Chinese medicine’s 24-hour body clock is divided into 12 two-hour intervals of qi (vital force), which moves through the organ system. Chinese medicine practitioners use The Organ Body Clock to help determine the organ responsible for diseases. For example, if you find yourself waking between 3-5 a.m. every morning, you may have an underlying sadness or sadness that is bothering you or you may have a condition in the lung area. If feelings of anger or resentment do arise, you may feel them strongest during liver time which is 1-3 p.m. or perhaps if you experience back pain at the end of your work day. Can suppress feelings of fear, or maybe even kidney problems.
