Scientists from the University of Pennsylvania (USA) found out that watching TV at night increases the likelihood of insomnia. Their study aimed at examining the effects of TV-watching on the process of falling asleep and sleep in general.

The experiment involved over 21 thousand volunteers. They discovered that falling asleep while watching TV disturbs sleep cycle for a long time and increases chances of insomnia. The scientists recommend turning off TV at least half an hour before falling asleep.
