Episode Overview:

Through the story of five and a half years of broken sleep from night feeding and breastfeeding — and the specific cognitive and physical toll that followed — Frances explains the architecture of sleep: what the four stages are, what each one does, and why slow wave sleep (the most physically restorative stage) is the one most vulnerable to disruption. She connects this to the perimenopause picture almost nobody explains — that progesterone declines before oestrogen, and progesterone is what protects slow wave sleep, which is why sleep is often the first perimenopause symptom. And she describes what gradually returned when the circadian work began.

 

In This Episode You'll Learn:

•       Why you can sleep eight hours and still wake unrested — and what's actually happening during those hours

•       The four stages of sleep and what each one specifically does — including the one that physically rebuilds you

•       Why slow wave sleep is concentrated in the first half of the night — and why this matters enormously for anyone whose early sleep is disrupted

•       What years of interrupted night sleep does to the nervous system — and why it stays light even after the disruption ends

•       Why mum brain is partly a slow wave sleep story — the cognitive signature of years of fragmented early-night sleep

•       Why progesterone declines before oestrogen in perimenopause — and why this makes sleep the first perimenopausal symptom, often years before anything else changes

•       Why the 2–4am waking feels different from other wakings — and what the cortisol curve has to do with it

•       Why alcohol disrupts slow wave sleep even in moderate amounts

•       What Frances noticed returning, gradually, over months of consistent circadian work

 

Key Topics Discussed:

•       The four sleep stages — light sleep (Stages 1 and 2), slow wave/deep sleep (Stage 3), REM sleep

•       What slow wave sleep specifically does: growth hormone release, immune function, cellular repair, cognitive restoration, brain waste clearance

•       Sleep distribution across the night — why the first half and second half are fundamentally different

•       Nervous system adaptation to years of broken sleep — why lightness persists after the cause is gone

•       The progesterone-slow wave sleep connection — the perimenopause sleep chapter nobody explains

•       Oestrogen's later role — sleep architecture, temperature regulation, cortisol pattern

•       Practical interventions: morning light, wake time consistency, evening darkness, meal timing, temperature, alcohol
