What Is NREM Sleep?

REM sleep is the process of phases in which there is low physical movement, and the propensity of the sleeper to dream vividly. The phase is also known as paradoxical sleep and sometimes desynchronized sleep because of the physiological similarities to being awake, including rapid, low-voltage desynchronized brain waves. The right and left hemispheres of the brain are more coherent in REM sleep, especially during lucid dreams. Two other neurotransmitters seem to promote wakefulness, diminish during deep sleep, and inhibit paradoxical sleep. Unlike the abrupt transitions in electrical patterns, the chemical changes in the brain show continuous periodic movement. NREM Origins and Description
The theories to explain where NREM sleep originated,
We need to rest our body and mind from an active day so we may do so tomorrow. The problem is, sleep researcher actually are not sure why we actually need sleep (Cirelli and Tononi, 2008). Sleeping has a physiological process that restores and rejuvenate the body and the mind. It also provides much rest for muscles and body. Sleeping is also believed to maintain the immune system function, improve cognitive abilities, as well as helping regulate moods and emotions. When to examine the sleep patterns of other species, they come to find that this explanation of sleeping does not work with other species sleeping patterns. However, some have taken on the view that by examining animals in their environment explain to researchers that sleep is developed by the result of evolutionary adaptation (Roth and others, 2010; Siegel, 2009). Comparing a lion to a zebra, research has shown that lions can sleep up to 15 hours in one day as when a zebra and other animals that are preyed upon show to sleep less due to survivalist nature against its predators. To briefly conclude, sleep as of now is an evolutionary adaptation in which a species rests ones body and mind and depending on the evolutionary level in which the species is at, the greater benefits of retaining more sleep and has an evolutionary advantage over the other
The 4 stages describe in detail of how brain activity regulates as we fall into a deep slumber and how that the neuro and psychological activity can produce such a phenomena that has caused significant interest since the beginning of time. These psychological phenomena’s take up a large portion of our lives and has influenced many of their beliefs in their daily lives. However, the study of why we dream is still not answered, but as for sleep it is shown that it is an evolutionary adaptation to cope with the everyday environment that you are present in. Sleeping and its processes play a huge role in cognitive abilities such as helping with learning, moods and emotions, physical energy, and it removes toxins from the mind and body. Technology advancement from EEG scans reveal that sleep can help with memory and of course, even improve your happiness. Studies show that sleep deprivation can cause major harm in going about your daily activities such as insomnia, depression, anger and frustration, and
