Unlike steam saunas, which envelop you in moist, humid air, dry saunas provide an environment of intense, radiant heat. The sauna's electric heater or wood-burning stove gradually elevates the temperature, allowing you to experience a deep, penetrating warmth that induces a therapeutic sweat.Low Humidity: Dry saunas maintain low humidity levels, usually below 20%. This results in a more intense, sweat-inducing experience.
