What Are The 4 Stages Of Sleep- And How A Good Mattress Can Help You

Every night you go to sleep you begin your journey through the different cycles of sleep. Though you are fully unaware of what is happening while you sleep or snooze, your body and your brain are still very much active and are busy working away.

Each cycle of sleep plays a very different role in how you will feel the next day. Below we take a look at the cycles of sleep including the stage that helps your brain, the cycle that restores your body and if you have that good balance between each stage of sleep.

So What Are The Stages of Sleep?

Sleep has always been traditionally divided into 4 categories: awake, light, deep, and REM sleep. Each one plays an important role in bot maintaining your mental and physical health.

The stages of sleep are as follows:

  • Awake
  • Light sleep
  • Deep sleep
  • REM Sleep

REM sleep stands for rapid eye movement and is also known as stage R

Light and deep sleep can be grouped together as ‘NREM’ which basically means non-rapid eye movement sleep or as they are more commonly referred to as stages 1-4

So What Does Each Stage Do?

Each stage of sleep plays a vitally different role in preparing your body for following next day.

Awake time as an example happens before you fall asleep and after you fall asleep. It also includes those brief awakenings during your sleep.

During the light sleep cycle, your respiration slows down and your heart rate decreases, your body temperature also drops and waking up is much easier.

The deep sleep cycle promotes muscle growth and body repair. It also flushes out brain waste and shows long, slow brain waves.

REM Sleep supports your brain. During the REM cycle is where vivid dreams occur and your body becomes immobile (you can’t move) which stops you acting out your dreams (kicking out etc). It also improves your memory, your learning abilities, and also your problem solving.

So What Does A Normal Night’s Sleep Look Like?

The amount of each phase of sleep can vary quite significantly between nights and the individual. During an ideal night’s sleep, your body will have enough time to go through four to five of the 90-minute cycles that sample different phases of sleep as the night progresses.

In general, each cycle moves sequentially through each stage of sleep: wake, light sleep, deep sleep, REM, and repeat. Cycles earlier in the night tend be more a deep sleep while later cycles have a higher proportion of REM. By the last cycle, your body may even choose to skip deep sleep altogether and has decided that the time is right to come out of sleep or simply wake up!

Deep sleep tends to occur more in the first half of the night’s sleep while REM tends to occur during the later sleep cycles.

Overall, your body will spend the majority of the night in a light sleep. How much time you spend in REM or deep can vary quite a lot and depends on the individual but below we outline the averages you can expect for each cycle in a single night’s sleep.

You will spend an average of 2-5% of your sleeping time awake

You will spend on average of 45-55% of your sleeping time in light sleep

You will spend an average of 13-23% of your sleeping time in deep sleep

You will spend an average of 20-25% of your sleeping time in REM

It is more than normal to spend most of your night’s sleep in a light sleep.
