Institute of Medicine (US) Committee on Sleep Medicine and Research. This internal clock oversees circadian rhythms, or bodily functions that fluctuate over each day, such as metabolism, body temperature, and hormone release. Unauthorized use of these marks is strictly prohibited. When the body sleeps it helps to grow muscle, repair tissue, and structure hormones. For example, research reveals that shift workers whose circadian rhythms become disturbed by working at night and sleeping during the day may be more likely to develop conditions such as depression, diabetes, and breast cancer. As a result, using devices at night may disrupt our ability to fall and remain asleep.

While melatonin dips early in the day and peaks at night, cortisol follows an opposite pattern. 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 .
