Go dark. It’s known that the light from a smartphone interferes with sleep. But what about your bathroom light? If you have the urge to go at night, don’t flick on the lights. “The latest recommendation is to use a flashlight if you need to get up at night,” Gamaldo says, because it offers less visual disruption.

Happily, there are easy, natural fixes that can improve your sleep, says Charlene Gamaldo, M.D .
