The secrets of the body clock: how to tune into your natural rhythms

Our circadian cycle doesn’t just affect our sleeping and waking, but our motivations, mood, behaviour and alertness. Whether you are a lark or an owl, here’s how to recognise your own rhythm

The secrets of the body clock: how to tune into your natural rhythms

TL;DR

  • Our bodies have internal biological clocks that regulate daily cycles of sleep, hunger, mood, and energy.
  • These circadian rhythms are influenced by the light-dark cycle, which acts as a primary signal for synchronization.
  • Individual differences in internal clocks, known as chronotypes, result in variations like being an 'early bird' or a 'night owl'.
  • Artificial light at night can disrupt these rhythms, negatively affecting our biology.
  • Mitochondria, the energy producers in our cells, also have their own circadian rhythms, influenced by light.
  • Disrupting routines can lead to desynchronization, impairing the body's predictive abilities and metabolic efficiency.
  • Exposure to natural daytime light is considered important for maintaining healthy biological rhythms.
