Why Contrast Therapy Works

Contrast therapy — alternating between heat and cold — isn't a new idea, but it's one backed by a growing body of research on recovery, mood and cardiovascular health.

Frequent sauna use, at 90°C for 10–15 minutes, is linked in observational studies to a 40% reduction in all-cause mortality when done 4–7 times a week. The heat pushes your heart rate up much like light cardio, supporting circulation over time.

Cold exposure works differently. A cold plunge can trigger a 250% increase in dopamine that lasts for hours afterward, which is part of why people describe the mental clarity after an ice bath as so distinct. It also appears to reduce inflammation.

Between the two, a 40°C magnesium-infused hydrotherapy soak gives your body a chance to actually absorb what an estimated 60% of adults are short on — magnesium — while 56 massage jets work on tension directly.

None of this requires a rigid protocol. At Sochill there's no instructor telling you when to move between stations — the flow is Finnish sauna, ice bath, dunk shower, hydrotherapy, in whatever order and for however long feels right. That's the point of not having a time limit.
