What is NSDR and is it the same as yoga nidra?

NSDR (Non-Sleep Deep Rest) is a term popularized by neuroscientist Andrew Huberman. It’s essentially modern yoga nidra with some specific breath protocols added. The core mechanism is the same — systematic relaxation in the hypnagogic state between waking and sleeping. Huberman rebranded it to make the practice more accessible to people skeptical of traditional yogic terminology. StillMind offers both traditional yoga nidra and NSDR-style protocols.
