Feeling tired doesn't always mean you need more caffeine or more sleep. Sometimes, your brain simply needs a chance to switch gears. That's the idea behind non-sleep deep rest (NSDR), a guided practice that takes your brain and body towards the edge of sleep without requiring you to actually drift off.
Popularised by Stanford neuroscientist Andrew Huberman, NSDR involves lying down and following a guided recording through slower breathing and a body scan. Sessions can last as little as 10 minutes and can be used after a poor night's sleep, during the afternoon slump or whenever your mind feels too switched on to properly rest.
To explain what actually happens during an NSDR session, we spoke to Kelly Boys, a mindfulness trainer, coach and NSDR specialist, whose protocols are recommended by Huberman.
"You're self-directing relaxation, bringing your body and mind into the transition point between wake and sleep," says Boys. "You're training your nervous system to enter a downstate, as Dr. Sara Mednick calls it, which can boost creativity and reset your energy. You can fall asleep or remain awake, it works either way."
You don't need any previous experience or specialist equipment. Just a guided recording, somewhere comfortable and 10 uninterrupted minutes.
Start with a 10-minute NSDR or Yoga Nidra recording led by an experienced teacher. Their voice will guide your breathing and move your attention around the body, so there's nothing to remember or get right.
The right voice makes more difference than you might think. Find one you enjoy listening to, with a pace that helps you slow down rather than rush through the session. Huberman recommends Boys' recordings and even includes them in his own daily NSDR practice. You can listen to her guided sessions here.
Lie on your back somewhere you can fully relax. A bed, sofa, yoga mat, or carpeted floor all work well. If your lower back feels uncomfortable, place a pillow beneath your knees. If lying down isn't practical, a reclining chair works too. The aim is to stop holding yourself up so your body can fully relax.
Think of this as giving your brain fewer things to process. Dim the lights, silence notifications, and close your eyes before you begin.
An eye mask can make daytime sessions feel more immersive, while headphones can help you stay with the recording. You may also want a blanket nearby, as it's common to feel cooler once your body settles.
Most recordings begin with your breathing before gradually moving your attention through different parts of the body. Your mind will wander, which is completely normal. Each time you notice it has drifted, bring your attention back to the next instruction without worrying about what you missed.
Boys describes the experience as "taking your mind on a walk through your body". "Focusing your cognition onto your physiology gives your mind a job," she explains. "Combining that with deep breathing helps you relax."
The biggest mistake, says Boys, is expecting a particular outcome. "There's no correct way to do it," she says. "It's about letting go and seeing what happens, not about managing or controlling your experience."
Some sessions will leave you feeling deeply relaxed. Others may feel restless or dreamlike. You might lose track of the recording or stay aware from beginning to end. It’s all part of the experience.
You don't have to stay awake for NSDR to be worthwhile. If you drift off, let it happen. If you're fitting a session into your working day, set a gentle alarm before you begin. If you're using NSDR before bed, let the recording carry on as you fall asleep.
Once the session ends, give yourself a minute before jumping back into emails, Slack messages, or social media. A slower return helps you hold onto that feeling of calm a little longer.
Ten minutes is enough for a beginner. Boys recommends trying it between activities, and allowing the stillness itself to do some of the work.
Here’s a simple guide:
There’s no established optimal duration. Direct NSDR research remains limited, although researchers have begun studying sessions as short as 10 minutes. Choose a length you can repeat. A short recording you use regularly is likely to be more useful than a longer one you keep putting off.
There's no single best time to practise NSDR. It works whenever you need to step away from mental noise, reset your focus, or give your nervous system a chance to slow down.
Energy naturally dips during the early afternoon. Ten to 20 minutes of NSDR can give your brain a break without reaching for another coffee or risking the grogginess that sometimes follows a nap.
"Afternoons are great for NSDR," says Boys. "You can use it when you need it." Rather than waiting until you're completely running on empty, try it as soon as you notice your focus or energy beginning to fade.
NSDR can't replace sleep, but it may help you feel calmer and more refreshed when a nap isn't an option. "After a poor night's sleep, you may be able to rest quietly and recover some of that sleep loss," says Boys.
If poor sleep has become your normal, it's worth speaking to your GP or a sleep specialist to understand what's behind it.
Working from home has blurred the line between work and everything else. A 10-minute NSDR session can create a clear pause between your final meeting and the rest of your evening. Boys recommends starting with 10 minutes after work. It's a simple habit that's much easier to stick to than waiting until you have a completely free evening.
Stress doesn't disappear the moment the stressful thing is over. It often lingers in your body, showing up as a tight jaw, shallow breathing or a mind that won't stop racing.
Closing your eyes, slowing your breathing and following a body scan can help shift you out of that state. "When you're stressed, it's the perfect reset of your emotions and your physiology," says Boys.
If your brain becomes busiest the moment your head hits the pillow, NSDR gives it something else to focus on. Following a guided recording can be easier than trying to force yourself to switch off while replaying conversations, planning tomorrow or watching the clock.
