New study shows that cell phones, computers disrupt sleep

If you’re counting sheep instead of catching Zs every night, your cell phone and computer may be to blame, according to a new survey released Monday.

Ninety-five percent of those polled by the National Sleep Foundation said they use light-emitting technology in the hour before bed, with 60 percent of them reporting they have a sleep-related problem every night, such as snoring, waking up too early or still feeling tired in the morning.

Dr. Charles Czeisler, a member of the foundation’s Sleep Task Force in charge of the poll, said exposure to light from electronic devices interferes with the body’s sleep-promoting hormone melatonin and disrupts internal clocks that control when you fall asleep and wake up.

The study found that age groups varied in the kinds of technology they use before bed. Sixty-seven percent of 46 to 64-year-olds said they watched TV before snoozing, while about half of 13-to-29 olds reported flicking on the tube.

That group said they usually text or play video games, with more than 50 percent of 13 to 18-year-olds reporting that they text before bed.

Researchers found that even after people hit the hay, late-night text messages or cell phone alerts can jolt them awake.

Jose Martinez, 23, of Washington Heights said texting and surfing Facebook frequently keeps him up late and texts often wake him up in the middle of the night.

“For a week I tried to turn off my cell and stayed away from my computer before bed, and it worked,” at getting him to sleep, “but then I felt like I was missing something,” he said.

Juliana Caputo, 20, of Midtown, said she gets “really agitated” when friends text her after a night of drinking.

But sometimes just knowing her cell phone is on is enough to interrupt her dreaming, she said.

“If you go to sleep knowing to expect a phone call, you wake up during the night to check if they called,” she said.
