Cold plunging can look intimidating, especially when what you see online is someone reacting to freezing water or trying to stay in as long as possible. We understand why that gets attention, but it can leave out a lot of what the experience actually involves. At Ritual, we're bringing sauna and cold plunge together in a space where you can slow down and make time for recovery.
Contrast therapy involves moving between the sauna and cold plunge, with rest between rounds. You warm up in the sauna, spend a brief period in the cold, and pause before beginning another round. A session allows you to move through that process without feeling rushed.
For us, the practice is also about giving recovery a regular place in your week. Over time, you become familiar with the experience and how to make room for it alongside everything else you have going on. We want that routine to feel manageable, with time to rest and pay attention to how you feel each visit.
The most direct evidence we lean on is a study by Susanna Soberg and colleagues, published in Cell Reports Medicine in 2021. Soberg is a metabolism researcher in Copenhagen, and the tradition she studied is not really a cold tradition at all. It is a hot and cold one. The Scandinavian winter swimmers in her study did not just jump in the sea. They paired cold water with sauna, usually two to three times per week, and had done so for years. Compared with a control group, these men showed signs of adaptation to both heat and cold, including changes in brown fat activity and increased heat production during cold exposure. One important caveat: this was a small study of young, healthy men, so the results may not carry over to everyone. Soberg later walked through the work on the Huberman Lab podcast in 2023, which is a good listen if you want the longer version, but the study itself is the source worth knowing.
The idea worth taking from that research is about pattern, not heroics. The swimmers were not doing one dramatic session. They kept a rhythm, and the adaptations the researchers measured came with that rhythm. We are not going to promise that contrast therapy will change how you feel, and we will not pretend the science is settled, because it is not. What the research suggests so far is that pairing heat and cold, done consistently and kept brief, is where the measurable effects have shown up.
Here is the honest caveat about the cold itself. Short is the point. Soberg's often quoted suggestion is that a total of around eleven minutes of cold across a whole week, spread over a few short sessions, may be enough. That number comes from her study protocol and her own interpretation of it, not from a large trial, so treat it as a starting point rather than a rule. The heat can be longer and easier. The cold is meant to be brief and a little uncomfortable, and then you are out. Gritting your teeth for five straight minutes to feel tough is not the loop. It is just a longer dare.
So when someone asks us what contrast therapy is, the honest answer is not just a switch between hot and cold, it is a practice. Heat up, cool down, repeat, a couple of times a week, until it stops being a challenge and becomes a normal part of how you take care of yourself.
We're building Ritual Studio in University Place because we know from our own lives how hard it can be to make recovery a regular part of the week. Rory works for CrossFit, and I'm a firefighter and former professional water polo player. We have two young kids and jobs that take a lot out of us, so we wanted to create a place where people like us can set aside time, put their phones away, connect back with themselves, and have access to contrast therapy. We care about the space, how people are welcomed, and helping them feel comfortable with the practice so it becomes something they can realistically fit into their lives.
We are opening in early 2027. If you want to follow along as the space comes together, the Founding Member Waitlist is open now, and the first 75 members get Founding Member Pricing. Follow along as we get closer to opening.
