Abstract

Disruptions in sleep/wake and eating schedules may increase the risk of chronic diseases like cancer and cardiovascular disease.

  • The human circadian system includes a master clock in the hypothalamus and peripheral clocks in various organs.
  • Circadian rhythms influence key biological processes such as body temperature, hormone secretion, and immune functions.
  • Misalignment of daily activities with the biological clock can impair physiological and psychological health.
  • Understanding the regulation of sleep circadian rhythms could provide insights for behavioral interventions to reduce disease risk.
