Dr. Andrea Matsumura: The Hormonal Sleep Connection: Women’s Sleep, Menopause, Insomnia, Circadian Health, Changes, and Restorative Rest

The Hormonal Sleep Connection explores the powerful relationship between women's hormones, the brain, circadian rhythms, and restorative sleep. During perimenopause and menopause, changes in estrogen and progesterone can affect temperature regulation, nighttime stability, mood, mental clarity, and the ability to maintain consistent rest. This book provides a clear, science-informed look at why these changes happen and how sleep can be supported through practical, sustainable habits.Inside, readers will discover how hormonal signals influence sleep quality, why sleep patterns change across different stages of womanhood, and how stress and heightened alertness can reinforce nighttime wakefulness. The book also examines the role of the nervous system, sleep architecture, memory, emotional regulation, metabolism, immune function, and the body's internal clock. Readers will learn about: The connection between estrogen, progesterone, and sleep Why night sweats and temperature changes can interrupt rest How menopause may influence sleep architecture and recovery The relationship between stress, nervous-system activity, and insomnia How light exposure and daily timing influence circadian rhythms Why consistent routines can support healthier sleep patterns How restorative sleep differs from simply spending time in bed The connection between sleep, memory, mood, metabolism, and cognitive function Practical principles for supporting deeper and more consistent rest How to adapt sleep practices as hormonal needs change Ways to build sustainable habits around light, movement, timing, and relaxation How to create a personalized framework for long-term sleep and circadian health Rather than presenting sleep as a problem with one simple solution, The Hormonal Sleep Connection takes a whole-system approach. Hormones, the brain, nervous system, circadian rhythm, environment, daily behavior, and emotional state all contribute to the quality of nighttime recovery. Whether sleep has become more unpredictable during midlife or you simply want to understand the science behind healthy rest, this book offers a practical framework for understanding what may be happening and creating conditions that better support the body's natural sleep processes. Better sleep begins with understanding the signals your body is sending-and learning how to work with them.
