A new Norwegian study of over 45,000 studies has found that every additional hour of screen time is tied to a 63 percent increase in the chances of battling insomnia, as well as 24 minutes less sleep.

The Norwegian Institute of Public Health's Dr. Gunnhild Johnsen Hjetland said: "We found no significant differences between social media and other screen activities, suggesting that screen use itself is the key factor in sleep disruption."

The researches noted that while a correlation has been found between the two, they have not confirmed that screen use necessarily causes lower sleep quality.

Dr. Hjetland added: "This study cannot determine causality — for example, whether screen use causes insomnia or if students with insomnia use screens more."

For the 2022 study, which has now been published in a Frontiers journal - participants were quizzed on their digital media habits before bed, including browsing the web, gaming, social media and watching TV or films.

Of those who said they use screens in bed before they go to sleep, 69 percent use social media and other screen-based activities.

Those taking part in the study were also asked how often a week they engage with digital media before bed, and for how long, as well as how often they experienced issues with their sleep.
