Infradian Rhythm

Infradian rhythms are biological cycles that last longer than 24 hours, typically happening on a weekly, monthly, or seasonal basis. Unlike daily rhythms such as the sleep-wake cycle, infradian rhythms regulate processes like the menstrual cycle, seasonal mood changes, or hibernation in animals. These rhythms are driven by internal biological clocks and can be influenced by environmental factors like daylight and temperature. Understanding infradian rhythms helps explain how our bodies naturally adapt to longer-term patterns in the environment, maintaining overall health and well-being.
