In the article about the Circadian rhythm, I have described an energetic clock that influences our functioning and sleep. Another energetic clock is the Chinese meridian clock. These are two different ways of looking at the same process: the parts of our body influence each other and play a role in our fitness.
The meridians, that the Chinese have distinguished for thousands of years, are a system, not actual lines running through the body.
Chinese healers use the meridians to identify weak spots in the body and to determine their acupuncture points. Sometimes the meridians are linked to organs like the heart, sometimes a meridian is linked to a concept like the Triple burner.
