The practice of NSDR can reset specific neuromodulators in the brain, like dopamine in the striatum, which is involved in motor planning and execution. This reset can facilitate one's ability to deliberately engage with the world 4. Moreover, NSDR can be used in situations where sleep has been poor to aid in recovery and enable one to perform both mental and physical tasks more effectively on the following day 5.
