Yoga Nidra—known as yogic sleep—is a meditation and conscious relaxation practice that is intended to induce total physical, mental, and emotional relaxation. I’ve heard that an hour of yoga nidra can be as restorative as four hours of regular sleep. Aside from being relaxing, restorative and restful, studies have shown that yoga nidra can also:
Ease insomnia
Decrease anxiety
Alleviate stress
Heighten awareness and focus
Transform negative habits, behaviors and ways of thinking
