According to a recent study, gamers who play for more than seven hours a week sleep less than casual or non-gamers. The study claims to have linked a direct correlation between the number of hours played and sleepiness. During the 2009 SLEEP event, it was shown that avid gamers snooze less throughout the week and have higher rates of sleepiness.
As a whole, hardcore gamers were observed to exhibit poorer sleep habits than light gamers. On average, participants who reported that gaming interfered with their sleep slept for 1.6 hours less than other gamers. Even further, those who claimed to be addicted to gaming averaged one hour less sleep on weekdays.
While the statistics showed that admittedly addicted gamers scored higher on the Epworth Sleepiness Scale, only about one third of them recognized sleep interference. Personally, I can attest that when Im hooked on a game, I often exchange hours in dreamland for those in a digital reality.
