Circadian rhythms are a series of endogenous autonomous oscillators that are generated by the molecular circadian clock which coordinates and synchronizes internal time with the external environment in a 24-h daily cycle (that can also be shorter or longer than 24 h).
Conclusions: The history of sleep and biological rhythms is the history of mankind and of the planet. Sleep (or sleep-like states), circadian (sleep-wake cycle), and other biological rhythms, have ancient phylogenetic roots, deeply permeating and orchestrating virtually all the ecosystems of the planet. Anthropogenic behaviors have been interfering with such biological events, undermining planetary health.
