A friend asked Huazi a question, the "small crescent" on the root of the fingernails, can it explain a person's health, the larger and more crescents, the better the physical health?
Huazi told a friend that traditional medicine has the saying that "the main tendon of the liver, its Hua is in the claw", if a person is in good physical condition and balanced nutrition, the nails will be ruddy and smooth, and the nails of each finger will have large and clear crescents. But according to modern medicine, the crescent on the nail has little to do with health.
First, the crescent on the nail is called "A half moon"
The nails of the human body are a layer of translucent cuticle plates covering the fingertips, which are composed of keratin produced by the mother of nails. Newly generated keratin is white and takes some time to become translucent. However, the speed of keratin production of motherplasm is different, the speed of intermediate production is fast, and gradually decreases to the edge, which will form a semi-arc-shaped white area, which is scientifically called "A half moon".
The first half moon is a newly generated nail, which will push the old nails from the past outward, growing about 0.1mm per day, growing faster in the summer and slower in the winter.
Second, why is there a large and a half moon
From the perspective of modern medicine, the factors affecting the number and size of the alpha half moon are related to the location of the nail matrix and the rate of keratin production, and there are great individual differences, mainly related to the genes of individuals, but have little to do with health. However, in the elderly, or those who are malnourished, the nail growth rate will decrease, and the nail and half month will become smaller.
A half month and the mobility of the hands are also related, usually work more people, nail growth is faster, A half month will also be larger, more, and usually less hands activity of people, nail growth is slower, A half month is also smaller.
Generally speaking, the thumb is used more daily, the nail grows faster, the nail half moon will be larger, and the little finger will be smaller. However, violinists, computer operators and other people who need to use the little finger often may also be larger, which is normal.
Third, is there a relationship between A and a half month and health?
Under normal conditions, the shape of the nail on the nails is different for everyone, just like everyone's appearance and body shape are different, and it has little to do with health. Only when there is a sudden change in the first half of the month can there be a health problem.
If an infection (such as nail fungus) occurs, or when there is a lack of nutrients or hypothyroidism, it can lead to slow nail growth, causing the nail to suddenly become smaller or disappear. If the nail and a half month suddenly becomes larger, it means that the metabolism becomes faster, and it is common in patients with hyperthyroidism.
The relationship between the vertical lines on the nails and health is not large, usually not obvious when young, more obvious after aging, the principle is the same as aging makes the skin wrinkles, not a health problem.
Patients with respiratory, lung disease, and cardiovascular disease, the tissue at the end of the finger is in a chronic hypoxic state, which may form a "clubbing finger", which will cause changes in the shape of the nail. If trauma is inflicted, it can cause the nails to appear uneven.
To sum up, the "small crescent" on the nail is called the nail half moon, and its number and size are mainly related to each person's own physique, and have little to do with health. Only when there is a sudden change in the first half of the month, it may mean that there is a health problem, and it is the best choice to see a doctor in time at this time.
