How to catch up on sleep as an athlete (Does NSDR work?)
Reading Time: 5 minsWe’ve all been there. It’s 3:00 AM, your alarm is set for 6:00 AM for an early morning training session, and you are staring at the ceiling, calculating exactly how many hours of sleep you’ll get if you drift off right this second.
You do the math. It’s not looking good.
As an athlete, your relationship with sleep is pretty intense.
You don’t just sleep to avoid looking like a zombie at breakfast; you sleep because your muscles are literally begging for reconstruction.
Yet, between travel schedules, late-night competitions, pre-race jitters, and early training blocks, athletes are notoriously sleep-deprived.
So, what do you do when you’re running on empty?
Can you actually "catch up" on sleep? And what is this "NSDR" (Non-Sleep Deep Rest) thing that tech gurus and neuroscientists keep raving about?
Let’s dive into the science of sleep recovery and see if you can hack your way back to peak performance.
The Myth and Reality of "Sleep Debt"
Let’s address the elephant in the bedroom: Can you actually catch up on missed sleep?
Yes and no. If you pull an all-nighter, sleeping for 12 hours the next night doesn’t completely erase the biological damage, but it does help your brain and body recover a significant portion of their cognitive and physical function.
When you sleep, your body undergoes massive repairs.
Your brain clears out metabolic waste through the glymphatic system, while your endocrine system floods your bloodstream with growth hormone to repair micro-tears in your muscle fibres.
If you cut this process short, you accumulate what researchers call sleep debt.
According to clinical studies on athletic performance, even moderate sleep deprivation—defined as getting less than 7 hours of sleep per night for a few consecutive days—can lead to:
A 30% reduction in time-to-exhaustion during cardiovascular training.
Impaired glycogen synthesis, meaning your muscles cannot store fuel as efficiently.
Slower reaction times, compromised spatial awareness, and impaired decision-making.
Increased levels of cortisol (the stress hormone), which actively hinders muscle recovery and promotes fat storage.
While you cannot simply sleep away 20 hours of accumulated sleep debt in a single weekend, you can systematically pay it back.
The most effective way is sleep extension—adding an extra 1 to 2 hours of sleep per night over a week.
Research on collegiate basketball players showed that extending sleep to 10 hours per night significantly improved shooting accuracy, sprint times, and overall mood.
But what if you do not have the luxury of sleeping 10 hours a day?
What if you are in the middle of a heavy training cycle, holding down a job, and need to recover right now?
Enter NSDR: What on Earth Is It?
If you’ve spent any time listening to health or performance podcasts recently, you’ve likely heard the term NSDR, or Non-Sleep Deep Rest.
Coined by Stanford neuroscientist Dr Andrew Huberman, NSDR is an umbrella term for practices that guide your brain and body into a state of deep relaxation without actually falling asleep.
The most common forms of NSDR are:
Yoga Nidra: An ancient yogic practice (literally meaning "yogic sleep") where you lie down and follow a guided meditation that takes you through systematic body scans and breathwork.
Hypnotherapy and Guided Relaxation: Structured breathing and visualization practices designed to calm the autonomic nervous system.
Instead of trying to force a 20-minute power nap—which often leaves you feeling groggier than before due to "sleep inertia"—NSDR keeps you right on the boundary between wakefulness and sleep, allowing the nervous system to rest without dipping into a full sleep cycle.
How NSDR Rewires Your Brainwaves for Recovery
To understand why NSDR is a game-changer for athletes, we have to look at brainwave states. When you are awake, alert, and training, your brain is firing in Beta waves (fast, active, and analytical).
When you begin to relax and wind down, you transition into Alpha waves.
During an NSDR session, your brain drops down into Theta waves (the state of deep relaxation, dreaming, and high suggestibility) and sometimes even touches Delta waves (the ultra-deep state associated with physical healing and deep, slow-wave sleep).
This shift triggers two major physiological benefits for athletes:
1. Dopamine Replenishment
A landmark study using PET scans showed that Yoga Nidra (the foundational practice of NSDR) can increase dopamine levels in the brain's striatum by up to 65%.
Dopamine is the neurotransmitter responsible for motivation, motor control, and focus—all of which are severely depleted when you are sleep-deprived. By replenishing these levels, you combat mental fatigue and restore your drive to train.
2. Parasympathetic Shift
NSDR acts as an off-switch for your sympathetic nervous system ("fight or flight") and rapidly activates your parasympathetic nervous system ("rest and digest").
This lowers your heart rate, increases heart rate variability (HRV), and signals to your muscles that it is safe to start repairing tissue.
How to Use NSDR in Your Training Routine
If you want to integrate NSDR into your schedule, you do not need fancy equipment.
You just need a quiet place to lie down, a set of headphones, and 10 to 30 minutes of undisturbed time.
1. Find your space: 1-2 mins.
Lie down flat on your back in a quiet, comfortable space. Use a yoga mat or lie on your bed.
If you are sensitive to light, put an eye mask or a light towel over your eyes to block out distractions.
2. Plug in and press play: 10-30 mins.
Put in your headphones and play a guided NSDR or Yoga Nidra track.
Keep your body completely still throughout the session.
3. Follow the breath: Throughout.
The guide will direct you through specific breathing patterns, such as double-inhales followed by long, slow, extended exhales.
This physically triggers your vagus nerve to slow down your heart rate.
4.Transition back gently: 2 mins.
Once the session ends, do not jump straight up. Wiggle your fingers and toes, take a deep breath, and slowly sit up.
You should feel calm, clear-headed, and ready to go.
Strategic Timing for Athletes
To get the most out of NSDR, you should align it with your specific recovery needs:
The "I Couldn't Sleep" Rescue: If you slept poorly the night before, do a 20-to-30-minute NSDR session in the early afternoon (between 1:00 PM and 3:00 PM) to restore dopamine and mental clarity without disrupting your upcoming night's sleep.
Post-Workout Cooldown: Do a 10-to-15-minute session immediately after a brutal workout.
This transitions your body out of the high-stress, high-cortisol state of training and jumpstarts the physical recovery process.
Pre-Competition Jitters: If your mind is racing before a big race or game and you cannot rest, a short NSDR session will calm your nervous system and lower your heart rate without making you feel sluggish or heavy.
The Verdict: Can You Catch Up on Sleep with NSDR?
Let's be completely clear: NSDR is not a perfect 1:1 replacement for night-time sleep.
You cannot live on four hours of sleep a night and expect a quick afternoon NSDR session to save you.
Deep, slow-wave sleep and REM sleep are absolutely vital for hormone production, immune function, and cellular repair, and nothing can fully replace them.
However, as a supplementary tool in an athlete's recovery toolkit, NSDR is incredibly effective.
It acts as a quick-reset button for your central nervous system, allowing you to claw back cognitive focus, calm physical tension, and accelerate your recovery when a full night's sleep simply wasn't on the cards.
So, the next time you find yourself staring at the bedroom ceiling at 3:00 AM, do not panic.
Control what you can. Do your best to rest, and keep a 20-minute NSDR track ready in your headphones for the next afternoon. Your muscles and your sanity will thank you.
Now go lie down, close your eyes, and let your brainwaves do the heavy lifting for once!
