Are more crescents on your nails healthier? 5 kinds of changes in the nails, or the signal of disease

"How many teeth do you have? The less this means, the less healthy you are."

It seems like you have been told something similar since childhood. If I counted only 1-2 crescents on my hand, I would still feel very worried and feel that there is something wrong with my body. Is this really the case? What health information can nails tell us?

1. What does the crescent on the nail represent? How many are healthy?

Everyone's nails are composed of three parts: the nail plate, the skin around the nail, and the nail matrix. The nail plate is also the nail cover. The nail matrix is ​​the part below the nail plate that can produce new nails, and is generally invisible outside. The periungual skin refers to the part of the skin around the nail plate and the nail matrix. The periungual skin can protect the nail plate, and the nail can protect the fingertips.

The crescent on the nail, also known as a half-moon, is the real essence of the newly grown keratinocytes, which are white at first, and become translucent after keratinization, because the middle of the keratin grows the fastest. , a little slower on both sides, thus creating a kind of crescent shape.

Everyone has crescents on their nails, but the size of the crescents is related to natural differences and the frequency of finger use the day after tomorrow. Some people do not have crescents, it may be because the skin is in the way, the crescents grow slowly or start too far back.

Therefore, whether there are crescents or the size of the crescents, etc., has nothing to do with the health status, whether it is 2 crescents or 10 crescents. The key is to compare with yourself, if there is no change in size or number of crescents, such as sudden appearance or disappearance, it is generally normal.

However, nails do reflect the health status of the body to a certain extent, and factors such as diseases, nutritional status, changes in the environment and living habits will affect the shape and growth rate of the nails. So there are obvious changes, you should be careful.

2. There are 5 kinds of changes in the nails, you need to be vigilant

3. Other rumors about nails must also be recognized

1. Are long nails a lack of nutrients?

Many people have had the symptoms of long nails, mostly on the skin around the nail. Since the skin around the nail does not have hair follicles, sweat glands, and sebum, the moisture in the stratum corneum is easy to lose. When the skin around the nail is too dry, the epidermis and dermis will meet. Separation occurs, resulting in barbs.

This kind of barb is generally more common in people who do a lot of housework, work frequently, have nail art habits, and have a habit of biting nails. It has nothing to do with vitamin deficiency and poor spleen and stomach.

2. Vertical lines on the nails are anemia?

Most of them are caused by changes in the metabolic rate of the cells at the root of the nails. With the increase of age, the vertical lines on the nails will increase.

3. White spots on the nails mean there are worms in the stomach?

Fourth, take care of your nails, don't cut them blindly

After the nails are long, it is easy to hide dirt, so it is necessary to trim the nails regularly. If you want to take good care of the nails, you must choose the correct trimming method.

Nail clipping methods such as cutting too short, cutting into circles, and grinding the nails back and forth will cause great damage to the nails.

Cutting too short may expose soft tissue, increasing the risk of injury, and may also lead to ingrown nails.

Cutting your nails into round shapes is likely to cause ingrown nails and even paronychia.

· Grinding the nails back and forth will reduce the strength of the nails and not be able to better protect the fingers.

The correct way to trim nails should be divided into three steps . First, use alcohol cotton pads to sterilize the nails, grind the nails, and dry them. Secondly, soak the skin and nails of the hands and feet to soften it and make it easier to trim. When trimming, start from the middle and cut it flat, and don't cut it too short all at once. Lastly, moisturize with a hand cream.

The size and number of crescents on the nails have nothing to do with health. The key is to pay attention to whether there is any change. In addition, black lines, horizontal grooves, yellowing, thickening, shrinking, and white spots on the nails are likely to be the signals sent by the disease, and you should also pay attention to correct nail trimming.
