I could feel the warmth from the infrared and I was lying for about 30 minutes when I felt a tug around my heart area and all this love starting coming out in that area across my chest. I could almost see the rays coming up through my body in 3 to 8 inches. I was so relaxed afterwards, and I never had an ache, pain or stiffness anywhere. The next day I went on it and after about ten minutes I just felt my system elevate - neat. I'm looking forward to getting this mat, as it will help my life a lot. I think it would be great for people who meditate as well as for healing. Thanks a lot!
