From sounds of nature to the hums of ceiling fans and airplane cabins, playing white noise as a sleep aid has become popular. However, a newly published clinical review suggests that the practice may actually lead to more disrupted sleep.
In the systematic review, published in the journal Sleep Medicine Reviews, Mathias Basner, a professor of psychiatry at the University of Pennsylvania School of Medicine, along with colleagues Samantha M. Riedy, Michael G. Smith and Sarah Rocha, analyzed the scientific literature and identified 38 studies about continuous white noise as a sleep aid.
In their review, the researchers noted that “the quality of evidence for continuous noise improving sleep was very low, which contradicts its widespread use.”
Although there have not been tests on the subject, Basner is also concerned about the potential effects of not allowing such noise systems to switch off overnight.
The clinical review noted that “additional research with objective sleep measures and detailed descriptions of noise exposure is needed before promoting continuous noise as a sleep aid, especially since it may also negatively affect sleep and hearing.”
