Article of Interest

• Declining estrogen and progesterone levels can affect body temperature regulation and sleep architecture.
• Night sweats and hot flashes frequently cause nighttime awakenings.
• Mood changes and anxiety can further disrupt sleep continuity.
• Consistent routines, a cool sleep environment, and evidence-based behavioral strategies may help improve rest.

• (NIH/PubMed — Tandon VR et al., 2022, review)
  Sleep disorders affect 16–47% of perimenopausal and 35–60% of postmenopausal women, with insomnia and vasomotor symptoms as primary drivers. Hormonal changes, including decreased melatonin and estrogen, contribute to longer sleep latency and more awakenings.
• (NIH/PubMed — Skibiak K et al., 2025, narrative review)
  Poor sleep quality and insomnia worsen across menopausal stages, with higher risks of obstructive sleep apnea and reduced total sleep time in postmenopausal women, even without hot flashes.
• (NIH/PubMed — Smith RL et al., 2018, Midlife Women’s Health Study cohort)
  Vasomotor symptoms and depression are strongly associated with higher rates of insomnia during the menopausal transition.
• (NIH/PubMed — McCurry SM et al., 2016, randomized controlled trial)
  Telephone-delivered cognitive behavioral therapy for insomnia (CBT-I) significantly improved sleep quality and reduced insomnia severity in perimenopausal and postmenopausal women experiencing hot flashes.

Additional Studies

• (ClinicalTrials.gov — NCT07375095, completed 2024)
  A randomized, double-blind, placebo-controlled trial evaluated a daily dietary sleep supplement in perimenopausal and postmenopausal women (ages 40–65) with moderate sleep disturbance. Results have not yet been posted publicly, so no conclusions about effectiveness can be drawn at this time.
• (ClinicalTrials.gov — NCT06306404, starting soon)
  Researchers are preparing this study to examine whether menopausal hormone therapy, online cognitive behavioral therapy for insomnia (CBTi), or a combination of both can help reduce insomnia severity and other menopausal symptoms in perimenopausal women. The trial is starting soon, so no results are available and no conclusions can be drawn at this time.
• (ClinicalTrials.gov — NCT02835261, completed 2021)
  A randomized crossover study investigated the effects of mild sleep restriction on cardiometabolic risk factors in pre- versus postmenopausal women. Some related findings on blood pressure and other markers have been published, but specific implications for treating menopausal sleep problems require further review.

Interpretation: Published reviews and cohort studies consistently show that sleep disturbances increase during the menopause transition, primarily due to hormonal shifts and vasomotor symptoms. Non-pharmacological interventions such as CBT-I have demonstrated support in randomized trials for improving sleep quality.

Limitation: Many findings rely on self-reported measures. Individual variability is high due to comorbidities, lifestyle, and other factors. Data from studies that are completed but have not yet posted results, or from ongoing trials, cannot be used to draw firm conclusions about effectiveness or safety at this time. Long-term effects of combined lifestyle approaches need more research.

Evidence Strength: Moderate to Strong / Reviews, Prospective Cohort Studies, and RCTs (consistent prevalence patterns; good interventional support for CBT-I)

The Real Takeaway

• Sleep problems increase during menopause mainly due to hormonal changes and night sweats.
• Consistent sleep routines, a cool bedroom, and daytime exercise are among the most practical supports.
• Avoiding late caffeine and alcohol can significantly improve sleep continuity.
• Behavioral strategies like CBT-I show strong research support.
• If sleep issues persist, consult your healthcare provider.
