Challenge 17: Do 10 minutes of NSDR
I have included a link below. NSDR (Non-Sleep Deep Rest), a term popularized by Stanford neurobiologist Dr. Andrew Huberman, works by intentionally guiding the brain through specific states of consciousness to trigger deep physiological recovery without requiring actual sleep. To be honest, it is very similar to the first 10 minutes of what I do with my clients during hypnotherapy.
Here is the breakdown of why this 10-minute reset is so effective for the nervous system:
1. Shifts the Autonomic Nervous System
Most of our day is spent in Sympathetic nervous system dominance (the "fight or flight" or "active" mode). NSDR uses breathwork and body scanning to actively engage the Parasympathetic nervous system (the "rest and digest" mode).
• The Mechanism: By slowing the breath and focusing internally, you send a physical signal to the brain that the environment is safe, lowering heart rate and cortisol levels.
2. Brain Wave Entrainment
During a 10-minute session, your brain waves transition from active Beta waves to slower Alpha and Theta waves.
• Alpha State: Associated with relaxed wakefulness and creativity.
• Theta State: The "twilight" state between waking and sleep. This is where the brain performs significant "housekeeping," processing emotions and clearing cognitive load.
3. Replenishes Dopamine and Acetylcholine
Research suggests that deep relaxation states like Yoga Nidra can increase dopamine levels in the nigrostriatal pathway by up to 65%.
• Neurochemical Reset: This replenishes the neuromodulators (dopamine and acetylcholine) required for focus, motivation, and motor control, which are typically depleted after hours of cognitive work or stress.
4. Enhances Neuroplasticity
By entering a state of "calm alertness," you create an ideal environment for neuroplasticity. This 10-minute "reset" allows the brain to consolidate information and "offload" the mental fatigue that builds up during high-pressure tasks.
Because NSDR keeps you in a state of "conscious sleep," it is often more effective than a nap for people who struggle with "sleep inertia"—that heavy, groggy feeling that can occur after waking up mid-day.
