During the cold winter months, many people may think that the sun is not strong and therefore does not need sun protection. However, in fact, winter sunlight still contains ultraviolet rays, and because the ozone layer in winter is thinner, ultraviolet rays are more likely to penetrate the surface. Therefore, sun protection in winter is also very important.
First of all, winter sunlight contains two types of ultraviolet light, UVA and UVB. UVA is a long-wave ultraviolet ray, which can penetrate glass and clouds, and is very harmful to **, and prolonged exposure to strong sunlight, especially direct summer sunlight, may cause **sunburn, sunburn, and accelerated aging**. UVB is short-wave ultraviolet light, although it will not penetrate glass and clouds, but its damage to ** can not be ignored.
Secondly, the ozone layer in winter is thinner, which makes it easier for UV rays to penetrate the surface. Therefore, in winter, even if the sun is not strong, we need to take sun protection measures to protect**.
In addition, the weather in winter is drier, and water is easily lost, which also increases sensitivity to ultraviolet rays. Therefore, in winter, we need to pay more attention to the best moisturizing and sun protection work.
In summary, sun protection in winter is also very important. We can protect by using sunscreen, hats, masks, etc. At the same time, it is also necessary to pay attention to maintaining the best moisturizing and healthy state. Only with all-round protection can we spend every season healthy and beautifully.
