Non-sleep deep rest (NSDR) is a relaxation technique that guides your brain and body into a state of deep relaxation without falling asleep. The term was coined by Dr. Andrew Huberman, a neuroscientist and professor at Stanford University, to describe mindfulness practices such as yoga nidra, hypnosis, and meditation. NSDR helps slow down your thought flow and brain wave frequency, allowing your brain and body to rest deeply. It can be practiced any time of day or night and typically lasts between 10 to 30 minutes, providing relaxation, improved focus, and mental rejuvenation.

NSDR is a zero-cost tool that can be practiced anytime, anywhere
Non-Sleep Deep Rest (NSDR) is a zero-cost tool that can be practiced anytime, anywhere. It is a powerful practice that guides your brain and body into a state of deep relaxation without falling asleep. Dr. Andrew Huberman, a neuroscientist and professor at Stanford University, coined the term for this practice.
NSDR is an umbrella term for practices that direct the mind into a state of calm and focus. These techniques are not intended to induce sleep but to help you reach a dreamy, semi-focused state that occurs just before drifting off. The idea is that getting yourself to a sleep-like state for a short period allows the brain to rest intensely and can help you feel restored to take on the rest of your day.
NSDR sessions can vary in length but typically last between 10 to 30 minutes, depending on individual needs and preferences. Shorter sessions can be effective for relaxation and mental clarity. To enter NSDR, find a quiet place, close your eyes, and focus on deep breathing and relaxation techniques. You can also listen to one of the many free guided NSDR sessions available on YouTube and major music platforms, such as Apple Music and Spotify. These sessions can help facilitate this state by providing instructions and soothing sounds.
NSDR is a simple tool to overcome the postprandial dip in cognitive function (i.e., the 'afternoon slump') that typically occurs between 2-5 pm. It helps slow down your thought flow and brain wave frequency, allowing your brain and body to rest deeply. It can be especially beneficial for those who struggle with traditional meditation practices.

It is not a replacement for sleep but can complement it by providing relaxation and mental rejuvenation
Non-sleep deep rest (NSDR) is a powerful relaxation technique that can complement sleep by providing relaxation and mental rejuvenation. It is not a substitute for sleep but can be practised at any time of day or night to enhance overall well-being.
NSDR is a simple and accessible tool that can be used to achieve a state of deep relaxation without falling asleep. It involves slowing down one's thought flow and brain wave frequency, allowing the brain and body to enter a restorative state of deep rest. This practice can be particularly useful during the "postprandial dip in cognitive function", often referred to as the "afternoon slump", which typically occurs between 2-5 pm.
NSDR sessions typically last between 10 to 30 minutes and can be guided by scripts, videos, or apps that provide instructions and soothing sounds. These sessions can be done in a quiet place, lying down comfortably on a yoga mat or a soft surface. Before beginning, it is essential to set an intention, such as a positive affirmation or a personal goal, that can be silently repeated to oneself.
The effectiveness of NSDR lies in its ability to activate the parasympathetic nervous system, which is responsible for the relaxation response, also known as the "rest-and-digest" state. By increasing dopamine in the brain and reducing heart rate and blood pressure, NSDR promotes feelings of relaxation and mental clarity. It helps reduce stress and anxiety, improve focus, and enhance learning abilities.
While NSDR provides relaxation and mental benefits, it does not offer the full restorative power of a good night's sleep. However, it can be a valuable tool to improve sleep quality by helping individuals fall asleep more easily and empowering those with anxiety about getting sufficient sleep.

NSDR is not a replacement for sleep but can complement it by providing relaxation and mental rejuvenation. It helps reduce stress and improve focus but doesn’t offer the full restorative benefits of a full night’s sleep. NSDR can be particularly useful for those who struggle with traditional meditation or have anxiety about getting good sleep.
NSDR works by slowing down your thought flow and brain wave frequency, allowing your brain and body to rest deeply. It deactivates the sympathetic nervous system and activates the parasympathetic nervous system, increasing dopamine in the brain while reducing heart rate and blood pressure. This induces a state of relaxation with measurable benefits, including improved learning and retention.
