In this study, 58 adults kept a diary, which they had to record information about time spent with the media, place of use, and multitasking before bed. Electroencephalography tests that detect the electrical activity of the brain using small metal disks attached to the scalp captured parameters such as bed time, total sleep time, and quality of sleep.
Using the media one hour before bed time is associated with earlier bedtime. If bed prepping does not involve multitasking and if conducted in bed, it is associated with a higher total sleep time. Prolonged use of media is directly influencing with post-sleep and shorter total sleep time. The quality of sleep was not affected by the use of media before bed.
“If you are going to use media, like watching TV or listening to music, before bed, keep it a short, focused session and you are unlikely to experience any negative outcomes in your sleep that night,” said lead author Morgan Ellithorpe, PhD, of the University of Delaware.
