Winter is the season for respiratory diseases such as colds and flu, and the ultraviolet rays in the sun are a "natural disinfectant" that kills a variety of viruses and bacteria to help prevent diseases.

Exposure to solar energy helps the body obtain vitamin D, which is one of the important sources of vitamin D in the human body, which can help the body promote the absorption and utilization of calcium and phosphorus, help you prevent osteoporosis, and make your bones stronger.
Secondly, vitamin D deficiency can increase the risk of type 2 diabetes, and sun exposure can increase the level of vitamin D in the body and play a role in regulating blood sugar.

In the bright outdoors, the muscles used in the usual near use of the eyes will also relax, so that the eyes can be rested, and the occurrence and development of myopia can also be alleviated, so increasing outdoor exercise is also one of the effective means to prevent myopia in children and adolescents.
Secondly, sun exposure can stimulate the release of dopamine in the eye, which has a positive effect on vision.

Sunbathing Tip 1: "The Law of Shadows"
The most suitable time to bask in the sun in winter is 9:00~11:00 and 15:00~16:00, the sun is weak in winter, if the sun is not very strong in the afternoon, it is also a good choice to take a walk after 1 hour after lunch.
Recommend a "shadow law"
If you want to find a good time to bask in the sun during the day, looking at the length of the shadow is a good way:
▶ When your shadow is 2 times your height, or even longer, the UV index is safer, and you don't need protection, so you can get a good sun;
▶ When the shadow is in the range of 1~2 times the height length, it is safer to control the sun exposure time to about 20 minutes;
▶ When the shadow is shorter than the height, UV rays may cause damage to the skin within 30 minutes;
▶ If the shadow is less than half the length of your height, UV rays can damage the skin within 15 minutes.
Generally speaking, most people can meet the body's needs by basking in the sun for 20 minutes a day, and the time for children is shorter, and the elderly are longer, but it is generally recommended to control it within 30 minutes.
People living at high altitude and long-term hypoxia environment, because hypoxia will aggravate bone loss, need to extend the sun exposure time to 30~60 minutes a day, but do a good job of sun protection.
