Television Viewing, Internet Use, and Self-Reported Bedtime and Rise Time in Adults: Implications for Sleep Hygiene Recommendations From an Exploratory Cross-Sectional Study

This study examined whether the availability of the Internet and TV in the bedroom and overall Internet use and TV viewing were related to sleep variables in a sample of 711 residents of Flanders, Belgium. Although the relations were small, there was some evidence of time shifting: Internet access in the bedroom predicted later bedtime (beta = .12, p < .05) and later rise time (beta = .11, p < .05) on weekdays and later bedtime (beta = .10, p < .001) on weekends. Internet use volume predicted later bedtime (beta = .10, p < .001) and rise time (beta = .07, p < .05) on weekends, and TV viewing predicted later bedtime (beta = .10, p < .05) on weekends. However, neither the availability of the Internet or TV in the bedroom, nor the volume of Internet use or TV viewing, was a significant predictor of reduced sleep window or tiredness. Reducing media use might not be important for sleep hygiene advice to adults.
