Our skin needs ultraviolet rays to make vitamin D; Wollard-Biddle says it's vital to our health. "Vitamin D is necessary for calcium absorption. If we don't have vitamin D our bones are not as strong as they should be," she says. Putting on sunscreen actually blocks against the production of vitamin D, that's why some scientists are now saying 15 minutes in the sun a few times a week without sunscreen is safe. They also say that time out in the sun is good for your health, possibly protecting us against prostate, lung, colon, and skin cancers. This doesn't mean though people should stay out in the sun all day long; remember moderation is key. "Fifteen minutes a few times a week is a good idea, but if you're going to stay out 30 minutes or an hour you need to wear sunscreen," Wollard-Biddle says.
Despite what studies find, Tyler Barnhart says he's not changing how he takes care of his four year old son Austin. "He's younger. His skin is more sensitive to sun and I make sure I protect him," Barnhart says.
