About this listen
This research article from Sleep Medicine Reviews proposes an updated bidirectional model for understanding the complex relationship between technology use and sleep. The authors, Bauducco et al., challenge previous unidirectional theories by asserting that sleep problems can also influence technology use, not just the other way around. The article thoroughly examines established mechanisms like bright light and arousal hypotheses, finding their impact on sleep less significant than often assumed. It also introduces and supports "sleep displacement" and "nighttime sleep disruption" as key mechanisms where technology significantly impacts sleep, along with new mechanisms where technology acts as a "time filler" or "emotion regulation tool" when sleep is difficult. Finally, the authors explore individual risk and protective factors like self-control and parental rules, offering implications for future research and public health messaging to promote healthier technology habits for sleep.
