According to traditional Chinese medicine, chronic sleep disorders are usually caused by a Yong-Yang imbalance resulting from energy disruption in your body. This energy is called Qi and is believed to be everywhere on Earth.
When you are in good health, Qi normally flows into the body, but if you are in trouble, the paths through which it passes are blocked, causing nighttime sleepiness.

But first of all, what is the Chinese time?
According to the Chinese clock of body organs, Qi is circulating in 12 major meridians associated with a relevant body. This cycle virtually lasts 24 hours and each of the tryupi systems has 2 hours to supply m, and Qi. When something goes wrong with you, energy is unable to penetrate signals sent to the brain that push you to wake up. Below you have several hours related directly to the organs.
