Full Show Notes: https://bengreenfieldlife.com/lnsleepspace/ We’ve all felt it—one late dinner, a couple of drinks, or a blue-lit night on the laptop, and suddenly your sleep goes sideways. In this Best of LIFE Network Experts episode, I’m joined by Dr. Daniel Gartenberg—a sleep scientist and CEO of SleepSpace—to dive into the physiology of deep sleep, recovery, and the modern habits that disrupt them. Dr. Gartenberg’s research—funded by the National Science Foundation and National Institute on Aging, and applied within the Navy and Air Force—is redefining how we understand recovery, performance, and brain optimization. We explore: - Why alcohol, heavy meals, and late nights destroy deep sleep. - Why teens naturally become “night owls”—and how artificial light makes it worse. - How temperature, cooling devices, and even warming your hands can trigger faster sleep onset. - How every species uses sleep to conserve energy, balance hormones, and clear the brain. - How CBT-I (Cognitive Behavioral Therapy for Insomnia) retrains your brain better than drugs. - What the connection between oral posture and airway health reveals about deep rest. - What the SleepSpace smart bed and app can teach you about sound, light, and vibration-based recovery—no wearables required.
