People who spend more time looking at a screen in bed are more likely to report insomnia and sleep loss, a study has found. The research is based on a Norwegian survey of more than 45,000 students. It indicates that each additional hour of screen time was linked to a 63% increase in insomnia risk,

This finding comes from one of the largest studies conducted on screen use and sleep among university students, highlighting how our nightly digital habits may be robbing us of crucial rest.

A new Norwegian study finds that one hour of screen time at bedtime results in a 59% higher risk of insomnia and 24 fewer minutes of sleep. The findings indicate that social media use is no more disruptive to sleep than watching TV or movies or reading on a mobile device.
