It was based on the principle of Chinese traditional acupuncture with hundreds of acupressure nails. Each nail is made of hundreds of lotus spikes; so the whole mat has thousands of acupressure points. Naturally reduce muscle tension, back pain, and headaches by simply laying on the mat daily for 10-30 minutes. Acupressure releases endorphins that block pain, and helps relax the muscles in your back, neck and feet.
