When Sleep Isn't Perfect: Risk and Resilience for Cognitive Consquences of Imperfect Sleep Duration and Suboptimal Timing of Tasks in Circadian Rhythm
Abstract
We have made significant progress in our work with the industry collaborator providing data to meet our study aims. Preliminary analyses of sleep and cognitive performance data have yielded compelling findings with respect to sleep duration and cognitive performance across the lifespan. These now published findings demonstrated an inverse U-shaped relationship between typical sleep duration and cognitive performance on three internet-based cognitive tasks. We demonstrated peak performance occurred at 7 hours sleep duration in younger and middle-aged individuals. We also demonstrated that declines in performance beyond the peak were as steep, if not steeper, in younger as compared to older individuals. These findings were contrary to expectation, given the long-held assumption that younger individuals need more sleep to perform at their peak and the assumption that the relationship between cognitive performance declines and longer sleep durations are due to age-related medical comorbidities.
