Episode notes
Circadian System Controls Many Body Functions
- The circadian system coordinates nearly all bodily functions via internal clocks across the body.
- A master pacemaker of ~20,000 neurons in the hypothalamus synchronises sleep, hunger, memory, and pain rhythms.
Many Cells Have Their Own Clocks
- Cells throughout the body host local biological clocks that govern metabolism, blood sugar, and DNA repair.
- These peripheral clocks extend circadian control beyond the brain into cellular processes vital for health.
Disrupted Rhythms Harm Multiple Systems
- Desynchronisation of circadian rhythms can impair cardiovascular, immune, and tissue repair systems.
- Chronic disruption raises risks for metabolic disease, cardiovascular issues, immune disorders, and some cancers.
