However, the majority of previous research concerns young adults. Because susceptibility to sleep deprivation and emotion regulation change distinctively across adult age, we tested here the hypothesis that the effect of sleep deprivation on mood is stronger in young than in older adults. In an experimental design, young (18\u201330\u00a0years) and older adults (60\u201372\u00a0years) participated in either a sleep control (young, <jats:italic>n<\/jats:italic>\u00a0=\u00a063; older, <jats:italic>n<\/jats:italic>\u00a0=\u00a047) or a total sleep deprivation condition (young, <jats:italic>n<\/jats:italic>\u00a0=\u00a061; older, <jats:italic>n<\/jats:italic>\u00a0=\u00a047). Sleepiness, mood and common symptoms of sleep deprivation were measured using established questionnaires and ratings. Sleep\u2010deprived participants felt more sleepy, stressed and cold, and reported lower vigour and positive affect, regardless of age. All the other outcome measures (negative affect, depression, confusion, tension, anger, fatigue, total mood disturbance, hunger, cognitive attenuation, irritability) showed a weaker response to sleep deprivation in the older group, as indicated by age*sleep deprivation interactions (<jats:italic>p<\/jats:italic>s\u00a0&lt;\u00a00.05). The results show that older adults are emotionally less affected by sleep deprivation than young adults. This tolerance was mainly related to an attenuated increase in negative mood. This could possibly be related to the well\u2010known <jats:italic>positivity effect<\/jats:italic>, which suggests that older adults prioritize regulating their emotions to optimize well\u2010being. The results also highlight that caution is warranted when generalizing results from sleep deprivation studies across the adult lifespan.<\/jats:p>","DOI":"10.1111\/jsr.12801","type":"journal-article","created":{"date-parts":[[2018,12,26]],"date-time":"2018-12-26T01:59:18Z","timestamp":1545789558000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":65,"title":["Mood
