I had done a small bit of research online some time back to know what was best for sun exposure and vitamin D. And had concluded that sunscreen on your face, ear and neck which are more likely to burn and also cause wrinkles, with about 20 to 30 minute of direct sunlight exposure on your body per day was the current recommendation. I think one issue is it's not very socially accepted for me to take a walk shirtless in the middle of the day. So I had found it quite hard to take in the sun. The other thing I had read was that clothes accentuate skin cancer, because it means that we expose the same parts over and over to sun, yet we get way less amount of vitamin D and other benefits for the amount of time we are out. Like 5 minutes out in the sun naked, you get a lot of surface sun, but no part of the skin is exposed for too long. While if you go out for 1 hour in the sun with clothes, you might have sunburn in the exposed areas yet didn't even get as much vitamin D from it.
