Sunlighten mPulse Smart Sauna. Step into deeper relaxation and recovery with the Sunlighten mPulse Smart Sauna, one of the most advanced infrared saunas available. Powered by PulseIQ technology, the mPulse delivers near-, mid-, andfar-infrared wavelengths individually rather than blended together, so your body absorbs the right kind of heat for what you need. Choose from six science-backed wellness programs built around detoxification, immunity, weight loss, relaxation, heart health, and muscle recovery, and let Sunlighten's patented SoloCarbon heaters do the rest. The result is deep, absorbable heat that supports circulation and leaves you with a full-body sense of calm long after you step out.
