Core body temperature and sleep onset are more closely connected than most people realize. In the hours before sleep, the body begins to cool, and that cooling is a biological signal the brain is waiting for. A wood-fired sauna followed by cold immersion accelerates that process in ways that most sleep interventions do not reach.

This is the mechanism behind contrast therapy, and it is also why the setting matters. At Mist Thermal Sanctuary on Bowen Island, located next to its sister company Nectar Yoga Retreat, the sauna and cold plunge circuit sits within a coastal forest that begins its work on the nervous system by the time you reach the check-in, having walked up from the parking area through a winding set of steps along the forest trail. Thermal cycling and nature immersion in sequence produce an outcome that neither delivers on its own.
