"The far infrared is the only thing that took away the daily inflammation in my knee that made me limp by the end of the day. After two months, I felt improvement, and with daily use, I've experienced less stiffness, less puffiness, more energy, and even some weight loss."

My Symptoms Were Gone in Six Weeks

After using my infrared sauna every day for six weeks, I can honestly say my symptoms are gone. The stiffness and hives I was experiencing have completely disappeared, and even the pain from two shoulder surgeries is gone. I have more energy, I've lost weight, my skin looks better, and I feel healthier overall. This is one of the best gifts I've ever given myself.
