Does sunbathing work in winter in the north?

We all know that the winter in the north is colder, because according to geographical knowledge, the winter in the north is located in the tropic of cancer and belongs to the temperate continental climate, so the winter in the north is several times colder than that in the south. Therefore, the winter in the north must rely on heating and sunbathing to solve the heating problem. If the heating is not good, it is easy to catch a cold because of being in a cold environment for a long time.

? Therefore, in winter, besides heating, there is also a good thing, that is, the sun, because the heating will definitely not burn for you all the time, so sunbathing has become a good thing. Natural heating tools, like me, are people who are particularly afraid of cold. In winter, they must be people who wear thick clothes. So, I was used to sitting in a classroom with heating. However, a person will definitely not sit in a heated position all the time, so if he can't sit in a heated position, he can only sit in the sun. Because it is cold in winter, that is, it is cold in the morning and warm in the afternoon, so sitting in the sun in the morning is very happy.

? Teenagers, for example, are in the developmental stage, and the sunshine is rich in nutrition. More sunshine can promote the development of skeletal muscle, which is good for the health of teenagers. The sun in summer is toxic and the ultraviolet rays are strong, which may make them get photosensitive dermatitis. Therefore, there is still less sunshine in summer, but more sunshine in winter can not only keep their bodies in a warm stage, but also promote their development and qi and blood. How nice it is to have the best of both worlds.
