The health benefits of sunlight may outweigh the risk of skin cancer

The way I see it: If you live where your ancestors lived for thousands of years and if you make sure your skin gets gradually attuned to the sun each year, you probably get more health benefits. But beware if you're of Northern European ancestry living in Southern USA or Australia or if you work an office job and only seek the summer sun with pale skin.

> make sure your skin gets gradually attuned

Is this a thing? Surely DNA damage from UV is dose-dependent, in which case any greater amount of UV results in a greater chance of skin cancer.

Is this a joke? Yes, it's called 'tanning'.

Having more melanin decreases the effective dose because any photon that melanin absorbs isn't going to be absorbed by your DNA.
