Summer's already here unofficially in North America. Time for us all to hit the beach remember to wear sunblock, a hat, and sunglasses.

Sunlight helps us maintain sufficient vitamin D in our systems, historically warding off tuberculosis and ricketts and possibly lowering the risk of some cancers (lung, colon, and breast cancers).

However, exposing our skin to too much ultraviolet (UV) light contributes to a host of health problems, sunburn being just the most immediate and obvious.
