UV Exposure and Health
It has been widely shown that exposure to sun causes a variety of diseases including Melanoma. This includes recent work by Pearce, Barnett and Kingham (2005). What is less known are the positive benefits of exposure to sunlight through increases in levels of Vitamin D. Exposure to Vitamin D through sunlight is strongly linked to latitude. As a result of its geography, New Zealand is potentially a great place to study this. This study will assess the health impacts of exposure to sun in New Zealand .
