- 4. Sleep 101: The Circadian Rhythm 4 Circa – “about”, diem – “day” Circadian – a cycle the occurs within about a day or a 24 hour period Most systems in the human body follow a circadian rhythm. This rhythm can be affected by sleep deprivation Changes in this rhythm can affect an individual’s performance
