Recently, there has been a great deal of advancement in the interesting topic of sleep science. The science of sleep includes the following important areas: The first thing to note about sleep is that it happens in cycles, lasting between ninety and one hundred minutes each. One stage of rapid eye movement (REM) sleep and three stages of non-REM sleep make up each cycle. 2. Dwelling Phases: Brain wave slowing is a hallmark of Stage 1 NREM, which is the change from wakefulness to sleep. During the second stage of NREM sleep, the body cools down and the heart rate decreases. – Stage 3 NREM: Deep sleep, sometimes referred to as slow-wave sleep, has brain waves that are even slower and makes it harder to get up. Muscles become paralysed, dreams arise, and brain activity rises during REM sleep.
Sleep-Wake Homeostasis: The body’s internal clock controls when it is awake and asleep. It builds up a need for sleep during wakefulness and releases pressure to sleep when it is asleep.
4.Circadian Rhythms: The suprachiasmatic nucleus (SCN), which reacts to light and dark cues from the surroundings to synchronise our physiological processes with the twenty-four-hour day-night cycle, is in charge of the body’s internal clock.
5.Sleep Disorders: Narcolepsy, sleep apnea, insomnia, and restless legs syndrome are common sleep disorders that can negatively affect a person’s quality of life and general health.
6.Sleep and Brain Function: Emotional control, learning, and memory consolidation are all significantly impacted by sleep. Lack of sleep can affect mood and cognitive performance.
