Sauna has always been part of human wellbeing. What’s changing is how clearly we can track what happens when heat becomes a consistent ritual—measured, repeated, and built into real life.
This is the idea behind Sauna Habit: a January focus on turning new year intentions into an ongoing bathhouse ritual—heat, cold, rest, repeat—so you feel the difference that consistency creates.
It’s also why we’re sharing the latest sauna findings from Bryan Johnson (a well-known longevity experimenter), alongside the wider body of sauna research that has been building for decades.
What’s new right now: Bryan Johnson’s latest sauna findings
You might not know Bryan Johnson yet. He’s a tech founder turned longevity experimenter who runs structured personal experiments and publishes his results openly—testing before and after, then refining his protocol over time.
In his latest sauna update, Bryan reported three outcomes that stood out:
- Lower levels of several measured environmental chemicals after 15 sauna sessions (with some dropping to “undetectable” in follow-up testing).
- A reduction in measured microplastics over time.
- Improved blood vessel function and blood pressure measurements, which he described as a meaningful shift in cardiovascular health.
A grounded note: this is one person’s data, not a clinical trial. But it’s still valuable because it reflects a modern, measured look at what can shift when sauna becomes a repeatable practice.
His headline takeaway aligns with what many clinicians and researchers emphasise: sauna is most meaningful when it’s consistent—not a once-off experience you do “when you remember.”
What research has suggested about sauna benefits
Sauna research is extensive, especially from Northern Europe where sauna bathing is culturally common. While individual results will always vary, research has repeatedly explored sauna in relation to:
- Cardiovascular health (heart and blood vessel function), including associations with improved outcomes in long-term population studies.
- Circulation and blood pressure, because heat increases blood flow to the skin and creates a gentle cardiovascular “training” effect.
- Stress reduction and recovery, as heat + quiet + rest can support nervous system downshifting and a calmer baseline.
- Sleep quality for some people, particularly when sauna is earlier in the day or followed by a calming wind-down routine.
One important distinction: much of the best-known long-term population research reflects traditional Finnish-style sauna bathing—hotter temperatures and typically drier heat. That doesn’t mean other forms of heat are “worthless.” It simply means traditional sauna is where the research base is deepest.
Traditional sauna vs infrared sauna: how to choose (and why it’s not either/or)
At Nature’s Energy, we offer traditional and infrared saunas as part of your bathhouse circuit. They’re different experiences—and the best choice is the one you’ll return to consistently.
- Traditional sauna: classic heat experience, often higher air temperature, and for many people it delivers that deep, full-body “reset.”
- Infrared sauna: a gentler heat experience that many guests find easier to start with, especially if they’re new to sauna or prefer a softer entry point.
Our view is simple: build a ritual you’ll repeat. Consistency beats intensity.

The Sauna Habit protocol: Hot → cold → rest → repeat
We keep the bathhouse ritual simple and repeatable:
1) Hot
Choose your sauna (traditional or infrared). If you’re new, start gently—shorter sauna time, longer rest.
2) Cold
Cold immersion is powerful, but not compulsory. You can start with a cool rinse, or try the ice bath briefly if it feels right. Our Glebe and Newtown locations also include pail showers for a quick refresh.
3) Rest
Rest is where the system settles. It’s not an afterthought—it’s part of the method. Sit, breathe, hydrate, and let your body recalibrate.
4) Repeat
2-3 rounds are often plenty. Finish with the mineral pool and red light therapy if you’d like, then leave slowly—unrushed.
Tip: Hydration matters. Heat makes you sweat. Drink water before and after, and don't forget to try our Celtic hydration salts - complimentary for all bathhouse guests.
How often should you do it?
This is where Sauna Habit becomes real. The goal isn’t to do the “hardest” session. The goal is to build a rhythm you can sustain.
- If you’re new: start monthly, then fortnightly, then build toward a steady routine.
- If you already love sauna: weekly is where many people notice the biggest shift in how they feel day-to-day.
When guests tell us “I came once and loved it,” our response is simple: come back. The calm and clarity you feel after one visit is real—but the benefits of a ritual build when it becomes part of your life. Science has proven this.
