Women report insomnia at higher rates than men, and the difference emerges around puberty. Sleep across the female lifespan is shaped by hormonal transitions, caregiving load, and under-recognition of sleep disorders in clinical settings.
Points of change
- Menstrual cycle. Many women report more disturbed sleep in the late luteal phase, alongside temperature and mood shifts.
- Fertility treatment. Medication effects, monitoring schedules, and psychological load all disrupt sleep.
- Pregnancy. Sleep architecture, physical discomfort, nocturia, restless legs, and increased risk of sleep-disordered breathing, particularly in the third trimester.
- Postpartum. Profound fragmentation, with bidirectional links between sleep disruption and perinatal mood disorders.
- Family sleep years. Parental sleep is often governed by a child's sleep, which makes family-level intervention more effective than individual advice.
- Perimenopause and post-menopause. Vasomotor symptoms, new-onset insomnia, and rising sleep apnea prevalence after menopause.
What good care looks like
CBT-I is effective across these stages, including in pregnancy and menopause, and is often preferable where medication is undesirable. Effective care also screens for sleep apnea rather than attributing all symptoms to hormones, and adapts protocols to caregiving realities — an unrestricted sleep window is not achievable for a postpartum parent, and the protocol should acknowledge that.
