Is it possible that we've been wrong about sunscreen all along?

The Shady Link Between Sunscreen and Your Health
The benefits reaped from sun exposure might outweigh the skin cancer risks, or at the very least, most people probably skew too far towards hiding from the sun, when a bit more balance would likely provide the best of both worlds. While skin cancer is serious, it isn’t very prevalent when compared to numerous other (potentially deadly) ailments that exposure to the sun has been shown to remedy. Vitamin D appears to be more of a marker of good health rather than a deficiency that can be made up through supplementation.

How did we get it so wrong? How could people with low vitamin D levels clearly suffer higher rates of so many diseases and yet not be helped by supplementation?

As it turns out, a rogue band of researchers has had an explanation all along. And if they’re right, it means that once again we have been epically misled.

These rebels argue that what made the people with high vitamin D levels so healthy was not the vitamin itself. That was just a marker. Their vitamin D levels were high because they were getting plenty of exposure to the thing that was really responsible for their good health—that big orange ball shining down from above.

One of the leaders of this rebellion is a mild-mannered dermatologist at the University of Edinburgh named Richard Weller. For years, Weller swallowed the party line about the destructive nature of the sun’s rays. “I’m not by nature a rebel,” he insisted when I called him up this fall. “I was always the good boy that toed the line at school. This pathway is one which came from following the data rather than a desire to overturn apple carts.”

Weller’s doubts began around 2010, when he was researching nitric oxide, a molecule produced in the body that dilates blood vessels and lowers blood pressure. He discovered a previously unknown biological pathway by which the skin uses sunlight to make nitric oxide.

Is Sunscreen the New Margarine?
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.”
