Many individuals experience insufficient sleep and psychosocial stress, frequently accompanied by adverse effects on health, well-being and cognitive performance. Although sleep loss and social stress often co-occur in today's society, there is up to date a lack of knowledge on the effect of acute social stress in sleep-deprived individuals. Consequently, the main aim is to use a systematic experimental approach to study how acute social stress affects sleep-deprived individuals compared with well-rested individuals. Subjective and physiological measures as well as cognitive performance will be studied. A second aim is to determine if older individuals (55- 70yrs), who may be less affected by both sleep loss and stress, react differently than young adults (20-30yrs). This research fills a gap in an internationally acknowledged research area, and is important from a health and safety perspective. Individuals that face social stress under conditions of sleep loss (e.g. medical doctors or police officers during night shifts) may both have an altered, dysfunctional physiological stress response and display cognitive performance impairments that result in errors in their work tasks. The proposed research will provide novel insights on interactions between sleep loss and stress. These results may also be used to develop prevention strategies in the future.
