The better we understand our sleep, the better we can optimize it. In this series, we’re diving into the components of sleep to help you build a foundation for improving daily performance. This post will explore what REM sleep is, why it’s important, and how to get more of it.
What is REM Sleep?
REM (Rapid Eye Movement) sleep is a vital part of the sleep cycle, playing a crucial role in both mental and physical health—especially for athletes. During REM sleep, which typically makes up about 25% of the sleep cycle, the body experiences fast, random eye movements, increased brain activity, and a temporary inhibition of muscle tone. This is also the stage where most dreams occur.

Key Functions of REM Sleep
Memory Consolidation
One of the primary functions of REM sleep is memory consolidation. During REM, the brain processes and organizes information from the day, storing it in long-term memory. This is particularly important for athletes who need to retain strategies, plays, and techniques for competition.

Emotional Regulation
REM sleep also plays a significant role in emotional regulation. During this stage, the brain processes and stabilizes emotions, which is essential for maintaining a positive mindset and reducing the risk of burnout. Athletes, in particular, benefit from this as it helps them manage stress and stay focused.
Cognitive Function
REM sleep is crucial for enhancing cognitive abilities like problem-solving and decision-making. For athletes, who often need to make quick decisions under pressure, REM sleep supports this ability by allowing the brain to process complex information more efficiently.

Physical Health and Hormone Regulation
In addition to mental benefits, REM sleep supports physical health by regulating hormones, aiding muscle recovery, and boosting immune function. This is vital for athletes who need to perform at their peak and recover from intense training sessions.

Consequences of Insufficient REM Sleep
Lack of REM sleep can lead to:
- Impaired memory
- Emotional instability
- Decreased cognitive function
- Reduced physical health and immune strength
These factors can negatively impact daily performance, focus, and resilience, highlighting the importance of prioritizing REM sleep.
How to Maximize REM Sleep
1. Establish a Consistent Sleep Schedule
Setting a regular bedtime and wake-up time helps regulate your body’s internal clock, which promotes better REM sleep. Consistency is especially crucial for athletes, as it supports recovery and performance.
Dr. Michael Breus, a clinical psychologist and sleep expert, notes, “For athletes, a consistent sleep schedule is essential for balancing the body and supporting recovery from intense training.”
2. Create a Conducive Sleep Environment
A comfortable sleep environment promotes REM sleep. Keep your room dark, quiet, and cool, and invest in comfortable bedding and pillows to enhance sleep quality.

3. Practice Healthy Sleep Habits
Establish habits that promote REM sleep, such as:
- Avoiding stimulating activities before bed (like phone usage)
- Limiting caffeine, alcohol, and large meals several hours before sleep
These adjustments help reduce sleep disruptions, allowing your body to maximize time in REM.
Prioritize Sleep for Optimal Performance
To perform at your best, prioritize sleep as part of your daily routine. Elite endurance athlete and four-time Ironman World Champion Chrissie Wellington emphasizes, “Sleep is key to recovery and performance. I make sure to get at least 8 hours each night and prioritize my sleep schedule to optimize my REM sleep and training.”
Conclusion
REM sleep is a foundational part of the sleep cycle, essential for memory consolidation, emotional regulation, cognitive function, and overall well-being. By making an effort to improve your REM sleep through a consistent sleep schedule, a conducive sleep environment, and healthy sleep habits, you can boost daily performance and overall health.
Remember, sleep is just as important as exercise, work, and other daily activities. So, prioritize your rest and set yourself up for success!
