Sun is a double-edged sword and a bit more complicated than sun good or sun bad. Too little sun is a problem. Sun exposure can lower all-cause mortality, but the risk of melanoma is not negligible. People get flus in northern climates partly due to lack of sun which weakens the immune system. Also depends on your diet. Better diet will protect you more from possible sun skin damage. Because sun has chemical reactions with the body. But the sunscreens also contain chemicals which react (negatively) with sun rays. I would avoid sunscreens, except very expensive ones with only natural ingredients and no chemicals or shady stuff you can't pronounce, but haven't tried them. Maybe best to avoid too much midday sun as UV rays may be too strong here in Thailand? I was going out midday unprotected a bit too much, I think, and taking a risk. Obviously, always avoid burns. And body adapts slowly to increasing levels of sun. Many people who get melanoma maybe it's because they come from a northern climate, avoid sun, and then go to a tropical beach vacation and get sunburned every day for 2 weeks. Body needs to acclimate slowly, which can be done if you are living in Thailand. But maybe only vampires should avoid the sun at all times. And maybe some folks on here are vampires. You never know who you're talking to on the internet.
