Dr. Leland Stillman is one fascinating doctor and a man after my own heart...meaning he's interested in everything from how polar bears use cold thermogenesis and hibernation to enhance longevity to how your environment drastically shapes your health no matter how hard you exercise or how perfectly you eat. (http://stillmanmd.com/) Early on, Leland was drawn to natural and integrative medicine. After majoring in environmental health at Connecticut College and earning his medical doctorate from the University of Virginia School of Medicine, Leland completed his training in internal medicine at Maine Medical Center. Board-certified in internal medicine and specializing in integrative medicine, he is dedicated to doing whatever it takes to discover the root cause of his patients' medical problems through advanced laboratory testing, and then addressing those imbalances with dietary or lifestyle interventions. Leland focuses not only on the patient but on all aspects of the environment they live in. Some of Leland's professional interests include phototherapy (photobiomodulation), nutrition, toxicology, and the immune system. And in this episode, recorded during a chilly walk in Spokane, Washington - combined with a "make-up" recording of the latter half from my home studio treadmill - we dive right back into some of that content and so much more.
