Eyebrows are a type of hair in the human body, and its shape, length, color, etc., can reflect a person's health status, personality traits, fortune changes, etc. In traditional Chinese physiognomy, the eyebrows are known as "Baoshou Gong" and are a symbol of a person's longevity and well-being.
There is a saying that "".The one on the eyebrows is long, and it can rival ten thousand loads of grainIt means that a relatively long eyebrow grows in the eyebrows, which is a sign of longevity and a sign of wealth. Is there a scientific basis for this claim? What does it really mean to have longer eyebrows?
Traditional Chinese medicine believes that eyebrows belong to the foot sun bladder meridian and are the external manifestation of kidney qi. The kidneys are the main water, the main bones, the hair growth, the essence is hidden, and the ears are opened.
People with sufficient kidney qi have strong bones, black hair, bright ears and eyes, full of energy, and strong libido. People with insufficient kidney qi have fragile bones, yellowish hair, deafness and dark eyes, energy failure, and loss of libido.
Eyebrows are an external manifestation of kidney qi, and a person with thick, shiny, long and curved eyebrows indicates that the kidney qi is vigorous, the qi and blood are sufficient, the body is healthy, and the life span is long.
A person with sparse, dull, short, straight eyebrows indicates that the kidney qi is insufficient, the qi and blood are weak, the body is sickly, and the life span is short.
Therefore,Traditional Chinese medicine believes that long eyebrows are a sign of vigorous qi and blood, and are a symbol of good luck, and should not be easily removed, otherwise it will damage the kidney qi and affect health and fortune.
The growth cycle of eyebrows is generally 3-5 months, that is, the eyebrows fall out every 3-5 months and then grow back.
The length and volume of the eyebrows depends mainly on the ratio of the anagen and telogen phases of the eyebrows. The longer the anagen phase and the shorter the telogen phase, the longer and thicker the eyebrows. The shorter the anagen phase and the longer the telogen phase, the shorter and thinner the eyebrows.
The growth cycle of eyebrows is affected by a variety of factors such as age, gender, genetics, diet, hormones, diseases, etc. As we age, the body's metabolism slows down, and the anagen phase of the eyebrows will be correspondingly prolonged, and the telogen phase will be shortened, resulting in longer eyebrows.
This condition is more common in the elderly, and it is also a normal physiological phenomenon, so there is no need to worry too much. However, if the eyebrows suddenly become longer in a short period of time, or accompanied by other abnormal symptoms, such as dry eyebrows, falling out, upturned, etc., it is necessary to be alert to whether there are hidden dangers of other diseases, such as abnormal thyroid function, endocrine disorders, malnutrition, etc., and seek medical examination in time to find out the cause and treat the symptoms.
The shape, length, color, etc., of the eyebrows, are all determined by genes. Genes are carriers of genetic information, and each person has a unique set of genomes, half provided by each parent.
The expression of genes is influenced by both dominant and recessive, with dominant genes suppressing the expression of recessive genes, and recessive genes can only manifest themselves when two recessive genes meet.
Eyebrow length is a dominant genetic trait, which means that as long as one parent has the gene for long eyebrows, then there is a good chance that their child will also have long eyebrows.
Short eyebrows are a recessive genetic trait, which means that a child will have short eyebrows only if both parents have the gene for short eyebrows, and both of them have passed it on to the child.
Therefore, eyebrow length is a genetic decision, an innate trait, not an acquired change, nor a sign of disease, so don't worry too much about it.
