Bursts of ‘pink noise’ during sleep seem to help clear waste from brain
The human brain flushes out waste products while we sleep and now it seems that certain sounds might enhance the process
Bursts of pink noise during sleep may aid in clearing waste from the brain, according to recent research. Pink noise, characterized by gentle static sounds similar to radio static, appears to enhance the flow of cerebrospinal fluid (CSF) within the brain, potentially improving the removal of waste products associated with diseases like Alzheimer's.
The study found that pink noise strengthens slow brainwaves, which in turn boost the pumping of blood vessels, driving the brain's waste-disposal system known as the glymphatic system.
