Cold Chamber & Metabolism
Cold is a powerful metabolic stimulus. Three minutes in the cold chamber at -110 °C force the body to produce heat – and that takes energy.
In the chamber, the skin's blood vessels constrict and the body holds warmth in its core. After stepping out, the vessels widen again, circulation runs at full speed and energy expenditure stays elevated for a while. Brown fat tissue is also activated – a tissue type that converts energy directly into heat instead of storing it.
A single session doesn't replace a calorie deficit or training. Anyone wanting to lose weight combines cold with exercise and an adjusted diet. The advantage of the cold lies in the interplay: more drive, better sleep, less muscle soreness – exactly the factors that make a change in diet sustainable.
For a noticeable metabolic impulse, 2 to 3 sessions a week over at least four to six weeks have proven effective. Anyone coming regularly gets the best value with the monthly unlimited pass (€349 per month, unlimited sessions); for getting started, the 5- or 10-session package is a better fit.
Reliable figures vary widely and depend on body composition and starting point. More important than the single session is the repeated stimulus over several weeks.
For weight loss, the session fits well after training or on training-free days. Right before a strength session it's less useful, because the muscles cool down.
