Biological Rhythms (Subscribe)
Biological organisms are affected by, and subject to, a whole host of biological rhythms that are influenced or moderated by a variety of external and internal stimuli.
Classically, biological rhythms are affected by light. The well known mammals' circadian rhythm, the 24-hour biological timer that regulates numerous bodily functions is synchronized to light and dark by the light arriving at dawn. These rhythms affect everything from body temperature and blood pressure regulation to intellectual performance, sleep and wakefulness.
