“Nonsmokers who avoided sun exposure had a life expectancy similar to smokers in the highest sun exposure group, indicating that avoidance of sun exposure is a risk factor for death of a similar magnitude as smoking,” according to a 2016 study from Sweden.
“Compared to the highest sun exposure group, life expectancy of avoiders of sun exposure was reduced by 0.6–2.1 years,” the paper notes.
Life expectancy reduced in 50-60 yr old nonsmoking sun avoiders by 0.6 to 1.3 years
“Life expectancy was reduced in nonsmokers of approximately 50 and 60 years of age who avoided sun exposure by 0.6 and 1.3 years, respectively, compared to those with the highest sun exposure during the 20-year follow-up.”
Life expectancy reduced in 50-60 yr old smoking sun avoiders by 1.1 to 2.1 years
“The same comparison amongst smokers demonstrated a shorter life expectancy of 1.1 and 2.1 years, respectively.
Avoiding sun exposure is a risk factor for reduced life expectancy of similar magnitude as smoking
“It can also be seen from the graphs that nonsmokers who avoided sun exposure had a similar life expectancy compared to smokers with the highest sun exposure.”
“Thus, avoidance of sun exposure seems to be a risk factor of magnitude similar to smoking in terms of life expectancy.”
The study recruited 29,518 Swedish women in 1990 to 1992 and followed them for 20 years as part of the Melanoma in Southern Sweden (MISS) cohort.
