Thank you for viewing! This is a terahertz bangle ( * ꒳ * ) If you are interested in terahertz, please take a look! Inner diameter approximately 16cm ★ Terahertz vibrates 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 improve body temperature and activate cells by correcting distortions. Terahertz waves are electromagnetic waves located between far infrared and submillimeter waves. They are thought to resonate with the vibrations of cells in the body, activating cells and promoting metabolism. While improvements in coldness and swelling due to improved blood circulation, improved skin luster and firmness, fatigue recovery, and improved immunity are expected, medical applications are also being researched, but there are individual differences in the proven health effects.
