The winter sunshine is warm and makes people feel comfortable. Often basking in the sun during winter not only promotes blood circulation, enhances metabolism and immune function, but also can prevent rickets in children and has special curative effects on osteoporosis in adults. The ultraviolet rays in the sunlight have strong sterilization capabilities; general bacteria and certain viruses will be killed after being exposed to the sun for half an hour or a few hours. For example, it can kill pathogens of various respiratory tract infectious diseases, such as influenza virus, measles virus, Neisseria meningitidis, etc. Basking in the sun can delay aging and maintain health, and what plays a role here is vitamin D. Studies show that in winter health care, those with higher levels of vitamin D in their bodies are about 5 years younger on average than those with lower levels of vitamin D. About 90% of the vitamin D required by the human body needs to be obtained through exposure to the sun.
