Smartphones before bed may increase risk of insomnia by 59% – study
Norwegian researchers found that regardless of whether you're scrolling through social media or reading a book on your smartphone, the negative impact on sleep will be the same.
Norwegian researchers found that regardless of whether you're scrolling through social media or reading a book on your smartphone, the negative impact on sleep will be the same.
A large-scale survey of 45,202 young people showed that just one hour of gadget use before bedtime increases the risk of insomnia by 59% and an average loss of 24 minutes of sleep per night, reports the Sci Tech Daily portal, citing a study published in the scientific journal Frontiers in Psychiatry.
According to Dr. Gunnhild Johnsen Hetland from the Norwegian Institute of Public Health, the main factor was not the type of activity, but the total time spent in front of screens in bed.
"We found no significant differences between social media and other screen activities, suggesting that screen use itself is a key factor in sleep disruption — likely due to a time shift where screen use delays sleep onset, taking away time that could be spent resting," Hetland said.
Study participants aged 18-28 reported difficulty sleeping and daytime sleepiness at least three times a week for three months of using smartphones before bed.
The author of the study recommends putting your phone away 30-60 minutes before bed and turning off notifications to avoid sleep disruption.
