5. Dim your gadgets’ brightness YOU'LL GET MORE SLEEP
According to the National Sleep Foundation’s 2013 International Bedroom Poll, almost three-quarters of people watch TV or use electronics in the hour right before bed. And why is that not a great idea? A 2012 study from the Lighting Research Center at Rensselaer Polytechnic Institute showed that light from backlit screens can reducethe production ofthe sleep chemical melatonin by 22%. If you’re drawn to the screen like a moth to a MacBook, dial down your display’s brightness to drift off easier.
