Sleep Debt in Student Life: Online Attention Focus, Facebook, and Mood
summary
Seventy-six college students are monitored for seven days using logged computer and phone use plus sleep diaries and daily surveys; analysis uses linear mixed models controlling for age, gender, workload and deadlines. Median sleep is eight hours, average computer focus is just over one minute and Facebook use averages about 28 minutes per day. Less sleep predicts shorter focus and higher perceived work pressure; greater sleep debt predicts more Facebook use and worse affect, while longer sleep oddly correlates with lower self-rated productivity.
