energy conservation theory of sleep author

How does caffeine make us feel more awake? The energy conservation theory suggests that the primary function of sleep is to reduce an individuals energy demand and expenditure during part of the day or night, especially at times when it is least efficient to search for food. One of the most important portions of the sleep cycle is called REM sleep. The electrophysiological and thermoregulatory continuum of slow wave sleep, circadian torpor and hibernation substantiates a primordial link between sleep and energy conservation. Some adults function fine on seven hours per night, while others need eight or nine hours of sleep. Before the 1950s, scientists believed that the brain would just shut off when we would go to sleep. Additionally, just one night of sleep deprivation can lead to decreased mental performance, though these effects improve after recovering lost sleep time. conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. The energy conservation theory suggests that the primary function of sleep is to reduce an individual's energy demand and expenditure during part of the day or night, especially at times when it is least efficient to search for food. Energy Conservation Theory - Sleep reduces an organism's energy needs at night when it's not efficient to search for food. Consistently exercising can improve sleep health by increasing sleep quality and reducing daytime sleepiness. 2.
