Question

Difference between circadian rhythms and ultradian rhythms and infradian rhythms

Answer 1

In chronobiology, an infradian rhythm is a rhythm with a period longer than the period of a circadian rhythm, i.e. with a frequency less than one cycle in 28 hours, such as menstruation, breeding, tidal or seasonal rhythms. In contrast, ultradian rhythms have periods shorter than the period of a circadian rhythm.

Answer 2

In chronobiology, an infradian rhythm is a rhythm with a period longer than the period of a circadian rhythm, i.e. with a frequency less than one cycle in 28 hours, such as menstruation, breeding, tidal or seasonal rhythms. In contrast, ultradian rhythms have periods shorter than the period of a circadian rhythm.
