Sunlighten mPulse Series is the world’s first and only Android-powered line of smart infrared saunas to offer 3-in-1® Full Spectrum technology. The infrared spectrum consists of near (NIR), mid (MIR), & far (FIR) waves, each with distinct characteristics & frequency ranges. NIR promotes skin renewal, cell health, wound healing, & tissue growth. MIR helps expand blood vessels & increases circulation. More oxygen reaches injured areas of the body, reduces pain & speeds the healing process. FIR reaches deepest into the body where toxins are stored. By raising core body temp, FIR stimulates the sweat glands, resulting in a detoxifying sweat. Sweating increases heart rate, cardiac output, & metabolic rate, so you’re also burning calories. There are 6 preset wellness programs at your finger tips to meet your individual goals. Constructed with PEFC Certified eco-friendly wood and anti-bacterial carbonized bamboo carbon heater covers.
