Why do fingernails have no blood and turn dark purple?

The dark purple color of fingernails may be caused by the following reasons.

Purple fingernails may be caused by lack of oxygen. When our body doesn't get enough oxygen, the oxygen content in our blood decreases, which causes fingernails to turn dark purple. This usually occurs in people who live at high altitudes or who are exposed to cold conditions for long periods of time. Certain respiratory diseases can also cause hypoxia, such as chronic obstructive pulmonary disease.

Purple fingernails may also be caused by poor blood circulation. When our blood vessels are constricted or blocked, blood cannot flow adequately to our fingernails, causing them to darken. This phenomenon is especially noticeable in cold weather, because cold causes blood vessels to constrict. Other circulatory problems such as heart disease and arteriosclerosis may also cause poor blood circulation.

Purple fingernails may also be caused by trauma or infection. If our fingernails are injured or infected with bacteria, it will cause inflammation and blood pooling, causing the fingernails to turn black or purple. In this case, timely treatment and treatment are very important.

To improve the problem of dark purple fingernails without blood, we can take the following measures:

Maintain adequate oxygen supply. People who engage in regular outdoor activities, especially those who live at high altitudes, should pay more attention. It is also important to maintain indoor air circulation.

Improve blood circulation. You can promote blood circulation by massaging your fingernails, warming your hands, and avoiding prolonged exposure to cold environments. If there are blood circulation problems, it is recommended to seek medical treatment promptly.

Pay attention to the hygiene and health of your fingernails. Keep your fingernails dry and clean, and treat any trauma or infection promptly. Using hand cream is also a good option, as it moisturizes the skin on your hands and improves blood circulation.

Fingernails that are bloodless and dark purple may be caused by lack of oxygen, poor blood circulation, trauma or infection. In order to improve this situation, we should pay attention to maintaining adequate oxygen supply, improving blood circulation, and keeping fingernails hygienic and healthy. In this process, the best effect is to use moisturizing hand cream, which can provide sufficient moisture and protection for the hands and is affordable.
