What does it mean for middle-aged and elderly men to have longer eyebrows? Does it mean longevity? Know the reason
The 53-year-old Yang Bo found that his eyebrows were so long that he almost covered his eyes, and wanted to go to the barber shop to get his eyebrows trimmed. Who knows, the big brother Wang of the barber shop saw Uncle Yang's long eyebrows, but smiled and said that it was a good thing and could not be cut.
Brother Wang said that since ancient times, long-lived old people have the image of long white eyebrows, which shows that long eyebrows are a feature of longevity, and others can’t ask for it.
After hearing this, Uncle Yang suddenly realized that he had a longevity physique. It seems that after getting old, the longer the eyebrows are, the better, and left with a smile. However, are eyebrows really related to longevity? Why do many people gradually grow their eyebrows after they reach middle age?
1. What is the role of the presence of eyebrows?
Human facial features include eyebrows, eyes, nose, mouth, and ears. The eyes can see the world, the nose can smell, the mouth can eat, and the ears can listen to sounds. As the head of the facial features, what is the role of the eyebrows?
In fact, eyebrows have a great effect on the human body.
Function 1. Block sweat
The main function of eyebrows is to block sweat. Sweating is a normal physiological phenomenon of human beings. Factors such as hot weather, exercise, and spicy food will cause sweating. When sweat is running down, the eyebrows located above the eyes block the sweat and direct it to the nose and cheeks, protecting the eyes from irritation and damage. In addition to being sweat-proof, the brows are also dandruff- and sand-proof.
Function 2, express expression
Various forms of eyebrows, such as uplifting, drooping, stretching, and compacting, can reflect a person's emotions in real time and are the key to many micro-expressions.
It can be said that apart from the eyes, the eyebrows are the organ that can best reveal a person's true thoughts. When FBI personnel in the United States are in contact with people, they always stare at each other's eyes and eyebrows, so as to observe each other's inner world.
Function 3. Affects appearance
The influence of eyebrows on a person's appearance can be described as cosmetic surgery. If the eyebrows look good, then the overall facial features will look more refined. This is why, from ancient times to the present, women from different cultural backgrounds will outline and draw their eyebrows when they make up.
2. What does it mean when the eyebrows of middle-aged and elderly men grow longer?
First of all, can the length of eyebrows really tell the length of life?
In Chinese physiognomy, eyebrows represent Baoshou Palace, and it is believed that a person's lifespan can be judged from the shape of his eyebrows. The representative book of the Jianghu School in the Song Dynasty, "The Complete Compilation of Shenxiang", mentioned that "the eyebrows are long and drooping, and there is no doubt of longevity".
Chinese medicine also believes that whether the eyebrows are thick or not is related to the strength of a person's qi, blood and kidney qi. If a person's eyebrows are sparse, short and fall off easily, it reflects the weakness of Qi and blood. If a person's eyebrows are thick, thick, long and moist, it reflects that his blood is strong and his body is strong.
However, there is actually no scientific basis for a causal link between longevity and long eyebrows . The length of a person's eyebrows is mainly related to two factors: age and hormones.
·age
The growth cycle of eyebrows is relatively short, and it will be renewed every 3-4 months. Due to the fast metabolism of young people, the eyebrows will be constantly renewed, so they cannot grow too long. Each eyebrow can grow up to about 0.4-1 cm in length.
As the metabolism of the elderly slows down , the eyebrows will gradually stop updating, so they will become longer. In other words, the lengthening of the eyebrows is actually a manifestation of the decline of the body's function regulation mechanism.
·hormone
In addition, eyebrows are also affected by hormones in the body. Especially for men, if the level of androgen in the body is too high and the testosterone index is too high, then the hair growth rate will become faster. And with age, the hair follicles become more sensitive, so it is more difficult to resist the stimulation of testosterone, so that the hair growth period becomes longer, so the eyebrows grow stronger.
Although the length of the eyebrows cannot tell the length of a person's lifespan, the eyebrows may indicate a person's physical condition.
1. Whitening of eyebrows
Whitening of the eyebrows may be a precursor to vitiligo . Vitiligo is a disease caused by depigmentation. When vitiligo develops to a certain extent, it will cause the hair to turn white, including the eyebrows.
After suffering from vitiligo on the head and face, the patient's eyebrows will appear white spots, which is due to the loss of melanin, which leads to the gradual whitening of the hair.
2. Partial shedding of the outside of the eyebrows
If the outer part of the eyebrows is partially shed, it may be hypothyroidism or hypopituitarism.
Hypopituitarism can cause hypothyroidism. When the thyroid function is hypothyroid, the metabolic capacity of the whole body will decline, and hair such as eyebrows may fall off due to malnutrition.
3. Eyebrows fall off suddenly overnight
Sudden partial or complete loss of eyebrows, most likely due to alopecia areata . Alopecia areata is a sudden onset of localized patchy hair loss associated with poor sleep, stress and immune abnormalities. When alopecia areata is not controlled in time, it may affect hair other than the hair, such as eyebrows, eyelashes, etc.
4. Young people's eyebrows suddenly grow longer
Peng Yuqing, director of the Pre-treatment Center and the Sub-health Department of Beijing University of Traditional Chinese Medicine Oriental Hospital, said that if the eyebrows of young people suddenly grow longer, it is likely that the regulation mechanism of bodily functions is hindered . This kind of situation usually does not need to worry too much. It is necessary to adjust diet and living habits, ensure regular work and rest, reduce sleepiness and stay up late, exercise more, and recover slowly.
3. Don't pull out the eyebrows casually, think about it before writing the eyebrows
In recent years, more and more people pay attention to the beauty of eyebrows. Usually when modifying the eyebrow shape, many people like to use tweezers to pluck the eyebrows directly. However , plucking eyebrows is not small , and may affect your health.
There are abundant blood vessels and nerves around the eyebrows, and plucking the eyebrows is a bad stimulus to these blood vessels and nerves, which may often cause bleeding, pain and infection, and in severe cases, folliculitis, blurred vision and ptosis. So, don't pluck your eyebrows indiscriminately.
In addition to plucking eyebrows, many people also tattoo their eyebrows. However, eyebrow tattooing itself is a kind of micro-traumatic skin coloring , and the tattooed eyebrows may cause infection, allergy or foreign body due to improper operation of the eyebrow tattoo artist, allergy to dyes and anesthetics or some of their ingredients, autoimmune problems, etc. Granuloma.
In addition, washing eyebrows and coloring are also risky. Therefore, if you have the idea of tattooing eyebrows, it is recommended to go to a professional and formal place and pay attention to whether there is any abnormality.
Changes in eyebrows can reflect the health of the body, but long eyebrows do not necessarily mean longevity . Eyebrows can protect the eyes, express emotions and affect the appearance , and should not be plucked indiscriminately .
