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 drive on these daily rhythms, including hormone production and body temperature, when we sleep and when we digest food. Many of those combined effect our alertness. Circadian rhythms are programmed into the human body, causing us to be most alert during the day and to want to be asleep at night. They are the result of millions of years of evolution. They can't be reprogrammed. You can temporarily modify them by taking certain steps, but as soon as you stop taking those steps, you revert back to your natural state.
