Show Notes
Today we welcome back Dr. Charles Raison to this Sauna Talk podcast part 2. I encourage you to check in with Part one, where Chuck and i work from the starting block about Sauna health benefits and research surrounding hypethermia and hot/cold contrast therapy. In this episode, by design we go deeper. We unpack hot cold therapy as a novel treatment for mental health. 101.3 101.3 isn't just the radio frequency for a hit music station in the Twin Cities. We have foundational research surrounding the effects on the body and the mind of achieving this core body temperature. Ashley Mason's work at University of California San Francisco is expanding upon the psychological and physiological effects of this level of heat stress when reaching this core body temperature. Physically, from, for example the standpoint of blood pressure and heart rate variability. Yet how do these physical changes affect people's moods? Specifically, as a possible novel treatment in the area of depression, anxiety, and other mental health issues. Totonu The Japanese have a word for that nirvana feeling we get after a few sauna rounds and cold therapy action. They call it Totonu. And there is actually a published study on the neuro effects of sauna bathing. We link to this study on the Sauna Research Institute website as well as on SaunaTimes websites. In the study, it is recognized that sauna is an activity that promotes relaxation and health. Three cycles of sauna, cold, rest lowers your heart rate and makes you feel more relaxed. Intense feelings of happiness have been reported shortly after enjoying a hot sauna and cold water, what is known in Japan as the "totonou" state. With this contrast therapy, we achieve a lower heart rate, changes of brain waves, and better metabolic health through the increase in brown fat production – known as "the good fat". And one could argue that, for those horizontally challenged, sauna use raises heart rate to about the state we achieve with a fast walk. So there is a weight loss association to regular sauna use. But this is not something i'd get the scale out to rely upon. The Vail Project – Eagle Valley We discuss a "Top Flight Sauna" for Vail Health's Behavioral Health Innovation Center. Right now in development, the CHILL'D Study ("Cold and Heat Investigation to Lower Levels of Depression") will explore ways to optimize the proven benefits of hyperthermia for depression, including whether adding cold to heat will improve outcomes and whether hyperthermia can be effectively combined with standard antidepressants. Vail Health is especially interested in thermic bathing within ancient practices. Many of us listening enjoy Nordic style sauna, where we pay homage to the origins of the word sauna (Finland). And sometimes many spend a lot of effort scolding its improper pronunciation. Yet, for those of us that share and know that good feeling, the definition of sauna is arguably much more important than its pronunciation. And for that matter, the definition of sauna is universal and straightforward: Sauna Definition: A room, often lined with wood, with a heat source that heats rocks to sufficient temperature to create steam when water is tossed on rocks. So, for example, Temascal, Native American Sweat Lodge, Banya and venik treatments, are all ancient sauna sweat bathing practices. Chris Lindley is Chief Population Health Officer, Vail Health and the Executive Director, Eagle Valley Behavioral HealthExecutive Director at Eagle Valley Behavioral Health. I will save his bio for what I hope to be a dedicated podcast interview with Chris. But a quick note: Chris's education and passion revolve around improving the population's health, emergency response, and wellness. Chris is a decorated combat veteran, receiving a Bronze Star and Presidential Citation while leading troops in Iraq in 2005.

What happens when two lifelong sauna enthusiasts, longtime friends, and thermal soul brothers decide to write a book celebrating sauna culture? In Sauna Talk Episode 142, Glenn Auerbach sits down with Tom Rolando at Sauna Days 2026, on the shores of Lake Superior at Larsmont Cottages, to introduce their new book, Sauna Life: From Heat Up to Cool Down. This conversation is especially meaningful because Tom was the very first guest on Sauna Talk. Now, 142 episodes later, they're back together, sharing stories, laughs, and reflections on a friendship that helped inspire not only the book but Sauna Days itself. Sauna Life is more than a coffee table book. It's a celebration of the sauna community. Three years in the making, the book brings together hundreds of photographs, personal stories, and reflections from sauna enthusiasts around the world. Organized around six contrasting themes — Heat, Cold, Nature, Build, Friendship, and Solitude — it captures the beauty, simplicity, and shared experiences of authentic sauna culture. Recorded live before a Sauna Days audience, Glenn and Tom explore: How their friendship began with a wood-fired sauna build.
Something special is happening in the world of sauna research. In this episode of Sauna Talk, Glenn Auerbach takes us to The Well in Norway, where the Sauna Research Foundation has brought together 15 researchers from nine countries to advance the science of sauna bathing. For years, researchers studying sauna and its potential health benefits have often worked independently, across different countries and scientific disciplines. Now, they're coming together to share ideas, challenge assumptions, establish common research standards, and build a foundation for future collaboration. With his handheld recorder, Glenn captures spontaneous conversations in the hallways of this international gathering. We hear directly from researchers studying cardiovascular health, cardiac rehabilitation, mental health, stress, sleep, and the physiological mechanisms behind sauna's potential benefits. Among the voices featured are Earric Lee of the Montreal Heart Institute, Sam Oliver of Bangor University in Wales, Norwegian researchers Rune Jonasen and Eva Hillan, and Sauna Research Foundation board members John Sabes and Hans Hägglund. The conversations range from clinical research protocols and long-term health studies to wood-fired saunas, Norway's floating sauna culture, and the importance of simply enjoying the sauna experience. And perhaps one of the most memorable insights comes from Rune Jonasen, who suggests that sometimes the best part of sauna isn't the heat itself. It's waking up in the morning knowing that today is a sauna day. What makes this gathering remarkable isn't just the science. It's the openness, trust, and collaborative spirit among researchers who share a common interest in understanding sauna and its place in our lives. This episode captures an important moment in the evolution of sauna research, told through the voices of those helping move it forward.

