Discuss research into the disruption of biological rhythms.
Most human and non-human animal functions are cyclic, alternating over a period of time. Obvious examples include the sleep-wake cycle which repeats over a 24 hour cycle, or the hibernation patterns of some creatures that typically rest through the winter months and awaken in spring.
Menstruation in the human adult female is an example of an infradian biological rhythm. Circannual cycles last about a year; over-winter hibernation as a common example. The shortest cycles are ultradian, where the cycles are less than 24 hours. Heart rate and breathing are two examples of ultradian biological rhythms. Function.
Shift Work This can involve working times where people would normally be asleep, and being asleep at times when people are normally awake. This causes a breakdown in the usual coordination between internal biological clocks and external cues. This requires a drastic change to.

Biological rhythm, periodic biological fluctuation in an organism that corresponds to, and is in response to, periodic environmental change. Examples of such change include cyclical variations in the relative position of Earth to the Sun and to the Moon and in the immediate effects of such variations—e.g., day alternating with night, high tide alternating with low tide.
