Why do nails turn purple

The weather is very cold and the human body is frozen, which hinders the blood circulation in the body. The lack of blood circulation causes the nails to appear blue and purple. However, not all purple nails are caused by this. It may also be because there are certain problems in the human body, which leads to poor circulation and blood blockage, causing purple nails. Therefore, this problem must be handled correctly.

Why do fingernails turn purple?

1. Why do fingernails turn purple?

First of all, we should suspect the arrival of disease, because the symptoms of certain diseases are manifested on the fingernails. Purple fingernails may also be caused by nutritional deficiencies or trauma. Therefore, the patients themselves should observe and analyze the reasons in detail. If necessary, choose to go to a regular hospital for examination. Experts point out that purple fingernails may have the following reasons: abnormal heart and lung function. If there is congestion, the temperature will increase and the blood circulation will accelerate, and the color will naturally return to its original color.

The top of the human limbs, that is, the toes and handtips are far away from the heart and have a weaker blood supply. In winter, when the heat in the fingertips is lost, the blood cannot supply the heat quickly, so the temperature of the fingertips will be low, the capillaries will contract, the blood flow will be poor, the venous blood cannot return immediately, and the arterial blood cannot be supplied immediately, the nails will turn purple, and in severe cases, frostbite will occur. Pay attention to check whether there is any abnormality in hemoglobin.

2. There are brown vertical lines on the fingernails

If brown vertical lines or cracks appear on the surface of the nails, extending from the fingertips to the base of the nails, it indicates intestinal inflammation or indicates vitamin deficiency and iron deficiency. Whitening of the nails indicates zinc deficiency. General paleness indicates anemia. Brown-yellow stripes on the nails are a sign of liver disease. However, we should note that the brown-yellow streaks that appear on ten nails at the same time are a sign of liver disease, and appear only on the basis of diagnosis and not on one.

3. Dark red and purple blood spots on fingernails

Dark red and purple blood spots seen under the nails often indicate epilepsy, blood disease, etc. The appearance of pinpoint-sized depressions on the nails is medically considered to be a manifestation of a sub-healthy state on the nails. The bumps and unevenness of nails are mainly caused by the lack of vitamin A and calcium in the human body. You should eat a certain amount of carrots, egg yolks and other foods on a regular basis. People with thimble nails are one of the prominent manifestations of the lack of necessary trace elements and calcium in the human body. At the same time, they may also be accompanied by hair loss, dry skin of the lips, etc.

What is the common sense of nails?

1. Nails are a window to your health.

Some doctors can roughly judge a person's health status just by looking at his or her nails: blue color may indicate lung disease; the presence of capillaries in the stratum corneum may indicate an autoimmune disease, etc. If your nails appear abnormal, seek medical attention immediately.

2. White spots on the nails do not indicate calcium deficiency.

White spots are common, harmless, and do not indicate a deficiency in any specific element in the body. White spots are likely marks left on the nail plate (or nail matrix) from previous trauma.

3. Nails and hair are made of protein.

Nails and hair are both made of keratin, just in different combinations. This means that foods that are good for hair health are also good for nails, such as vitamins, protein, etc. People also need to consume healthy oils and fats to keep their hair and nails moisturized.

How to judge your health from your nails

Few half-moon marks

Many people will find that there are very few or even no half-moon marks on their fingers for a period of time. In fact, this means that you need to have a good rest, because this is because the body is overdrawn and the energy has deteriorated. If you can get a good rest, the half-moon marks will return to normal after a while.

In addition, some friends will find that their half-moon marks have always been very few and do not suddenly decrease within a certain period of time. In fact, this is because of their weak constitution and weak immunity. Friends with this condition often have cold hands and feet, so these friends need to improve their immunity and eliminate cold and dampness in the body so that the half-moon marks can return to normal.

This situation is also called "cold type" in traditional Chinese medicine, which means that the fewer half-moon marks there are, the colder the constitution is. Therefore, such friends should pay attention to changing their cold constitution in life.

The half-moon mark is very large

People with a large area of ​​half-moon marks, even one-third of the upper part of the little finger, are called "hot base type". People with this kind of half-moon marks have strong yang energy in the body, strong organ functions, and top physical fitness.

But there is one thing that needs to be noted, because the yang energy in the body is very strong and the blood circulation is very fast, it is easy to have high blood pressure and other conditions, and such friends often have bad taste, irritability, and constipation due to the hyperfunction of the internal organs. Therefore, we need to pay more attention in life to avoid these situations that may cause damage to our health.

Blurred borders of the half-moon mark

Friends who have blurred boundaries of the half-moon marks and who slowly turn into the same color as the nails need to be careful, because this is often a sign of a "cold and hot alternating" constitution.
