There’s a fine line here. Sun exposure provides the body with vitamin D which is helpful in preventing cancer. But overexposure can result in skin cancer. You have to be cautious.
Fair skin people “like me” have to be careful and use common sense. My wife and I live in a rainforest and are naked a lot. We call sun burns here the “9 degrees” burn. We are 9 degrees from the equator, hence the name. You are burn extremely fast. It is very common to keep a vented long sleeve shirt with you at all times. We never go on the water without sun screen protection on our face.
Absolutely. Especially in fair-skinned Anglo-Saxon people, and especially again those with many moles or freckles. It is repeated exposure to intense sun on parts of the body that are not normally exposed that are highly vulnerable to skin cancer. I've had a few basal cell carcinomas removed, but also quite a few more squamous cell carcinomas -- the "poor cousin" of the lethal melanoma (I had three removed 11 years ago with no sequalae). Vitamin D does not prevent skin cancer. Vitamin D is obtained normally through everyday exposure to the sun. In nordic/arctic countries, people have Vit. D supplements because of the very short daylight hours. Such supplements are not needed in healthy people, but it is often given to older, less active people as a complement to managing things like osteoporosis.
As I said, there’s a fine line here. Vitamin D isn’t a cure all but it plays a part in fighting cancer cells. My wife had breast cancer and was told to increase her vitamin D with supplements by her oncologist. I’ve also read articles where many doctors are proponents of it to combat cancer.
