If you’re a woman in your 40s or 50s who keeps waking up at 2–4 AM, you’re not imagining things — and you’re not “just stressed.” Research shows that 52% of women entering perimenopause experience early-morning awakenings, often long before hot flashes or irregular periods begin. What’s happening is deeply physiological: declining estrogen disrupts the brain’s regulation of melatonin, cortisol, and body temperature. That 3AM wake-up? It’s often a cortisol spike, not anxiety you created out of nowhere. Women tell me: “I wake up feeling like someone hit a switch.” “I’m exhausted but wide awake — and I feel alone.” You’re not alone. And you’re not broken. What actually helps (evidence-based): Studies show 300mg magnesium glycinate at night can reduce nighttime awakenings. Women who keep their bedroom < 67°F (19°C) report 42% fewer sleep disruptions. Cognitive behavioral strategies for insomnia (CBT-I) reduce wake-after-sleep-onset by up to 60%. Your body isn’t betraying you — it’s signaling transition. And transition is something you deserve support in, not silence. Tags: #Health #SleepHealth
