Environmental Time Cueing

Meaning

Environmental Time Cueing refers to the process by which external, non-photic and photic stimuli, known as zeitgebers, synchronize the body’s endogenous circadian rhythm with the actual 24-hour cycle of the external world. These powerful environmental signals serve as temporal anchors for the central pacemaker in the brain, ensuring that physiological processes are optimally timed for day and night. Maintaining consistent exposure to these cues is vital for robust hormonal and metabolic health.
