Hot Flashes, Anxiety, and Broken Sleep: The Perimenopause Trifecta

Your brain doesn’t shut down when you sleep. It activates a powerful cleaning system that clears toxins linked to Alzheimer’s disease. And for women over 40, hormonal changes make quality sleep harder — and more important — than ever. In this episode, Kristen Beasley dives into the first pillar of her Build Your Base framework: Prioritize Quality Sleep. You’ll learn how the glymphatic system works, why estrogen decline disrupts sleep architecture, and practical strategies to improve your sleep quality starting tonight. Kristen also shares how watching her father’s early Lewy Body Dementia symptoms — including REM sleep behavior disorder — shaped her understanding of why sleep is foundational to brain health. ⭐ What you’ll learn: • How the glymphatic system clears amyloid-beta during deep sleep • Why perimenopause disrupts your sleep stages • The role of cortisol and estrogen in sleep quality • How to use your Oura Ring or sleep tracker to measure improvement • Magnesium, sleep environment, and screen hygiene tips • What can REM sleep behavior disorder signal about brain health 🛍️ Products I Use and Recommend 🩸 Function Health — Test 100+ biomarkers twice a year — $25 off membership https://my.functionhealth.com/signup?code=KBEASLEY10&_saasquatch=KBEASLEY10&d=FHREF25 🌱 Adapt Naturals — Professional-grade foundational supplement stack — 20% off your first order https://www.adaptnaturals.com/KRISTEN80873 🌿 FullScript — My full professional dispensary for targeted supplements — special discount https://us.fullscript.com/welcome/healthylifeapproach 🔋 WHOOP 5.0 — Medical-grade recovery, strain, and sleep tracking — free band + one month free https://join.whoop.com/us/en/9302C0E0/ 💓 Pulsetto — Vagus nerve stimulation for HRV and parasympathetic recovery — special discount https://pulsetto.sjv.io/HealthyLife ☀️ Sunlighten — Infrared sauna therapy for detox, recovery, and cardiovascular health — special discount https://share.sunlighten.com/KristenBeasley Enjoyed This Episode?If this episode helped you, the single best thing you can do is subscribe, rate, and leave a review on Apple Podcasts or Spotify.
