How to bask in the sun to be healthy?

In fact, there are two periods of the day that are most suitable for sunbathing. One is between 6: 00 am and 10. At this time, infrared rays prevail and ultraviolet rays are low, which can make people feel warm and soft and promote blood circulation. The other is at 4-5 pm, when the alpha beam of ultraviolet rays prevails, which can promote the absorption of calcium and phosphorus in the intestine and generate vitamin D, which is beneficial to strengthening physical fitness and promoting the normal calcification of bones. As far as the sun exposure time is concerned, 10-20 minutes is generally enough. A quarter of an hour in the morning, a quarter of an hour in the afternoon, half an hour a day, the solar energy in the body is enough.

Of course, sunbathing also has some taboos. For example, no matter what season or place, it is not suitable for sunbathing for a long time, from 10 in the morning to 4 pm. If you have to run in the sun for some reason, you'd better take sun protection measures, such as wearing sunscreen and wearing a hat to weigh an umbrella, because the energy in the sun is the strongest at this time, which is easy to damage the skin and most likely lead to high incidence of skin cancer. In addition, sunbathing is not for the villagers to hide, because the sun has to be in close contact with the skin to produce vitamin D, so when sunbathing, try to expose the skin. If you are sunbathing in winter, don't go indoors to sunbathe through the huge French window, because it is too cold. The energy of sunlight passing through the glass is almost exhausted, and it makes no difference whether it is basked or not.
