Despite persistant warnings about the dangers of excessive exposure of the skin to the harmful rays of the sun, people still seem to be obsessed with getting the perfect tan. Whether it's at the beach, in the backyard, or poolside at some resort, many people devote great amounts of time to sun worship in the form of lying prostrate, and at least partially naked, under the great solar deity in the sky, hoping to change the color of their skin in the process. Although a tan might look healthy, the truth is that too much exposure to the sun's rays increases the likelihood that skin cancer will develop later on in life. The use of sunscreen can provide some protection against harmful ultraviolet rays and so it's definitely a good idea to slather on plenty of the sun-blocking lotion and to make sure that it has a high SPF (Sun Protection Factor) rating. So, remember to practice moderation and be careful not be become overdone by the sun!
