Track your heat.
Time your sauna.
Know your cold.
Yutori pairs sauna and cold plunge hardware with sensors and an app that tells you exactly what happened — and when to go again. No guesswork. No manual logging.
Sauna
Precision-built heat chambers with embedded sensors that track temperature curves, session duration, and your physiological response.
Cold Plunge
Chiller-powered plunge tubs that hold exact temperatures and sync with the app — so every cold exposure is recorded and repeatable.
The Yutori App
Your sessions,
visualized.
See your temperature curve, HRV response, and streak — all synced automatically from the sensor. No manual logging. No estimating.
- Live session temperature graph
- Cold exposure depth and duration
- Streak tracking and session history
- Safety alerts and exit guidance
Why thermal therapy
8 proven benefits
Decades of peer-reviewed research back the effects of heat and cold on the human body.
Heat stimulates HSP70 proteins that accelerate muscle repair between sessions.
Post-sauna temperature drop primes your body for deep slow-wave sleep.
Cold exposure spikes norepinephrine — the focus and mood neurotransmitter.
Regular heat sessions lower resting heart rate and improve arterial function.
Brown adipose activation from cold exposure increases caloric burn at rest.
Hyperthermia stimulates white blood cell production and immune response.
Contrast therapy cycles reduce systemic inflammation markers (IL-6, CRP).
Heat shock proteins and cold adaptation are linked to healthspan markers.
