Fibromyalgia is a common chronic disease, described by deep, persistent pain throughout the body, sleep troubles, and fatigue. At times, the pain can be so intense that some are unable to complete normal activities. A gentle treatment that is popular in Japan is called Ganban-yoku, a form of natural thermal therapy using mineral stones that release far-infrared rays. Deep and gentle heat helps to ease the pain without any side effects. It also increases the circulation of the internal organs. Reduced pain, toxins, and stress levels can lead to better and deeper sleep. When you are rested, you typically feel better overall.
