Over 10 million students from across the world are already learning smarter. It is clear that sleep plays a role in the development of the brain in infants and children and explains why infants must sleep upwards of 14 hours per day. About the author. The energy conservation theory is also reinforced by the fact that smaller species have faster metabolisms, which means they consume more energy and make their bodies heat, requiring them to sleep for more extended periods. In order to really understand this worldwide commonality, you need to know some background on sleep, the stages in the cycle, and some common disorders (Central Idea). Research indicates that human metabolism slows significantly during sleep, suggesting we use this time to save energy for more active periods. This internal clock oversees circadian rhythms, or bodily functions that fluctuate over each day, such as metabolism, body temperature, and hormone release. Introduction: Im sure everyone likes sleep. Sleep is a vital element of health, and being even slightly sleep-deprived can negatively affect mental and physical well-being. Brain Plasticity Theory. Conversely, exposing eyes to light blocks melatonin production, making a person feel more awake. Author Information. Sleep may have some ability to help the brain rewire itself. Although it may be less apparent to people living in societies in which food sources are plentiful, one of the strongest factors in natural selection is competition for and effective utilization of energy resources. During sleep, we become unconscious while many cognitive and physical functions remain active. The quantity and quality of sleep have a major impact on learning and memory. government site.
