Ultraviolet (UV) radiation is a ubiquitous component of the environment that has important effects on a wide range of cell functions. Short-wavelength UVB radiation induces sunburn and is a potent immunomodulator, yet longer-wavelength, lower-energy UVA radiation also has effects on mammalian immunity...
UVB causes sunburn, and is linked to particular types of skin cancer — basal cell carcinoma (the most common type) and malignant melanoma. 中波紫外线UVB会导致晒伤,并与特定类型的皮肤癌——基底细胞癌(最常见的皮肤癌)和恶性黑色素瘤有关。 Sunscreen doesn't stop all types of skin damage so for...
The Measurement Of Ultraviolet RadiationAnd Sunburn Time Over Southern OntarioAnd Mexico CityW.F.J. EvansR. Acosta
The only recognised beneficial effect is that of endogenous photosynthesis of vitamin 0 from its precursors in the skin, the importance of which is greatly diminished by a well balanced diet. Acute excessive exposure to ultraviolet radiation (UVR) causes sunburn, whereas chronic overexposure is ...

Here is how sun damages our skin: study But even if you don't get a sunburn, ultraviolet radiation causes changes in skin DNA that can lead to cancer, Huang said. How to Protect Against Short- and Long-Term Sun Damage This type of melanoma occurs after exposure of the skin to too muc...
Dr Sharon Harvey, R&D program manager at Wine Australia, agrees. "We've noticed the effects of climate change in our sector for quite a while. We've seen more climate extremes, heat waves, sunburn, changes in our pests and disease regimes that effect the grapes." ...
Sunlight is one of the main harmful exogenous factors that induce the reactive oxygen species formation. The human skin is the first line of photoprotection against harmful exogenous factors, such as UV radiations. The topical application of sunscreens, containing UV-B filters, is widely used to ...
