The study's findings suggest that late-night screen time may not be as detrimental to sleep as previously thought, with the real concern lying in screen use once in bed.
Interestingly, while screen time before bed correlated with later sleeping, it balanced out with later wake times, indicating no overall sleep duration loss.
The research showed that usage of screens post-bedtime was much more damaging, indicating a significant drop in total sleep time correlating to the amount of time spent on devices.
Researchers emphasized that the method of using wearable cameras allowed for a more accurate depiction of screen usage patterns, overcoming limitations of self-reported data.
