This internal clock oversees circadian rhythms, or bodily functions that fluctuate over each day, such as metabolism, body temperature, and hormone release. The EA model of sleep also proposes that total energy is conserved beyond what it attainable alone through quiet wakefulness (see Section 4, Phenotypes of Energy Allocation), but the EA model is based on a set of principles different from the energy conservation model originally advanced as a function of sleep (Berger and Phillips, 1993, Berger .
