Background reading
The biology of why cold exposure works — and the protocols that compound with the hardware.
Vagus nerve exercises — with whole-body immersion the main reaction is the sympathetic cold shock; the vagal (diving) response comes mainly from cold on the face, and HRV rises only during exposure (evidence)
Yes, especially in cold climates. Coldture is a Canadian-built premium tub with an integrated chiller, the strongest winter performance among consumer premium tubs, ozone sanitation and a 3-year warranty. Its protocol-guidance content is less developed, and US distribution is slower.
