The concern with the Sun is that UV rays are damaging the elastin and collagen proteins in our skin - so the real goal is to avoid the direct UV radiation as much as realistically possible, not to never see the sunlight. :) In fact, sunlight exposure is very important for other crucial mechanisms in our body like melatonin regulation and D vitamin production. You still can have all the benefits and fun by simply being more active in morning and sunset, avoiding midday exposure (which is already part of the culture in many sunny regions), and wearing the sunscreen and proper clothing to protect your skin. Of course, how much UV exposure do you need for you body to function normally and not let sun ruin your skin depends primarily on where you live, is it summer or winter, etc. It all comes down to limiting how much UV radiation you'll get. If you're dark skinned it also helps - the melanin in your skin acts as an additional layer of protection against UV rays.
