Leaving your phone in another room when you turn the lights out helps you avoid the temptation to check—and you avoid the risk of a stray beep or buzz waking you at all hours, Greenfield says. Do invest in an alarm clock that’s not connected to your phone. Ten dollars is a small price for better sleep.
Also aim to limit digital time before you call it a night. The National Sleep Foundation recommends turning off electronics at least an hour before bedtime—especially avoiding anything interactive, including video games, surfing the web, and texting—for better quality sleep.
