Non-smokers who avoid sun exposure are at the same risk of cancer and heart disease when compared with smokers.

‘Women with active sun exposure habits have a longer life expectancy as there is a reduced risk of heart disease.’

Whether the positive effect of sun exposure demonstrated in this observational study is mediated by vitamin D, another mechanism related to UV radiation, or by unmeasured bias cannot be determined. Therefore, additional research is warranted. 




"We found smokers in the highest sun exposure group were at a similar risk as non-smokers avoiding sun exposure, indicating avoidance of sun exposure to be a risk factor of the same magnitude as smoking," said Dr. Pelle Lindqvist, lead author of the Journal of Internal Medicine study.
