The Role of Sleep Cycles in Maximizing Sleep Efficiency 

Every night, when you lay down to rest, your body goes through several stages of sleep that comprise the sleep cycle. While we might think that getting enough sleep is just about feeling energized in the morning, it’s so much more than that. With the average sleep cycle lasting about 90 minutes, there are many ways that our sleep cycles can maximize our sleep efficiency and even promote our overall well-being. 
 
In this article, we’ll explore the role of sleep cycles in maximizing sleep efficiency, uncovering how you can enjoy better energy and sleep quality, and even support your body’s daily need to rest and recover. We’ll also explore how completing your sleep cycle before waking promotes your well-being and helps you rest more effectively if you implement consistent sleep schedules. Let’s get into the first point: how your sleep cycle, when synchronized and uninterrupted, helps you enjoy better energy. 

Enjoy Better Energy with Cycle Synchronization

When you sync your life to your sleep cycle, you’ll not only get better rest but also wake up feeling much more rested. Your circadian rhythm guides your energy levels, but you also have to be mindful of allowing your entire sleep cycle to end. If you don’t sync your schedule to your sleep cycle, you could wake up drowsy, exhausted, and simply out of energy. 
 
For example, if you failed to get enough sleep the night before and had to wake up to head out to work, you likely woke up with a headache or felt the impact of what many researchers call partial sleep deprivation (SDN). However, if you find time to get to bed earlier or even take a 30-minute nap throughout the day, you can alleviate the challenges of drowsiness and poor energy and even encourage more energy!  
 
As you can tell, syncing your schedule with your sleep-wake cycle is essential if you want to experience the best energy possible. It’s also important to allow your body to optimize REM sleep so that you enjoy even better sleep quality.

REM Sleep Optimization Leads to Better Sleep Quality

You likely already know the importance of REM sleep, but studies have also shown that it can help you maximize your sleep efficiency by encouraging sleep continuity and helping your brain prepare for returning to consciousness and a wake state. One study focused on the use of artificial light during the night hours and how this impacted circadian rhythms and specifically REM sleep.  
 
What they discovered was truly astonishing: because REM sleep and the sleep-wake cycle are ruled by your circadian rhythm, disruptions to the circadian rhythm actually led to less-quality REM sleep. They also learned that REM sleep is critical for ensuring sleep quality and continuation, which is a hallmark of sleep quality and efficiency (Source: International Journal of Environmental Research and Public Health).  
 
Optimizing your REM sleep can lead to better sleep quality and even less likely disruptions throughout the night, which, as we have explored in other articles, helps with your performance both mentally and physically. However, let’s also explore how your sleep cycle, when allowed to be completed thoroughly, supports your body’s need for rest and recovery. 

Prioritized Deep Sleep Supports Your Body’s Rest

If you prioritize your body’s need for sleep, you will not only be able to complete your sleep cycle efficiently, but you’ll also encourage more deep sleep. Your deep sleep every single night—or even during naps—is necessary for your brain and body to be able to function. Without proper deep sleep, you will not be able to maintain your health or performance.  
 
It's true that your body spends hours every night coding and repairing your body, but did you know that your REM sleep or deep sleep is also associated with your body’s ability to rest and maintain immunity? To maximize your sleep efficiency, your sleep cycle takes this time during REM sleep to help your body prepare for waking with alertness while also regulating your body’s temperature and metabolism (Source: Sleep and Sleep Disorders).  
 
When you take care of yourself and allow your sleep cycle to complete every day, you’re prioritizing your body’s rest and recovery, but you’re also promoting your holistic wellness.

Completing Your Sleep Cycle Promotes Well-Being

Your sleep cycle helps you maximize your sleep efficiency, but it also encourages your holistic health, too. If you struggle with allowing your body to complete an entire cycle, you likely remember that horrible feeling that you got when you woke up! If you are not in sync with your sleep cycle and not making an effort to maximize your sleep efficiency, especially if you are a night shift worker, this could lead to challenges. 
 
Night shift workers, as compared to others, are more likely to struggle with poor sleep and feel misaligned, even struggling with poor mental health outcomes (Source: Nature). That’s where your sleep cycle comes in: not only does it help your sleep be the most efficient it can possibly be at helping your body’s health, but it also promotes your mood stability and your overall mental health.  
 
When your internal clock is on schedule and you enjoy full sleep schedules, you’ll notice a difference in your well-being, allowing you to rest more effectively than before so you always feel your best when you wake in the morning.

Improve Your Sleep Efficiency by Aligning with Your Sleep Cycle

If you prioritize taking care of your sleep cycle, you’ll not only improve your sleep efficiency, but you’ll elevate your health, too. Your sleep is the foundation of your health, so as long as you are getting adequate rest and not waking up too soon, or skipping sleep, you will notice a difference—not only physically, but also mentally!
