How long should a yoga nidra session be?

Traditional yoga nidra practice is 30-45 minutes. But research shows 10-20 minute sessions still produce measurable relaxation response. For beginners, 15-20 minutes is ideal — long enough to reach the theta brainwave state, short enough to stay engaged. For daytime energy recovery, even 10 minutes helps. StillMind adapts session length to your available time and experience level.
