How to Manage Perimenopause Hot Flashes
Hot flashes (and their nighttime form, night sweats) are the most disruptive and most trackable symptom of perimenopause. They're driven by your hypothalamus misreading body temperature as estrogen drops. The good news: they're often very responsive to intervention.
Lifestyle and nutrition (start here)
- Reduce alcohol — the single biggest trigger for most women
- Stable blood sugar — avoid naked carbs; pair with protein
- Limit caffeine after noon
- Layer your clothing — cotton, breathable
- Cool the bedroom — 18°C / 65°F is ideal
- Identify your food triggers — spicy food, sugar spikes, and aged cheese are common
Supplements with reasonable evidence
- Magnesium glycinate (200–400mg, evening) — sleep + may reduce night sweats
- Vitamin E (modest effect on hot flash frequency)
- Black cohosh (mixed evidence, check with clinician)
Prescription options
- HRT — gold standard for moderate-to-severe vasomotor symptoms
- Fezolinetant (Veozah) — non-hormonal, FDA-approved for hot flashes
- SSRIs / SNRIs (low dose) — can reduce hot flashes
- Gabapentin — useful for night sweats specifically
If hot flashes are disrupting sleep or daily life, telehealth platforms like Midi Health, Alloy, or your GP can assess HRT and non-hormonal options.
Track to see what's working
Hot flashes are perfect for tracking — frequency, intensity, time of day, and what you ate or did in the hours before. Patterns emerge in 1–2 weeks.
