Why do so many women suddenly start waking up at 3:00 a.m. during perimenopause? In this practical and science-backed conversation, Dr. Mariza sits down with renowned sleep specialist Dr. Michael Breus to unpack why sleep changes so dramatically during perimenopause and menopause, and what women can do to finally get restorative sleep again. Dr. Breus explains how fluctuating estrogen, progesterone, melatonin, cortisol, body temperature, and blood sugar all collide during midlife, creating the perfect storm for middle-of-the-night awakenings. He shares why waking up at 3:00 a.m. is incredibly common, how modern habits often make it worse, and why women need a layered approach instead of relying on a single solution. Together, they discuss everything from sleep apnea, hormone replacement therapy, alcohol, caffeine, blood sugar, and evening routines to cognitive behavioral therapy for insomnia (CBT-I), breathwork, thermoregulation, and supplementation. Most importantly, Dr. Breus offers practical strategies women can begin implementing immediately to improve sleep quality, reduce nighttime wakeups, and build a foundation for better health through every stage of menopause. If you've been lying awake at 3:00 a.m. wondering what's happening to your body, this episode is packed with answers and actionable solutions. DR.
