Sleep Study: Can a Sleeping line Tell What a Person is Actually Doing?
The human brain functions in a sort of two-phase cycle. While you are asleep, your brain undergoes sleep, starting with NREM sleep that is nonrapid eye movement sleep, and then progressing to REM sleep is rapid eye movement sleep.
What’s NREM sleep?
This is the phase of sleep which is usually not remembered by us. Various physicians and Sleep scientists suggest that there are seven different stages of sleep. Alpha (Stage 1) is the first stage of sleep, which is followed by the Theta stage(Stage 2) and then the Delta stage(Stage 3,4). Theta Sleep is also known as the Dream state of humans. When we go to the deeper levels of sleep, our brain’s pattern is changed to Delta waves, after which it starts to become hyperactive, and we start to dream. Now is the time when we enter REM sleep.
What’s REM sleep?
This is that part of sleep that we usually remember as dreams. The period that the brain is in this “in a dream” stage differs for every person. While dreaming, the mind is not in a total state of work, but it is more like a “zone” where the mind is relaxed. During this sleep, the Alpha Beta and Theta waves are produced by our brain.
What causes disturbances in the sleep cycle/ sleeping line?
People have trouble sleeping because the REM sleep state is disturbed by various things like stress, worrying about the day’s work, the tension in the neck and muscles, lifestyle disturbances, and psychiatric disorders like depression, mania, schizophrenia, etc.
People who are slightly awake but are having trouble sleeping are often confused with rem sleep. When you are dreaming, you are both awake and very sleepy at the same time. So you cannot be asleep or awake at the same time. People can become sleepy in their REM sleep when they do not get enough rest and do not go back to their regular sleeping pattern. It helps you improve your sleep quality if you get a proper proportion of NREM and REM sleep.
What did studies find out about the sleep cycle/ sleeping line?
Studies show that the number of neurons that fire during non-REM sleep is larger than the number of neurons that fire during REM sleep. Various experiments have established this difference in neuron firing. One of the most exciting experiments was done by James Parkinson, where he asked volunteers to watch a moving video while their feet were strapped to a device that is reading their brain waves. The participants slept while the video was playing, and their brain activity was recorded. The researchers found that the amount of time that the participants slept and their REM/NREM cycles matched up.
B.F conducted another experiment in humans with REM sleep. Skinner. He found that children who learned to ride a ladder after being taught to sit would sit longer and learn more things than children who had never been taught to sit. The difference between the two groups of children was that the group who had never been taught how to sit had more splendid delta waves during REM sleep. This was because the delta waves were synchronized with stage five of the human REM cycle. In short, those individuals who had the highest level of delta waves during REM sleep had the most remarkable ability to remember the information that they had learned.
In a related experiment, Dr. Michael Perlis showed that the amount of time someone sleeps and their delta waves are similar. This research was based on recordings of someone’s brainwaves while he was either asleep or awake. Dr. Perlis distinguishes delta waves, which occur during REM sleep, and beta waves, which occur during deep sleep. Those who have a more significant amount of beta waves are believed to experience more vivid dreams. These studies provide the basis for many of today’s sleep study methods as they attempt to understand the process of sleep better.
So what is healthy sleep? | What is a healthy sleeping line?
Asleep of a minimum of 8 hours in the absence of any light source in surroundings, with ample NREM and REM sleep in required proportions, is the minimum sleep provided to our brain. The quantity but the sleep architecture that is the quality of sleep is also essential to be maintained, In the presence of distortions of which we suffer from laziness, lifestyle problems, and psychological illnesses.
