The duration of REM sleep is related to body temperature

Summary: Research reviews that warm-blooded animals with increased body temperatures have much less REM sleep, whereas these with decrease body temperatures have extra REM sleep. According to researchers, REM sleep acts like a “thermostatic mind heater.”

Groups of warm-blooded animals with increased body temperatures have much less fast eye motion (REM) sleep, whereas these with decrease body temperatures have extra REM sleep, in accordance to a brand new examine by UCLA professor Jerome Siegel. works like a “thermostatically managed mind heater”.

School 12 months Lancet Neurology A beforehand undetected hyperlink between body temperature and REM sleep, the interval of sleep when the mind is most lively, stated Siegel, who directs the Sleep Research Center at UCLA’s Jane and Terry Semel Institute for Neuroscience and Human Behavior.

Birds are warm-blooded or homeothermic animals with the very best body temperature of 41 levels Celsius, and get no less than 0.7 hours of REM sleep per day. This is adopted by people and different placental mammals (37 levels, 2 hours of REM sleep), marsupials (35 levels, 4.4 hours of REM sleep), and monotremes (31 levels, 7.5 hours of REM sleep).

Brain temperature drops throughout non-REM sleep after which rises throughout REM sleep. This sample “permits homeothermic mammals to preserve vitality throughout non-REM sleep as a result of the mind is not responding to menace,” Siegel stated.

The quantity of REM sleep in people is neither excessive nor low in contrast to different homeothermic animals, which “challenges some well-liked views suggesting a job for REM sleep in studying or emotional regulation,” he stated.

Funding: Siegel’s analysis is supported by grants from the National Institutes of Health (HLB148574 and DA034748) and the Medical Research Service of the Department of Veterans Affairs. He has declared no competing pursuits.

Abstract

Sleep perform: an evolutionary perspective

This shows the outline of the head

Prospective epidemiologic research in industrialized societies counsel that 7 hours of sleep is optimum for individuals aged 18 years and older, and that increased and decrease quantities of sleep predict shorter lifespans. People residing a hunter-gatherer life-style (for instance, tribal teams) sleep 6-8 hours an evening, the longest sleep in winter.

The prevalence of insomnia in hunter-gatherer populations is low (about 2%) in contrast to the prevalence of insomnia in industrialized societies (about 10-30%). Studies of sleep problems, designed to perceive sleep perform, are sometimes confounded by the consequences of stress.

Consideration of spontaneous each day sleep durations starting from 2 to 20 h throughout mammalian species might present vital insights into sleep perform with out separation stress.

Sleep duration is not related to mind dimension or cognitive means. Conversely, sleep duration throughout species is related to their habitat and dietary necessities, suggesting a job for wake-sleep stability in meals acquisition and vitality conservation. Brain temperature falls beneath waking ranges throughout non-rapid eye motion (non-REM) sleep and rises throughout REM sleep.

Average each day REM sleep time in homeotherms is negatively correlated with common body and mind temperature, with the very best quantity of REM sleep in egg-laying (monotremes) mammals, medium-sized marsupials, and to a lesser extent placental mammals and birds.

Therefore, REM sleep might play a key position in regulating mind temperature and metabolism throughout sleep and facilitating wakefulness.
