Align Your Spine While Sleeping. The Crystal Rays Amethyst Pillow is for sleepers who want a more controlled sleep posture to address neck or back issues. This Pillow contains rows of amethyst stones sewn into the entire length of the pillow. These crystals reflect Far Infrared rays produced by the user. Powdered tourmaline and germanium ceramics amplify the Far Infrared Rays and produce greater amounts of Negative Ions. Professionals recommend Crystal Rays pillows over other pillows in its category. Crystal Rays pillows will not lose their firm support during sleeping. This pillow for your head should support the natural curve of your neck and be comfortable. When sleeping on your side, a firm pillow between your knees can reduce stress on your hips and lower back preventing lower back mis-alignment and pain. Crystal Rays mats and pillows should not be confused with other FIR products on the market. FIR is composed of various wave lengths. Long-wave FIR is used in space heaters to warm the people and objects in the room for energy efficiency. Short-wave FIR must be close to the object in order to penetrate and warm it. It is this short-wave FIR which Crystal Rays mats and pillows utilize. Additionally, the rare earth minerals in the Crystal Rays mats and pillows are used to change the frequency of the FIR into energy which can revitalize the body. The minerals in the Crystal Rays mats also produce very important negative ions. Negative ions have positive effects such as killing bacteria and cleaning the air. Plus, negative ions have been shown to promote positive brain health. This leads to the possibility of a more positive emotional state when a person is lying on the Crystal Rays pillow.
