Is this normal?
Why am I waking up at 3am every night?

Yes — mid-night waking, especially between 2 and 4am, is one of the most commonly reported perimenopause sleep patterns. It's often tied to a nighttime dip in estrogen and progesterone, a small vasomotor event you may not fully register, or a rise in cortisol at that hour. You are not alone, and it is not a personal failing.
Why it happens
- Progesterone has a calming, sleep-supporting effect; its decline in perimenopause reduces sleep depth.
- A subclinical hot flash — one that doesn't fully wake you as 'hot' — can pull you out of REM.
- Cortisol naturally rises in the early morning hours; when the transition amplifies it, you wake fully alert.
- Anxiety and rumination cycles are more common in the transition and thrive at 3am.
When it's not just menopause — see a provider
- Loud snoring, gasping, or witnessed pauses in breathing — screen for sleep apnea.
- Waking short of breath, with chest discomfort, or with heart racing (see 'heart palpitations' page).
- Waking with panic or persistent low mood — mention to a provider.
- Untreated pain (joint, back) that consistently wakes you.

Frequently asked
Is it hormonal or is it stress?
It's usually both. Hormonal shifts lower the threshold at which stress or a small physical trigger can wake you.
Will melatonin help?
Melatonin timing and dosing is individual and should be discussed with your provider — Dot is educational and does not recommend supplements or medications.
Is going back to sleep even possible?
For many women, yes — with consistent wind-down routines, cooler room temperatures, and treating any underlying vasomotor or anxiety pattern. A provider can help with specifics.
