Why it's here
Sodium
1,000 mg
The primary mineral lost in sauna sweat. Most post-sauna fatigue traces back to sodium deficit.
Potassium
400 mg
Replenishes cellular nerve and muscle function depleted by heavy sweating. 2× most electrolyte brands.
Magnesium glycinate
100 mg
Most bioavailable form. Calibrated below the daytime drowsiness threshold — works whether you sauna at 7am or 9pm.
Vitamin C
250 mg
Antioxidant support for the oxidative stress heat exposure creates. Most electrolyte brands skip this — we built around it.

What we left out — on purpose

No taurine
Recent research raised questions about taurine and certain cancer cell growth. We don't gamble on daily-use ingredients.
No creatine
Creatine works through saturation, not timing. Most of our customers take it separately. We don't double-dose.
No sugar
Zero added sugar. Lightly sweetened with organic stevia leaf extract and natural fruit tartness from vitamin C.
No artificial colors
No Red 40, no Blue 1, no dyes of any kind. Clean color from natural ingredients.
No proprietary blends
Every milligram of every ingredient is on the label. You should know exactly what you're getting.

FAQs

Why this much sodium?

A 30 minute sauna session can pull well over a liter of sweat, and sauna sweat is sodium heavy. Most electrolyte mixes are dosed for a light jog, not 175°F heat. 1,000mg of sodium replaces what the sauna actually takes out, which is why the post-session dizziness and headaches stop.

Do I drink it before or after the sauna?

Before. Mix one scoop in 16oz of cold water and drink it about 30 minutes before your session, so your electrolytes are topped up when the sweating starts. If you run long sessions, sip a second glass of plain water after.

What does it taste like?

Pink Lemon. Clean, lightly tart, lightly sweet from organic stevia. No syrupy sports-drink taste and no artificial aftertaste, because there is no sucralose and no dye in the tub.

Why not just add table salt to water?

Salt gives you sodium and nothing else. Sauna sweat also drains potassium and magnesium, which is what drives the cramping and the poor sleep. You would also be guessing the dose every time. This is the exact ratio, every scoop, plus 250mg of vitamin C for the oxidative load of heat exposure.

Is it safe with blood pressure medication?

Talk to your doctor first. Sodium intake matters if you are managing blood pressure, and your doctor should make that call. The upside of our label: every milligram is listed, no proprietary blends, so it is an easy conversation to have.

The Real Finnish Sauna Experience — Now Portable

For thousands of years, sauna culture has centered around one thing: real heat from real fire, radiating off real stones. The wave of löyly when water hits the rocks. The deep, full-body sweat that only happens above 170°F. The ritual of stepping out into the cold air afterward.

Most portable saunas can't deliver that. Infrared panels cap out around 140°F. Electric steam units can't produce löyly. Cheap tent saunas use underpowered stoves and thin materials that bleed heat in the first five minutes.

The KYFE Portable Sauna Tent is built differently. Triple-layer insulated walls. A stainless steel wood-burning stove that hits 200°F in under 30 minutes. Volcanic sauna stones and a rock cage for authentic steam on demand. Everything a traditional Finnish sauna gives you — in a kit that packs into a travel bag and sets up in five minutes.

Why Wood-Fired Matters

Temperature isn't just about comfort. The cardiovascular research most associated with sauna health benefits — improved heart function, heat shock protein activation, reduced inflammation, better sleep quality — is based on high-heat exposure above 170°F. Saunas that top out at 140°F or 150°F don't trigger the same physiological response, regardless of how they're marketed.

Wood fire also gives you something electric heat never can: no EMF, no wiring, no electrical dependency. Just fire, stone, steam, and air. The same elements people have been sweating in for millennia.

Real Heat. Real Steam. Real Löyly.

Löyly is the Finnish word for the wave of humid heat created when water is poured over hot sauna stones. It's the defining moment of an authentic sauna session — the thing that separates a real sauna from a warm room.

Every KYFE kit includes 35 pounds of consciously mined volcanic rock designed to absorb and radiate heat at high temperatures. Once your stove heats the rocks, you pour water, and the steam hits instantly. Add a few drops of eucalyptus or pine essential oil for aromatherapy depth. This is the experience Finnish sauna culture has been built around for centuries — and it's something no infrared panel or electric steam unit can replicate.

Built for Year-Round Use, Anywhere

Backyard. Cabin deck. Riverside campsite. Lake house. Snow-covered mountain retreat. The KYFE is designed to go wherever you go. The triple-layer insulated shell — 420D Oxford Polyester with PU waterproof coating, 120gsm cotton insulation, and high-temperature TPU windows — holds heat through cold weather and handles real outdoor conditions.

Pop-up fiberglass poles, stakes, and tie-downs mean setup takes minutes, not hours. And when you're done, the whole thing packs into a single travel bag.

Contrast Therapy, Completed

The most powerful recovery protocol in the world is thousands of years old: hot, then cold. Traditional Finnish and Russian banya cultures built entire rituals around it — sauna, then snow. Sauna, then river. Sauna, then ice bath.

Every KYFE Portable Sauna Tent ships with a free Kyfe Pod cold plunge, so you can run the full protocol from day one. Heat opens the vascular system, flushes metabolic waste, and triggers heat shock proteins. Cold snaps it shut, spikes norepinephrine, and activates brown fat. Done back-to-back, the effect compounds — deeper sleep, faster recovery, sharper mental clarity, and the kind of post-session euphoria the word kyfe was named for.

Who It's For

The KYFE Portable Sauna Tent is the right choice if you want authentic high-heat sauna performance without the cost or commitment of a permanent installation. If you have outdoor space — a backyard, cabin, campsite, or patio — and want everything included in one kit, this is built for you.

It's not the right choice if you need a strictly indoor solution with no outdoor access. For that, an infrared unit is a better fit.
