Over six months in 2024, I tracked down and interviewed fifty people who had purchased an infrared sauna within the past two years. Some owned saunas from Peak. Others owned saunas from Clearlight, Sunlighten, and a handful of direct-from-manufacturer brands you've probably never heard of. A few owned traditional Finnish saunas. All of them had strong opinions. And almost all of them — regardless of brand, regardless of price paid — shared three very specific regrets.
This is not a sponsored piece. I did not set out to sell you a Peak Sauna. I set out to understand what actually happens after someone buys one. The gap between the purchase and the results turns out to be far wider, far more complicated, and far more expensive than any brand's marketing would have you believe. The three regrets I found are real, they are common, and if you're in the market right now, every single one of them is completely avoidable.
What follows is a synthesis of those fifty conversations — the specific moments of frustration, the things people wish someone had told them, and, ultimately, what separates the owners who genuinely transformed their health from the ones who have a very expensive piece of furniture collecting dust in their spare bedroom. Read it carefully. There is a pattern here, and once you see it, you cannot unsee it.

Before We Get to the Regrets: Why Sauna Use Actually Matters
Most people who buy an infrared sauna are chasing a feeling. They read something, heard something from a friend, or watched a podcast clip where someone talked about using the sauna every day and feeling completely transformed. And here's the thing: the science behind that feeling is real. Genuinely, rigorously, undeniably real. The problem isn't that sauna doesn't work. The problem — and this is the central thread running through all fifty of my interviews — is that most people never give it a long enough, consistent enough chance to actually work.
Let me show you what's at stake, because the research here is not a collection of small wellness studies. This is some of the most compelling long-term physiological data produced in the last three decades.
Landmark Study: University of Eastern Finland
Between 1984 and 2011, researchers at the University of Eastern Finland followed 2,315 middle-aged Finnish men for an average of twenty years. The lead investigator, Dr. Jari Laukkanen, published findings that stopped the cardiovascular medicine community in its tracks. Men who used a sauna four to seven times per week showed a 63% reduction in fatal cardiovascular events compared to men who used it once a week. The same cohort showed a 65% reduction in Alzheimer's disease risk. Not a marginal improvement. Not a trend. Sixty-three percent. Sixty-five percent. Over two decades of tracking.
These were not elite athletes. These were ordinary men living ordinary lives — the only variable being how often they sat in a hot room. The dose-response relationship was clear and linear: more frequent use, better outcomes. Sauna use was as protective as regular moderate exercise for cardiovascular mortality in this cohort.
Separate research published in JAMA Internal Medicine and the European Journal of Preventive Cardiology has confirmed similar findings: regular sauna use reduces hypertension risk, improves arterial compliance, lowers systemic inflammation markers (including CRP and IL-6), and stimulates autonomic nervous system recovery that mirrors the benefits of aerobic exercise at moderate intensity.
What makes infrared sauna particularly compelling — and this matters when you're thinking about what type of sauna to buy — is the mechanism by which it creates these effects. Traditional Finnish saunas work by heating the ambient air to extreme temperatures (often 180–200°F), which then heats the body from the outside in. Infrared sauna works differently: the infrared wavelengths penetrate tissue directly, heating the body from the inside out at lower ambient temperatures (typically 130–150°F) that are far more comfortable to sustain for longer sessions.
But not all infrared is the same, and this is where most of the regret in my interviews began. Infrared light exists on a spectrum — near, mid, and far — and each range interacts with the body differently.
Far infrared alone — which is what most budget and mid-range saunas offer — gives you detox and heat. Add near and mid, and you add tissue healing, cardiovascular training, and cellular regeneration. The full spectrum is the full picture. But even that isn't the complete story in 2024, because there is a fourth modality that has accumulated its own staggering research base: red light therapy (photobiomodulation).
Red and near-infrared light in the 630–1060nm wavelength range — delivered at therapeutic irradiance levels — has been studied extensively for its effects on mitochondrial ATP production, inflammation reduction, collagen synthesis, hormonal regulation, and neurological function. A meta-analysis of over 400 trials published in the Journal of Photochemistry and Photobiology found consistent positive effects on pain, wound healing, and cognitive function. The challenge with red light therapy historically has been that you need a high-output, properly sized panel to get therapeutic doses to the entire body — not just to one spot at a time.
