Talk about the benefits of sunbathing to human health

Speaking of sunbathing, I believe many people often take their children outside to sunbathe. Frequent exposure to ultraviolet rays, although not very good for the skin, occasional exposure can supplement calcium and vitamin D. Frequent sunbathing can also treat cartilage disease, rickets and osteoporosis problems, so everyone can go out to sunbathe often.

90% of the vitamin D needed by the human body must be obtained through sun exposure. The skin produces vitamin D3 by absorbing ultraviolet rays from the sun, and the body then converts vitamin D3 into active vitamin D. This type of vitamin helps promote the absorption of calcium and phosphorus and promotes bone formation, which is why vitamin D is called the "sunshine vitamin."

1. Sunbathing can delay aging.

Studies show that people with higher vitamin D levels in their bodies are about 5 years younger on average than those with lower vitamin D levels.

It can help the human body take in and absorb calcium and phosphorus, making children's bones grow strong and healthy. It has a preventive effect on infantile rickets and osteomalacia. For adults, it can prevent osteoporosis, rheumatoid arthritis, etc.

3. Sunbathing can prevent skin diseases.

Proper exposure of the skin to ultraviolet rays can effectively kill bacteria on the skin and increase the skin's resistance.

4. Sunbathing can also enhance the body's immune function and increase the activity of phagocytes.

The ultraviolet rays in sunlight have strong bactericidal ability. Generally, bacteria and certain viruses will be killed after being exposed to sunlight for half an hour or several hours.

Sunbathing can promote blood circulation, enhance metabolism, and regulate the central nervous system, making the body feel relaxed and comfortable.

6. Sunbathing can increase men's testosterone levels, enhance sexual desire and improve sperm quality.

Because the level of testosterone in the human blood will increase with the increase of vitamin D content in the body. The study also confirmed that one hour of sun exposure every day can increase the testosterone in the human body by 69%.

7. Prevent anemia.

Because the ultraviolet rays in sunlight can also stimulate the bone marrow to produce red blood cells, improve hematopoietic function, and thus prevent anemia.
