Mysterious Sheet (Mini) This Mysterious Sheet is also known as a Hormesis Sheet. It is made by mixing a special mineral powder that emits weak radiation into medical-grade silicone. Hormesis is a phenomenon where a substance that is harmful when used in high concentrations or large amounts has the opposite effect and is beneficial when used in low concentrations or trace amounts. It is said that the hormesis effect is achieved by blending special minerals into the silicone. The minerals are mined from a gold mine located on the border of Hyogo and Okayama prefectures. How to use it: Place it under your pillow for a deeper sleep, or apply it to painful areas to reduce pain. It also speeds up the healing of fractures and wounds. Many people take it to rock baths and place it on the floor. In addition, placing it under devices such as computers reduces harmful electromagnetic waves. Free electrons (negative ions) are generated within a 30 cm square area around this Mysterious Sheet, and placing it under your pillow allows you to absorb negative ions while you sleep. This is probably the source of the restful sleep waves.
