Brain Activity During Sleep

Brain Activity During Sleep: Doctors always say that one should at least sleep for 8 hours in the night out of a Total of 24 hours. Though it looks entirely the wastage of time to lie motionless for 6-10 hours in a semi-conscious state. But the fact is, sleep is the most important cycle of the whole day as mind and body actually do some amazing things while one is snoozing.

When we take a sound sleep, we wake up feeling refreshed and is prepared for our daily activities for the new day.

During the day, our mind works with an amazing speed, with all kinds of thoughts, positive, negative, problem solving, problem giving, daydreaming, our mind is constantly working without stopping in between. Now it is the time one should know what exactly the mind and body do when one is asleep. Sleep has a major influence on our overall quality of life (Brain Activity During Sleep).

To get the best out of our mind than sleep in terms of both quantity and quality are important. Teens need at least 8 hours of sleep and on average, uninterrupted sleep at night is a must to keep their bodies and minds re-energized for the next day.

If one tries to cut short the sleep the body will face a shortage of time to complete all of the phases needed for muscle repair, memory consolidation and release of hormones regulating growth and hunger. Then finally we will wake up inactive, less prepared to concentrate, make decisions, or engage fully in school, workplace and social activities.

Contribution of Sleep Pattern

Sleep shows an irregular pattern of REM (rapid eye movement) and NREM (non-rapid eye movement).NREM in sleep works in a sequence that repeats itself about every 90 minutes throughout the night.

The role played by each state and stage of sleep

Non-rapid eye movement: As we begin to fall asleep, we enter NREM sleep, which is composed of stages N1- N4. 75% of the night is spent in this state.


  • Between being awake and falling asleep
  • Light sleep


  • Onset of sleep
  • Becoming disengaged from surroundings
  • Breathing and heart rate are regular
  • The temperature of the body gets lowered so sleeping in a cool room is preferred.


  • Deepest and most restorative sleep
  • Blood pressure drops
  • Breathing becomes slower
  • Muscles are relaxed
  • Blood supply to muscles increases
  • Tissue growth and repair occurs
  • Energy is restored
  • Hormones are active at this crucial time, such as Growth hormone, essential for growth and development, including muscle development

REM (25% of night): First occurs about 90 minutes after falling asleep and repeat about every 90 minutes, getting longer later in the night

  • Provides energy to the brain and body
  • Supports daytime performance
  • Brain is active and dreams occur
  • Eyes project back and forth
  • The body becomes steady and relaxed, as muscles become inactive.

Other amazing features during sleep

  • In addition to the above the levels of the hormone cortisol dip at bedtime and enhance over the night to help for alertness in the morning.
  • Sleep helps us to prosper by contributing to a healthy immune system.
  • It can also balance our appetites by helping to regulate levels of the hormone’s ghrelin and leptin, which play a major role in our feelings of hunger and fullness. Hence, when we undergo poor sleep, then we may feel the need to eat more, which can lead to weight gain.

Brain Activity During Sleep

It locks in what you’ve learned

While one is asleep, the brain returns information that may not have been able to stick earlier. Experts call this association (making one’s mind stronger), and is most important for safeguarding our memory. This can also help enhance our ability to learn while we are awake. If wanting to learn a new language, our brain will help master that skill even when we are sleeping.

It repairs itself

Throughout the day we are continuously working in some or the other form and our body is constantly being broken down. Muscles fatigue, joints ache, and our brain too, scrambles. Sleep allows our body to put itself back together. It’s also the primary time when our body fixes our heart and blood vessels.

Stores and creates memories

During sleep, our brain is busy creating new memories, uniting older ones, and linking more recent with earlier memories. This phenomenon exists in both the state of our REM (Rapid Eye Movement) and non-REM sleep. Lack of sleep can damage your hippocampus, an area of the brain for memory creation and consolidation. So, make sure you give your body a break, go to bed at the proper time and help your mind grow stronger.

Organizes our memories

Throughout the day, our brain processes an unintelligible amount of information. During the day it makes a puzzle of information to go through sleep puts the pieces together. It helps process new things that one had learned as well as a collection of things that one needs to remember later.

Helps your brain perform better

REM also called deep sleep, it is of utmost importance to help in figuring out complex problems, identify patterns, and recall information. In fact, the amount of time one spends in deep sleep has a direct correlation with how well one performs certain tasks.

It cleans out toxins

Yes, it is absolutely right. Our mind takes out the trash while we are asleep. Our brain loves us and it doesn’t mind doing a little housekeeping while one snooze away. While one is sound asleep, we are allowing our brain to flush out toxic molecules that get built while we are awake. If we don’t give ourselves enough sleep, then our brain can’t clean out those damaging molecules. Then this can ultimately lead to Parkinson’s and Alzheimer’s problems in one.

Keeps you sane

Researches figured out that if you go 24 hours without sleep, you’ll start to exhibit the same symptoms as schizophrenia (Brain Activity During Sleep). That means that without sleep, your brain starts to exhibit the same problems as people with severe mental illnesses.  So, make sure to give our body a break, try to go to sleep at, improper hour and help the mind grow stronger.

You become paralyzed

During REM sleep, one literally cannot move a muscle. Your breathing and your eyes are not paralyzed; however, the rest of our body is. In this deep form of sleep, our brain is preventing our body from jumping off the side of the bed.

Helps reduce inflammation

Inflammation rears its ugly head in tons of Different forms. It can cause digestive disorders, headaches, and even physical and psychological degeneration. Sleeping too little actually results in many of the same problems as poor diet and sedentary behavior. Sleeping helps regulate hormones that keep away bad problems like hypertension, cardiovascular disease, and diabetes.

It helps one to create day-to-day routines

During our deepest sleep, our brain replays the memories of our day-to-day routine and helps to re-establish the order in which those things occurred. The more we routinely do something, our brain will process those actions to be our standard. If we eat healthily, do a workout, take a dog on a run or paint after work our brain will make this our day-to-day task. Practice makes things permanent. Next time someone boasts you about how little sleep he or she gets every night, just ignore and keep taking 8 hours of sleep. Sleep is an important part of the daily cycle, and without it, our body can’t function properly. Our brain does so much for us, so it’s time to help it by taking proper sleep.
