Five Stages Of Sleep

Table Of Contents


The majority of us think that when we fall asleep, our body simply slows down and relaxes,resting and recharging in readiness for the next day, now while this in part true, the actual sleep process is anything but calm and restful

Our nights sleep is actually made up of five stages; all are very different and surprisingly active –

As we progress through these stages, our body is anything but inactive; our brain activity changes along with our body temperature as our body repairs and refreshes our muscles, cells and brain in readiness for the coming day

The stages are collectively known as Sleep Architecture and in ideal conditions run over an 8 hour cycle.

Stage One

The first stage of sleep, we are actually somewhere between consciousness and sleep, our brain produces very slow brain waves known as Theta Waves. If we were to be disturbed during this stage, we would not feel rested at all.

The second stage of sleep usually lasting about 20 minutes, the brain starts to produce fast rhythmic waves called Sleep Spindles, along with this, our hear rate slows and our body temperature reduces.

Stage Three

During this stage we slip from light sleep into a deeper one, our brian waves slow down and become Delta Waves which have a much lower frequency and higher amplitude. During this stage our heart and breathing rate are at their slowest.

Stage Four

Thought to be the most restful part of sleep, and often referred to as Delta Sleep. During this stage our blood pressure reduces and our muscles relax, the blood flow into the muscles increases, helping to refresh and restore.


Stage Five

Called REM sleep, this stage has the most brain activity and is when most dreams occur.

During REM sleep our brain processes our memory, and boosts its natural supply of dopamine and serotonin which amongst other things,help to balance our moods during the following day.

Not Always In This Order

These stages do not necessarily follow each other in this order, often after going through REM sleep we can drift back to stage two and then repeat the cycle in differing orders. The REM stage of sleep is usually the longest.

A Full Nights Sleep Is Important

With all these stages; its little wonder that disturbed sleep can have such a detrimental effect on our health, sufferers can often experience anxiety, stress and even memory loss. Extended periods of sleep problems can ultimately lead to a hard to break habit that could seriously affect our general health
