Since people don't know when is the best time to sunbathe, we often see some people sunbathing in the morning, some at noon, and some even in the afternoon. But when is the best time to sunbathe? I believe many people have doubts about this. Sunbathing is extremely helpful to the body, so when is the best time to sunbathe? We know that sunbathing has benefits such as promoting calcium absorption, but not many people can explain why. In fact, the most important factor affecting human calcium absorption is the metabolite of active vitamin D. Vitamin D is obtained mainly through two ways. One is from food, and the other is to synthesize vitamin D3 after the ultraviolet rays in sunlight irradiate the human skin. It can promote the absorption of calcium in the small intestine and even in the colon. If the human body lacks vitamin D, the calcium absorption rate is only 10%; if the body contains enough vitamin D, the calcium absorption rate will increase to 60%-75%. Vitamin D is also called the "sunshine vitamin". The vitamin D3 source contained in human skin is produced and converted into vitamin D by absorbing ultraviolet rays in the sun. It can help the human body take in and absorb calcium and phosphorus. A person who never sees sunlight will have a much higher incidence of osteoporosis than the normal population. A survey shows that 45% of office workers get less than half an hour of sun exposure every day, about 36% get half an hour to one hour, 19% get one to five hours, and no one gets more time in the sun. Sunbathing is the main way for the human body to produce vitamin D, because the ultraviolet rays in the sun promote the efficient synthesis of vitamin D. For people with no skin problems, sunbathing for about 30 minutes a day can synthesize about 20,000 international units of vitamin D needed by the body. In fact, nearly half of people spend less than half an hour in the sun. Moreover, nearly half of the people do not have enough exposure to the sun, mainly before 8 a.m. and after 6 p.m. During these two time periods, the ultraviolet rays in the sunlight are weaker, which is not conducive to the synthesis of sufficient vitamin D. When is the best time to sunbathe? The above content contains the answer to this question. If everyone knows when is the best time to sunbathe, you might as well try to sunbathe yourself during this time period. Every time you sunbathe, you must ensure that your body is normal. It should be divided into morning sunbathing and play sunbathing. It is easy to get heatstroke when sunbathing when the sun is strong, so everyone should make the right distinction. |