Choose a longer recording without adverts or an abrupt ending and let yourself drift off if sleep comes naturally.
Closing your eyes gives your brain less information to process. Lying still removes much of the physical effort involved in moving or sitting upright. The recording then narrows your attention to your breath and physical sensations.
Together, these conditions can move the body away from high alert and towards what sleep researcher Dr. Sara Mednick calls a ‘downstate’. Your brain remains active, and you may hear every word, experience dreamlike images, or move between awareness and drowsiness.
Research into Yoga Nidra has reported changes in sleep and cognitive performance, although studies are generally small and use different protocols. A 2023 study found improvements in objective sleep measures and cognitive processing after two weeks of daytime Yoga Nidra.
An earlier brain-imaging study recorded increased dopamine release during Yoga Nidra. This finding is sometimes used to claim that NSDR replenishes dopamine, but the research involved a small group of experienced practitioners. It cannot tell us that every brief session produces the same response.
Research into NSDR itself is still developing, but evidence from Yoga Nidra and related practices points towards a few possible uses:
A guided body scan replaces decision-making with a steady set of instructions. For a short period, there is nothing to plan, answer, or solve. This may make it easier to return to work without carrying the previous task around in your head.
Moving your awareness through the body can reveal how much tension you are holding in your forehead, jaw, shoulders, or hands. You don’t need to force those muscles to relax. Noticing the effort can be enough for some of it to ease.
One study involving people with chronic insomnia reported improvements when Yoga Nidra was added to their usual care. Boys says people who practise consistently may sleep better, feel more refreshed, and become less reactive.
NSDR may help when racing thoughts make it difficult to settle, but it’s not a treatment for every sleep problem. Conditions such as sleep apnoea, restless leg, and chronic pain need specific care.
NSDR doesn’t create energy or replace sleep. It removes noise, screens, and decisions for a few minutes. Afterwards, you may find it easier to begin the next task or realise that you didn’t need another coffee after all.
Good ideas have a habit of appearing in the shower, on a walk or just before sleep, when the brain is no longer pushing through the same line of thought. NSDR creates a similar pause. As the mind becomes less tightly focused, unexpected connections may surface.
Research into deep rest, memory, and creativity is still emerging, so we’re not saying this is a guaranteed productivity hack.
NSDR borrows heavily from Yoga Nidra, but the terms have different origins. NSDR is a modern umbrella term for guided practices designed to create deep rest. Yoga Nidra is a traditional Indian practice with a broader focus that can include intention, visualisation and self-inquiry.
“Yoga Nidra is the traditional practice that emerged from India and covers a wider range of practices intended for healing your psyche and helping you connect with your deeper intentions,” says Boys.
An NSDR recording is more likely to use secular language centred on breath and body awareness. To a beginner, the two may feel very similar.
NSDR uses techniques found in meditation, including awareness of breath, sensation and wandering thoughts. The experience is usually easier to follow because you’re lying down and listening to continuous instructions. There’s no expectation to sit upright, remain fully alert or clear your mind. That makes it a useful entry point for anyone who finds silent meditation frustrating.
A nap involves entering sleep. During NSDR, you may remain awake, become drowsy, or briefly drift off. A nap may make more sense when you’re sleep-deprived and can fall asleep easily. NSDR may suit you better when:
There’s not enough research directly comparing the two to claim that NSDR offers the same recovery as sleep. It’s better viewed as another way to rest when napping isn’t possible or doesn’t work for you.
A 45-minute recording can make rest feel like another task. Begin with 10 minutes.
Monitoring your breathing, relaxation, or mental state keeps you in performance mode. Follow the voice and let the session unfold.
Drifting off isn’t a failure. Use an alarm when you have limited time.
NSDR may make a tired day easier, but it can’t erase ongoing sleep deprivation or an untreated sleep disorder.
Give yourself a minute before returning to bright light, messages and notifications.
If you're not sure where to start, give this a go:
A guided recording is easier for your first sessions because you don’t need to watch the clock or remember the sequence.
The research behind NSDR is still evolving, but the practice itself is remarkably simple. Set aside 10 minutes, follow a guided recording and give yourself permission to do a little less. You don't have to stay awake. You don't have to clear your mind. You don't even have to feel relaxed every time.
Perhaps that's why NSDR has struck a chord. In a culture that turns almost everything into something to optimise, it asks you to stop trying quite so hard. Sometimes, that may be exactly what your brain has been asking for.
NSDR stands for non-sleep deep rest. Neuroscientist Andrew Huberman coined the term to describe guided practices that create deep relaxation without requiring sleep.
There’s no set schedule. Start with 10 minutes, two or three times a week, using the same recording until the process feels familiar.
Yes. You can remain awake, drift in and out, or fall asleep completely.
It may help you feel more rested after a poor night, but it cannot reproduce every function of sleep. Use it alongside an earlier night or another chance to recover.
Early NSDR research and a wider body of Yoga Nidra research suggest possible benefits for relaxation, sleep, and cognitive performance. Larger studies are needed before stronger claims can be made.
