Our internal circadian clock regulates daily life processes and is synchronized by external cues, the so-called Zeitgebers. The main cue is the light-dark cycle, whose strength is largely reduced in extreme habitats such ...

Circadian rhythms keep time for all living things, from regulating when plants open their flowers to foiling people when they try to beat jet lag. Day-night cycles are controlled through ancient biological mechanisms, evolutionarily ...
