Perimenopause doesn't just affect your hormones — it rewires your autonomic nervous system. Declining estrogen weakens the parasympathetic "brake" on your fight-or-flight response, leaving sympathetic activity elevated. Research links this shift to heart palpitations, poor sleep, anxiety, and the constant sense of being on edge. Cathy explains the science of perimenopause nervous system dysregulation and shares what the evidence actually supports for restoring balance.

Women are 40% more likely to develop depression during perimenopause — even with no prior mental health history. Estrogen withdrawal disrupts serotonin, dopamine, and GABA simultaneously: the three systems your brain relied on for emotional stability your entire adult life. Anxiety, rage, grey heaviness, and 3am dread are not a breakdown. They are neuroscience. Here's the hormonal mechanism, the window of vulnerability science, and the evidence-based protocol that actually he

At 43, I woke up anxious at 3am for months. My GP dismissed it. So I researched it myself — and found adaptogens. This is my honest, science-backed protocol: why perimenopause disrupts cortisol, why timing matters more than dosage, and exactly how I use ashwagandha KSM-66 and tulsi tea to sleep through the night again. Real results. No fluff.
