Terahertz Carved Ring Terahertz ore is said to emit electromagnetic waves called "terahertz waves." Terahertz waves have the characteristics of both radio waves and light, and vibrate 1 trillion times per second. This wavelength is known to penetrate various substances such as wood and plastic, and when applied to the human body, it has been known to increase body temperature and improve and activate cell distortion. The history of this research is long, and studies conducted by NASA in the 1950s-1970s concluded that terahertz waves are beneficial to the human body. In addition, all substances in nature emit weak terahertz waves, and it is thought that they are deeply related to the properties of matter and life activities. Furthermore, research has shown that terahertz ore has a very high thermal conductivity. It is often said that "terahertz ore melts ice," but this is due to its property of easily transferring heat (high thermal conductivity).
