When most people extend their fingers to look at the nails, they will see that there is an area at the base of the nail that is white in color and looks like a crescent moon. Clinically, this "crescent" is also known as a half-moon mark.
It is a newly produced keratin cell in the fingernails, and because it has just been produced, it produces a little whiter than the outer pink nails. Over time, new keratin cells age, making the nails long and the color of most nails.
The crescent moon is just the keratin cells grown by the fingers, because these keratin cells are softer in texture and push the old cells that have grown before to grow outwards, and these old cells will become harder and harder, and the nails will grow longer and longer.
There are scientific studies, people who usually trim their nails often have more crescents, and if they do not trim their nails for a long time, the amount of crescents is also smaller. In addition, the growth of the crescent moon is related to the nutrition that the human body usually consumes, the environment everywhere and the health of the body.
Therefore, when some doctors see people, they will also observe the situation of the hands and nails. However, what exactly does the number of crescents have to do with health?
It is clinically proven that the crescent, whether it is more or less, will not affect health, but it also has a certain relationship with health. For example, certain conditions in the body will affect the body's metabolism, so that the metabolism and growth of keratin are abnormal, and the number of crescents changes.
Therefore, some doctors will help determine the condition by looking at the crescent of the finger. Here's how you can tell you, the following four situations may affect the crescent.
1. Excessive liver fire will increase the number of crescents
If the crescent moon has suddenly become larger recently, it may be caused by excessive liver fire. Because the liver undertakes metabolic and detoxification functions in the human body, if the liver fire is too exuberant, its function will be weakened.
When the body's metabolism rate slows down, the production rate of keratin cells will also slow down, so the area of the crescent may increase as a result.
2. Excessive fluctuations in blood pressure in the elderly will increase the number of crescents
The body function of the elderly is weaker than when they were young, and their metabolic capacity will also decline, if the blood pressure is unstable, it will also be found that the crescent of the finger becomes larger, and the blood pressure must be adjusted in time to avoid more cardiovascular damage.
3. Hyperthyroidism will increase the number of crescent teeth
Hyperthyroidism is hyperthyroidism, a disease that causes the body's metabolism to speed up and the faster the nails to grow. The new nails have not yet faded into a translucent color, the hardness is not enough, and the crescent of the nails is easy to become larger.
4, physical weakness will make the crescent less and less
The body suffers from more serious diseases that will cause the patient's body to be unable to digest and absorb food normally, and in the case of malnutrition and emaciation, the growth rate of nails will become slower and slower, and the number of crescents will become less and less.
The number of crescents may be related to the above four conditions, so you can usually observe the crescent on the nails, and then judge the health status according to the symptoms you are showing. If the body has already experienced symptoms of discomfort, it is necessary to go to the hospital for relevant examinations to determine the cause of physical discomfort and crescent abnormalities and then symptomatic treatment.
