Heat Acclimation Protocol
Gradual heat exposure over one to two weeks improves sweat response and endurance in hot conditions when hydrated safely.
A heat acclimation protocol gradually exposes you to hot training or sauna—lower heart rate at a given pace, higher sweat rate, and plasma volume expansion over seven to fourteen days in studies. Hydrate with electrolytes; build duration before intensity.
Not required for general fitness but helps hot-weather races.
