The short answer
Choose by outcome, not by internet momentum.
Choose Sauna if people with safe sauna access who want a simple, repeatable heat routine.
Choose Cold exposure if experienced, healthy adults with a specific reason to use cold exposure.
They may be compatible, but more protocols do not automatically make a better plan. Add one at a time and keep the reason clear.
