The Science
Why You Can't Sleep — And Why It's Not Your Fault
Your Calm Switch Didn't Break. Your Hormones Stopped Supporting It.
Before menopause, your body had a built-in system for winding down at night. Progesterone — the hormone that declines during perimenopause and menopause — directly supported GABA, the neurotransmitter that tells your nervous system to stand down. GABA is your brain's off switch. It's what makes you feel calm, drowsy, and ready for sleep.
When progesterone drops, GABA activity drops with it. Your nervous system stops getting the signal to power down. That's why you feel wired at 3am even though your body is exhausted. It's why your brain won't stop replaying conversations from 2014. It's why the anxiety feels physical — heart racing, body buzzing, a sense of doom you can't explain.
That's not a sleep hygiene problem. That's a nervous system problem. And melatonin — which only regulates your sleep-wake cycle — was never designed to address it.
