Sleep is essential to your health and well-being. Having a comfortable new mattress and keeping a regular bedtime are just a couple of ways to get a good night’s sleep. However, how long you sleep may not be the best indicator of quality of sleep. To see the importance of sleep and how your body behaves when at rest, explore the following overview of the function of sleep stages.
What are sleep stages? Sleep patterns differ with each individual and change as you get older. However, in a basic sleep cycle, you should experience three stages of non-rapid movement sleep (NREM), a stage of deep delta sleep, and one final stage of rapid eye movement (REM) sleep. When you complete a full 90- to 110-minute cycle, your body will start over and begin again with Stage 1 NREM sleep.
What occurs during each sleep stage? Each sleep stage causes different physiological reactions in your body. NREM is the first phase of sleep your body slips into and is the lightest stage of sleep. As you continue through the NREM sleep stages, your eye and muscle activity decreases, while your brain activity increases. In the last stage of NREM sleep, you experience deep sleep, which is when your brain emits delta brain waves and your body regenerates and repairs itself. REM is the unique final sleep stage in which most of your dreams take place; during REM sleep, your brain and other physiological systems dramatically increase in activity.
How does each stage affect overall quality of sleep? Sleep disorders are determined by whether you properly cycle through these sleep stages. Skipping a stage can bring about serious health issues. In addition, sleep deprivation can lead to memory problems, emotional issues, changes in weight and heart rate, and the development of type 2 diabetes. It is important to understand your sleep health so you can be sure to get the most out of each night’s rest and maintain your overall health.
