#229: How To Legally Boost Hematocrit, Limit The Damage From Night Shift Work, The Dangers Of Vasectomies and More!

My guest on today’s show, Maria Ensabella, is the co-author of ReInventing Cool: How to Make COLD Your Best Ally Against Inflammation, Pain, and Aging, written alongside Antra Getzoff. This groundbreaking new book explores how strategic cold exposure can radically transform your health. In this episode, you'll get to explore what really happens when your body is exposed to sub-zero temperatures—and how that intense, brief burst of cold triggers a powerful fight-or-flight response that boosts circulation, oxygenates your blood, flushes out toxins, and floods your system with endorphins. You’ll also learn how these effects can lead to reduced inflammation, faster recovery, and even better mental clarity. Additionally, we'll break down how cryotherapy compares to cold water immersion, answering your burning questions about which method is better for pain relief, inflammation, and overall rejuvenation. Plus, Maria shares practical tips, client stories, and surprising benefits of cold exposure, including its role in improving sleep and reducing stress. Whether you're a seasoned cryotherapy enthusiast or new to the concept of harnessing cold for health benefits, this episode will provide valuable information and leave you inspired to explore the chillier side of health optimization.

Hypertension isn’t a snapshot—it’s a movie, and most of us are missing the plot. Technology can outpace tradition when it’s patient-first, not doctor-first. This conversation will break new ground by flipping the hypertension narrative from a dry medical topic to a human behavior puzzle—cracking why we ignore what kills us and how tech can jolt us awake. Unlike other podcasts where Dr. Shah might recite Hilo’s specs or his CV, here he’ll wrestle with the messy realities of healthcare inertia, his own career gamble, and the psychology of change. The fresh angles—his pivot story, the unseen patient barriers, the next wearable frontier—will spark revelations Jay hasn’t unpacked elsewhere.
