Nails grow hard because of high calcium content? The answer is no, it is found that the calcium content in nails is very low, accounting for only about 0. 1% of its weight. In fact, it is the high sulfhydryl protein in nail keratin that determines their hardness. In addition, the moisture content of nails is less than that of skin, which is also a reason for its greater hardness. Strong nails protect the skin under the nails.

Nails grow every day. Interestingly, the growth rate of different parts of nails is different. The nails of the right hand grow faster than those of the left hand; Toenails grow slower than fingernails, and the growth rate is about 1/3 ~ 1/2 of fingernails. The nails of the same hand grow at different rates. Generally, the longer the finger, the faster the nail grows. The order from fast to slow is middle finger, index finger, ring finger, thumb and little finger.

The reason why nails grow fast.

Excessive qi and blood in the body

When a person's nails grow too fast, it actually means that the blood in the human body is too strong. This kind of person often belongs to the grumpy type, because too much blood will lead to a person's heart is very dry, so he often can't restrain his emotions and has to show it.

There are too many plants at home.

In fact, the reason why a person's nails grow so fast is sometimes related to the environment in which this person lives. If a person lives in a place where there are many feng shui plants, it is easy to cause the smell of these plants to affect people, which naturally leads to his hair and nails growing faster and faster.

Sleep too long

Although a person who doesn't sleep will affect his health, sleeping for too long is actually bad, because such a situation can easily lead to too much breath secretion in his body when he sleeps, which will naturally lead to the rapid growth of nails, but it is actually very harmful to his body.

Too much breath in the body

Although many times too much breath in a person's body is harmful to his health, sometimes too much breath is also harmful. If a person's nails grow too fast, in fact, it may be because there is too much breath in the body, so that it leaks out, which leads to their nails growing very fast.

Excessive yin in the body

When a person has too much yin in his body, it will actually lead to the rapid growth of his nails. Moreover, the nails that grow because of yin qi are usually of poor quality, some will be black, and some will even make people feel like bark, because these nails usually look shabby and unsightly.

In fact, sometimes it's not a big deal that nails grow too fast. You only need to adjust the feng shui at home to get a better change, and sometimes you can adjust the breath in your body to prevent other things that are not good for you.
