Heat & cold
A guide to the ritual
How infrared warmth and cold immersion fit into everyday life — explained simply and honestly.
Ember · Heat
Infrared sauna
- Infrared saunas use infrared heaters to warm the body directly, typically at lower air temperatures than a traditional sauna — many people find this gentler and more comfortable.
- Many users describe sessions as a quiet time to relax, unwind after exercise or a long day, and step away from screens.
- Sessions are commonly between 15 and 40 minutes. Start shorter, stay hydrated and follow the manufacturer’s guidance.
Frost · Cold
Cold plunge
- Cold immersion means briefly submerging the body in cold water — a practice found in many cultures, from Nordic winter swimming to post-sport ice baths.
- People often say a plunge leaves them feeling alert, refreshed and focused.
- Begin with cooler rather than icy water and short durations, breathe calmly, and never plunge alone if you are new to it.
Contrast: moving between the two
Alternating heat and cold — often called contrast therapy — is a long-standing spa tradition. A typical rhythm is a warm sauna session followed by a short cool plunge, repeated a few times, finishing with rest.
