Ionic foot detox works by pulling the toxins out of your body through your feet. Potential toxins can range from impurities in the air, to chemicals in your home and beauty products. This process gives hydrogen in the water a positive charge. The positive charge attracts the negatively charged toxins in your body. The ions in the foot bath water hold a charge that enables them bind to any heavy metals and toxins in your body, similar to how a magnet works. This allows the toxins to be pulled out through the bottoms of your feet. The sessions are recommended as a series of ten at 30 minutes per session.
