IR Therapy is a hyperthermic therapy which uses infrared light to heat up the skin. Infrared light penetrates to a much deeper level, about 6cm, and heats up the skin from the inside, therefore the health benefits are substantial. At Peak we have invested in the Porsche among IR Therapies. While conventional IR saunas use only the far infrared (FIR), Sunlighten mPulse is the only IR Sauna offering a full spectrum IR light including far infrared, mid infrared and near infrared wave lengths for impact and results.
