Doing cardio before entering a sauna helps maintain an elevated heart rate, enhancing cardiovascular benefits. Aerobic exercise increases blood flow, raises core temperature, and activates the sympathetic nervous system. Entering a sauna immediately afterward prolongs this heightened physiological state, promoting continued circulation, improved oxygen delivery, and enhanced detoxification through sweating. This sequence may amplify metabolic effects, support cardiovascular conditioning, and increase overall caloric burn compared to sauna use alone. @_tylerfish
