Yoga Nidra for Sleep

What Is Yoga Nidra?

Yoga nidra is an ancient relaxation technique that involves being led through mental imagery while lying on one’s back. In yoga terms, this position is called shavasana or corpse pose. Although yoga nidra has ancient roots, it wasn’t introduced to the public until the 1960s. At that time, a yogi named Swami Satyananda Saraswati began publishing writings that clearly outlined steps involved in the yoga nidra practice. 

The phrase yoga nidra comes from the Sanskrit language and is often described as meaning “yogic sleep.” Yoga nidra is intended to produce a state of relaxation that is similar to sleep, but involves maintaining conscious awareness of the environment.

Scientific research confirms that yoga nidra can trigger what is called a hypnagogic state, Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

For this reason, researchers have suggested yoga nidra could help treat insomnia.

Yoga Nidra vs. Meditation

Yoga nidra and other forms of yoga typically involve aspects of meditation. Meditation is a practice of intentionally directing one’s attention in a specific way, or noticing things without passing judgment on them. 

Some researchers consider yoga nidra a form of guided meditation. Others, however, say yoga nidra differs from meditation in that it is practiced while lying down, not while sitting up. Yoga nidra also differs because it involves entering a sleep-like state, which does not always occur with meditation.

How Yoga Nidra Can Improve Sleep

Existing research suggests that yoga nidra may help people fall asleep faster and experience higher quality sleep.

Experts have suggested that yoga nidra may improve sleep by activating the parasympathetic nervous system Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

By reducing sympathetic and increasing parasympathetic nervous system activity, yoga nidra may relax the body and increase time spent in deep sleep.

Other Benefits of Yoga Nidra

In addition to improving sleep, researchers have suggested yoga nidra may provide additional benefits.

Yoga nidra likely improves stress and anxiety for the same reasons it improves sleep — by slowing the sympathetic nervous system and prompting the parasympathetic. Research measuring autonomic nervous system activity confirms that engaging in yoga nidra triggers a relaxation response through a shift from sympathetic to parasympathetic activity.

Improved Mood, Confidence, and Self-Esteem

One study found that regularly practicing yoga nidra improved mood, Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

Yoga nidra may improve a person’s confidence and self-esteem by reducing stress. Past studies have found that self-esteem and stress management are closely related. For example, people having trouble managing stress tend to have lower self-esteem.

Improved Menstrual Symptoms

Multiple studies suggest that yoga nidra could be a potentially effective treatment for unwanted symptoms related to menstruation.

Other Benefits

Initial studies have found that yoga nidra may provide other benefits such as:

• Increased alertness
• Faster reaction times
• Improved athletic performance
• Lowered blood pressure
• Slower heart rate
• Lowered blood sugar levels
• Reduced pain and inflammation

1. Lying in the shavasana pose, which is flat on your back with your hands apart 
2. Affirming a short, positive statement, called a sankalpa 
3. Mentally visualizing different parts of the body and becoming aware of where the body rests on the floor 
4. Focusing on breathing by visualizing air flowing in and out of the body 
5. Recalling sensations related to personal experiences, as well as opposite feelings, like pain and pleasure 
6. Visualizing specific scenes and emotions, often in a space just in front of the eyes 
7. Repeating the earlier sankalpa or positive statement 
8. Gradually returning awareness to the body, the room, and the present moment
