An early bedtime may reduce children's risk of obesity now and later in life. Proponents of the brain plasticity theory of sleep emphasize that sleep improves our brain plasticity. Proponents of energy conservation theory believe that sleep's primary job is to minimize an individual's energy requirements and expenditure during certain times of the day or night, particularly when searching for food is inefficient. When the body sleeps it helps to grow muscle, repair tissue, and structure hormones. Porkka-Heiskanen T. 1999.

When energy stores decline, energy is conserved by lowering Tb proportionally during sleep or by increasing the daily duration of sleep. The restorative theory, according to the Division of Sleep Medicine at Harvard, is the body's way of refreshing itself after a long day. Evidence contradicting a primary energy conservation function for sleep is that energy expenditure is only 10-15% less than that associated with quiet wakefulness [27], SWS increases during prolonged bed-rest [28] but decreases with restriction of energy intake and weight loss [29]. Sleep loss disrupts mental functioning and performance, making it more difficult to remain alert, learn new information, and process memories. Nerve cells create adenosine as a byproduct of their actions while we are awake. As the sleep cycles continue, the proportion of REM sleep in each cycle decreases. Babies, children, and teenagers all need more sleep than adults, but require less sleep as they age. Sleep disorders such as sleep apnea, for instance, can disrupt sleep cycles and leave people drowsy after a full night of sleep. Infants sleep for roughly 13 to 14 hours each day, with around half spent in REM sleep when most dreams happen. 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 . A link between sleep and brain plasticity is becoming clear in adults as well. Brain activity and eye movement increase.

The evolutionary history of sleep suggests why we need it. Along with serious negative health outcomes, a lack of sleep can affect day-to-day life. For example, while we are awake, neurons in the brain produce adenosine, a by-product of the cells' activities. Brain plasticity theory is that sleep is necessary for neural reorganization and growth of the brains structure and function. Growing evidence suggests that better sleep quality aids newborn brain development, and sleep disturbances negatively affect infant growth and overall health. This processing of light and darkness signals to the brain whether it is daytime or nighttime, informing the body if it should be awake or asleep. The body tries to heal itself through muscle and tissue repair, protein synthesis, and hormone production necessary for growth, all of which occur largely during sleep.
