A study by MIT scientists finds that listening to short, timed bursts of pink noise during sleep can encourage the flow of cerebrospinal fluid, which clears the brain of “harmful particles that increase your risk for neurodegenerative disease,” writes Scientific American reporter Alex Music. “If validated by future work, selective noise-playing could potentially unlock more restorative sleep in a home environment,” notes Music. “They’re particularly interested in testing the method in older individuals and in people with sleep disorders.”
