Circadian Rhythms

• Definition: Biological processes that display an endogenous, entrainable oscillation of about 24 hours.

• Characteristics:

  • Function independently of external cues but can be influenced by them.

  • Regulate sleep-wake cycles, hormone release, and other physiological processes.

• Common Examples:

  • Human sleep patterns

  • Hormonal fluctuations over the day

Key Concepts

• Endogenous: These rhythms are generated from within the organism, based on internal biological clocks.

• Entrainment: The process of syncing biological rhythms to external signals (like light and darkness).

• Influence of External Factors:

  • Light exposure can enhance or suppress the rhythmic cycles.

  • Variations in temperature and social interactions can also play roles.

Implications of Circadian Rhythms

• Health: Disruption can lead to various health issues, such as sleep disorders, obesity, and mood disorders.

• Adaptations: Understanding and regulating these rhythms can improve wellbeing and performance.
