Most NSDR guides say "practice anytime." That's lazy advice. After digging into Huberman's research and testing protocols from yoga nidra experts, here are 4 timing windows that actually work for energy, sleep, and focus. For a complete overview of how NSDR works, see our guide to the science behind NSDR.
The Best Times to Practice NSDR (Quick Answer)
The best time depends on what you want from your practice. Here's the breakdown:
| Goal | Best Time | Duration | Why It Works |
|---|---|---|---|
| Reduce stress & anxiety | Morning (6-8am) | 10-15 min | Sets calm baseline before cortisol peaks |
| Boost energy & focus | Afternoon (1-4pm) | 10-20 min | Counters the natural "postprandial dip" |
| Improve memory & learning | After studying/practice | 10-20 min | Consolidates new information |
| Fall asleep faster | Bedtime | 30-60 min | Transitions directly into sleep |
Best for most people: Start with afternoon NSDR around 2-3pm. It targets the energy slump everyone experiences and provides the most noticeable immediate benefit.
If you're dealing with anxiety or racing thoughts, morning NSDR will have more impact on your overall day.
Morning NSDR: For Stress Reduction and Mental Clarity
Morning NSDR works because your cortisol levels are naturally rising. Adding a calm, intentional practice before the day's chaos hits creates a foundation that carries through.
Yoga nidra instructor Rosalie explains her approach:
“"If you're looking to reduce stress and anxiety, then I'd highly recommend practicing in the morning. Wake up, go to the loo, drink a glass of water and then lie back down and practice for 10 to 15 minutes. This is what I do every single morning, sometimes a little bit longer, and honestly it makes a massive difference to my day."

Morning NSDR Protocol
- Wake up naturally (no snooze)
- Use the bathroom, drink water
- Lie back down in a comfortable position
- Play a 10-15 minute NSDR audio
- Get up slowly, get morning light
Why it beats coffee: Caffeine blocks adenosine receptors, masking tiredness without clearing it. NSDR actually restores mental clarity. The difference becomes obvious around 2pm when the coffee crash hits and NSDR practitioners don't experience the same drop.
Choose morning NSDR if: You wake up with racing thoughts, feel anxious about your day, or want a sustainable alternative to caffeine dependency.
After Learning: For Memory Consolidation and Retention
This is the timing most people miss entirely.
NSDR practiced shortly after learning something new helps your brain consolidate that information. Dr. Wendy Suzuki's research at NYU found that a daily 13-minute NSDR practice led to increased attention, working memory, and recognition memory while reducing anxiety.
The mechanism involves theta waves, which increase during NSDR. These same waves are associated with learning and skill acquisition. For more on how NSDR affects your brain chemistry including the 65% dopamine increase, the science is fascinating. Practicing NSDR after a study session essentially gives your brain dedicated processing time.
When to Use Post-Learning NSDR
- After language study sessions
- After practicing a musical instrument
- Following a lecture or course module
- After learning a new software tool
- Post-workout (motor learning consolidation)
Duration: 10-20 minutes is enough. You're not trying to sleep. You're giving your brain space to encode what you just learned.
The research is clear: This timing works. But almost no one does it because they jump straight from learning into the next task. Building a 15-minute NSDR habit after focused learning sessions is one of the highest-leverage changes you can make.
Afternoon NSDR: For the 2-4pm Energy Dip
Here's the thing about afternoon fatigue: it's biological, not a character flaw.
Your body experiences a "postprandial dip" (fancy term for post-lunch slump) typically between 2-5pm. This happens regardless of what you ate. Your circadian rhythm includes a natural dip in alertness during this window.
Most people fight it with caffeine. That works short-term but disrupts sleep later, creating a cycle of poor rest and more caffeine.
NSDR offers an alternative that actually addresses the underlying fatigue.
“"If you're looking to boost your energy level or your productivity or maybe even your creativity... I'd recommend practicing when you start to notice that you need that little boost, maybe that 3pm slump."

Afternoon NSDR vs. Nap vs. Coffee
| Option | Time Required | Alertness After | Sleep Impact | Best For |
|---|---|---|---|---|
| NSDR | 10-20 min | Alert immediately | None | Most situations |
| Power nap | 20-30 min | Groggy 15-30 min | Minor if before 2pm | Sleep debt recovery |
| Coffee | Immediate | Alert 30 min later | Disrupts if after 2pm | Emergencies only |
Best choice for most people: NSDR. You get restored energy without grogginess and without disrupting tonight's sleep.
Choose a nap instead if: It's before 2pm, you're significantly sleep-deprived, and you have 30+ minutes including wake-up time.
Choose coffee if: You have an immediate, time-sensitive task and accept the tradeoff of potential sleep disruption.
Evening NSDR: For Better Sleep
Evening NSDR works differently than daytime sessions. Instead of trying to emerge alert, you're inviting the transition into sleep.
“"If you're looking to fall asleep quicker or to improve the quality of your sleep, then I'd suggest practicing in bed when you're ready for sleep. Just make sure that there's nothing at the end of the track that will wake you up and bring you back."

