As we wind down to sleep and fall asleep it is full of activity happening in our brain and body, from physical recovery and memory consolidation to dreams.
After you fall asleep your brain goes through four stages of sleep that are crucial to getting a good night’s rest. The endless tossing and turning during the night, trying to get to sleep is annoying as well as disruptive and frustrating. Along with the quantity of sleep the quality of sleep is crucial. The ability to move through various phases of sleep determines whether you’re getting enough sleep or not.
Before you jump into the stages of sleep, let’s be aware.
What’s the nature of the sleep cycle?
Sleeping patterns are not constant. The total amount of time you night’s sleep is comprised of several stages of your sleep cycle comprised of four phases. In a typical night, you will go through between four to six cycles of sleep. The sleep cycles might not be the same length, however they will run for about 90 minutes.

Sleep Types:
Our brains constantly cycle through various kinds of REM and non-REM sleep, in an order that is specific to. Of course, I’ll discuss the meaning of this further.
The REM sleep is characterized by an intense eye movement that is connected to dreams as well as the body’s responses and reactions to these. It can last from between 90 minutes and 2 hours.
Non-REM sleep is a form of non-rapid eye movement. It has three phases, starting from getting sleepy, to the time of deep sleep required to replenish energy to face the day ahead. It is comprised of three stages that are based on the study of the brain’s activity during sleep which reveals distinct patterns that define each stage. Each stage is about 5 to 15 minutes.
4 Stages of the Sleep Cycle:
1st Stage: The stage is known as N1, which refers to the time when people first fall asleep. This stage usually lasts for about 1-7 minutes.
At this point the brain and body activities slow down by a few brief moments of movement. There are minor shifts in your brain’s activities that are associated to sleep. It is not difficult to wake someone up during this stage of sleep. As the night progresses a person who sleeps in peace may not be able to stay for long in this stage.
2nd Stage: This stage can also be known as N2 because the body goes into a relaxed state. The initial sleep time is 10-25 minutes, and it gets longer with each cycle of sleep throughout the night.
There will be a decrease in the temperature, relaxed muscles and a slowing of heart rate and breathing during this phase. The brain slows down its the rate of activity and ceases eye movements.
3rd Stage: In the stage of N3, it’s harder to wake someone up when you are currently in the state. The typical duration is between 20 and 40 minutes during sleep cycles in the early hours and, as you sleep this stage will get shorter.
The stage is also referred to as deep sleep. It is a time when your pulse, muscle tone and breathing rate reduce when the body is relaxed more. It is believed that brain activity throughout this phase is characterized by a distinct pattern. Experts believe that this period is crucial for a restful night’s sleep, which helps the body recuperate and develop. It also aids in the immune system, as well as other crucial bodily processes.
Following this it is time to slowly drift to REM sleep. You begin to dream.
4th Stage: During the stage known as REM your brain activity speeds up to the point that brain scans give the impression as if you’re awake. The cardiovascular rate, blood pressure and breathing speed up. When your eyes whirl between sides your body’s muscles are completely paralyzed. The most vivid and story-like dreams are experienced during REM sleep, as if your brain is believed to be replaying emotions.
What are the effects of the stages of sleep?
Age Baby’s generally enter into the REM stage when they go to sleep for a longer time, whereas adults are more likely to stay in less REM sleep.
Alcohol Abuse Alcohol, sleep pills and antidepressants disrupt your normal sleeping patterns. They reduce REM sleep, which occurs early at night.
Disorders Neurodegenerative diseases like Parkinson’s disease and similar conditions can cause multiple awakenings and disrupt a normal sleep cycle.
While you can’t manage your sleep patterns, you can increase your chances of making steady progress through each stage of sleep. The most important thing is to concentrate on improving your sleep hygiene , which is a result of your environment at night and sleep practices.
