Grandpa, your eyebrows are so long, let me help you cut them off.

Since Uncle Liu turned 50, his eyebrows have become white and long, some of which can already cover his eyes.

Seeing his grandson come over with scissors, he quickly took the scissors from his grandson's hand and explained, "Hey hey, good grandson, Grandpa's eyebrows can't be cut,This is grandpa's longevity blessing. The longer the eyebrows, the longer grandpa lives

Sun Tzu didn't understand anything about longevity and longevity. He only heard his grandfather say he wanted to play with him every day, so he happily agreed. He also said he wanted to water his eyebrows to make them grow longer.

Indeed, not only Uncle Liu, but also many elderly people have this idea. They believe that as they age, their eyebrows and hair will grow white and long, similar to the Taoist Priest of the Immortal Family in traditional cultureThe blessings of longevity, especially the longer the eyebrows, the betterEven if they cover their eyes, many people will not prune it, but will deliberately take care of it, hoping that they can truly live like the legendary fairy, with a lifespan of the same age as the sky.

So is this idea practical? Even if it's not as exaggerated as being the same age as Tian, will those elderly people with long eyebrows really live longer than others? Is lengthening eyebrows really a sign of longevity?

Eyebrows are a type of hair in the human body, located above the eyes and serving to protect the eyes. They can also serve as a way of expressing emotions. Whether the length of eyebrows is related to a person's lifespan has always been a topic of great concern, however,According to current medical research, there is no evidence to suggest a direct correlation between eyebrow length and lifespan, nor is there data to suggest that people with longer eyebrows will live longer than others.

Firstly, the growth of eyebrows and human lifespan are different physiological processes, and there is no direct correlation between the two.The growth rate of eyebrows is related to individual genetic factors, hormone levels, age, and other factors. Some studies have shown that men have more eyebrows, grow faster, and have a wider range, while women have relatively fewer eyebrows. butBoth male and female eyebrows will not have a direct impact on lifespan under normal circumstances.

Secondly, the determinants of human lifespan are very diverse, includingGenetic factors, environmental factors, health status, lifestyleEtc. Although some factors can affect the growth of eyebrows to a certain extent, their impact on lifespan cannot be simply attributed to the length of eyebrows.

For example, factors such as diseases, malnutrition, or drug side effects may cause thinning or shedding of eyebrows, while healthier lifestyle habits such as regular exercise and a reasonable diet may promote the growth of body hair, including eyebrows. However, these factors can only indirectly reflect the health status of the body and cannot directly represent the length of a person's lifespan.

In ancient China, due to difficult conditions and backward medical standards, people's lifespan was not long, and many people generally could only live until35-45 years oldLeft and right, so there is a persistence and longing for longevity, when a person lives to50 years oldMany people will consider certain characteristics of their bodies asA symbol of longevity. The eyebrows, which are located on the face and are easy to detect changes, are naturally regarded as a sign of longevity by everyone.

In later traditional Taoist culture, people often portrayed the portrayal of immortals as benevolentWhite whiskers flutteringA fairy like appearance, especially the eyebrows, which are white and long. Riding on a crane and swaying with the wind along with the clothes and dust, giving people an image of being free from worldly affairs and wandering with objects. Due to the fact that immortals are generally transcendent and cross reincarnation, they are often used to represent longevity and longevity.

So, when an elderly person has white hair, fluttering whiskers, and kind looks, people will crown them with the image of a fairy to congratulate them on their long life and longevityMore of a kind of birthday greetingAt least so far, it has not been studied or demonstrated in medicine. So, what does it mean to have longer eyebrows?

50 years old

1. Aging of body skin

Aging of the body's skin is one of the reasons for eyebrow elongation. In youth, the eyebrows of a person are generally close to the skin and grow upwards, but as they age,The skin gradually loses its elasticity and begins to droop, causing the eyebrows to follow suit. Visually, this creates an illusion of eyebrow elongationOf course, it cannot be ruled out that the eyebrows themselves are slightly longer.

amongCollagen is one of the main components of the skin, which can help maintain elasticity and firmness. As we age, the body gradually reduces the absorption and synthesis of these proteins, gradually losing them, leading to skin relaxation and sagging. The skin below the eyebrows is relatively thin and is particularly susceptible to this effect.

Additionally,The reduction of skin muscles and fat is also one of the reasons that affects eyebrow droop. As one gets older, the digestive and absorption functions of the body's intestines and stomach decrease, and the body is unable to fully obtain and utilize nutrients, resulting in the gradual depletion of muscles and fat in the lower layer of the skin, lacking the necessary support, and the skin on the eyebrows will naturally droop downwards.

2. Increased androgen levels

Androgen is an important component of male hormones and an endocrine hormone secreted by the male gonads. It can promote and maintain the physiological development and metabolism of the male body.Elevated levels of male hormones can promote hair follicle growth, increase hair growth cycle, and terminate hair growth time, thereby increasing the growth level of eyebrows and other hair.

50 years old.

Foods with high androgen levels includeLamb, beef, chickenAnimal protein foods, some foods containing plant androgens, such asSoybean products, grains, and nutsFood and other factors may also increase the content of androgens in the body.

3Adequate nutrition intake

The growth of body hair, including eyebrows, requires a lot of nutrients to support. When certain parts of the body hair, such asWhen eyebrows accelerate growth, it may be due to recent sufficient intake of nutrientsNutrients that can promote eyebrow growth include the following.

The main component of eyebrows is keratin, andproteinproteinprotein.

Additionally,proteinprotein.

proteinNot only that, it can also help control scalp oil secretion, provide sufficient nutrition for hair, and form a barrier to prevent hair follicles from being attacked by bacteria,Reduced the risk of eyebrow detachment and breakage.

Therefore, when the body consumes enough of the above nutrients, the growth environment and speed of eyebrows can be improved.

Although the length of eyebrows is not closely related to human lifespan, this issue also represents people's pursuit and persistence in longevity. We have never given up research on this aspect. Recently, a new study shows that humans are one step closer to the secret of longevity.

Published in The Lancet in 2023, titledMulti modal profilingofperipheralboodcells across the human life span, received, registered, and effective cell signatures of origin and long evityThe article is a study on the characteristics of blood cells and human lifespan. This study found that human blood cells exhibit different immune cell characteristics at different stages of life, which may be related to human lifespan and health status.

The researchers selected individuals from different age groups7 anonymous long-lived elderly (average age 106 years)75220-89Flow cytometryprotein.

This study focused on analyzing a variety of immune cell subsets, including Natural killer cell, T cells and B cells, and explored the relationship between different factors and age by combining the multi factor linear regression modelImmune cell characteristics of longevity and aging.

Overall, this study provides the first comprehensive analysis of the immune characteristics of human blood cells in terms of age and longevity, and reveals differences in the number, diversity, and function of immune cells at different stages,Important breakthroughs have been made in exploring human lifespan and the pathogenesis of aging.
