Most of us awake each morning and rarely remember too much of our night’s sleep nor rarely consider what has been going on inside our bodies during the last 8 or less hours. We only know if we awake refreshed feeling or groggy! Let’s take a sneak preview of what really goes on at night…
There are 5 distinct stages of sleep, each serving a unique purpose. Stages 1-4 are referred to as the non-rapid eye movement sleep (NREM) and the 5th stage is the rapid eye movement sleep (REM). These stages are repeated between 5-6 times each night.
The first cycle of sleep allows us to spend a long time in deep sleep (stages 3 and 4) and a shorter time in REM sleep. As the night progresses and the cycles continue, REM sleep periods become longer and the deep sleep periods get shorter. As the morning light begins to appear, our body approaches wakefulness, pushing deep sleep away almost completely and our brains go between stages 1 and 2 and REM sleep.
Here follows a quick description of each stage:
-
Stage 1 - This is where the brain and body relax, breathing becomes more regular and muscle activity gradually decreases. This stage mostly serves as the transition between sleep and wakefulness. It is a very light sleep.
-
Stage 2 - This stage accounts for approximately 50% of all sleep time. The heartbeat and respiration slow and become very regular and the sleeper’s body relaxes more deeply.
-
Stage 3-4 - These are deep sleep stages. The sleeper is very relaxed, with a slow regular heartbeat and breathing. Most of the body’s necessary repair work occurs during this stage.
-
Stage 5 or REM sleep - Most of the dreams occur at this point. Heartbeat speeds up and breathing rate increases and the body actually becomes temporarily paralyzed which prevents the physical acting out of dreams. This stage is around 20-25% of total sleep time in an adult.
To carry you through all these stages of sleep, our memory foam pillows are here to support and comfort you.
