Far infrared rays improve blood circulation, stimulate endorphins.

Far infrared rays improve blood circulation, stimulate endorphins, lower lactic acid, kill certain bacteria and parasites, and burn calories. Proponents of hyperthermia, also known as fever therapy, maintain that using far infrared energy to therapeutically induce higher body temperatures helps fight infections and even cancer. Their argument is supported by the human body itself, which radiates infrared energy for the benefits of warmth and tissue repair.
