Adequate sleep is essential for general healthy functioning.
This paper reviews recent research on the effects of chronic sleep restriction on neurobehavioral and physiological functioning and discusses implications for health and lifestyle.
Restricting sleep below an individual’s optimal time in bed (TIB) can cause a range of neurobehavioral deﬁcits, including lapses of attention, slowed working memory, reduced cognitive throughput, depressed mood, and perseveration of thought.
Neurobehavioral deﬁcits accumulate across days of partial sleep loss to levels equivalent to those found after 1 to 3 nights of total sleep loss. Recent experiments reveal that following days of chronic restriction of sleep duration below 7 hours per night, significant daytime cognitive dysfunction accumulates to levels comparable to that found after severe acute total sleep deprivation. Additionally, individual variability in neurobehavioral responses to sleep restriction appears to be stable, suggesting a traitlike (possibly genetic) differential vulnerability or compensatory changes in the neurobiological systems involved in cognition.
