STUDY OBJECTIVES: The maternal postpartum period is characterized by @entity1949 , which is associated with @entity73 , @entity146 , and changes in @entity2493 patterns. In addition to @entity1949 , @entity1 undergo a complex set of physiological and environmental changes upon entering the postpartum period, confounding our understanding of effects of postpartum @entity25 . The primary study aim was to understand the basic impact of a single night of postpartum-like @entity1949 on @entity25 , nocturnal @entity2493 levels, mood, @entity25 , and neurobehavioral performance. MEASUREMENTS AND RESULTS: For one week prior to entry into the laboratory, eleven healthy nulliparous @entity1 kept a stable sleep-wake schedule (verified via actigraphy). @entity1 contributed three consecutive nights of laboratory overnight polysomnography: (1) a habituation/ @entity25 screening night; (2) a baseline night; and (3) a @entity1949 night, when @entity1 were awakened three times for ~30min each. Self-reported sleep quality and mood (Profile of Mood States survey) both decreased significantly after @entity1949 compared to baseline measurements. Unexpectedly, @entity25 (Multiple Sleep Latency Test) decreased significantly after @entity1949 . @entity1949 had no significant effect on time spent in nocturnal sleep stages, urinary @entity12604 concentration, or psychomotor vigilance test performance. @entity1 continued to provide actigraphy data, and daily PVTs and self-reported sleep quality assessments at home for one week following @entity1949 ; these assessments did not differ from baseline values. CONCLUSIONS: While there were no changes in measured physiological components of a single night of postpartum-like experimental @entity1949 , there were decreases in self-reported measures of mood and sleep quality. Future research should examine the effects of multiple nights of modeling postpartum-like @entity1949 on objective measures of sleep and daytime functioning.
