Circadian rhythm: those that last around 24 hours the two main examples of circadian rhythms include the sleep- wake cycle and the body temperature cycle. Discuss research into biological rhythms (8+16) research into circadian rhythms has assessed the effects of isolating participants from their external time cues (exogenous zietgebers) on our 24 hour cycles, and suggesting that an internal body clock (endogenous pacemaker) creates a free-running cycle of 25 hours.
The biology of sleep circadian rhythms, sleep stages, and sleep architecture your body’s natural daily rhythms are regulated by structures in the brain that help determine when you fall asleep and wake up. Research into circadian rhythms has assessed the effects of isolating participants from external time cues (exogenous zeitgebers) on our 24 hour cycles, and suggesting that an internal body clock (endogenous pacemaker) creates a free running sleep/wake cycle rhythm of 25 hours for example siffre .
