The sound you can listen to at night that will help you get a good night's sleep: it boosts electrical waves and eliminates "brain waste" while you sleep.

Scientific researchers have identified a specific sound capable of enhancing sleep quality by stimulating electrical brain waves. This auditory intervention facilitates a biological cleaning process that removes waste products accumulated in the brain during waking hours.

This mechanism functions as part of the body's natural restorative cycle, which occurs while the individual is asleep. By boosting brain wave activity, the sound assists in the efficient clearance of metabolic debris, potentially improving overall sleep health.
