Non-Sleep Deep Rest: A Comprehensive Overview


Non-sleep deep rest (NSDR) has emerged as a captivating concept within the realm of relaxation techniques, promising a rejuvenating and energy-boosting alternative to traditional naps. However, this practice has also sparked questions regarding its distinction from existing meditation traditions and the validity of its purported health benefits.

Understanding Non-Sleep Deep Rest

NSDR encompasses relaxation techniques designed to induce a state of semi-focus and relaxation, akin to the liminal phase just before sleep onset. This state aims to provide a sense of restoration and revitalization. These techniques are often referred to as “NSDR protocols” and utilize specific breathing exercises and relaxation strategies to facilitate deep relaxation.

Distinguishing NSDR from Meditation

The creator of the term NSDR, neuroscientist Andrew Huberman, maintains that NSDR is distinct from meditation. He posits that NSDR offers a more accessible language and approach for individuals who may be averse to more spiritual or meditative practices. However, some researchers, such as cognitive neuroscientist Sara Mednick, contend that NSDR is, in fact, a form of guided meditation.

Scientific Basis and Potential Benefits of NRDS

While formal studies on NSDR are limited, a growing body of research on analogous relaxation practices, such as yoga Nidra, suggests potential beneficial outcomes. These include:

  • Reduced inflammation markers
  • Diminished stress and anxiety
  • Improved blood pressure regulation
  • Reduced age-related lower-back pain
  • Enhanced athletic performance and reaction time
  • Alleviated sleep disturbances, menstrual irregularities, and blood glucose levels
  • Elevated mood and well-being, particularly among elderly women

NSDR vs. Napping

Incorporating NSDR into one’s daily routine may be a viable option for replenishing energy levels. While comparable to a power nap, it is important to note that NSDR cannot fully replace the restorative benefits of sleep or extended meditation practices. Mednick emphasizes that deep sleep and prolonged meditation involve cognitive processes that are not present during NSDR.


NSDR emerges as a promising technique for relaxation and rejuvenation, with potential benefits supported by research on related practices. While questions remain regarding its distinction from meditation, its accessibility and ease of implementation make it a valuable addition to one’s self-care toolkit. Further research will shed light on the full extent of NSDR’s effects and solidify its place in the realm of relaxation techniques.
