Ep 54: This Girl Is on Fire (in the Middle of Winter): Hot Flashes Explained

It may be freezing outside — but if you’re in midlife, it might feel like your body is on fire. 🔥 In this episode of Hump Day Hormones, we continue our Head-to-Toe Menopause Series by turning up the heat and tackling one of the most misunderstood (and dismissed) menopause symptoms: hot flashes. If you’ve ever gone from “I’m fine” to “why am I radiating like a space heater?” in under 30 seconds — this episode is for you. We break down: • Why hot flashes start in the brain, not just the ovaries • How estrogen stabilizes your internal thermostat — and what happens when it drops • Why hot flashes are neurologic and vascular events, not just “being warm” • The role of KNDy neurons and why they’re the real stars of the show • Why you can swing from sweating to shivering within minutes • The difference between hot flashes and histamine flushing • Why night sweats are especially disruptive to sleep, cortisol, and metabolism And here’s where it gets really important: Hot flashes may be an early signal of vascular stress. They don’t cause heart disease — but growing evidence shows they may act like a check-engine light for cardiovascular health during menopause. We also cover: • The connection between hot flashes, cortisol, insulin resistance, and inflammation • Why more severe or frequent hot flashes deserve attention — not dismissal • FDA-approved hormonal treatments and why they work so well • Non-hormonal treatment options (SSRIs, gabapentin, and newer neurokinin-3 receptor antagonists) • What lifestyle strategies help — and what won’t fix the root cause Bottom line: Hot flashes are real, biologically meaningful, and treatable. They are not “just in your head,” not something you have to live with, and not a rite of passage you’re meant to suffer through. Your body is communicating with you — and it deserves to be listened to.
