A: cloudy, bask in truth to reside indoor and same sunscreen
Have experience of person all know: even if no sunshine, without any protective skin as can be basked in drifting also after red and black. Why should that be?
This is because, uv both contains ultraviolet (UVA) polynikis medium wave, and contains ultraviolet (UVB), both penetration and strength each have a difference. Sunny, high intensity of UVB rays, the damage is very big, and skin in YinYuTian and indoor, UVB cannot penetrate the clouds and glass, influence will greatly abate. But meanwhile, UVA but can penetrate thick clouds and most transparent glass, if not value bask in, tanned skin, the same, the specter of sunburn.

Although we all know all the year round to prevent bask in, but few people into one of the absolute, sunshine abate naturally off guard. Actually, this is key, ultraviolet ray is not hot! Get up, speaking, more climbing the mountain, even feel cold cool, but then ultraviolet but was unusually strong. So for every 1,000 meters up will help increase 10%, ultraviolet ray. Also like in the seaside in lower altitudes, but because the water when the reflection action, ultraviolet ray will soon reach strong degree. So don't because stay in a cool place no fever will ignore bask in, especially cloudy, ultraviolet ray of more than we can perceive much stronger.

From birth day, each person's skin will gain a pen "sunshine capital" -- skin natural sunscreen ability. So, I even tan, sunburn, we'll soon reply here. But the wealth is limited. Scientists did an extreme experiment, the average 50 hours would cause the sun, and the sunlight time skin refers not only to the summer sun insolates, including daily all sunshine and contact. The more deadly is, our skin memory system will record of skin damage every sunshine degree, and gradually accumulate.
As is exposed to sunlight time increases, the skin of the "sunshine capital" also gradually be consumption, eventually will be unable to protect the skin. Research further find that generally in by the age of 20, will consume 50% of the "sunshine capital". Because of the individual differences, everyone in the disappearance of sun capital skin speed each are not identical, but from our 20s skin on, basically start serious "sunshine capital" is only just more than 2,500 hours.
