The Difference Between REM and Deep Sleep
All sleep is not the same. You’ve probably heard about light sleep and deep sleep, and many often equate deep sleep with REM sleep. Just as light and deep sleep are different from one another, REM and deep sleep are two completely different sleep stages, each with defining characteristics. There are five different stages of sleep, all which contribute to your body’s circadian rhythm, or natural body clock. REM and deep sleep are stages three and four of sleep.
Rapid eye movement, or REM sleep, is the deepest sleep stage. The eyes move more rapidly in all directions during REM sleep, as its name indicates. REM is the fourth stage of sleep.
Deep sleep is non rapid eye movement, or NREM. There are three other NREM stages as well. Other names for this deep sleep stage are slow-wave sleep, delta sleep, and N3 since this is the third stage of sleep.
In order to get your best sleep yet, you’ll need a sleep tracker like Eight’s that analyzes your nightly sleep data and tells you exactly how much sleep you’re getting in each stage. Sleep trackers compare this information to how much time of each sleep stage your body actually needs. By following the simple steps sleep trackers suggest such as avoiding caffeine before bed, you can help regulate your sleep and improve your overall sleep health.
