How much we sleep at night is believed to impact next-day affective experiences. Yet, the existing research encumbered by methodological limitations. To address this issue harnessed experience sampling data (68,232 observations across 10,905 days) from 1,415 Belgian participants examine whether normal variations in duration linearly or nonlinearly influence fatigue, stress, happiness, anxiety, despondence, and calmness. We also tested people that less on average benefit more a standard increase than generally more. 10,080 models as part of multiverse analyses non-pre-registered study. Findings indicate even small increases promote (albeit, way) positive experiences, effects are stronger period after waking relative later day, effect magnitudes differ markedly tentatively fatigue feelings despondence soon may be greater for average. However, little support was gained being nonlinear. In short, our findings advance understanding what extent impacts various reveal range important nuances relationship.