In this episode of Sauna Talk, Glenn Auerbach sits down with Risto Elomaa, outgoing president of the International Sauna Association, on the eve of the International Sauna Congress in Oslo. After 16 years as ISA president—and two decades on its board—Risto reflects on a lifetime shaped by sauna, beginning with his first smoke sauna at just four weeks old. He shares stories from decades of sauna culture around the world, from Finland and Germany to Japan, South Korea, China, and beyond. The conversation explores what defines a real sauna, the importance of good löyly, European sauna standards, the future of sauna research, and why Risto believes researchers need common protocols if sauna science is going to advance responsibly. Glenn and Risto also discuss Sauna Aid and its work supporting Ukraine, the growth and regulation of Aufguss, sauna diplomacy, birch vihta traditions, raising children with sauna, smoke sauna culture, and some of the memorable people Risto has met on sauna benches around the world. And when asked what matters most in a good sauna? For Risto, the answer is simple: good löyly, good löyly, and good löyly. Join us for a wide-ranging conversation with one of the most influential international voices in modern sauna culture as he prepares to pass the torch at the International Sauna Congress.

What happens when we stop performing and start remembering who we actually are? In this live conversation from Sauna Days 2026, Glenn Auerbach sits down with longtime friend Harvey Martin for a wide-ranging Sauna Talk about performance, identity, intuition, nervous-system regulation, and the role sauna can play in bringing us back to ourselves. Harvey has spent years inside the world of high performance. After playing professional baseball, he worked in player development and spent four seasons doing human performance coaching with the San Francisco Giants. Today, he works privately with elite athletes, musicians, and other high-level performers navigating pressure, identity, and life beyond the performance itself. But Harvey came to Sauna Days with one word on his mind: Remembrance. Remembering who we are underneath the noise. Underneath the information. Underneath the algorithms, expectations, status, and constant pressure to perform. Glenn and Harvey explore what happens when a profession becomes an identity, why facts alone rarely change human behavior, the difference between performance and presence, and why intuition becomes increasingly important in a world built around information and algorithms. And, naturally, they bring it back to sauna. Harvey shares the story of his wood-fired horse trailer sauna in Arizona—with an office in the front and hot room in the back—and why building a fire, tending it throughout the day, and making your own heat forces you to slow down. As Harvey puts it, there's something different about heat you make yourself. In this episode: • Harvey's journey from professional baseball to the San Francisco Giants • Working with elite athletes and musicians under extreme pressure • Separating performance from identity • Why emotional experience changes behavior more than information • Intuition, presence, and nervous-system regulation • What algorithms may be doing to our awareness • Sauna as a practice of remembrance • Why wood-fired sauna naturally slows us down • Harvey's Arizona horse trailer sauna and writing space • The value of making your own heat • Why sometimes "it takes all day to live" Recorded live at Sauna Days 2026.

This episode of Sauna Talk is supported by Kuuma Sauna Stoves, built by Lampa Manufacturing in Tower, Minnesota. Until next time, we'll see you on the bench.
In Sauna Talk Episode 138, Glenn sits down with longtime friend and fellow "thermal soul brother" Jeff Pyzyk—a Wisconsin sauna enthusiast with more than two decades of experience and an estimated 3,500+ sauna sessions under his belt. Jeff shares how one lakeside sauna and a cold plunge in 1998 turned into a lifelong pursuit. From building his own saunas and experimenting with wood-fired heat to helping inspire the low-profile Kuma stove, Jeff has developed his perspective the old-fashioned way: through years of time on the bench. The conversation moves from good heat, löyly, rock mass, bench height, and cold plunging into some unexpected territory: pizza, espresso, vintage Volkswagens, and why hands-on experience matters more than internet theory. At the center of it all is Jeff's simple message to anyone suffering from sauna analysis paralysis: There is no perfect sauna. Build your damn sauna. Glenn and Jeff also talk Sauna Days, friendship, the growing North American sauna community, and that special moment a few rounds into a sauna session when the fire settles, the rocks are hot, and everything just clicks. This episode is sponsored by Sauna Build: From Start to Finish by Glenn Auerbach. If you've been thinking about building your own sauna, Glenn's book is a practical guide designed to help take you from idea to finished hot room. It draws on years of hands-on sauna building experience and covers the key decisions that matter most—from layout and bench design to heaters, ventilation, materials, and the details that help create good heat.