This is why the setup matters enormously. Most of the people I interviewed who reported the best outcomes weren't just using any infrared sauna. They were using full-spectrum infrared combined with dedicated, high-output red light therapy — simultaneously, in a single session. The combination effect is additive: the infrared creates vasodilation and increased circulation, which improves the delivery of photobiomodulation effects. And the red light extends the recovery and repair benefits beyond what heat alone can produce.
Understanding this biology is critical context for the three regrets. Because every single one of them traces back, in some way, to either not using the sauna enough, not using the right type of sauna, or not having any structured system to stay consistent once the novelty wore off.
The People Who Bought Sooner Wish They'd Done It Even Sooner
The first regret I heard in almost every conversation was the same: "I wish I'd done this years ago." Not weeks. Not months. Years. Across all fifty interviews, the average time between "I first seriously thought about buying a sauna" and "I actually bought one" was fourteen months. Fourteen months of deliberating, comparing specs, waiting for the right deal, or simply telling themselves it was too much money. And in almost every case, the person on the other end of that call told me something to the effect of: "I'm now convinced those fourteen months cost me real health outcomes."
The Cardiologist's Patient Who Stopped Going to the Cardiologist
Marcus had been managing borderline hypertension and elevated cholesterol since his late forties. He'd read the Laukkanen cardiovascular study in 2021 and been "pretty convinced" since then that regular sauna use was something he needed to take seriously. He spent two years going back and forth — reading reviews, watching YouTube comparisons, downloading spec sheets, asking questions in wellness forums. He finally bought a Peak Saunas Rainier in early 2023.
"Within three months of using it four or five times a week, my blood pressure had dropped meaningfully. My resting heart rate went from 74 to 62. My doctor asked me what I'd changed. When I told him I'd been using a sauna consistently, he said he'd been seeing this in the literature but hadn't had a patient actually do it. I felt genuinely good for the first time in years — like my body was working again instead of fighting against me." Marcus paused in the interview. "The regret," he said, "is two years. I had this thing working for me for eight months, and I spent twenty-four months talking myself out of it. That's twenty-four months of outcomes I didn't get."
"I'm a 54-year-old with a cardiovascular history. Within 90 days of consistent use — four or five times a week with the Peak Wellness Club sessions — my blood pressure, resting heart rate, and sleep quality all shifted measurably. My cardiologist is impressed. My only regret is that I deliberated for two years before pulling the trigger. Every month I waited was a month I didn't get back."
The Coat-Rack Problem: When a $7,000 Sauna Becomes a Very Expensive Room Decoration
Sandra is a 47-year-old physical therapist from Portland. She bought a competitor's full-spectrum sauna in 2022 — she spent $8,400, chose it specifically because it had both far and near infrared, and she genuinely believed in the science. For the first two weeks, she used it every day. Then work got busy. Then a vacation. Then the routine broke, and it never quite came back. Six months after buying, she was using it maybe once every two or three weeks. "I knew it worked," she told me. "I'd felt the difference when I was consistent. The problem was I had zero structure. Nobody had told me what to do. There was no protocol. I just sat in there and hoped for the best, and once the novelty wore off, 'hoping for the best' wasn't enough motivation to carve out 45 minutes."
Sandra eventually sold that sauna and purchased a Peak Saunas Shasta in late 2023. The deciding factor — the thing that made her willing to spend money on another sauna after the first experience — was the Peak Wellness Club. "When I found out there was an actual guided protocol system, where someone tells you what to do in the sauna to achieve specific goals — sleep, recovery, cardiovascular, skin — I was in immediately. That's what I was missing. I didn't need a better sauna. I needed someone to tell me how to use it." At the time of our interview, Sandra had used her Shasta 4–5 times per week for seven consecutive months without missing a week.
"I owned a competitor's sauna for 14 months and barely used it after the first month. The hardware was fine. The problem was I had no system, no accountability, no protocol. I switched to Peak because of the Wellness Club, and that changed everything. I've been 4–5 sessions a week for seven months straight. The sleep improvement alone was worth every penny."
