Flip through a photo album before bed! British researchers found people who looked at happy photos of loved ones before bed saw a huge drop in levels of stress hormones. And they were able to drift off faster, and sleep longer, than when they didn’t look at pictures. It reminds us of happy times and the people who love and support us. But know this: They have to be printed pictures, not smartphone snapshots. Because staring at lighted electronic screens within an hour of bed has been shown to make it harder to get to sleep.
