The 3 a.m. Wake-Up: Blood Sugar and the Hormone Ladder

Why do so many women wake at 3 a.m. — alert, restless, and unable to fall back asleep? In this episode, we unpack the glucose-regulation ladder — the sequence of hormones the body releases when blood sugar drops. From insulin and glucagon to norepinephrine, adrenaline, and cortisol, each plays a role in nighttime wake-ups, midlife crashes, and metabolic instability. You’ll learn how refined carbohydrates and alcohol trigger different correction pathways, why muscle mass protects you, and why chronic cortisol correction can gradually reduce resilience. This episode reframes middle-of-the-night waking as a physiological phenomenon — not a personal failure. Regulation begins with stability.
