Sleep and Mood During Pregnancy and the Postpartum Period.

During the perinatal period, compromises in sleep duration and quality are commonly reported by women and confirmed by objective measurements of sleep. Self-reported poor sleep has been associated with concurrent mood disturbance and with increased risk for future mood problems during pregnancy and the postpartum period. Findings on the relationship between objectively measured sleep and mood in perinatal women have been mixed. This article reviews the literature on the nature of and contributing factors to perinatal sleep disturbance, the relationship between sleep and mood, and intervention studies that aim to improve maternal sleep.
