Yoga Nidra / Non-Sleep Deep Rest (NSDR)
10-30 min guided body-scan practice while lying still. Induces deep rest state that boosts dopamine by 65% (Kjaer et al., 2002), reduces cortisol, and can partially offset sleep debt.
Dosage & Timing
Evidence Strength
3/5 — ModerateModerate evidence. Kjaer et al. (2002) PET study showed 65% increase in endogenous dopamine during Yoga Nidra. Multiple studies show reduced anxiety and cortisol. Andrew Huberman has popularized NSDR as a practical recovery tool.
Overview
Practice a 10-30 minute guided Yoga Nidra or NSDR (Non-Sleep Deep Rest) session. Lie still with eyes closed while following body-scan and breathing instructions. This practice induces a state between wakefulness and sleep that accelerates dopamine replenishment, reduces cortisol, and can partially compensate for lost sleep.
How To Do It
Find a guided session
Search 'NSDR' or 'Yoga Nidra' on YouTube. Huberman's 10-min NSDR is a good starting point. Choose 10-30 min based on available time.
Lie down comfortably
Lie on your back with arms at sides. Close your eyes. Use a blanket if you tend to get cold.
Follow the instructions
The guide will walk you through body scanning, breath awareness, and intention setting. Don't try to stay 'alert' — drifting is fine.
Use strategically
Best used: after poor sleep, during afternoon energy dips, before demanding cognitive work, or to manage acute stress.
The Evidence
Each claim is linked to its source study. Confidence reflects the study design — systematic reviews and RCTs rank highest.
Meditation and yoga can modulate brain mechanisms that affect behavior and anxiety↗
Meditative relaxation practices affect stress, attention, and autonomic regulation pathways.

Related Protocols
Nature Exposure (Forest Bathing)
20+ min in nature 2-5x/week. Studies show nature exposure reduces cortisol by 12-28%, lowers blood pressure, and boosts natural killer cell activity for up to 7 days.
Expressive Writing for Stress
Write freely for 15-20 min about stressful experiences. Pennebaker's method (300+ studies) reduces cortisol, improves immune markers, and decreases doctor visits by 43%.
Post-Work Decompression
Create a 10-minute transition ritual between work and home mode to reduce carryover stress.
Physiological Sigh
Double inhale (nose) + long exhale (mouth). The fastest evidence-based technique to reduce acute stress — works in 1-3 breaths by activating the parasympathetic nervous system.
