Can’t sleep? Stop looking at your phone or tablet in bed, says study

Blame America’s sleep deprivation on glowing screens.


Do you check your e-mail before going to bed—or even just watch a little TV to unwind in the hour before hitting the hay?

Those habits might be keeping you awake, according to a study by the National Sleep Foundation (NSF).

The NSF says the glowing screens on the TV, computer, cell phone, or tablet are affecting your sleep. The Washington, D.C.-based organization said:

“Unfortunately, cell phones and computers, which make our lives more productive and enjoyable, may be abused to the point that they contribute to getting less sleep at night leaving millions of Americans functioning poorly the next day.”

Here’s the deal: Exposure to artificial light before bed can increase alertness and suppress the release of the sleep-promoting hormone melatonin, the NSF said.

The study found that 95 percent of people questioned said they use an electronic device in the hour before bed, and roughly two-thirds said they don’t get enough sleep during the week.
