    Infradian and Ultradian Biological Rhythms
    Hey, quick question...

    My teacher has described the infradian rhythm as LESS than once a day, and Ultradian rhythms as MORE than once a day.

    Is this correct? Defining these seems to be harder than it should be after searching on the internet.

    Thanks
    Luke

    This is what I've been taught:
    Ultradian rhythms = roughly 90 minutes
    Infradian rhythms = (eg. monthly and seasonal cycles)
