Now that the days are getting warmer, and we’re spending more time outdoors, keep this in mind: Be careful using your tablet computer or even your giant smartphone in the sun. You know how people in the 1950s and 60s would hold those silver tanning reflectors under their faces? Well the shiny surface of an iPad works the same way. It can increase your UV ray exposure by 85%… And a smartphone increases it by 36%. That’s according to the American Academy of Dermatology. So wear sunscreen every day on your face and neck – and be cautious about using your iPad outside on a sunny day.
