Is August 2nd to August 12 cloudy, sunny or rainy?

Pay attention to sun protection on sunny days.

In fact, the essence of sun protection is to prevent ultraviolet rays. Therefore, the methods that can isolate the harm of ultraviolet rays to the body are all effective sun protection methods.

Ultraviolet rays that cause skin damage can be divided into two categories:

One is called long-wave ultraviolet (UVA), which is characterized by strong penetrating power. Even in rainy days, it can penetrate the epidermis and reach the superficial dermis, causing various photosensitive diseases. One is called short-wave ultraviolet (UVB), which is not so penetrating, but it is the chief culprit of sunburn.

Therefore, effective sun protection is actually the weather regardless of season, as long as you go out during the day: between 10 and 14 every day, ultraviolet rays are the strongest. When you are outdoors at this time, you must have the most serious ultraviolet poisoning. UVA can penetrate the clouds and reach the ground in rainy days, so don't think that without the sun in the sky, there will be no ultraviolet rays.
