Short answer: Night-dominant vasomotor symptoms respond to bedtime-weighted treatment: micronized progesterone or gabapentin at night, transdermal estradiol for continuous coverage, or fezolinetant when hormones are unsuitable. Cooling strategies help at the margins but do not replace treatment.
Bedtime-weighted options
- Micronized progesterone 200–300 mg at bedtime — sedating and endometrium-protective.
- Gabapentin at night — reduces nocturnal events and deepens slow-wave sleep.
- Transdermal estradiol — steady 24-hour levels, no overnight trough.
- Fezolinetant — hormone-free, separates from placebo within the first week.
Environmental measures worth doing
- Bedroom at 16–18 °C; a cool room genuinely widens the thermoneutral margin.
- Layered, moisture-wicking bedding rather than a single heavy duvet.
- No alcohol within three hours of bed.
- A cool shower before bed lowers core temperature on the rebound.

Frequently asked questions
Why are my flashes worse at night?
Core temperature falls overnight and the thermoneutral zone narrows further, so a smaller temperature rise triggers a full heat-dissipation response.
Can I treat only at night?
Yes for gabapentin and progesterone. Estradiol and fezolinetant provide continuous coverage and are dosed accordingly.
