Sleep in perimenopause isn’t just about winding down at night — it’s about what happens across the whole day. Three things I get clients to prioritise first:
1️⃣ Consistent wake time. Your circadian rhythm is set far more by light exposure at a fixed wake time than by when you go to bed. Waking at the same time daily (weekends included) stabilises melatonin timing and makes falling asleep easier over 1–2 weeks, even before you change anything else.
2️⃣ Blood sugar balance. Falling oestrogen affects insulin sensitivity, which can make overnight glucose dips more likely — and a dip can trigger a cortisol/adrenaline response that wakes you around 3–4am. A protein- and fibre-forward dinner, and avoiding a big sugar hit close to bed, helps keep that overnight curve steadier.
3️⃣ A proper wind-down routine. Perimenopause already lowers GABA-supportive progesterone, so anything that adds extra sympathetic stimulation before bed (screens, bright light, late intense exercise) works against you. A consistent cue-based routine — same order of steps each night — trains your nervous system to downshift faster.
None of these are quick fixes, but they compound. Which one do you already do — and which one’s missing? 👇
