First of all, the ultraviolet rays contained in the sun have the function of sterilization and disinfection, and moderate acceptance makes the skin healthier. The sun in winter won't tan you easily. You can apply sunscreen when you go out to bask in the sun, which will also reduce the damage of ultraviolet rays. At the same time can make the skin healthier.
Therefore, solar energy can promote the absorption of calcium by human body, which is good for preventing osteoporosis and rickets. Our body needs calcium, and we can also absorb calcium nutrition in our daily diet, but getting more sunshine can help you absorb it better, because if you don't eat it, it means that the nutrition has been added to your body and needs to be absorbed.
Secondly, you should pay attention to some things when you are in the sun. A lot of ultraviolet rays will burn your skin and may even induce skin cancer. Too bright light can also hurt your eyes. ? It is recommended to bask in the sun at 8- 1 1 in the morning, and it should not exceed 1 hour at a time. Winter can be extended appropriately. Finally, the ultraviolet rays of the sun in winter are not as high as those in summer. More importantly, the temperature is not as high as that in summer, and the climate is not so hot. I am not afraid of tanning or heatstroke. If the sun comes out in winter, you might as well go around to bask in the sun, exercise and feel the warmth brought by the sun.
