In this “Best of LIFE Network’s Experts” episode with Dr. Dan Gartenberg, you’ll get to discover the fascinating science behind how sleep truly works—and why it’s one of the most powerful levers for improving health and performance. You’ll learn how alcohol, heavy meals, and irregular sleep schedules disrupt deep rest, why teenagers naturally become “night owls,” and how temperature regulation, light exposure, and bedtime routines shape sleep quality. Dr. Gartenberg also breaks down CBT-I (Cognitive Behavioral Therapy for Insomnia), a proven, non-drug approach that retrains your brain to overcome sleeplessness. Along the way, you’ll explore how airway health, magnesium, GABA (gamma-aminobutyric acid), CBD (cannabidiol), and melatonin influence rest, plus cutting-edge tools like the SleepSpace smart bed that personalize recovery. Whether you’re optimizing performance, balancing hormones, or simply tired of waking up groggy, this episode gives you research-backed strategies to finally master your sleep.
Dan is a sleep scientist with a Ph.D. in cognitive psychology, currently the CEO of SleepSpace, and an adjunct professor at Penn State University in the Department of Biobehavioral Health. With 15 years under his belt developing sleep technology, and a resume working for artificial intelligence groups in the Navy and the Air Force, Dan has garnered more than $3.5 million in grant awards from the National Science Foundation and the National Institute of Aging. The purpose? To address a problem that affects not just the developed world, but billions around the globe: poor sleep quality.
Dan's stated magnum opus is to develop the ultimate connected smart bedroom where natural remedies like sound, light, and vibration are used synergistically with various wearables and “nearables” (small, wireless devices in the room not attached to you) to diagnose and treat sleep disorders and improve the sleep quality of every human being.
His current focus is on improving insomnia and sleep apnea outcomes, which contribute to Alzheimer’s disease and heart disease. The digital health technology created by Dan and his team is currently not for medical use, meaning it is available to the general public. People like you or me can access direct interventions on a nightly basis, including the best meditations to stop a racing mind, a network of coaches who specialize in all aspects of sleep, and the Dr. Snooze AI, which features in the SleepSpace app.
As an inventor with five patents, Dan is a highly innovative creator with a superior understanding of sleep disorders compared to the vast majority of other experts. With over 10 peer-reviewed publications and a viral TED Talk with over 5 million views, Dr. Gartenberg and his technology have been featured on The Today Show, Gizmodo, New York Times, The Washington Post, Quartz, NPR, Pop Sugar, CNN Business, Reuters, Get The Gloss, Marie Claire, Discoveries and Breakthroughs Inside Science, DC Inno, APA Magazine, Apartment Therapy, Sleep Review Magazine, Entrepeneur, Business Insider, Lonely Planet, and App Picker.
His SleepSpace app (referenced in this show) helps you:
- Track your sleep using any smartphone (iOS or Android).
- Improve rest through sound, light, and vibration-based feedback.
- Integrate seamlessly with major wearables such as Oura, Whoop, Apple Watch, Biostrap, Garmin, and Eight Sleep.
