Getting enough sleep is essential to achieving optimal health and maintaining overall well-being thus, the inability to get enough sleep can take a toll on your health.

People of all ages suffer from sleep loss, insomnia, and poor sleep quality, which lead to several mental and physical health issues. The main causes behind it are a sedentary lifestyle, professional work stress, and several personal reasons.

While the duration of your sleep is important, you shouldn’t neglect the sleep quality to comprehend whether the time you slept sleeping was rewarding or not.

Sleep comprises several stages into which human beings keep oscillating while they are asleep forming a sleep cycle. Let’s understand it in a better way.

What is Sleep Cycle? 


Sleep is not uniform but comes in the form of cycles that progress smoothly from each of the four different sleep stages of non-uniform length. Each stage plays a crucial role in keeping your mind and body at rest to stay refreshed all day long.

The four sleep stages are classified into two broad categories- rapid eye movement (REM) sleep and non-REM (NREM) sleep. The four different stages depict distinct brain activities during sleep and are discussed below. 

#1. Dozing off

Stage 1 / N1 is what we generally call the dozing-off stage, which typically lasts five to ten minutes. Here the body is not in a completely relaxed state, but the body and brain activity slows down. An individual can be easily woken up in this stage. If not, they will quickly transition into stage 2.

#2. Light Sleep

Stage 2 / N2 is characterized by a drop in the body temperature and muscle relaxations. The breathing and heart rate gradually slows down as the body enters a quiet stage with no eye movements. Stage 2 lasts for up to 10-25 minutes, and the brain activity slows down and can get even longer during the night time. 

#3. Deep Sleep

Stage 3 / N3 is what we call deep sleep, and waking up someone in this phase becomes even harder. The muscles relax further, and the pulse and breathing rate decrease even more in this stage.

The brain activity shows a familiar delta wave pattern. It is in this stage that the body recovers, grows, and strengthens the immune system.


#4. REM Sleep  

In the REM Sleep stage, the brain activity shows signs of acceleration, and the human body undergoes atonia, a condition when the complete body, except your eyes and breathing muscles, gets paralyzed. This stage strengthens the cognitive abilities of the brain to boost functions like learning, memory, and creativity. 

Fascinating, right? Sleep is indeed mysterious, and monitoring it is a complicated task. 


Thankfully we have several competent sleep trackers that assist you in monitoring your sleep patterns and help ensure you are getting enough quality sleep. These statistics help figure out the root causes behind such issues and indicate whether you need any medical aid.
