Clinical Chronobiology: Circadian Rhythms in Health and Disease.

Abstract in brief

• Circadian rhythms (CRs) are internal biological clocks that align with the 24-hour day-night cycle, primarily controlled by the brain's master clock in the SCN, which uses external cues like light to synchronize body functions.
• Disruptions in CRs can lead to sleep disorders and increase the risk of various health issues such as metabolic diseases, mood disorders, neurodegenerative conditions, and immune system problems, with treatments including light therapy, melatonin, and behavioral changes.
• The circadian system influences many bodily functions, including sleep, metabolism, and immune responses, and maintaining its proper alignment is crucial for overall health and managing certain conditions like epilepsy or mood disorders.]
