I want to be honest about why I bought it, because it matters. I did not buy an infrared sauna to feel younger, or to chase some wellness trend my daughter keeps texting me about. I bought it for one reason: my lower back and my right knee had been arguing with me every morning since the surgery, and I was tired of losing.

I'm 68. I spent 40 years in construction, and my body kept the receipts. After the knee procedure last year, the surgeon told me recovery would be slow and that stiffness was 'part of the deal at your age.' That phrase stuck in my craw. Part of the deal. Like I was supposed to just accept waking up feeling like I'd been folded into a suitcase overnight.

I wasn't in pain, exactly. I was stuck. Stiff getting out of the chair. Stiff on the stairs. Foggy until about eleven in the morning, then dragging again by three. My wife noticed I'd stopped taking the dog on the long loop. That's the thing about getting older — it doesn't announce itself. It just quietly takes things off your plate.

The Skeptical Part

I am not an impulse buyer. I read everything. And when I started researching infrared saunas, most of what I found made me nervous. Fly-by-night brands with no phone number. Vague warranties that expired the moment something broke. Cabinets that looked like they were held together with hope and glue. I nearly gave up twice.

What turned me around was two things. First, Peak was US-owned with actual US-based support — I could call and a real person answered. Second, the warranty. A lifetime warranty tells you a company plans to still be here when you need them. Companies that cut corners don't make promises like that.

I ended up on the phone with Danielle, the general manager. I expected a sales pitch. Instead she asked about my knee. She asked how I slept. She walked me through the full-spectrum infrared and the medical-grade red light therapy like she genuinely wanted me to understand it, not just buy it. She mentioned it was HSA/FSA eligible through Truemed — about 30% back — which frankly is what got it past my wife. And there was 0% financing with 25% down, so I didn't have to write one uncomfortable check.

The First Session

The unit is real Canadian Hemlock — you can smell it before you even turn it on, this clean, warm wood smell. It shipped crated and free, and it was at my door in under a week, which honestly shocked me for something that size.

I climbed in that first evening with low expectations. I just wanted the ache in my back to ease up. The heat isn't the sharp, suffocating heat of the old gym steam room — it's a deep, patient warmth that seems to reach into the joint itself. I ran it off the app from my phone bench, felt a little silly about that, and then stopped feeling silly because it was genuinely easy. Twenty minutes. My shoulders dropped. The knot behind my knee let go.

That night, I slept for eight hours without waking up once to shuffle to the bathroom. I hadn't done that in years. I figured it was a fluke.

What Nobody Warned Me About

It wasn't a fluke.

I went in for my back. The back got better. But the thing that changed my life was waking up at 6 a.m. actually rested — and still feeling good at noon.

By the end of the first month, the joint stuff was noticeably better — looser mornings, less of that folded-suitcase feeling. Research on infrared sauna therapy suggests it may support circulation and recovery, and I'll leave the science to the scientists. All I know is what my own body reported.

But the sleep. Nobody warned me about the sleep. Somewhere in that third week, I realized I'd stopped lying awake at 2 a.m. staring at the ceiling. I was falling asleep like I did in my thirties. And the fog that used to sit on me until lunch? Gone. I'd be sharp by mid-morning, still had gas in the tank at three in the afternoon.

Here's what that actually looks like in a life:

• I take the dog on the long loop again. Both loops, some days.
• My wife and I do the crossword at breakfast because I'm awake enough to be good at it.
• I stopped napping in the recliner at four o'clock — the nap I swore was 'just resting my eyes.'

The Ritual

It's become the anchor of my evening. Twenty minutes in the warmth, the red light on, the day coming off my shoulders one degree at a time. It's the closest thing I have to a moving meditation, and I'm not a meditation guy.

I bought a box that heats up. What I got back was the version of myself that shows up rested, moves without wincing, and has something left over for the people he loves. If you'd told me the biggest change would be measured in sleep and not in my knee, I'd have laughed. I'm not laughing now. I'm just sleeping.