Eight Thousand Dollars and a Diffuse Light Panel That Barely Registers on a Meter
Of the fifty people I interviewed, eleven had switched brands — meaning they had bought a sauna from one company, been dissatisfied with the red light therapy component specifically, and either sold it or supplemented with a standalone RLT panel. The most common scenario: they purchased a premium sauna from a well-known competitor that advertised "integrated red light therapy," only to discover that "integrated" meant diffuse LEDs built into the heater housings — not a dedicated, high-irradiance medical-grade panel. The difference in therapeutic output is substantial. One owner, Derek, a 41-year-old biohacker from Austin, put it bluntly.
"I paid $9,200 for a competitor's sauna with what they called red light therapy. I own a professional-grade irradiance meter. I measured the output at my seated position. It was registering around 12 mW/cm². The research threshold for meaningful photobiomodulation starts at roughly 20 mW/cm², and most of the strongest studies use 50–100 mW/cm² or higher. I was getting decorative light. Not therapeutic light." Derek spent an additional $1,400 on a standalone red light therapy panel. When he eventually upgraded to a Peak Saunas Fuji for his partner, he tested the built-in panel on day one. "At 6 inches I got 175 mW/cm². At 24 inches — the approximate distance in the seated position — I was still above 80 mW/cm². That's therapeutic. What I had before was theater."
"I own an irradiance meter. My previous sauna's 'integrated' red light therapy measured around 12 mW/cm² at seated distance — below therapeutic threshold. Peak's panel measures 80+ mW/cm² at 24 inches. I'd already spent $9,200 plus $1,400 for a standalone panel before finding Peak. If I'd just bought the Fuji first, I'd have saved $3,000 and two years of frustration."
The $7,000 Coat Rack: Why Consistency Is the Only Variable That Matters
Here is the most important thing I learned from fifty interviews: hardware is not the constraint. Most infrared saunas on the market — including perfectly decent sub-$5,000 options — are capable of producing meaningful health outcomes if used consistently. The constraint, in almost every case where someone wasn't getting results, was frequency. Specifically: the slow collapse from daily use to weekly use to monthly use to the sauna gathering dust while the owner feels vaguely guilty every time they walk past it.
The Laukkanen data is unambiguous on this point: you need four or more sessions per week to access the cardiovascular and cognitive mortality benefits. Not four sessions ever. Not four sessions per month. Four or more per week, sustained over years. That requires a level of behavioral consistency that the sauna industry — almost universally — does absolutely nothing to support. You buy the box, the box arrives, you get a paper manual, and you're on your own. No protocol. No goals. No accountability. No guidance on session length, temperature, or what to actually focus on while you're in there.
"Every single brand tells you what the sauna does. Not one of them — except Peak — tells you what to do once you're sitting inside it."
Sandra M., Portland OR · Former competitor brand owner, now Peak Saunas Shasta ownerThe data from Peak's own user base makes this contrast impossible to ignore. Owners who use the Peak Wellness Club — a structured guided-session system that travels with your sauna — average 4.2 sessions per week. Owners who don't? They average 1.8 sessions per week. That isn't a marginal difference. It is a 2.3x multiplier on the thing that actually drives outcomes — frequency. The difference between 1.8 and 4.2 sessions per week, projected over twelve months, is the difference between 93 sessions and 218 sessions. That is the difference between a sauna that changed your life and a coat rack with a digital display.
What the Peak Wellness Club actually provides: structured session protocols organized by health goal (sleep optimization, cardiovascular conditioning, athletic recovery, skin and anti-aging, stress and cortisol reduction, metabolic support). Each protocol tells you the specific temperature to target, how long to stay at each phase, whether to use infrared only or combine with red light therapy, and what to focus on cognitively during the session. The sessions are designed by wellness practitioners and updated regularly based on emerging research. The result isn't just that people use the sauna more — it's that they feel the results faster, which makes them want to use it more, which creates the compounding behavioral loop that the Laukkanen data requires.
Every Peak Sauna comes with a 60-day free trial of the Peak Wellness Club. After the trial period, membership is $49/month and can be cancelled any time. But here's what the data shows: the vast majority of members don't cancel. Once you've experienced the difference between sitting aimlessly in a hot box and following a protocol designed to produce a specific physiological outcome, sitting aimlessly doesn't feel like an option anymore. Over 10,000 active Peak Wellness Club members as of this writing. Average tenure: over eight months. These are not people who are staying out of inertia. They're staying because it works.
