Experts say that 7 to 9 hours of sleep every night is ideal, but more than a third of US adults get less than that. Sleep apnea is one of the more common reasons for disrupted sleep, as the cessations in breathing repeatedly force you to wake up for air – and that means you’re missing out on the full benefits of a good night’s rest. In this post, you’ll learn more about the 4 stages of sleep in Greenfield and why they’re so essential if you want to wake up the next morning feeling refreshed and energized.
First and Second Stages: Light Sleep
You always start at stage 1 of the sleep cycle no matter how tired you are. Your eye movements will start to slow down, but your body will still be somewhat alert; it’s very easy for outside stimuli to wake you up at this point. You’ll only remain in this stage for a few minutes before moving on to stage 2.
Once stage 2 begins, your brain will start producing sleep spindles, which are a special kind of brainwave. They are believed to help mediate a variety of sleep-related functions, such as consolidating memory; they might also help protect the body from early awakenings. Stage 2 is one of the longest stages, taking up nearly half the cycle and lasting anywhere between 30 to 60 minutes.
Third and Fourth Stages: Deep and REM Sleep
Stage 3 is also called deep sleep. It’s much harder to wake you up once you’ve reached this point. During deep sleep, the body will start repairing damaged muscles and tissues. Cytokines will be produced to keep the immune system functioning properly and restore the energy level of cells. This stage is especially important for children and teenagers who are still growing and developing.
The fourth and final stage is known as REM sleep. As you likely know, REM stands for “rapid-eye movement” in reference to how the eyes start to make quick, jerky movements in every direction. As your heart rate and blood pressure start to rise, your brain will be consolidating new information learned during the day so that it’s committed to long-term memory.
Why are These Stages Important?
Your body needs to go through the sleep cycle multiple times every night. However, if you don’t get enough sleep, or if you have a disorder such as sleep apnea that keeps interrupting your rest, then you won’t spend enough time in stages 3 and 4. Your overall health will suffer, and you’ll feel drowsy and irritable during the day.
How much rest are you getting every night? Make sure you’re going to bed early enough to get at least 7 hours of sleep. If you think sleep apnea is waking you up during the night, see a sleep professional as soon as possible. Finishing the sleep cycle is crucial if you want to operate at your best during the day!
