, from inside to outside. They can easily affect people's body and mind, and even run through life. Some scholars believe that the lengthening of eyebrows is largely related to genetic factors . Because the thickness of the eyebrows, and even the shape of the eyebrows, will be inherited from the parents' genes.
Assuming that the father or mother has sparse eyebrows, the child's eyebrows may also be sparse from an early age, unless it is improved through methods such as eyebrow transplants. But this situation is not absolute, but there are some individual differences. For example, some children's eyebrows, although the shape is the same as the mother's, look short and thin, and only become long and thick after a few years .
Some middle-aged and elderly friends do not have very long eyebrows at first, but when they are around 50 years old, their eyebrows suddenly grow longer inexplicably. It may be because genetic factors begin to play a role, and some family genes that are silent in the body gradually become "significant" in the middle and late stages. Mountain dew".
