The gemstones are entirely crushed which removes the rigid quality found in a lot of our other models and forms a softer surface. The heat makes the gemstones release far infrared rays and negative ions to relieve chronic pains, restore energy, relax the mind and body, and so much more. There is no limit to what you can accomplish with consistent effort to improve your wellness each day. You can also use this mat alongside any other HealthyLine Mat to create a sandwich-like set-up. This will trap the heat and simulate a fully immersive sauna experience that helps with detoxification and cleansing. If you are looking for an unconventional, yet effective device this is a good place to start.
