This multi-functional far infrared sauna heating blanket is designed for burning fat, accelerate metabolism, promote systemic blood circulation, and more. The far-infrared heat diffuses deep into human cells and helps burn fat as the temperature rises. It's simple to use—Open it like a sleeping bag, put it in, and choose your favorite position. It has a flexible pulling capacity and heating wire designed to withstand stretching. It's guaranteed safe too! When the blanket is heated to 85 degrees, the treatment blanket will automatically disconnect the line, stop heating, and give an alarm for one minute. This blanket is suitable for home, beauty salon, spa, and home use.
