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. 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 helps regulate your metabolism to control blood sugar levels. These phases develop continuously, from stage 1 to REM and then back to stage 1. Sleep could be best described as a __________.

The adaptive theory of sleep is one of the first sleep theories that suggested sleep as an adaptive behavior to protect against natural hazards and predators. During wakefulness, many biological processes occur, and the body becomes depleted of its stores. These animals did not have accidents during activities in the dark, for example, and were not killed by predators. Brain plasticity theory suggests an existing link between sleep and brain plasticity, wherein sleep enhances brain plasticity contributing to cognitive abilities and performance of tasks. Caffeine intake, however, can block adenosine activities in the brain, keeping us attentive. Lack of time or stressful living schedule may hinder there sleeping time. During sleep, the body has a chance to clear adenosine from the system, and, as a result, we feel more alert when we wake. During wakefulness, energy utilization is preferentially allocated to waking effort (WE): i.e., vigilance, foraging, and reproduction. The adaptive theory of sleep is one of the first sleep theories that suggested sleep as an adaptive behavior to protect against natural hazards and predators. The theory goes back more than 2,300 years ago, but has been popular because many genes have shown to . One of the proposed functions of sleep is to conserve energy (Berger & Phillips, 1995).Energy expenditure (EE) is hypothesized to be lower during sleep versus wakefulness to reduce total daily energy needs. Scientists believe that this accumulation of adenosine during waking hours promotes the urge to sleep, as adenosine builds up and remains high while we are awake. 1990;345:41-50; discussion 51-2. . Adults typically need seven or more hours of sleep per night, and younger adults generally sleep more than older adults. Energy Conservation Theory. Sleep is a state of altered consciousness, characterized by certain patterns of the brains activity and inactivity. We lie on our warm, cozy queen mattresses motionless for a few hours, while our head rests on the doughy white pillows, our muscles are paralyzed and our breathing is unconsciously monitored through our brain. As we sleep, fluid flow through the brain increases. A schematic of the sleep-wake cycling energy allocation model. Discoveries about sleep's link with changes in brain plasticity, which is the structure and organization of the brain, led to one of the most recent and intriguing theories as to why we sleep.

Relaxation techniques can also reduce stress, which is known for making it more difficult to fall and remain asleep. When this happens, the brain and body decrease responsiveness to external stimuli. These were restoration, energy conservation, and brain function. Scientists think that this build-up of adenosine during wakefulness may promote the "drive to sleep." Second, sleep helps memory consolidation, which is critical for successful learning. The first kind of energy to be recognized was kinetic energy, or energy of motion. A. generates new energy for daily activities B. can regenerate and heal injuries quickly C. allows organisms to consume fewer resources D. allows organisms to escape from danger. Research indicates that human metabolism slows significantly during sleep, suggesting we use this time to save energy for more active periods. Warmer temperatures increase overall alertness, keeping sleepers in a more wakeful state.
