Menstrual cycle-associated changes in reproductive hormones affect body temperature in women. We aimed to characterize the interaction between the menstrual, circadian, and scheduled sleep-wake cycles on body temperature regulation. Eight females entered the laboratory during the midfollicular (MF) and midluteal (ML) phases of their menstrual cycle for an ultradian sleep-wake cycle procedure, consisting of 36 cycles of 60-minute wake episodes alternating with 60-minute nap opportunities, in constant bed-rest conditions...

OBJECTIVES: Women with premenstrual dysphoric disorder (PMDD) experience disturbed mood, altered melatonin circadian rhythms, and frequent reports of insomnia during the luteal phase (LP) of their menstrual cycle. In this study we aimed to investigate nocturnal polysomnographic (PSG) sleep across the menstrual cycle in PMDD women and controls. METHODS: Seven PMDD women who indicated insomnia during LP, and five controls, spent every third night throughout a complete menstrual cycle sleeping in the laboratory...

A relationship exists between the sleep-wake cycle and hormone secretion, which, in women, is further modulated by the menstrual cycle. This interaction can influence sleep across the menstrual cycle in healthy women and in women with premenstrual dysphoric disorder (PMDD), who experience specific alterations of circadian rhythms during their symptomatic luteal phase along with sleep disturbances during this time. This review will address the variation of sleep at different menstrual phases in healthy and PMDD women, as well as changes in circadian rhythms, with an emphasis on their relationship with female sex hormones...
