UV radiation from sun exposure is associated with an increased risk of skin cancer. But too little sun can result in severe vitamin D deficiency, a common condition that is also linked to cancer. Additionally, low vitamin D is associated with autoimmune disorders and several other diseases.
New research from Stanford University suggests that dermatologists must be aware that their recommendations to avoid sun exposure, particularly for patients at high risk of skin cancer, may be inadvertently creating other health problems.
The study was published in the October issue of the Archives of Dermatology and examined vitamin D levels in patients with a genetic pre-disposition to sun-related skin cancer called basal cell nevus syndrome (BCNS). Vitamin D levels of BCNS patients were significantly lower than control subjects matched for age, skin tone and geographic location.
