DEPENDENCE on televisions, cell phones and laptops may be costing Americans dearly - in lack of sleep.
The penchant for watching television every evening before going to sleep, playing video games late into the night or checking e-mails and text messages before turning off the lights could be interfering with people's sleep habits.
"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," said Russell Rosenberg, the vice chairman of the Washington DC-based National Sleep Foundation.
Nearly 95 percent of people questioned in an NSF study said they used some type of electronics in the hour before going to bed, and about two-thirds of them admitted they do not get enough sleep during the week.
Charles Czeisler, of Harvard Medical School and Brigham and Women's Hospital in Boston, said exposure to artificial light before going to bed can increase alertness and suppress the release of melatonin, a sleep-promoting hormone. "Invasion of such alerting technologies into the bedroom may contribute to the high proportion of respondents who reported they routinely get less sleep than they need."
