Healthy nails are smooth, without convex or concave stripes. They are even in color and density, generally slightly redder than the skin, showing a slight ruddy appearance. In addition, there should be no spots or discoloration on the nails. The semilunar nail arc at the bottom of the nail cover has nothing to do with health.
Tip: Research shows that the healthiest nail aspect ratio should be 4: 3.
Don't be alarmed if the following situations occur, because these changes do not indicate health problems, such as vertical stripes, white lines or spots. With the increase of age, the vertical stripes on nails may become more and more obvious. Spots are usually caused by injuries to fingernails or nail beds.
However, some situations may indicate disease. For example, yellow nails may indicate respiratory problems, such as chronic bronchitis, or swollen palms (lymphedema) and nail infections. Purple nails often indicate poor peripheral circulation or heart and lung diseases. Horizontal lines appear on the nails because the growth of the area below the epidermis is blocked. This situation may occur during trauma or serious illness. If nails fall off, it is often caused by psoriasis or adverse drug reactions. If you have abnormal nails for a long time, you'd better go to the hospital for examination so as to find health problems early.

Proportional shape luster color texture
1, the proportion of nails
The shape of nails mainly includes the length-width ratio of nails and the shape of nails. Because the shape of nails is mostly related to congenital genetic factors, most of them are physical differences.
Dragon: People with long nails are gentle and not impatient, so diseases caused by mental factors are rare in them. However, due to weak innate constitution and poor immune system, it is easy to suffer from acute inflammatory diseases, such as upper respiratory tract infection, gastroenteritis, brain and chest diseases and so on.
Short stature: people with short nails belong to a personality that is easy to be impatient and impulsive. This kind of people's heart function is relatively weak, and they are prone to diseases from abdomen to waist, as well as legs and feet. If the nail tip is flat and embedded in the meat, it is more prone to diseases such as neuralgia and rheumatism.
Square: The length and width of this nail are close to a square. This kind of human body is relatively poor and often belongs to the type of weak constitution. Although there are no obvious serious diseases, they can easily become patients with many genetic diseases. If women have such nails, they should be alert to problems in the uterus and ovaries.
Tip: The healthiest nail aspect ratio should be 4: 3.
2. The shape of nails
Lily-shaped: nails are long, with obvious protrusions in the middle and curved around, shaped like lily slices. This kind of nail is more common in women and the shape is the most beautiful. However, people with this kind of nails are mostly weak and sick from childhood, especially the digestive system, which is prone to blood system diseases.
Fan-shaped: this kind of nail is narrow under the nail and wide on the top, and the fingertips are curved. Most people with fan-shaped nails are born with strong physique. They have good physical fitness and strong endurance since childhood, but they tend to ignore their health. Adults or the elderly are prone to duodenal ulcer, cholecystitis and even liver disease.
Round: round nails, the owner looks strong and rarely gets sick. This kind of person is very insensitive to diseases, and it is difficult to realize the abnormal condition of his body. So once they get sick, they are often very serious. Ulcer bleeding, pancreatitis, cardiac insufficiency and even cancer are most likely to happen to them.
Step 3: Smooth nails
One color is about the luster and color of nails. Healthy people's nails have a certain luster, which is relatively uniform, like a piece of smooth glass, and should be beautiful pink.
Once the nail color changes, it means that something has happened in some parts of the body and should be paid attention to.
Jiaze lights up:
There are two kinds of brightening of Jiaze. One is that there are blocks or strips on the nails, not the whole nail, which are mostly related to pleurisy and abdominal ascites; In addition, the whole nail is as bright as oil, and the nail becomes thinner, which is more common in patients with hyperthyroidism, diabetes and acute infectious diseases.
Uneven gloss:
Uneven nail gloss can be manifested in different nails or in different parts of the same nail. If the front end of each nail is shiny and the root is dull, there may be chronic bronchitis and cholecystitis; If only some nails are uneven in luster, it suggests that there are some chronic injuries and inflammation in the body.
Lose luster:
If the whole nail is like ground glass, it has no luster at all, indicating that there are some chronic wasting diseases in the body, such as tuberculosis; This can also happen to patients with serious wasting diseases, such as liver abscess, lung abscess or long-term chronic bleeding.
4. Color of nails
One color is white:
Pale nails and lack of blood color are more common in patients with malnutrition and anemia; In addition, if the nails suddenly turn white, it is common to have emergencies such as blood loss and shock, or chronic diseases such as hookworm disease, gastrointestinal bleeding, advanced tuberculosis and cor pulmonale. It should be noted that if the nails are as white as ground glass, it is a feature of cirrhosis.
Color turns gray:
Nails are gray, mostly due to lack of oxygen, more common in smokers; For non-smokers, nails suddenly turn gray, most likely suffering from onychomycosis. At first, the edge of the nail will itch, and then the nail will lose its luster and turn gray, such as onychomycosis.
Color turns yellow:
Yellow nails are mostly caused by damp-heat fumigation, which is common in hypothyroidism, carrot disease and nephrotic syndrome. Western medicine believes that yellow nails are mostly related to the lack of vitamin E in the body. If all nails turn yellow, they must be treated, because it is a symbol of general weakness.
5, nail texture
Concave nail refers to some horizontal stripes, vertical stripes and spots on the nail. Traditional Chinese medicine points out that this change of nails is closely related to pathological changes such as low function of tissues and organs, destruction and atrophy of tissue structure.
Vertical stripes:
The nail surface is not smooth enough, and a straight line appears, which generally appears after overwork and excessive brain use; These vertical stripes will appear obviously in the case of insufficient sleep. If vertical stripes persist, it may be a chronic disease of internal organs. If not nursed back to health, with the development of the disease, nails will become uneven and even crack.
Horizontal stripes:
The tattoo on the nail is a record of the lesion that has occurred. In other words, when there are horizontal lines on the nails, there must be some lesions in the body. Generally speaking, at the beginning, the stripes are only at the bottom of the nails. With the growth of nails, it gradually moves upward, indicating that the onset time is getting closer and closer.
Spots:
There are a few white spots on the nails, which are usually manifestations of calcium deficiency, silicon deficiency or parasitic diseases; There are many white spots, which may be a sign of neurasthenia; Yellow spots on nails may cause diseases of the digestive system; If there are black spots on your nails, be careful. The light one is just overwork and malnutrition, and the heavy one may be a precursor of gastroptosis, gastric cancer and uterine cancer.
