Pink Noise Improves Sleep, Memory in Older Adults, Study Finds

Written by 

You’ve likely heard of white noise as a way to block out distracting sound. However, a new trend has experts recommending pink noise, which is a slightly higher-pitched version. And research indicates you may get a more restful sleep with a pink noise generator on your nightstand.

A 2017 study published in Frontiers in Human Neuroscience revealed that participants who used pink noise not only got more restful sleep, but they also demonstrated memory improvement. A previous study had already found memory improvement among younger adults who used pink noise during sleep. But this study showed the memory benefits of pink noise in older adults.

For the study, 13 adults who were 60 years of age or older were monitored in a sleep lab for two consecutive nights. On one night, the participants were memory-tested both before and after a full night’s sleep listening to pink noise through headphones. They also wore electrode caps to monitor their slow-wave oscillations. On the other night, no pink noise was played.

During the night where they listened to pink noise, the sleepers showed three times the memory recall on tests. Their slow-wave oscillations also increased with pink noise playing.
