Is sun exposure really good for your skin?

Normally we say that proper sun exposure is actually effective in helping us kill bacteria and supplement calcium. However, many people may not know much about the benefits of sun exposure for the skin. Some people believe that as long as the skin is exposed to the sun, it will be exposed to ultraviolet rays, which will damage our skin, so try not to sunbathe. Now we want to analyze and introduce to you in detail whether sun exposure is good for the skin and what health benefits it has for the body.

Most people know that sunbathing for at least half an hour every day can promote calcium absorption, but not many can explain why. In fact, the most important factor affecting human calcium absorption is the metabolite of active vitamin D. Vitamin D is obtained mainly through two ways. One is from food, and the other is to synthesize vitamin D3 after the ultraviolet rays in sunlight irradiate the human skin. It can promote the absorption of calcium in the small intestine and even in the colon. If the human body lacks vitamin D, the calcium absorption rate is only 10%; if the body contains enough vitamin D, the calcium absorption rate will increase to 60%-75%.

Vitamin D is also called the "sunshine vitamin". The vitamin D3 source contained in human skin is produced and converted into vitamin D by absorbing ultraviolet rays in the sun. It can help the human body take in and absorb calcium and phosphorus. A person who never sees sunlight will have a much higher incidence of osteoporosis than the normal population.

ASunlight can accelerate metabolism. Sunlight exposure can promote blood circulation in the human skin, accelerate skin metabolism, and regulate the body's immune function. For patients with psoriasis and rheumatoid arthritis, getting more sun exposure will have a good auxiliary therapeutic effect. Sunlight can also promote the production of melanin in the skin and enhance the skin's resistance to ultraviolet rays. Therefore, to a certain extent, the skin is an important organ in the human body that affects calcium absorption.

Therefore, sunbathing is very good for the body. BSunshine can also make people happy. Sunlight exposure can change the content of certain signal substances in the human brain, making people feel excited and willing to engage in challenging activities. Sunbathing for half an hour in the morning is particularly effective for people who are listless and depressed. Sunbathing also has a certain effect on treating seasonal affective disorder.

The sunbathing mentioned here does not mean directly exposing yourself to the sun, but walking in the sun from time to time on sunny days in your life. This can reduce direct exposure to ultraviolet rays, maximize the effectiveness of the sun, and avoid adverse effects. Therefore, you must use the correct method to sunbathe.
