There are five types of body rhythms such as diurnal, circadian, ultradian, infradian, and circannual rhythms. The present review aims to discuss body rhythms, body rhythms disorders, and their energetics. Diurnal rhythms occur during the day and in resting, or inactivity at night, circadian rhythms complete one cycle in 24 hours and known as midday activity, ultradian are recurrent or repeated cycle in 24 hours, infradian rhythms complete one cycle more than one day, and circannual rhythms complete their cycle in 24 hours or one year.
