A ‘sleep debt’ is widely reported among adolescents. Addressing this is of societal importance given that sleep deprivation has been linked to a range of cognitive and affective disturbances. Initial evidence suggests that modest gains in total sleep time over a week or less can improve attention and mood in adolescents; however, extant studies have methodological caveats and findings have been inconsistent. The present proof-of-concept study tests a protocol for extending sleep duration in teens. We also explored whether this has benefits for daytime sleepiness, mood, attention and word learning. Thirty-nine 13-15-year-olds who were sleeping less than the recommended 9 hours per night completed one week of baseline sleep monitoring before being randomly allocated to a control (business as usual) group or a four-night sleep extension group where individuals’ bedtimes were gradually brought forward. The extension protocol successfully increased total sleep time by ~50 minutes on average but did not alter sleep efficiency or time spent in different sleep stages. Decreases in subjective sleepiness were associated with increases in sleep duration. There were no observed benefits for mood or cognitive abilities. These data suggest that adolescent sleep can be modified over a short time span, and call for further research into how to optimize sleep to bolster cognitive and affective performance in adolescence. |
