Total sleep deprivation decreases flow experience and mood status

BACKGROUND: The purpose of this study was to examine the effect of sleep deprivation on flow experience. METHODS: Sixteen healthy male volunteers of mean age 21.4±1.59 (21-24) years participated in two experimental conditions, ie, sleep-deprivation and normal sleep. In the sleep-deprived condition, participants stayed awake at home for 36 hours (from 8 am until 10 pm the next day) beginning on the day prior to an experimental day. In both conditions, participants carried out a simple reaction time (psychomotor vigilance) task and responded to a questionnaire measuring flow experience and mood status. RESULTS: Flow experience was reduced after one night of total sleep deprivation. Sleep loss also decreased positive mood, increased negative mood, and decreased psychomotor performance. CONCLUSION: Sleep deprivation has a strong impact on mental and behavioral states associated with the maintenance of flow, namely subjective well-being.
