Insomniacs rejoice! There’s a new lullaby in town and its called pink noise.
This wonderful creation is similar to white noise but, according to AskMen, it’s quieter and more relaxing. Scientists have just concluded that listening to it overnight can lead to deeper, more restorative and better sleep.
The study, published in the journal Frontiers in Human Neuroscience, observed adults who were made to listen to pink noise as they slept in a laboratory. The next day, they reported feeling more rested than usual.
But that’s not all. The study participants were each asked to complete a task 90 minutes before “lights out,” where they viewed word pairs and were asked to memorise and recall them. In the morning, one hour after waking up from their pink noise-induced slumber, they were given a second test and performed three times better in the tests the morning after, compared to another night in the sleep lab, where no sounds were played, but the set-up remained the same.
According to the researchers, listening to pink noise – or what they also refer to as “acoustic stimulation” – while sleeping can increase “slow wave activity” in the brain, and improve sleep-dependent memory retention.
And the best part is that you can get your hands on some of the good stuff via YouTube, where there’s hours’ worth of pink noise to listen to.
