You read on your iPad outside
University of New Mexico researchers published the results of an interesting experiment last year: They set up a mannequin head (wearing a UV light meter to detect sun exposure) and faced it toward a music stand, then placed various types of mobile devices on the stand to see how they’d impact the amount of UV light the mannequin would receive. They found that the glare reflected by an iPad could increase UV exposure by 85 percent; an iPhone can increase exposure by 36 percent. Unless devices are designed to be less reflective, or to have built-in UV sensors so people could track their exposure, the safest solution for beach or poolside readers is to slather on the sunscreen, wear a hat and sunglasses, and sit under a tree or umbrella.
You enjoy alcoholic beverages
When Harvard Medical School researchers analyzed data from 300,000 people in 2006, they made two findings. The first was that sunburn is common—34 percent of respondents said their skin had been scorched within the past year. (These home remedies can help treat sunburn). The second was that sunburn is more likely in those who consume alcohol. Heavy drinkers, those who had five or more alcoholic beverages on one occasion, had a 22 percent greater risk than teetotalers. But even those who only had one drink reported more burning. The toll from imbibing is substantial, concluded lead researcher Kenneth J. Mukamal, MD, who estimated that 18 percent of all the sunburns were attributable to alcohol use.
