The Traditional Chinese medicine believes that, outward is the internal manifestation. Infrared image can reflect the state of cold and heat, yin and yang in all parts of human body. So it is called the CT of TCM. Pre-study found that patients with sleep disorders have different infrared image than normal changes. Polysomnography is currently recognized as the golden indicator of sleep research. Polysomnography can monitor the whole sleep process, and study the sleep structure by the related indexes, which is a basic technique for Sleep medical research and diagnosis of sleep disorders, and a standard method of evaluating sleep-related pathophysiology and sleep architecture.
