However, no crescent moon does not mean unhealthy. Whether you are healthy or not, you can't know until you go to the hospital for examination.
Learn what a crescent moon is first.
The crescent moon on the nail, professionally called Jiabanyue, belongs to a physiological structure. It is a newly produced keratin cell. If the white arc just comes out, it is half moon, which is what we call crescent moon.
Why is the crescent moon just a healthy reference? In fact, the reason is very simple, just like a newborn child without a crescent moon. As he grew up, a crescent moon appeared on his nails. Moreover, some people have late methyl or slow nail growth, most of which are natural and healthy, and it is not uncommon around us.
Next, I will talk about the crescent moon from the perspective of Chinese medicine and western medicine.
The reason why the crescent moon can be used as a reference for human health is from the perspective of Chinese medicine: Chinese medicine commonly calls the crescent moon "little sun", and they think the crescent moon is a window reflecting energy and vitality. If the crescent moon on a person's fingernail has a large radian and a good luster, it means that the blood is abundant; If the crescent moon becomes smaller or gradually disappears, it means that the qi and blood are declining and the physical condition is not as good as before.
Moreover, it is indeed recorded in Chinese medicine that human heart function can be judged by Baiyue. Traditional Chinese medicine believes that the liver stores blood, and the quality of blood circulation directly affects the heart and is also concentrated on the nails. An energetic person has about 8~ 10 crescent nails. The more crescent moons, the healthier. If the little finger has crescent nails, it means that he is very energetic. However, the area of the crescent is not as wide as possible. If it is too wide, it is easy to get high blood pressure. The width of a normal crescent moon accounts for about one-fifth of the nail.
So in Chinese medicine, we can know whether a person is healthy by observing his nails, especially his internal organs. Therefore, they think that the crescent moon is a "barometer" to judge whether a person is healthy with the naked eye.
Western medicine believes that crescent moon has nothing to do with health, but a phenomenon in the process of nail growth. But western medicine knows that people who are already very heavy are malnourished and particularly thin. At this point, some patients will have nail growth stagnation, that is, the crescent moon has changed.
In other words, after people get sick, the crescent of nails does change, and it suddenly becomes bigger or disappears, which is also because of the change of illness, which ultimately affects the growth of nails. But in this case, is it necessary to look at the changes in nails? ! I have been seriously ill, which is the result of slow nail growth caused by serious illness.
Just like a person with hyperthyroidism, if his metabolism becomes faster, his nails will grow faster and the crescent moon will grow bigger and bigger. On the contrary, people with hypothyroidism have slow metabolism, slow nail growth and no new keratin cells, so the crescent moon is getting smaller and smaller, or disappears.
There are also people who don't often work and do housework in life. Their nails grow slowly and they can't even see the crescent moon clearly. If you don't believe me, go home and look at the people who work the least at home. Their nails are usually the smallest crescent. Look at your fingers again. The crescent moon of thumb is bigger, but the smallest one is the little one? In fact, this is also related to the degree of nail wear and the frequency of finger use.
The thumb and the other four fingers do most of the work, so the nails wear out quickly and naturally grow fast, and the crescent moon is easy to be pushed out. The little finger is rarely used, and the crescent moon is much smaller and even invisible.
Speaking of which, some netizens will ask, then why is my little finger crescent big? Explain that you may be engaged in a lot of work that needs to be done by your little finger, such as playing the piano and being a programmer.
In short, whether from the perspective of traditional Chinese medicine or western medicine, we should pay attention to exercise at ordinary times and spare 30 minutes for aerobic exercise every day. Balance nutrition and eat less junk food. Stay up as little as possible. If you get enough sleep, you will be full of energy.
