NSDR: Reset Your Stress, Sleep & Hormones Without Sleeping
We live in a culture that celebrates doing more and resting less. But without recovery, the body and mind can’t function at their best. At FMU, we’re continually reminded that rest isn’t optional, it’s essential. That’s why this month, we’re highlighting NSDR (Non-Sleep Deep Rest), a simple, science-backed way to restore your health beyond sleep.
NSDR can be practiced almost anywhere — it’s about intentionally shifting into a state of deep rest.
Why NSDR Matters: Science‑Backed Recovery Beyond Sleep
Rest is essential for restoring both the body and mind. While sleep is critical for repair and memory, true recovery also requires intentional downtime throughout the day. These pauses, known as Non-Sleep Deep Rest (NSDR) are just as important for balancing stress hormones, strengthening immune function, and maintaining steady energy.
Rest vs. Sleep: How NSDR Complements Both
Sleep and rest serve different but complementary roles:
Sleep is a biologically driven process that happens while unconscious, repairing tissues, consolidating memories, and releasing key hormones like melatonin and growth hormone.
Rest — including NSDR practices like lying down with guided breath, mindfulness, or short relaxation breaks — is conscious. It allows the nervous system to reset, reducing stress, lowering cortisol, and creating space for recovery in real time.
Even short moments of NSDR during the day help shift the body out of high alert and back into balance. Over time, this strengthens resilience, improves sleep quality at night, and supports overall health.
NSDR & Hormone Balance: Regulating Cortisol and Melatonin for Restful Sleep
Your body’s circadian rhythm regulates hormones that affect mood, metabolism, and sleep. Cortisol — often called the “stress hormone” — naturally peaks in the morning to give energy, then tapers off through the day. Melatonin — the “sleep hormone” — rises in the evening to prepare the body for rest.
When stress is prolonged, cortisol can remain elevated. This imbalance makes it harder to fall asleep, disrupts recovery, and can contribute to fatigue, mood changes, and metabolic issues.
Practicing Non-Sleep Deep Rest (NSDR) during the day helps bring cortisol back to healthy baseline levels, creating the conditions for melatonin to rise naturally at night. The result is deeper, more restorative sleep.
Cortisol → Peaks with stress or busy activity; regulated through intentional rest.
Melatonin → Requires darkness and calm to be released; supported by NSDR practices.
NSDR & Immunity: How Deep Rest Strengthens Your Body’s Defenses
Even short pauses in your day — like sitting quietly outdoors — can support recovery and immune health through NSDR
The link between rest and immunity is well established. When you give the body time to recover, it can repair, regenerate, and strengthen defenses against illness. In contrast, chronic stress and lack of rest suppress immune activity, leaving you more vulnerable to infections — especially during colder months and high-stress seasons.
During stress or sleep deprivation, the body produces inflammatory cytokines — chemicals that weaken immunity when they remain elevated. By practicing Non-Sleep Deep Rest (NSDR), you help lower this inflammatory response, giving your immune system the capacity to do its job: fighting off viruses, healing injuries, and keeping you resilient.
How to Build Rest Into Your Daily Routine
Rest can feel impossible in busy seasons, yet it’s one of the most powerful tools for health. Even short, intentional pauses lower stress, improve sleep quality, and strengthen resilience.
One approach gaining recognition is Non-Sleep Deep Rest (NSDR) — deliberate states of calm that go beyond traditional sleep. NSDR can be practiced through guided meditation, yoga nidra, or mindful breathing exercises. These techniques activate the body’s relaxation response without requiring actual sleep, helping you recover even on restless nights.
What Is NSDR (Non-Sleep Deep Rest)? Benefits and How It Works
Non-Sleep Deep Rest (NSDR) refers to intentional states of deep relaxation that can be achieved while awake. Practices like guided meditation, yoga nidra, and mindful breathing activate the body’s natural relaxation response without requiring actual sleep.
Research shows that NSDR can:
Lower stress and cortisol levels
Improve focus and concentration
Support heart rate variability (HRV)
Enhance neuroplasticity — the brain’s ability to adapt and form new connections
Stanford neuroscientist Dr. Andrew Huberman has highlighted NSDR’s role in activating the parasympathetic nervous system (the body’s “rest and digest” mode). This shift allows the body to recover more efficiently, regulate stress, and restore balance.
NSDR Techniques: Simple Practices You Can Start Today
Adding NSDR (Non-Sleep Deep Rest) into your daily routine is a powerful way to restore calm and mental clarity. Even 10–20 minutes of a guided session can lower stress, regulate the nervous system, and support recovery.
How to Practice NSDR
Yoga Nidra: A guided meditation that leads you through different parts of the body, promoting deep relaxation without sleep. Studies show yoga nidra improves sleep quality, reduces anxiety, and enhances restfulness.
NSDR Protocols: Guided audio or video sessions (many freely available online) designed to create deep relaxation. Most last between 10 and 30 minutes.
Mindful Breathing: A simple, effective method is the 4-7-8 breathing technique. Inhale for 4 seconds, hold for 7 seconds, exhale for 8 seconds. This activates the parasympathetic nervous system, helping the body reset and relax.
Personal Note: I’ve been practicing 15 minutes of yoga nidra before bed. Even on nights with less sleep, I wake up feeling restored — as if I’ve caught up on hours of rest. It’s a powerful reset during busy times.
NSDR-Inspired Evening Routine for Deeper Sleep
An intentional evening routine prepares both body and brain for restorative sleep. By sending the right signals to your nervous system, you support melatonin production and set the stage for NSDR-inspired calm. These steps don’t need to be complicated — small, consistent habits can make a big difference.
