Generally, you don't want to wear sunscreen on cloudy days. Is the ultraviolet ray weaker on cloudy days than on sunny days?

Ultraviolet rays on cloudy days cannot be ignored.

I don't think I was ignored by Bian Xiao. I can't see the sun. The sun is very strong. As we all know, there are many forces that affect it, such as the weakness of ultraviolet rays every day, because ultraviolet rays are affected by the height of the sun. In addition, the latitude of our latitude is also related to the weakness of ultraviolet rays. Most of us know that the ultraviolet rate is also related to this season. For cloudy days, ultraviolet rays also exist, and their power cannot be underestimated. The ultraviolet rays in front of the border hills in Bian Xiao are negligible, and there are no sun protection measures, which is very good. Now that I think about it, it's just to realize my desire.

The ultraviolet rays behind the white clouds are unimaginable.

For cloudy and sunny days, cloudy weather is king. On a clear day, when clouds cover half the sky or even the whole day, the ultraviolet intensity on the surface may be higher than when there are no clouds. According to research, it is as high as 25%, exceeding the ultraviolet index 15. At noon, when the weather is hottest, the ultraviolet index is only 8? 9. So, when we naively parted the clouds, I didn't. I know that I am ultraviolet rays that pass through beautiful black clouds.

No matter what season or weather, please do your job and go out. For Miss Amy, you must remember sunscreen and sunscreen cosmetics. For fairies who like Su Yan, they can wear hats, sunglasses and masks on cloudy days or in low-heat weather. Masks can also protect against the sun.

No sun protection in summer, be careful! Ultraviolet rays are really terrible!

1 can cause skin aging and skin cancer.

Many experts show that incorrect ultraviolet radiation can lead to skin aging, wrinkles, and even skin cancer and lupus erythematosus. UVB can not only cause skin tanning, but also directly reach the dermis of the skin, destroy collagen and elastic fibers, and produce light seals that can be superimposed and accumulated. The lasting effects are sunburn and skin aging. 50% to 70% of skin cancers are caused by excessive ultraviolet radiation, including skin malignant melanoma, skin squamous cell carcinoma and skin alkaline carcinoma.

2. Ultraviolet is the first enemy of freckles.

Many freckles are caused by heredity and cannot be cured. Ultraviolet light is the main reason why many people have more freckles and darker colors in summer. In winter, the number decreases and the color becomes lighter. Freckle-removing friends should not take photosensitive drugs, such as granular protein and methoxy, eat less photosensitive foods, such as celery and coriander, and eat more fruits and vegetables rich in vitamins. Wearing a hat and sunglasses in summer is also suitable for sun protection.
