Sophia Deep Rest Session
Non-Sleep Deep Rest (NSDR), a term coined by Dr. Andrew Huberman, encompasses practices like Yoga Nidra and self-hypnosis. It involves guiding your brain into states of deep relaxation (theta and delta wave states) while remaining awake. It's a powerful tool to replenish energy, improve focus, and reduce stress in just 10-20 minutes.
