So Lindqvist decided to look at overall mortality rates, and the results were shocking. Over the 20 years of the study, sun avoiders were twice as likely to die as sun worshippers.
There are not many daily lifestyle choices that double your risk of dying. In a 2016 study published in the Journal of Internal Medicine, Lindqvist’s team put it in perspective: “Avoidance of sun exposure is a risk factor of a similar magnitude as smoking, in terms of life expectancy.”
I remember as a kid playing outside constantly in the sun, without a drop of sunscreen on. I always had a tan of some sort, my parents too. Seems like that's how things are supposed to be. Spending all your time indoors means that when you do see the sun, you're more likely to get burned, necessitating the sunscreen.
