The literature widely acknowledges the deleterious effects of UV radiation on skin health, via production of oxidative free radicals. Consequently, there have been numerous studies on the potential dermatological/anti-carcinogenic benefits of anti-oxidants, such as vitamins C and E, melatonin, green tea, zinc, and selenium. There is, however, a limited amount of literature on the quantity of UV exposure in high-risk settings, such as extreme altitude and equatorial zones. Currently, there is no literature on UV exposure on Mount Everest. Additionally, the efficacy of antioxidants (topical or systemic) has not yet been established in this environment.
