TV Watching Before Bedtime: Leads to Sleepless Nights

June 8, 2009

(ChattahBox)— A new study suggests that turning on your TV before bedtime can cause you to stay up late and sleep less, resulting in chronic sleep deprivation, which is linked to serious health problems.

Researchers from the University of Pennsylvania School of Medicine, found that nearly 50 percent of the study participants watched TV before bedtime, which has the effect of replacing natural biological cues for sleep.

The researchers obtained their findings from analyzing the data from 21,475 people aged 15 or older who completed the American Time Use Survey between the years 2003 and 2006. The survey asked participants to list their activities two hours before and after bedtime, with the vast majority switching on the boob tube before bedtime.

The researchers believe that TV watching actually serves as a cue to stay awake with the sound of alarm clock alerting a person to awake.

Studies have shown that people who consistently sleep less that than 7-8 hours per day suffer from increased obesity, morbidity and mortality.

The researchers recommend that people give up TV watching at bedtime to promote a healthy sleep cycle and good health.

The research study is one of many sleep studies being presented at the 23rd Annual Meeting of the Associated Professional Sleep Societies.
