Sleep Support
Rest isn't a luxury, it's medicine.
If sleep has stopped working the way it used to, you are not failing. Your body is changing, and it deserves to be heard.
This is a soft place to land. Tell Keza what your nights actually look like and she will meet you where you are, no judgement, only evidence and care.
If you've been waking at 3am wondering what is wrong with you, nothing is. Your body is doing exactly what a perimenopausal, inflamed, over-asked body does in the dark. You are not broken. You are paying attention.
Up to half of perimenopausal women live with insomnia. Lost sleep raises cortisol, fuels inflammation, amplifies hot flashes, worsens insulin resistance in PCOS, and turns up the volume on pain. So when sleep frays, every other symptom gets louder, that is not in your head, that is biology. Which is also why protecting your sleep may be the single most loving thing you can do for the rest of your body this week.

Why your nights look the way they do
Tell Keza a few things above, and she'll show you the real reasons your nights feel the way they do, in your specific body, with your specific conditions.
What may actually help, and why
- 1
Blackout the bedroom
Even dim ambient light during sleep is associated with higher next-morning insulin resistance and lower heart-rate variability.
Why this may work for you: Your eyes detect light through your closed lids. Even hallway light or a streetlamp glow keeps melatonin partially suppressed all night and keeps your nervous system in low-grade alert mode. True darkness is biologically required, not aesthetic.

Fixed wake time, even on weekends
A consistent wake time is the single strongest circadian anchor and the foundation of CBT-I. Hold it regardless of how badly you slept.
Why this may work for you: Your internal clock is set by when you see morning light, not when you go to bed. A fixed wake time pins the whole system in place; everything else (bedtime, hunger, energy) follows. It is the one thing you can hold even on the worst nights.

These are self-management tools backed by peer-reviewed literature. If insomnia is severe and persistent, please speak with a healthcare provider. CBT-I therapy is available via telemedicine.
The five things with the strongest evidence (in plain language)
CBT for insomnia (CBT-I)
A short course of structured therapy that retrains the brain-bed relationship. A review of 11 trials in 973 women found it improves sleep more than sleep medication over the medium term. Why it works: it interrupts the conditioned arousal that makes your bed feel like a battleground.
Consistent wake time
The single strongest circadian anchor your body has. Hold it even on weekends, even after a brutal night. Why it works: your suprachiasmatic nucleus (your internal clock) takes its main cue from when you see morning light, not from when you go to bed.
Bedroom temperature 65–68°F (18–20°C)
Your core temperature has to drop by about 1°F to start sleep, and it rises in the luteal phase and across perimenopause. A cool room gives your body the heat sink it needs to fall asleep faster and stay asleep through night sweats.
Magnesium glycinate, 200–400 mg before bed
Pooled trials show ~17 minutes faster sleep onset and better sleep quality. Why it works: glycine itself lowers core temperature, and magnesium quiets the NMDA receptors your nervous system uses to keep you alert, together they hand your brain the off-switch.
Alcohol timing
Last drink at least 4 hours before bed; consider skipping it entirely the week before your period. Why this matters: alcohol sedates you into the first half of the night but blocks REM, then rebounds as a stimulant at 2–4am, exactly when perimenopausal women already wake.

Name one thing that raised your stress above 7 this week. Writing it externalises it, the first step in changing the pattern.
