Welcome to Yoga Nidra: An ancient, sleep-based guided mindfulness meditation practice that is now being used by corporate executives, military veterans, elementary school children, and the terminally ill. Many who have personally experienced Yoga Nidra tout its litany of benefits. And they are not the only ones: Neuroscientists are now proving that a single Yoga Nidra session can replace hours of sleep, and that regular practice can reverse anxiety, depression, PTS, chronic pain, and high blood pressure. The best part? The practice is available to anyone with 30 minutes and a comfortable place to lie down.
