Tanning is the human body’s natural and intended response to ultraviolet light exposure. Throughout human evolution a tan has served as the body’s natural acquired protection against sunburn and overexposure. Today we know that a suntan achieved in a non-burning fashion, combined with proper use of sunscreen outdoors when sunburn is a possibility, is the best way to maximize the potential benefits of regular sun exposure while minimizing the risks that are associated with overexposure.
