Infradian Rhythm

Meaning

An infradian rhythm refers to any biological cycle or oscillation that occurs over a period longer than 24 hours, distinguishing it from circadian rhythms which operate on an approximately 24-hour cycle. These longer cycles govern various physiological processes, often influencing hormonal fluctuations and metabolic states within the human body. The most commonly recognized infradian rhythm in humans is the menstrual cycle, spanning approximately 28 days.
