Abstract

Circadian clock disruption is associated with decreased cognitive performance and increased risk of obesity, diabetes, and cancer.

  • Endogenous circadian clocks regulate 24-hour rhythms of behavior and physiology in most species.
  • Hormonal factors exhibit strong daily secretion patterns, influencing communication between the brain and body.
  • Different tissue oscillators contribute to the regulation of hormonal release and action.
  • Changes in circadian timing can affect hormone signaling and subsequent physiological processes.
  • Recent findings indicate that hormonal signals may influence circadian regulation, potentially disrupting metabolic balance.
