Abstract

Public health messages clearly state the risks of solar radiation and how the risk can be mitigated. This is supported by the availability of creams that effectively block out the ultraviolet component of solar radiation. Why then does the incidence of skin cancer and particularly melanoma remain so disturbingly high in Caucasian populations?


Almost all organisms on the planet have had to adapt to the presence of solar radiation since the beginning of evolutionary time. There are beneficial effects as well as risks in exposure, not the least of which is that it is the ultimate energy source for living species.


We need to re-examine attitudes and exposure patterns with an appreciation that some exposure is essential for good health. A balance needs to be found between benefits and risks. This can only be done by understanding that there are a range of wavelengths of light with different effects rather than a focus solely on the adverse effects of the ultraviolet component.

Keywords: visible light, influence of visible light, influence of visible light within the solar spectrum, human skin, sun protection, sun protection measures
