Exposing our skin to the sun can be good for our health
To many people the idea of naturism is unthinkable, but naturists claim that exposing our bodies to sunshine and fresh air has many health benefits. You can read more about it by clicking the link below. What are you waiting for... get naked....lol http://www.msn.co.uk/health/naturism/
The only benefits I can think of are, your body produced vitamin D, you get an even all over tan and it is a great way of socializing.
A word of Caution. Over exposure can damage your skin, leading to cancer, so cover up when the sun is too strong. Too much sun can also make your skin age quicker.
