Sauna Heat Acclimation
Sauna heat acclimation repeats moderate sauna sessions for one to two weeks to improve sweat response and heat tolerance. Hydration and gradual buildup are essential.
Sauna heat acclimation uses repeated passive heat—ten to twenty minutes at moderate temperature most days for one to two weeks—to improve sweat rate, plasma volume, and heat tolerance before summer sport or outdoor labor. Hydrate with electrolytes and avoid stacking sauna with dehydrated hard sessions.
