Nidra Yoga

Yoga Nidra, also called Nidra yoga, is a guided practice of deep relaxation, often described as yogic sleep. You lie down and are led through a sequence that keeps the mind gently awake while the body rests, a state between waking and sleep. It needs no flexibility, strength, or yoga experience.

A session usually lasts from about 20 minutes to an hour, and shorter recordings are common. Lying comfortably, you follow a teacher's voice through steps such as setting an intention, noticing the breath, moving attention through the body, and visualizing images. No movement is needed, and drifting into sleep is fine.

People use it to unwind, ease stress and anxious thoughts, sleep better, and recover from tension and fatigue. Practitioners also describe it as supporting mood, focus, and a calmer relationship with pain, and some people use it as an accessible way into meditation.

The evidence is moderate and growing. Several randomized and observational studies have measured outcomes such as stress, anxiety, sleep quality, and blood pressure, and many report improvements. Many studies are small and short, and some lack strong control groups, so it is not yet clear how large the effects are or for whom it works best.

Yoga Nidra is generally gentle, but the deep relaxation and inward focus can bring up strong emotions for some people. If you have active psychosis, untreated bipolar disorder, a dissociative condition, or a history of trauma, check with a mental health professional first. It complements, not replaces, medical care, and a trained teacher can guide you safely.

The term yoga nidra appears in older Sanskrit literature, where it often describes a state of yogic sleep, and some tantric practices of body awareness and mental repetition influenced later teaching. The structured practice taught today was shaped by Swami Satyananda Saraswati (1923 to 2009), a disciple of Swami Sivananda of Rishikesh. He described a method of guided relaxation that moves attention through the body, and he set it out in his book Yoga Nidra, published by the Bihar School of Yoga in 1976.

Satyananda founded the Bihar School of Yoga in Munger, India, in 1963, and its teachers carried yoga nidra to centers in many countries. His protocol includes setting a short resolve, called a sankalpa, at the start and end of a session, and a rotation of awareness through body parts. Other lineages teach their own versions.

Yoga nidra later entered health and wellness settings. Richard Miller, a psychologist and yoga teacher, developed iRest, a secular adaptation based on Satyananda's approach, and it was used in programs for military personnel, including at Walter Reed Army Medical Center in the 2000s. Today yoga nidra is taught in yoga studios, hospitals, meditation centers and online. Training is mostly through yoga teacher programs and lineage-based courses, and there is no single credentialing body.
