Usually, when people observe their fingers, they can often see the white crescent on the nail cover.
Chinese medicine believes that the size and presence of the crescent on the nail cover is an important indication reflecting the degree of prosperity and decline of human qi and blood, if the curvature of the crescent on a person's fingernails is both large and shiny, it means that the person's qi and blood are relatively vigorous and healthy;
However, if the crescent on a person's nails is relatively small, or even disappears, it indicates that there are different degrees of decline in the person's qi and blood, and it is also necessary to regulate the qi and blood as soon as possible.
So, is it necessary to have a crescent on the nail to be healthy? The changes in the crescent may also be related to these 3 points.
1. Thyroid disease
The thyroid gland is one of the important immune organs of the human body, and the thyroid hormones it is involved in the secretion of regulate the body's metabolism, and the size of the crescent or the presence or absence of stool happens to be a "display" that reflects the speed of metabolism.
When people are hyperthyroid, it will accelerate the speed of metabolism in the body, and at the same time will drive the rapid growth of nails, so that the translucent keratin (that is, "crescent") in the nails that has not completely faded suddenly increases, which will make us see a very full crescent state.
When the thyroid function is reduced, it will slow down the speed of metabolism in the body, thereby slowing down the growth rate of nails, nail length is slow, the keratin in the nail has tended to mature, and when it is not supplemented by new substances, it will become smaller and smaller, or even disappear.
If you accidentally find that the crescent moon is suddenly large and small, you can perform thyroid-related examinations to identify whether you have hyperthyroidism or hypothyroidism, but if the crescent does not change much for a long time, you do not need to pay too much attention, usually pay attention to maintenance.
2. Seriously ill or malnourished
A smaller crescent or no crescent may also occur when a person's body has a major illness or suffers from severe malnutrition.
This is mainly due to the lack of nutrients in the body or the destruction of diseases, resulting in keratin cells can not be supplied with sufficient nutrients, resulting in the disappearance or smallness of the crescent.
In fact, there is not enough theoretical basis for the relationship between the crescent moon and health, so if the body does not have special discomfort, it is not necessary to pay too much attention to these.
3. Growing older
As people continue to grow older, the speed of aging is also accelerating, and the rate of metabolism in the body will gradually slow down, so that the functions of the body will also slow down, and naturally affect the size of the crescent.
Is the more crescents on the nails the better?
Although the crescent moon is an intuitive response to human health, it is not absolute. The crescent moon generally grows at the end of the nail methyl, where the flesh is abundant, the crescent is easily obscured, and sometimes difficult to be seen by the naked eye.
Therefore, when people observe the crescent on the nail cover, there is no need to worry about seeing the situation without the crescent, perhaps it is not that there is some problem in the body, and the high probability is caused by flesh and blood.
In addition, the size of the crescent moon also has a certain relationship with the wear and tear of the nails. If you often borrow external forces to wear the nails, you can also stimulate the growth of the nails to a certain extent, and the faster the nails grow, the easier it is for the crescent to appear;
Conversely, the slower the nail grows, the easier it is for the crescent to be hidden. Therefore, friends who want the crescent moon to appear as soon as possible can try to wear their nails every day.
The size of the crescent is also closely related to age class and physical strength, and for the elderly or people with weak constitution, the crescent is relatively small and small.
It is difficult to see whether the body is healthy or not from the changes in the crescent on the nails alone, so the criteria for judging a person's health cannot be limited to the state of the crescent moon, but should also be combined with specific symptoms or related examinations.
