During which time in the horary cycle is the kidney most active?

In Traditional Chinese Medicine (TCM), the horary cycle refers to the 24-hour cycle in which each organ system exhibits peak activity at specific times. The kidneys are associated with water, storage, and reproduction, and their most active time is from 5 pm to 7 pm.

During this period, the body is thought to focus on storage and nourishing, relating to the function of the kidneys in managing the body's fluids, supporting adrenal function, and influencing overall vitality. This time is also significant for winding down, preparing for rest, which aligns with the kidneys' role in conserving energy and supporting restorative processes.

Understanding the timing of organ activities helps practitioners optimize treatments, tailor acupuncture sessions, and offer lifestyle advice that harmonizes with the body's natural rhythms.
