Using smartphones, tablets, or laptops for just one hour before bedtime can considerably disrupt sleep patterns, increasing the risk of insomnia by 59% and reducing average sleep duration by 24 minutes, according to a recent study.
Sleep disorders are known to negatively impact overall quality of life and are often associated with mental health issues. Research indicates that individuals struggling with sleep are more susceptible to anxiety and depression. Optimal brain function relies on 7 to 9 hours of sleep per night, which is crucial for learning and cognitive processes.
Study Details
The study, involving over 45,000 Norwegian young adults aged 18-28, examined the correlation between smart device usage and sleep quality. Participants completed questionnaires detailing their pre-sleep habits,including the type and duration of smart device use. Researchers also collected data on sleep onset time, sleep duration, sleep latency, sleep disturbance frequency, and daytime sleepiness.
Insomnia was defined as experiencing difficulty falling asleep or maintaining sleep at least three times per week for a minimum of three months.
Key Findings
The analysis revealed a clear link between smart device use and disrupted sleep patterns. Interestingly, the specific type of content consumed on these devices did not appear to significantly alter the impact. Researchers initially hypothesized that social media use might have a more detrimental effect, but the study found no substantial difference compared to activities like watching movies, playing games, browsing the internet, or listening to audio.
“The content type is not as important as the total time using smart devices in bed,”
Gunnhild Johnsen Hjetland, NIPH researcher, Frontiers in Psychiatry
According to the frontiers in Psychiatry journal, Norwegian researchers suggest that reducing pre-bedtime screen time can effectively improve sleep quality.
Recommendations for Better Sleep
Dr. Hetleland recommends ceasing smart device use at least 30 to 60 minutes before going to sleep. Additionally, silencing notifications and disabling vibrations can prevent disruptions once drowsiness sets in.
Contrary to popular belief, the study suggests that blue light emitted from screens may not be the primary culprit. Lowering screen brightness is considered more effective than relying on blue light blocking glasses or apps.
The type of content consumed also plays a role. Studies indicate that watching scary movies or engaging with stressful social media content can elevate stress hormones, reducing the amount of deep sleep (essential for physical restoration) and REM sleep (crucial for mental recovery).
To promote relaxation before sleep, consider reading a physical book or e-book. Research suggests that reading before bedtime can enhance sleep quality.
