                            <p class="a-plus-plus">Circadian rhythmicity is of endogenous origin, that is, it is generated within every organism without needing the input of day-night stimuli. Its period is usually close to but not precisely 24 hr. In humans, the free-running period is typically about 25 hr. In fact, in most experiments all rhythms run in synchrony (“internally synchronized”). In a minority of experiments (i.e., 52 experiments to date), the period of about 25 hr is present only in some physiological rhythms (e.g., deep body temperature), whereas the sleep-wake rhythm and other rhythms run with considerably deviating periods (i.e., between 12 and 65 hr) and the rhythms are described as “internally desynchronized.”</p>
