Television viewing, internet use, and self-reported bedtime and rise time in adults: implications for sleep hygiene recommendations from an exploratory cross-sectional study

Behav Sleep Med. 2012;10(2):96-105. doi: 10.1080/15402002.2011.596599.


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 (β = .12, p < .05) and later rise time (β = .11, p < .05) on weekdays and later bedtime (β = .10, p < .001) on weekends. Internet use volume predicted later bedtime (β = .10, p < .001) and rise time (β = .07, p < .05) on weekends, and TV viewing predicted later bedtime (β = .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.
