‘Pink Noise’ Might Be the Secret to Better Sleep and Improved Memory

You’ve heard before that white noise – aka constant, ambient sound – can help you fall asleep faster and snooze sounder. (Even the National Sleep Foundation recommends itfor people who have trouble catching zzzs.) But there might be a more effective sleep soundtrack in town: pink noise.

As TIME defines it, pink noise is “a mix of high and low frequencies that sounds more balanced and natural” than the better-known white noise. And according to new research published in Frontiers in Human Neuroscience, pink noise just might be the secret to better sleep… and improved memory (bonus!).
