What are the benefits of sunbathing? Many people like to sunbathe and do it all the time, but many people don't understand the phenomenon of sunbathing. They think that sunbathing is very harmful to the body because the sun is a kind of ultraviolet light, and ultraviolet light can burn your skin. Many people are worried that their skin will be tanned after being exposed to ultraviolet light, so they are unwilling to sunbathe. So what are the benefits of sunbathing?

Sunbathing can delay aging, and vitamin D plays a role in this. 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. 90% of the vitamin D needed by the human body must be obtained through sun exposure. It can help the human body to ingest and absorb calcium and phosphorus, and has a preventive effect on infantile rickets and osteoporosis, as well as rheumatoid arthritis in adults. In addition, sun exposure 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. 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. Sunlight also plays a certain role in regulating the human body's life rhythm and psychology.

Sunbathing can promote blood circulation, enhance metabolism, and regulate the central nervous system, making the body feel relaxed and comfortable. Sunbathing can increase men's testosterone levels, enhance sexual desire and improve sperm quality. The ultraviolet rays in sunlight can also stimulate the bone marrow to produce red blood cells, improve hematopoietic function, and thus prevent anemia.

If we get more sun exposure, we can get these benefits. Sun exposure can also supplement calcium. If your body is calcium deficient, you can improve it by sun exposure. Sun exposure can also strengthen your physical fitness and delay aging. However, it is important to sunbathe early and late, and avoid excessive exposure, which will cause sunburn.
