Different parts of the body can reflect whether the body is healthy or not. Take the hands for example. If abnormal symptoms such as palmar erythema or spider angiomas appear, it means that the liver function is not good.

Some people say that the lunulae on fingernails can reflect physical health, and the more lunulae, the better. Is this really true?

1. What are the lunulae (half-moons) on fingernails? Are more of them healthier?

Everyone has lunulae on their fingernails, some big, some small, some many, some few. So what is the relationship between lunulae and physical health?

The lunula, also known as the nail half-moon or half-moon mark, actually refers to the white crescent-shaped area on the nail .

Human nails grow from the nail bed and then slowly push outwards. Initially, they are white and then become transparent. Therefore, the lunula (half-moon shape) is actually part of the nail that has not become transparent.

The size and number of lunulae on fingernails have nothing to do with physical health. Most people have relatively obvious lunulae on their thumbs, which is related to the high frequency of thumb use . Even if some people cannot see lunulae on their fingernails, it does not mean that they do not have lunulae.

2. Does the appearance of white spots on fingernails indicate a calcium deficiency?

Some people find white spots appearing on their nails for no apparent reason and assume it's due to calcium deficiency.

Actually, white spots on fingernails are not caused by calcium deficiency. Experts say that most white spots on fingernails are caused by bumps or injuries. These white spots will not affect your health, do not require special treatment, and will gradually disappear as the nail grows.

However, some white spots may also be caused by malnutrition or gastrointestinal problems, especially if accompanied by other symptoms such as fatigue and nausea . In such cases, it is necessary to seek medical attention as soon as possible for further examination.

III. These abnormal nail conditions may indicate underlying health issues.

While lunulae and white spots on fingernails are generally not related to health, some abnormalities on the nails may be signals of disease, so it is important to be vigilant.

1. Black-spotted nails

If you notice black vertical lines on your nails or blackening at the junction of your nail and skin, and these blackening and growth patterns are present, be wary as they could be signs of melanoma and require prompt investigation and treatment.

2. Horizontal striped nails

Horizontal ridges on the nails can be a signal of internal health problems, especially those that move upwards. People with many fine horizontal ridges on their nails are more likely to have chronic digestive system diseases.

3. Vertical striped nails

Normal nails should be smooth and flat. If you find vertical lines on your nails, be careful as it may be a sign of neurasthenia or other conditions. You should adjust your condition as soon as possible and seek medical attention.

4. White spots on fingernails

Besides white spots caused by external forces, long-term malnutrition, anemia, gastrointestinal abnormalities, etc., may also cause white spots on the nails.

To maintain good nail health, it is recommended to eat more blood-nourishing foods, ensure a balanced intake of meat, eggs, dairy products, and other foods, and do more hand exercises to promote blood circulation in the hands.

Do you think the more lunulae (half-moons) on your nails, the better? Actually, no. Lunulae on nails are not closely related to health. If you find black spots, horizontal lines, vertical lines, or white spots on your nails, it may be a signal of an underlying health problem and you should get checked as soon as possible.
