They've also examined the sleep habits of different organisms in prior research to see if there are any comparisons to be made between species that could indicate something on the role of sleep. Scientists have explored the question of why we sleep from many different angles. 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 . For example, while we are awake, neurons in the brain produce adenosine, a by-product of the cells' activities. 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. But in many cases, excess slumber is probably a side effect of other medical problems, rather than a cause. . Gender-Specific Association Between Sleep Duration and Body Mass Index in Rural China.

Stop procrastinating with our study reminders. What is the difference between the restorative and circadian theories of sleep? Sleep constitutes a circadian and circannual rhythm of hypometabolic adaptation to biospheric energy cycles that is usually entrained through light-mediated suppression of melatonin secretion. Institute of Medicine (US) Committee on Sleep Medicine and Research. FOIA During wakefulness, many biological processes occur, and the body becomes depleted of its stores. This internal clock oversees circadian rhythms, or bodily functions that fluctuate over each day, such as metabolism, body temperature, and hormone release. The evolutionary theory of sleep suggests sleep as ________ behavior to protect against natural hazards and predators. Sleep aids in relaxation and recovery from stress. Theory #2: Recovery and Restoration Sleep-mediated regulation of reward circuits: implications in substance use disorders. Over the course of a night, people cycle through three NREM phases and one REM sleep stage multiple times. conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. The sleep drive, a mechanism that promotes sleepiness and controls the intensity of sleep, also works with circadian rhythm to help regulate waking and sleeping patterns.

They have examined, for example, what happens when humans or other animals are deprived of sleep. Brain activity and eye movement increase. 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. Exactly how this happens and why our bodies are programmed for such a long period of slumber is still somewhat of a mystery.
