Endocrine regulation of circadian physiology

Circadian clocks regulate 24-hour rhythms of behavior and physiology, influenced by hormones.

• The endocrine system acts as a significant output of circadian clocks, affecting various biological processes.
• Rhythmic hormones can provide feedback to the circadian system, helping to maintain the stability of internal rhythms.
• Modern lifestyle factors, such as shiftwork and high-calorie diets, may disrupt the balance of clock-hormone interactions.
• Adrenal glucocorticoids and metabolic peptide hormones are highlighted as key elements in the communication between circadian timing and the endocrine system.
• Hormones may serve as systemic signals that adjust clock function, contributing to the maintenance of physiological and metabolic rhythms.
