While we do cycle through all stages of sleep throughout the night, the majority of our sleep time is spent in Stage 2 sleep. This stage is characterized by slower brain waves with periodic bursts of rapid brain waves called sleep spindles. It is also during this stage that our body temperature decreases, our heart rate slows down, and our muscles relax. REM sleep, also known as Rapid Eye Movement sleep, is the stage where most of our dreaming occurs and is often associated with consolidating memories and processing emotions. However, REM sleep only accounts for about 20-25% of our total sleep time. Stages 1 and 4 sleep are less common and make up an even smaller percentage of our overall sleep time.
