Ultraviolet radiation in sunlight and artificial lighting systems: Are they alike?

Abstract

Nowadays, we are urged to avoid the sun to avoid the UVR (ultraviolet radiation) especially since the data indicate that the growing cases of melanoma and cataracts occur due to it. So, we stay out of the sun. Moreover, artificial light has UVR and, even though the amount of UVR under artificial light is much less than under sunlight, the truth is that the time that we spend indoor, with the lights on, is way too much. The light has a great impact on our visual and non-visual requests. These facts are responsible for many of our health complaints. Still, what are the differences between the natural UVR (sunlight) and the artificial UVR (artificial light)? The objective of this paper is, through literature review, examine the way we balance our needs and how we can promote our health and wellbeing.
