Traditional saunas heat the air around you to 180-200F using a stove and rocks. The experience is intense, and sessions are typically shorter.
Far infrared saunas use infrared panels to heat your body directly rather than warming the air. They operate at a comfortable 120-140F, allowing for longer, more relaxing sessions that penetrate deeper into muscle tissue.
For home use, infrared is almost always the better choice: lower energy costs, faster heat-up time, and a more comfortable experience. All Elite saunas use far infrared technology.
