![]() The pons is responsible for causing this temporary paralysis as they shut off neurons in the spinal cord. Researchers have also found that during REM sleep, our body can experience a state of temporary paralysis, which inhibits our muscle activity (3). This is the outer layer of the brain that is responsible for thinking, learning and consolidating information. Signals from pons are sent to the thalamus, which sends them to the cerebral cortex. REM sleep begins in an area at the bottom of the brain, called pons. This phase of sleep accounts for 25 percent of an adult’s life cycle and over 50 percent of an infant’s (2). People enter REM sleep in the first 90 minutes of their sleep cycle, and the eyes are continually moving in various directions. During our sleep cycle, the brain travels through five different stages of sleep, and one of them is rapid-eye-movement (REM) sleep. This discovery of dreaming was then found in most mammals, suggesting a new phenomenon that animals regularly dream during their sleep. In 1953, Aserinsky and Kleitman indicated that dreaming was related to eye movements during sleep that they called REM sleep (2). Dreaming mostly occurs in this stage, with increased respiration rate and increased brain activity. This is REM sleep, where rapid eye movements occur while you’re sleeping. To learn all about Deep Sleep and how you can increase it read our article " What Is Deep Sleep?" Stage 5 Sleepwalking and bed-wetting typically happen at the end of Stage Four sleep. Stage Four is a deep sleep that lasts for about 30 minutes. This is commonly known as 'Deep Sleep' or ‘Delta Sleep’, because of the delta waves that occur during this time. It's a transitional period between light sleep and very deep sleep. In this stage deep and slow brain waves known as the Delta Waves begin to emerge at this point. Body temperature begins dropping and heart rate starts slowing down. Our brain begins to produce very short periods of rapid, rhythmic brain wave activity known as ‘sleep spindles’. In this stage your muscles relax further, but you are still in light sleep. This is also a non-REM sleep, which lasts for about twenty minutes. Brain waves also get slower, as your brain starts to relax from your daytime wakefulness. Eventually your muscles relax and occasional twitches. This usually lasts for several minutes as light sleep, with slow heartbeat, breathing and eye movements. This is the first stage of non-REM sleep where your brain travel from wakefulness to sleep. ![]() During the night, humans cycle through all stages of non-REM and REM sleep several times, with longer REM sleep periods towards morning. Every stage is linked to a specific neuronal activity and brain wave structure. Non-REM sleep has further three different stages. It will also focus on ways we can improve our REM sleep so that we can improve the overall quality of our sleep by using our 20 suggested strategies.Īccording to the NIH (2), there are two main stages of sleep: rapid eye movement (REM) sleep and non-REM sleep. This article will focus on explaining what REM sleep is, which is associated with dreaming. ![]() But, have you ever wondered what sleep stage is related to dreaming and forming memory? If you have, you are in the right place. However, sleep has different stages: NREM Alpha, NREM Theta, NREM Delta and REM. Thus, we need to understand and improve our sleep cycle. Research has shown that poor sleep can lead to anxiety, depression and sleep disorders (1). ![]() Sleep is necessary for vital human cognitive functions such as sustained attention, vigilance, emotional processing and working memory. Humans spend about one-third of their life sleeping, indicating a crucial role it plays in our life. South Georgia & South Sandwich Islands (GBP £)
