Acupressure techniques stimulate the body to release endorphins that cause a natural analgesic effect (pain relief). The Energy Mat is equipped with acupressure points. It may be nerve-racking at first, but once you stand with both your feet or lay your whole back on it, the pressure evens up. Continue standing or laying on the Energy Mat for 10-15 minutes and feel the difference. Once the body releases endorphins, you will feel relaxed, happy, and your pain subside. So relax longer on the Energy Mat for prolonged benefits. Users often lay on it before sleeping to improve their quality of sleep. 40cm x 40cm approx.
