iRest Yoga Nidra

iRest Yoga Nidra, short for Integrative Restoration, is a guided meditation based on the traditional yoga practice of yoga nidra, often called yogic sleep. It was developed by the American psychologist Richard Miller and is taught as a standard ten-step protocol. You lie or sit comfortably while a teacher guides your attention through steps that include setting an intention, sensing the body and breath, and welcoming whatever feelings, thoughts, and sensations arise without trying to change them.

Unlike traditional yoga nidra, iRest is presented in secular language and a fixed structure, which makes it easier to teach, study, and use in group settings such as clinics, veteran programs, schools, and workplaces. Sessions typically last 20 to 45 minutes, and the practice can also be done with a recording at home. Teachers train and certify through the iRest Institute, the organization Miller founded, so the method is more consistent than many meditation styles.

Research is growing but still early. Published studies include small pilot and feasibility trials with combat veterans, women who experienced sexual trauma, older adults with low mood, college students, health care workers, and people with persistent pain. Most are small, many lack a control group, and results are encouraging but not conclusive. In veteran and military programs it is offered with the aim of easing PTSD-related distress, and it may help some people feel calmer, though research is early. iRest is best understood as a structured relaxation and awareness practice. It is generally low risk, and it is not a substitute for trauma therapy or medical care.

Yoga nidra is an old yoga practice of guided deep relaxation, and its modern forms were popularized in the twentieth century. Richard Miller, born in 1948, is an American clinical psychologist and yoga teacher who first encountered yoga nidra in 1970. He studied with teachers including T. K. V. Desikachar and Jean Klein, co-founded the International Association of Yoga Therapists, and wrote The Theory and Practice of Yoga Nidra in 1985 and Yoga Nidra: A Meditative Practice for Deep Relaxation and Healing, published by Sounds True in 2005.

In the mid 2000s Miller adapted the practice for a US Department of Defense study of soldiers returning from Iraq and Afghanistan, working with Walter Reed Army Medical Center, and the resulting standardized, secular protocol became known as Integrative Restoration, or iRest. Accounts differ on the exact start date, so it is given here only as the mid 2000s. Miller founded the Integrative Restoration Institute, also called the iRest Institute, which trains and certifies teachers, and published The iRest Program for Healing PTSD in 2015. iRest is now offered in a range of settings, including some military and VA programs, but being offered is not the same as being proven. The research that exists is early, and Miller is a co-author on some of it.
