What are circadian rhythms, and how do they affect the body?
“The term ‘circadian’ means ‘about a day.’ Circadian rhythms are rhythms that rise and fall during the course of the day in a regular pattern. There are hundreds of bodily functions that operate on these daily rhythms, including hormone production, body temperature, when we sleep and when we digest food. Many of those have the combined effect of impacting our alertness.
