Sleep—The Unsung Hero of Performance
As busy men, whether you’re closing deals in the boardroom, training for a marathon, or balancing family life, you demand high performance from your mind and body every day. You track your steps, your macros, and your investments. But are you tracking the most powerful recovery tool you own? Sleep.
Specifically, we’re talking about REM (Rapid Eye Movement) sleep. This often-overlooked phase isn’t just about dreaming; it’s a vital, non-negotiable process that determines your next-day focus, your emotional stability, and your ability to heal and grow muscle. If you want to outperform your competition and maintain vitality well into your later years, you need to treat REM sleep like the critical performance metric it is.
The Four Stages of Sleep: Where REM Fits In
During a typical night (ideally 7–9 hours), your brain cycles through four distinct stages. These stages are divided into two main categories:
- NREM (Non-Rapid Eye Movement) Sleep: This includes three stages (N1, N2, N3). N3 is Deep Sleep, the physical repair phase where your body releases Human Growth Hormone (HGH) to repair muscle tissue.
- REM Sleep (The Mental Stage): Usually occurring in cycles roughly every 90 minutes, REM sleep is fundamentally different.
During REM, your brain activity, measured by an EEG, looks almost identical to when you are wide awake. Your heart rate and breathing increase, and your eyes dart rapidly behind closed lids (hence the name).
What Happens During REM Sleep?
Think of REM sleep as the brain’s operating system update:
- Memory Consolidation: Your brain actively processes and archives the information you took in during the day, moving it from short-term holding areas to long-term storage.
- Emotional Regulation: This is the phase where the brain processes emotional events and stressors. It helps “dull the sharp edges” of trauma or stress, leaving you less reactive and more resilient the next day.
REM’s Benefits: Fueling Focus, Mood, and Skill Acquisition
Sacrificing REM sleep doesn’t just make you tired; it directly impairs the functions critical for executives, athletes, and busy professionals.
- Peak Focus and Problem-Solving: REM sleep is directly linked to creativity and cognitive flexibility. Studies published on PubMed show that a lack of REM sleep severely hampers your ability to learn new skills and find novel solutions to complex problems. For the executive, this means sharper decision-making and innovation.
- Motor Skill Mastery: For athletes, REM sleep is where “muscle memory” is cemented. Whether you’re practicing a golf swing, a free throw, or a complex piano piece, the brain rehearsal happens in REM. Better REM means faster skill acquisition.
- Mental Resilience and Emotional Control: Poor REM sleep leaves the amygdala (the brain’s fear and stress center) hyper-reactive. Getting sufficient REM is key to waking up feeling less anxious, more stable, and ready to handle pressure.
Optimize Your Sleep Cycles: Tips for Boosting REM
REM sleep cycles lengthen as the night progresses. This means the last hour or two of an 8-hour night are the most REM-rich. Cutting your sleep short from 8 hours to 6 hours disproportionately reduces your REM time.
Actionable Strategies for Maximizing REM:
Pillar
Strategy
Why It Works
Consistency
Maintain a strict, non-negotiable bedtime and wake-up time (even weekends).
Your brain thrives on routine. Consistency trains your circadian rhythm to optimize sleep cycles.
Temperature
Keep your bedroom cool (ideally 60–67°F or 15–19°C).
A drop in core body temperature is necessary to initiate and maintain the deep stages of sleep, including REM.
Pre-Sleep Routine
Avoid alcohol and caffeine close to bedtime (4-6 hours).
Alcohol significantly fragments REM sleep, and caffeine is a stimulant that prevents the necessary calming of the brain.
Exercise Timing
Finish intense workouts at least 3 hours before bed.
While exercise helps sleep overall, an elevated core temperature too close to bedtime can make falling asleep and cycling through REM difficult.
Conclusion: Track the Right Metric
You wouldn’t expect a high-performance engine to run on fumes. Don’t expect your mind and body to perform at their best while consistently sacrificing the repair and update cycle of REM sleep.
Prioritizing a full 7 to 9 hours of quality sleep, and implementing strategies to deepen your cycles, isn’t laziness—it’s the most powerful, science-backed longevity and performance hack available.
FAQs
How much REM sleep should I aim for each night?
REM sleep typically accounts for about 20–25% of your total sleep time. For an 8-hour night, this is roughly 90 to 120 minutes of REM. Focus less on a precise number and more on ensuring you get a full 7-9 hours of total sleep, as your body will naturally optimize the REM ratio.
Does dreaming only happen during REM sleep?
While the most vivid, story-like dreaming occurs during REM sleep, some dreaming can also happen during the NREM stages (specifically N2 and N3), though it is generally less intense and less easily recalled.
I track my sleep, but my REM is low. What's the fastest fix?
The most common culprit is alcohol consumption and poor sleep consistency. Eliminate alcohol entirely 4–6 hours before bed, ensure your bedroom is completely dark and cool, and focus on locking down a consistent bedtime/wake time, as this helps your body cycle more efficiently.
Is Deep Sleep or REM Sleep more important for performance?
Both are equally critical but serve different functions. Deep Sleep (N3) is for physical recovery, tissue repair, and immune function. REM Sleep is for mental recovery, emotional regulation, and memory/skill consolidation. You need a healthy balance of both for peak overall performance.
