Radiant heat is healthy heat. Think of standing outside on a warm sunny day – remove the light from the sun and keep the heat. This is infrared heat. Infrared heat is the safest and most effective form of heating the body. Infrared heats objects, not the air, thus making it comfortable to practice yoga as well as increasing circulation and helping the body’s natural processes kick in to eliminate waste and build up of lactic acid and environmental toxins.
