Circadian rhythms, or biological clocks, refer to daily cyclical variations or patterns of behavioral or physiological functions in animals and humans. Circadian rhythms are important in determining the sleeping and feeding patterns of all animals, including human beings. There are clear patterns of brain wave activity, hormone production, cell regeneration and other biological activities linked to this daily cycle. The rhythm is linked to the light-dark cycle.
