Crescents and vertical lines on nails are common nail features, but they are not necessarily directly related to physical health. Below we will take an in-depth look at the crescent and vertical lines on the nails and explain their causes and relationship to health.
First, let's explore why some people have a crescent moon on their nails and others don't. The crescent is a white, curved area on the nail bed, usually located near the fingertips. They are formed by newly grown keratin cells that gradually appear as the nail grows. However, not everyone can see a noticeable crescent on their nails. The appearance of the crescent moon is related to the rate of an individual's metabolism, as well as the rate of nail growth. Older people have a slower metabolism, so the number of crescents may be relatively small or even none. Conversely, children have a faster metabolism, so they usually have a higher number of crescents. In addition, an individual's genetic factors may also play a role in the appearance of the crescent.
However, the crescent moon on the nail does not directly reflect a person's physical condition. The so-called "the more crescents on a person's nails, the healthier the body" has no scientific basis. In fact, there is no direct correlation between the number of crescents on the nails and physical health. The health of the human body is a comprehensive problem that cannot be judged simply by looking at the crescent moon on the nail. Physical health is affected by many factors, including diet, lifestyle habits, genetics, etc., and does not only depend on the appearance of the nails.
In addition to the crescent, some people may have noticeable vertical lines on their nails. These vertical lines are usually caused by age, dry nails, external irritants, or other factors. The appearance of vertical lines does not necessarily indicate a health problem. However, in some cases, vertical lines on the nails may be associated with health conditions such as malnutrition, dehydration, certain diseases (such as heart disease, diabetes), and side effects of some medications. If you are concerned about the vertical lines on your nails, you can consult your doctor for further testing.
In summary, crescents and vertical lines on nails cannot simply be used to judge physical health. The appearance of crescent moons is related to an individual's metabolic rate, nail growth rate, and the appearance of vertical lines can be related to a variety of factors. If you are concerned about the characteristics of your nails, it is recommended to consult a doctor for professional evaluation and advice. Remember, maintaining a healthy lifestyle and regular check-ups is the most important thing, not just judging your health by the appearance of your nails.
