Does less crescent moon mean poor health? Here comes the answer, it can't tell the difference between good and bad!
There is an arc-shaped white mark under the fingernail. This mark is the nail half-moon mark, which is usually called the crescent. Almost everyone has crescents on their nails, but some people have more crescents, while others are so small that they are barely visible.
In daily life, there is a view that the crescents on the nails are related to physical health. "The more obvious the crescents, the better the health, and the fewer the crescents, the poorer the health."
Is this view correct? First, let's take a look at the formation of nails and see if it is related to the crescent moon.
- The methyl group is located at the bottom of the nail, which is the part where the nail is connected to the flesh. It is the key to the complete growth of the nail.
The methyl group will produce white keratin cells, which are the main substances that make up the nails. When these cells are produced, they will continue to grow upwards, and finally become hard and white, forming transparent nails.
- In fact, the crescent moon is newly grown, and the nails have not become transparent.
When the crescent moon is just produced, it will not turn transparent immediately, and the speed at which the methyl group secretes new nails is different. The growth rate of the middle of the nail is faster than that of the two sides. Showing a white curved crescent shape.
So, why are there more and less crescent moons? Does less crescent moon mean poor health?
The number of crescent moons is related to two reasons, the first is the methyl group, and the second is the metabolic rate of the human body.
Everyone has a methyl group on their nails, but its growth position is slightly different. Some people's methyl groups are closer to the upper part, so that the newly grown nails will be closer to the front, and the crescent moon will be larger and more obvious. And some people's new nails will be covered by the skin of the finger, and the crescent moon will look small.
- Everyone's metabolism is different. Some people have a fast metabolism, and the methyl group produces white keratin cells faster, so the crescent moon is numerous and clear.
Some people have a slower metabolism, such as the elderly, so the crescent moon will not be clear. Therefore, it can be seen from the above that the lack of crescent moon does not mean that the body is poor. This is mainly because the growth position of the methyl group is relatively backward.
With age, the body's metabolism will slow down, and the crescents on the nails will gradually become less obvious.
Although the crescent moon cannot distinguish the health of the body, it can also reflect some health problems. It is normal whether or not there are crescents, and the number of crescents.
However, if there are obvious changes in the crescent moon in a short period of time, such as the original crescent moon, which suddenly disappears, special vigilance is required in this situation.
It may indicate that the body has metabolic disorders, abnormal thyroid function, malnutrition and other problems. At this time, it is necessary to go to the hospital for examination and treatment as soon as possible.
In fact, in addition to the changes on the crescent moon, the changes in the nails can also reflect the health of the human body. If the nail color changes, black, purple, yellow, or vertical lines appear on the nail, it becomes uneven.
Most of these abnormal changes indicate that there is a problem with the body, such as neurasthenia and digestive system diseases, so people should also pay enough attention.
To sum up, the crescent moon is just a nail that has not finished growing, and the number of it does not indicate the quality of the body, so even if there is no crescent moon, you don't need to worry too much. In daily life, if there is a sudden change in the crescent or nails, you need to go to the hospital for inspection in time.
