During which period is the pericardium most active?

The pericardium is generally considered to be most active between 9 PM and 11 PM. This timeframe aligns with Traditional Chinese Medicine (TCM) principles, specifically the concept of the organ clock, which delineates specific two-hour intervals during which each organ system is most energetically active.

During the period of 9 PM to 11 PM, the body is transitioning into a more restful state, preparing for sleep, and this is when the pericardium is believed to play a crucial role in protecting the heart from excessive emotional distress and in regulating emotional balance. The healthy function of the pericardium during this time is vital for emotional and psychological well-being.

In contrast, the other time periods listed are linked to different organ systems in the TCM organ clock: 11 PM to 1 AM relates to the gallbladder, 1 PM to 3 PM corresponds to the heart, and 7 PM to 9 PM is associated with the stomach. Each organ has its own peak activity time, so selecting the specific period of 9 PM to 11 PM accurately reflects the pericardium's highest level of influence and involvement in bodily functions according to TCM theory.
