About 90% of the body’s vitamin D production comes from sunlight. Our skin produces vitamin D3 by absorbing ultraviolet rays from the sun, and the body converts vitamin D3 into active vitamin D. This type of vitamin helps promote the absorption of calcium and phosphorus, as well as promotes the formation of bones, which is known as “sunshine vitamin”.
Sun exposure can prevent skin diseases, and the skin is properly exposed to ultraviolet rays, which can effectively kill the bacteria on the skin and increase the skin’s resistance to them. The sunlight can also enhance the body’s immune function and increase the phagocytic activity. The ultraviolet rays from the sun have a strong bactericidal ability. Generally speaking, bacteria and some viruses will be killed in the sun for half an hour or several hours.
Sunlight also plays a certain role in adjusting human body life rhythm and psychology. Sunbathing can promote the blood circulation of human body, enhance the ability of human body’s metabolism, and adjust central nervous system, thus making the human body feel comfortable. Not any time is good for soaking up in the sun. It is most suitable for us to bath from 6am and 10am in the morning. At this time, the infrared rays from the sun are intense and the ultraviolet rays are weak, which can play a role in promoting blood circulation. However, the summer sunshine is intense and the time is longer, so it is better to bask in half an hour accordingly.
There are so many benefits to sunbathing, but you should not overexposure to the sun. In general, people with fair skin can get sun exposure about 3-4 times a week for 10-20 minutes to meet the needs of human body manufacturing vitamin D. When the weather is hot, it can be done for 5-20 minutes each time. It is important to note that while the sun is good for physical and mental health, it is not recommended to spend two or three hours in the middle of a nearly naked exposure. Absorbing a small amount of sunlight makes people healthy and energetic, but too much sun exposure might cause skin disease even the risk of developing skin cancer.
We often like to wear shorts, t-shirts, skirts, bikinis, etc. This means that most of our skin is exposed to the sun, so we absorb more UV rays. The skin of head and face is the most vulnerable part and gets more time to sun exposure, so pay attention to protecting these areas. A sun protection hat can solve this problem. The purpose of the sun protection hat is protecting our skin by block the sun’s rays out of our head, face and neck from the sun. Sun protection hats mainly include wide-brimmed hats, bucket hats, and straw hats. The bucket hat is one of the most popular styles in recent years. It has rich design, various colors and different shapes. The hats of adults and children are not only different in size, but also the shape and pattern of the hats are quite different.
