Screen Time, Sedentary Behaviour, Sleep Duration, and Physical Activity

Screen behaviours are highly prevalent in adolescents. Understanding how screen behaviours inter-relate with physical activity and sleep may help to clarify pathways through which they impact health and potential routes to behaviour change. A recent cross-sectional study examined the association of contemporary screen behaviours with physical activity, sedentary behaviour, and sleep in adolescents.[1] Screen time was found to be associated with less time in moderate-to-vigorous physical activity and sedentary behaviours. All screen behaviours were associated with shorter sleep duration. Gender difference was absent. In conclusion, the authors suggested that intervention strategies to enhance moderate-to-vigorous physical activity and sleep duration by limiting screen-based activities may be warranted.[1]

From my personal experience, screen activities, be it work or leisure, do distract me from planned physical activities. Blaming on the screen device is no more than blaming any form of distraction, I just have to manage my discipline!
