Oregon Sauna & Cold Plunge Experiences

Across Oregon, sauna-and-plunge rituals are turning up the heat on connection, calm and date night

written by Cathy Carroll

Sitting naked in a rustic cedar sauna in the forest along the Breitenbush River, steam rising through slots in the wood floor and sweat beading down my back, I felt my core approaching the same temperature as the earth’s—unsurprising in a sauna perched atop a capped geyser of volcanically heated water from thousands of feet underground.

Pushing open the door, I plunged into a clawfoot tub of frigid water—a bracing slap that brought me to my heightened senses. I returned for sweatfest part two and emerged onto the snow-covered deck feeling triumphant, renewed, invincible. Giddy with geothermally induced vigor, I sat on a snow-covered ponderosa pine log, wearing two well-positioned fern fronds and posed for my Christmas card photo.

It was years ago, and recipients thought it proved the practice required a strong heart and a weak mind. Today, however, sauna-cold plunges pour into my Instagram feed, emblematic of a global trend that’s taking hold in Oregon in many forms. While I never forgot the rush of that experience at Breitenbush Hot Springs, I wasn’t rushing to try it again. I thought the new Flux Thermal Lounge in Bend would help. With six soaking pools ranging from 45 degrees to 104 degrees, it professes a no-pressure, good vibes reinvention of the lounge experience—part modern bathhouse, part social space. It hosts sound baths, DJ nights and “Ice Breaker,” a playful social evening designed around meeting new people in a relaxed, low-pressure environment. Queer community nights are in the works, too.

Flux founder and CEO Dini Vemuri said the concept is an alternative to Bend’s more traditional social infrastructure around alcohol consumption, offering warmth, cold, music, lighting and shared experience to create a different kind of social energy.

“There aren’t a lot of low-pressure ways to meet people,” she said. “If you go to the speed-dating things or you’re going on these apps, the vibe is just different versus here, where there’s no pressure, you can get into open conversation. There’s a whole bunch of other people, and it’s very approachable for introverts.”

It’s also popular for couples’ date nights—a distraction-free environment where phones are off-limits. “It’s a space where you can really settle into your own body, and when you feel settled, you’re much more receptive,” said Vemuri. “That high-bandwidth communication for any relationship is the basis for trust and respect that comes when you can really fully see each other, and this is a space where that can happen easily.”

Flux isn’t the only place reworking this ritual. A few miles away, at Gather Sauna House in Bend, Halina Kowalski-Thompson takes a route rooted in her own Baltic heritage. She spent fifteen years as a mental health counselor and trauma therapist at the Portland VA Medical Center, and now she applies that same lens to sauna and plunge—small, repeatable doses of stress that teach the nervous system it can recover. She trained with a master of Baltic sauna rituals, pirts (pronounced “peerts”), in Latvia.

That philosophy shapes how Gather runs: no clocks, no metrics. “This is one place not to be on a clock,” Kowalski-Thompson said. “We really want to encourage you to follow your body and listen to your body.” The signal to leave the sauna is simple: “When the idea of jumping in an ice-cold river sounds great.”

She points to its universality, from Finnish and Baltic to Roman and Indigenous sweat lodge rituals, nearly every culture developed some version of thermal cycling. Research supports the traditions: Heat triggers the production of proteins that help repair and clear out damaged cells, while cold exposure spikes dopamine and norepinephrine, resetting the nervous system and, over repeated sessions, training the body to handle stress more calmly, she said.

Kowalski-Thompson doesn’t prescribe minimums—even a few seconds in the cold does something good, she said, but for guests chasing real results, she points to a rough range of thirty seconds to four minutes per plunge, and a weekly baseline, drawn from recent research, of around fifty minutes total in the sauna and eleven minutes total in the cold, split across several sessions.

From October through May, Gather’s mobile, wood-fired sauna parks by the Deschutes River. When the river freezes, they simply break holes in the ice. The rest of the year, the sauna relocates to Hanai Foundation center in Bend, where coldplunge tubs stand in for the river.
