How much do you know about health?
In our daily life, we often notice that our fingernails have different crescent shapes. So, why do some nails have crescents and others don't?
First of all, we need to understand the structure and growth process of nails. Nails are produced by a methyl tissue that is located below the base of the nail and is the main base for making nails. In methyl groups, keratin cells are constantly growing, dying, and keratinizing, eventually forming our nails. The crescent moon is actually a white crescent-like structure formed by the new keratin cells pushing the previous generation of keratin cells outward.
However, why do some nails have crescents and others don't? This is actually related to the individual's genes and the growth rate of the nails. Some people, due to the influence of genes, are born with methyl groups that grow relatively backward and are blocked by the ** of the fingers, so it is difficult to see the crescent. In addition, the growth rate of the nail also affects the size of the crescent. When the nail grows faster, the new keratin cells are pushed out earlier, so the crescent moon will be more noticeable; Conversely, when the nail grows slowly, when the new nail grows out, the keratin cells have died and become hyaline, and it is difficult for us to see the crescent.
As we age, our body develops at a slower rate and the growth rate of our nails slows down, so the crescent moon gradually becomes smaller or even disappears. This does not mean that there is a problem with our health. In fact, the number and size of crescents are not indicative of a person's health. Some conditions do cause changes in the crescent, but this is not judged by looking at the crescent. For example, an abnormality in the thyroid gland may cause a dramatic change in the rate at which cells proliferate, affecting the size and appearance of a crescent. However, this condition is relatively rare, and most people's crescent changes are not directly related to their health status.
Therefore, we should be rational about the existence and changes of the crescent moon. Don't believe in claims that are not supported by science, such as "the more crescents, the better", "the fewer crescents, the less healthy", etc. Everyone's physical condition and nail growth are different, so the number and size of crescents will also vary. We should focus on our overall health and not just the crescent moon on our fingernails.