Herbal teas like chamomile, lavender, or lemon balm can calm the nervous system and prepare you for deeper rest.
Tips for a Restful Evening Routine:
Turn Off Screens: Blue light from phones and computers disrupts melatonin, making it harder to fall asleep. Aim to shut down devices 30–60 minutes before bed.
Dim the Lights: Lower lighting in your home helps cue melatonin production and gently shifts the body toward rest.
Choose Calming Activities: Reading, journaling, or listening to soft music helps the mind release daily stress and enter a restful state.
Sip Warm Herbal Tea: Teas like chamomile, lavender, or lemon balm soothe the nervous system and prepare you for sleep.
Building simple rituals — like dimming the lights and sipping a calming tea — signals the body it’s safe to relax. Over time, these routines reinforce your natural rhythm, leading to deeper, more restorative sleep.
Midday NSDR: Simple Mindful Breaks to Reset Stress
Rest isn’t only for nighttime sleep. Short, intentional breaks during the day can help lower stress, reset your nervous system, and prevent burnout. Research shows that even a few minutes of mindful rest can reduce cortisol, improve clarity, and boost energy.
How to Take Midday NSDR Breaks:
Breathing Exercises: Just a few minutes of focused breathing lowers cortisol and calms the mind. The 4-7-8 technique (inhale for 4 seconds, hold for 7, exhale for 8) is a simple way to relax your nervous system.
Stretch or Move: A quick stretch, gentle walk, or body scan relieves tension, improves circulation, and restores focus.
Mindful Pause: Close your eyes for one minute, notice your breath, and let distractions go. Even brief mindfulness resets can significantly improve how calm and focused you feel.
Personal Note: Even five minutes of mindful breathing between appointments helps me reset my mind and release stress. These micro-breaks have become one of my most effective tools for resilience in daily life.
NSDR Movement Techniques: Gentle Practices for Relaxation & Recovery
The restorative pose ‘Legs Up the Wall’ calms the nervous system, reduces stress, and supports deep rest.
While intense workouts can be taxing, gentle movement actually promotes rest and recovery. Practices like stretching, yoga, or mindful walking help release tension and activate the parasympathetic nervous system — the “rest and digest” mode that supports deep healing.
Stretching: Light stretches before bed calm the nervous system, ease muscle tension, and make it easier to fall asleep.
Restorative Yoga: Poses like Legs Up the Wall or Child’s Pose soothe the body, encourage circulation, and reduce stress without overexertion.
Walking Meditation: Slow, mindful walking — especially outdoors — combines movement with breath awareness, creating a meditative reset for both mind and body.
Personal Note: My favorite restorative pose is Legs Up the Wall. Just a few minutes before bed helps release tension in my lower body and brings a deep sense of calm.
NSDR & Naps: How Short Rest Restores Energy & Focus
Naps can be a strategic way to restore energy and focus — especially if you’ve had a short night of sleep. Research shows that even brief naps can improve alertness, enhance memory, and lower stress levels. Combined with NSDR practices, naps become an even more effective tool for recovery.
How to Nap Effectively (NSDR Style):
Keep It Short: Aim for 10–20 minutes. Longer naps can cause sleep inertia (grogginess) while shorter naps provide a quick reset.
Time It Right: Early afternoon (around 1–3 p.m.) aligns with your body’s natural dip in energy.
Create a Calm Environment: A quiet, comfortable space with an eye mask or earplugs helps you fully relax without distraction.
Personal Note: On days after a restless night, a 15-minute nap restores my energy and clarity. Even a short rest makes the rest of the day feel more manageable.
Functional Medicine Insight: How NSDR Supports Hormone Balance
Hormones govern energy, mood, and metabolism — and rest plays a central role in keeping them balanced. When recovery is disrupted, key hormones like cortisol, melatonin, and insulin become dysregulated, leading to stress, fatigue, and metabolic challenges.
From a functional medicine perspective, NSDR is a valuable tool to restore equilibrium. By activating the parasympathetic nervous system and lowering stress signals, NSDR helps bring hormone levels back into alignment. Here’s how rest supports three of the body’s most important hormonal systems:

NSDR & Cortisol: Calming the Stress Hormone
Cortisol, the body’s primary stress hormone, follows a natural rhythm — rising in the morning to promote alertness and declining at night to support sleep. But chronic stress or lack of recovery keeps cortisol elevated, leading to fatigue, sleep issues, weight gain, and hormonal imbalances.
Practices like Non-Sleep Deep Rest (NSDR), deep breathing, and mindfulness help bring cortisol levels back to baseline. This supports energy stability, stress resilience, and overall hormone balance throughout the day.
NSDR & Melatonin: Supporting Sleep and Circadian Rhythms
Melatonin is released in response to darkness, signaling the body to prepare for sleep. Disrupted routines, evening screen time, or inconsistent rest can suppress melatonin, making it harder to fall asleep and affecting mood and recovery.
NSDR supports melatonin by calming the nervous system and promoting consistency in rest cycles. Pairing NSDR with habits like dim lighting, screen-free time, and calming evening rituals reinforces healthy circadian rhythms, improving sleep quality and mental clarity.
NSDR & Insulin: Restoring Metabolic Balance
Insulin allows the body to regulate blood sugar and maintain metabolic balance. Chronic stress, sleep deprivation, and high cortisol levels can drive insulin resistance — making it harder for cells to respond properly, which increases the risk of blood sugar imbalances and weight gain.
By reducing stress and supporting recovery, NSDR improves insulin sensitivity and helps maintain steady energy, healthy metabolism, and weight balance. Consistent rest patterns also strengthen the body’s ability to adapt, preventing long-term metabolic dysfunction.