A 2023 study found that yoga nidra (the practice NSDR is based on) improved sleep efficiency by approximately 4% and reduced wake time during the night by 20 minutes. For people with insomnia or sleep difficulties, those numbers represent significant quality-of-life improvements. If you're looking to optimize your sleep further, our guide on how to increase deep sleep tonight covers additional strategies.
Evening NSDR Protocol
- Get into bed at your normal time
- Start a longer NSDR session (30-60 minutes)
- Use one designed for sleep (no wake-up cues at the end)
- Let yourself drift off during the practice
Duration matters here: Longer sessions work better for sleep. Dr. Andrew Huberman notes that 30-60 minute sessions are ideal when using NSDR specifically for sleep recovery or falling asleep.
Pro tip: If you wake in the middle of the night and can't fall back asleep after 20 minutes, NSDR is more effective than lying there frustrated. Put in earbuds and start a session.
NSDR vs. Napping: When to Choose Each
This decision confuses people. Here's the simple framework:
Choose NSDR When:
- It's after 2pm (naps this late disrupt nighttime sleep)
- You need alertness immediately after
- You only have 10-15 minutes
- You get groggy or grumpy from naps
- You have trouble sleeping at night
Choose Napping When:
- It's before 2pm
- You have significant sleep debt (less than 6 hours last night)
- You have 25-30+ minutes (including wake-up time)
- You handle post-nap grogginess well
- Your nighttime sleep isn't affected by daytime naps
The key difference: NSDR provides rest without entering actual sleep stages. You emerge alert. Naps involve real sleep, which includes sleep inertia (that groggy, disoriented feeling).
If you consistently feel worse after naps, stop napping and switch to NSDR entirely.
How Long Should Your NSDR Session Be?
Duration depends on your goal and available time:
| Duration | Best For | Expected Outcome |
|---|---|---|
| 10 minutes | Quick reset, afternoon energy | Mild restoration, reduced stress |
| 20 minutes | Standard daily practice | Full mental refresh, improved focus |
| 30 minutes | Deep restoration, sleep prep | Significant stress relief, transition to sleep |
| 60 minutes | Sleep recovery, dopamine restoration | Maximum restorative benefits |
Huberman's research notes that an hour-long NSDR session increased baseline dopamine levels in the brain by as much as 65%. That's a significant neurochemical shift from one practice session.
Start with 10 minutes. You can always extend later. A 10-minute session you actually do beats a 30-minute session you skip because it feels like too much time.
Best for building the habit: 10-minute afternoon sessions until it becomes automatic. Then experiment with longer durations or additional timing windows.
The Science: Why Timing Matters (Cortisol and Circadian Rhythms)
Understanding the "why" helps you customize timing to your schedule.
Your body runs on a roughly 24-hour cortisol cycle. Cortisol peaks in the morning (helping you wake up and feel alert) and drops in the evening (preparing you for sleep).
Dr. Andrew Huberman explains the cortisol rhythm:
“"You want high levels of cortisol upon waking and in the first hours after waking... your cortisol levels are very low in the evening, or they should be."
— Dr. Andrew Huberman, Tools to Set Your Cortisol Rhythm, 0:21-1:45
“
NSDR works with this rhythm:
- Morning NSDR: Doesn't suppress the healthy cortisol rise but addresses anxiety before the day starts
- Afternoon NSDR: Addresses the natural dip without caffeine that extends cortisol unnaturally
- Evening NSDR: Supports the natural cortisol decline that enables sleep
If you try to "push through" the afternoon dip with stimulants, you're fighting your biology. NSDR works with it.
Frequently Asked Questions
Can I do NSDR multiple times a day?
Yes. Huberman recommends one to three times per day. Quality matters more than quantity. One focused 20-minute session provides more benefit than three distracted 10-minute sessions.
What if I fall asleep during NSDR?
That's fine, especially for evening sessions. Your body needed sleep.
If you're doing afternoon NSDR and keep falling asleep, try sitting slightly reclined instead of lying flat, or shorten your session. Falling asleep during a daytime session usually signals sleep debt that needs addressing.
Is there a bad time to do NSDR?
No truly "bad" time exists. The practice works anytime.
That said, avoid starting a session right before something requiring immediate alertness (like a presentation in 15 minutes). Give yourself 5-10 minutes after NSDR to fully reorient.
How long before I notice benefits from consistent practice?
Some benefits are immediate. You'll feel calmer and more alert after your first session.
Cumulative benefits (improved memory, reduced baseline anxiety, better sleep architecture) appear after 8+ weeks of daily practice. The 13-minute daily protocol in Dr. Wendy Suzuki's research ran for 8 weeks before measuring cognitive improvements.
Does NSDR work if I can't "clear my mind"?
Yes. NSDR doesn't require a clear mind. The practice involves following audio cues about breathing and body awareness. Thoughts will arise. You notice them and return to the instructions.
If you're waiting until you can "clear your mind" to start, you'll never start. Begin now, thoughts and all.
