Across 62 hours of total sleep deprivation in a controlled laboratory environment, positive affect as measured repeatedly with the positive and negative affect schedule (PANAS) scale decreased significantly, and was modulated by circadian rhythm. Negative affect showed the inverse pattern. Subjective sleepiness predicted PANAS scores, suggesting shared underlying mechanisms.
