The Vital Dome® uses far infrared technology to uniformly raise the internal temperature of the body for a number of benefits such as detoxification, relaxation, pain relief, weight management, sleep induction and conditioning among the others. Far infrared rays are naturally present at sunrise and sunset and are perfectly compatible with the body when they penetrate deep into the tissues. They emit the ideal energy to stimulate at the cellular level and promote natural regenerative processes that are vital and beneficial to the body.
