NSDR

Understanding Non-Sleep Deep Rest

Explore the concept of NSDR, its benefits, and how to practice it effectively.

What Is Non-Sleep Deep Rest (NSDR)?

The relaxation technique non-sleep deep rest (NSDR) is steadily growing in popularity. Andrew Huberman, Ph.D., a neuroscientist and professor at the Stanford School of Medicine, coined the term for this practice. Huberman has discussed NSDR widely, including on popular podcasts by Tim Ferriss and Joe Rogan. Multiple high-profile people, like Google CEO Sundar Pichai, say they practice the technique.

NSDR involves entering a state of deep relaxation without actually falling asleep. This technique combines elements of guided meditation, yoga nidra, and deep breathing exercises to achieve profound rest and rejuvenation.

How Does NSDR Work?

NSDR helps a person enter deep relaxation through breathing, visualization, and attention exercises. These practices decrease activity in the sympathetic nervous system while activating the parasympathetic nervous system, promoting feelings of relaxation, increasing dopamine in the brain, and reducing heart rate and blood pressure. This shift can lead to a profound state of rest and recovery [17][18].

By deactivating the sympathetic and activating the parasympathetic nervous system, NSDR may promote feelings of relaxation by increasing dopamine in the brain, while reducing heart rate and blood pressure [18].

NSDR vs. Yoga Nidra

Initially, Huberman coined “non-sleep deep rest” (NSDR) as a Westerner-friendly term for the ancient Eastern practice of yoga nidra. Yoga nidra, also called yogic sleep, involves lying flat on one’s back and listening to guided imagery, leading to total relaxation. Huberman expanded NSDR to include various practices like hypnosis and meditation, making it accessible to a broader audience [19][20].

Yoga nidra, also known as yogic sleep, is a practice that involves lying flat on your back and listening to guided imagery, leading to a deeply relaxed state of consciousness with brain activity similar to sleep, though you remain awake. Over time, Huberman expanded NSDR to include various types of deep relaxation practices like hypnosis and meditation, making it accessible to a broader audience [18][20].

Potential Benefits of NSDR

Stress Reduction and Relaxation

NSDR can help reduce stress and promote relaxation. By shifting the brain into a state similar to sleep, but while awake, NSDR helps decrease anxiety, reduce cortisol levels, and increase dopamine release, enhancing mood and relaxation [18][21].

Improved Sleep Quality

Practicing NSDR can improve sleep quality and overall well-being. It helps manage sleep disorders and enhances the transition to sleep by training the brain to enter a relaxed state, making it easier to fall asleep [19][22].

Enhanced Cognitive Function

Studies have shown that NSDR can accelerate neuroplasticity, improving learning and memory retention. Regular practice can enhance focus, attention, and cognitive performance, making it beneficial for both mental and physical health [21].

Faster Learning and Better Retention

NSDR has been found to accelerate neuroplasticity by about 50%, improving learning and memory retention. This practice can help in skill acquisition and cognitive tasks, making it a valuable tool for both personal and professional development [21].

How to Practice NSDR

To practice NSDR, find a comfortable seated or lying position and close your eyes. Follow a guided session, which may involve:

  1. Intention Setting: Begin with a positive intention to anchor your practice.
  2. Body Scan: Focus on different parts of your body systematically to release tension.
  3. Deep Breathing: Use specific breathing patterns to promote relaxation.
  4. Visualization: Imagine peaceful scenes to enhance relaxation [18][20].

Detailed NSDR Steps

  1. Deep Breathing: Inhale through your nose, then exhale through your mouth with pursed lips, as if blowing through a straw. This helps slow the heart rate and promotes relaxation.
  2. Body Scan: Visualize a spotlight illuminating various parts of your body, starting from your feet and gradually moving upwards. Focus on the sensations and imagine your body sinking into the surface.
  3. Guided Imagery: Visualize peaceful scenes, such as a garden or beach, to further enhance relaxation.
  4. Gradual Awakening: Slowly move your toes, ankles, knees, upper body, and head to reassert control over your nervous system before opening your eyes [18].

Regular Practice and Consistency

Consistency is key to reaping the benefits of NSDR. Even a few minutes daily can make a significant difference in relaxation and mindfulness over time. Huberman recommends 10 to 30 minutes daily, but traditional yoga nidra sessions can last up to an hour [19].

Who Should Practice NSDR?

Anyone can practice NSDR, especially those looking to reduce stress, improve sleep, and enhance cognitive function. It is adaptable and can be practiced at any time of day, depending on your needs [21][22].

When to Practice NSDR

Depending on your goals, you can practice NSDR at different times. For instance, practice it during the day to combat stress or before bed to improve sleep quality. Regular practice can help integrate NSDR into your daily routine for maximum benefits [20].

Conclusion

NSDR is a powerful tool for achieving deep relaxation and improving mental and physical well-being. Its simplicity and accessibility make it an ideal practice for anyone seeking to cultivate a deeper sense of calm and resilience. By incorporating NSDR into your daily routine, you can experience significant improvements in your life.
