This is a guided 20-minute Yoga Nidra to help you sleep and relax. It contains the Schumann Resonance as a background sound as well as a deep meditation bell. The Schumann Resonance signal operates by being resonantly absorbed by brain systems and altering the serotonin/melatonin balance. Studies have shown people experience benefits like enhanced sleep, learning/memory, body rejuvenation, balance, improved stress tolerance, anti-jetlag, and grounding.
