Circadian Rhythm
A small cluster of cells in the brain runs a cycle of roughly twenty-four hours, and coordinates alertness, core temperature, hormone release, and when sleep becomes easy. Roughly is the important word: the cycle is not exactly twenty-four hours, so it has to be reset each day, mostly by light. This hub covers how that resetting works, why two people on the same schedule can be running on different clocks, and what a gap between your clock and your calendar looks like from the inside.

Guides in Circadian Rhythm
Nothing published in this hub yet
This hub exists before its first guide does — the topics are the structure of the site rather than a by-product of what happens to be written. Guides for it are drafted and will publish once they have cleared editorial review, under the team byline every page here carries. Nothing is being withheld from you; there is simply nothing yet that has cleared that bar.
