Rather, sleep duration across species is associated with their ecological niche and feeding requirements, indicating a role for wake-sleep balance in food acquisition and energy conservation. It is generally believed by researchers that sleep evolved as a way to conserve and restore energy. This has been noted even in some insects (such as the fruit fly described above) and is easily observed in humans with the use of polysomnography. Prospective epidemiological studies in industrial societies indicate that 7 h of sleep per night in people aged 18 years or older is optimum, with higher and lower amounts of sleep predicting a shorter lifespan. During this time, a person can be easily awoken and may remember dreaming. This review will discuss the evolutionary forces that may be responsible for phylogenetic differences in sleep and the potential core functions that sleep fulfills. 2005 Oct 27;437(7063):1264-71. doi: 10.1038/nature04285. any sleep function will involve specific gene expression and macromolecular biosynthesis, and as we explain there may be important connections between brain energy metabolism and the need to remove metabolic wastes.a deeper understanding of sleep functions in endotherms will enable us to answer whether or not rest behaviors in species other than Accessibility Of course, animals and humans are able to sleep briefly and maintain wakefulness over long periods of time when necessary, but this does not lead to optimal functioning. Brain plasticity theory is that sleep is necessary for neural reorganization and growth of the brain's structure and function. Dreams: The biology of sleep and dreaming. The field of evolutionary psychology tries to explain this phenomenon. It describes the current concept of sleep and its functions, based on research on the mammalian system. Humans evolved from a common ancestor with other apes, so to understand how human sleep occurs, we look to the sleep patterns of other apes. While his theories were later subverted and used to promote racism, like President Lincoln and the NAACP, Darwin helped us to recognize the equality of all human beings. Over the course of a good night's sleep, our brains cycle between these stages, and certain brain activities occur during each one. December 1, 2017. One evolutionary theory of sleep holds that sleep is essential for restoration of resources that are expended during the demands of day-to-day life. Siegel's own theory: "the main function of sleep is to increase an animal's efficiency and minimize its risk by controlling how a species behaves with regards to its surroundings" is adequately simple. Brain temperature drops from waking levels during non-rapid eye movement (non-REM) sleep and rises during REM sleep. If we miss a night of sleep, we usually feel moody and tired until we once again get the chance to go to sleep. The premise is that the core function/s of sleep, rather than its secondary/derived functions, enabled the conservation of sleep throughout evolutionary history by conferring advantages significant enough to outweigh the numerous .

In a new study, researchers identified a sleep-like state in a tiny, freshwater animal called a hydra, which has a simple anatomy and lacks a brain. PMC Unfortunately, this is not the case; however, several hypotheses have been proposed to explain the function of sleep. If the 8 hours are carried out in a continuous manner, it will take about 4 or 5 cycles. 2006. Although todays predator for humans may be more of some environmental stressor, the remaining result (falling asleep unexpectedly) can still occur. Invertebrates such as insects show periods of rest that are similar to sleep in more complex organisms. Does the story above sound familiar? This type of rest did not allow for long durations of sleep because the locations were vulnerable to predators or to other environmental disturbances.

So what about the role that sleep played in evolution? This paper presents a brief historical review of the beginning of scientific studies on sleep research and evaluation of the electrophysiological basics. Uni-hemispheric sleep may have developed as a way of dealing with the danger of predators that can suddenly approach from any direction in the air or in the sea. This theory suggests that sleep is a behaviour which enhances our overall survival. Would you like email updates of new search results? 2022 May;52(3):511-525.

Within the first billion years or so of the Earth's history, self-replicating chemical processes began. A highly stable nest greatly increased the duration and quality of sleep, which led to even more brain development in early humans. So dreaming is still an unknown within an unknown. Sleep, it has been proposed, evolved because there is a universal core function that cannot occur during wakefulness. The evolutionary approach has also been called the ecological approach. Higher quality sleep also enabled humans to sleep for a shorter part of the day, giving them more time for learning, socializing, and defending their communities. Evolutionary explanation of sleep suggests there four mains reasons for it, energy conservation, foraging requirements, predator avoidance and to waste time. NPR Radio Interview.

Encyclopedia of Sleep and Dreams: The Evolution, Function, Nature, and Mysteries of Slumber explores the evolution, nature, and functions of sleep and dreams. Sleep duration is not related to brain size or cognitive ability. Most attempts to explain the evolution of sleep, a vulnerable state observed across diverse taxa, have tended to focus on a search for benefits associated with physiological or vital functions. R01 HL041370/HL/NHLBI NIH HHS/United States. Despite the revolutionary developments that each of these, and many other scientists and political leaders have brought to the modern and post-modern world, many would argue, convincingly, that none have shaken the foundations of our belief systems and had such far reaching impact on other fields of science, technology and culture as Darwin. He suggested that sleep helps animals to stay out of the way of predators during the parts of the day when they are most vulnerable. A second theory proposes that our sleep patterns evolved as an adaptive response to predatory risks, which increase in darkness. This book discusses the evolution of sleep and its possible function in the higher invertebrates and vertebrates, including humans. ASU - Ask A Biologist. Later on, with the evolution of complex brains, sleep may also assume importance in development and maintenance of these structures. More recently, scientists have begun to wonder whether this evolutionary explanation of sleep can also explain some of the more common sleep problems that people have today. It implied that quiet sleep was the original form of sleep and that REM sleep was a relatively advanced physiological trait. Additional images via Wikimedia Commons.

It also involves a homeostatic function in that the longer an animal has been without sleep or the greater the stress it has experienced, the deeper the state of rest becomes. Nature. function of sleep. 1998. Darwin was not the first to consider evolution or the only one to consider natural selection to be its mechanism. This certainly fits with the experience of insomnia, during which people have lighter sleep due to stress and over-arousal. Conference Schedule *Agenda may be subject to change. Indeed, a theory supporting the biological function of dreams has a steep hill to climb, as we don't really have a complete theory for the biological function of sleep.

Hence, special emphasis is placed on the influence of NONREM and REM sleep on the reorganisation of neuronal networks. 2001 Nov 2;294(5544):1058-63. doi: 10.1126/science.1063049. Scientists believe that this improved sleep quality eventually led to enhanced brain function, which increased intelligence in great apes. In addition, predator and prey animals generally develop a symbiotic relationship. But he did carry out what is by far the most extensive research in this area, and organized and published his findings in a way that captured people's interest. ", American Psychological Association.
