Scientific research papers have consistently shown the usefulness of white noise for sleep. Studies have found that exposure to white noise during sleep improves sleep quality by increasing sleep efficiency, reducing awakenings, and promoting deep sleep stages. White noise also proves beneficial in masking disruptive sounds, creating a more serene sleep environment. Research conducted in intensive care units reveals that white noise machines significantly enhance sleep quality for patients. Furthermore, white noise helps mitigate the negative effects of external noise, such as traffic, on sleep patterns. Overall, white noise provides a consistent and soothing sound backdrop, facilitating a more restful and undisturbed sleep.
