Study: TV, cell phones interfere w/ sleep habits

March 7, 2011 12:00:00 AM PST
A new study shows televisions, cell phones and laptops are interfering with people's sleep habits.

Nearly 95 percent of the people who took part in the study said they used some type of electronics an hour before going to bed. Of those, two-thirds admitted to not getting enough sleep.

Researchers say the reason may be that exposure to artificial light from electronics can increase alertness and suppress the release of melatonin, a sleep promoting hormone.

The most sleep deprived in the study was the 13 to18 age group. Twenty-two percent described themselves as sleepy, compared to just nine percent of baby boomers.
