Web, TV Cut Sleep Quality

Watching TV or surfing the web before bed can reduce the quality of sleep, a Japanese study has found. Reuters reports that people who unglue themselves from the screen before hitting the sheets reported less sleep, even though they sleep as much as the less addicted.

Fifty-four percent of those who spent more than 3 hours using the Internet or watching TV reported insufficient sleep, compared with 29% of those who were preoccupied for less than 1.5 hours. The study's lead researcher claims the disparity suggests TV and the web drains “sleep demand and sleep quality.” (More sleep stories.)
