Now there's a saying: "the only good thing about sun exposure is that it promotes vitamin D synthesis, and everything else is bad. We get vitamin D through food, so we don't need any sun at all." Actually this saying is one-sided, although the ultraviolet ray in the sun really can let the skin aging, turning black, wrinkles, and even illness into skin cancer, and we can get vitamin D from yeast, mushrooms, and animal food, such as animal liver, egg yolk, cream, cheese and fish and eggs, but the sun does not only promote the synthesis of vitamin D, the benefits of the sun improve the nervous system, endocrine, digestion, circulation, respiration, blood, the function of the immune system. And people rarely go out of their way to choose foods that are rich in vitamin D, so sunlight is still the most important source of vitamin D compared to food. Sun exposure 2 ~ 3 times a week, 15 ~ 30 minutes each time, can rapidly increase the concentration of vitamin D in the body.

When in the sun had better wear red clothing, next choose white clothing, avoid wearing black. However, it should be noted that the sun shine through the glass is not effective. Get at least 30 to 60 minutes of sunlight a day to balance the Yin and Yang. Excessive sun exposure won't cause vitamin D poisoning, but it will make your skin darker.
There are two periods of the day that are most suitable for sun exposure:the first period is 6 to 10 AM, and the second period is 4-6 PM, but no matter what season between 10 am and 4 PM, do not expose to sun in long time, otherwise it will cause damage to the skin.
