Pink Noise: The Noise That Helps You Sleep Better

You’ve tried just about everything but with work, school, kids, a busy schedule and LIFE happening – it’s hard to get enough time to sleep. Or maybe you found enough time to sleep but you still wake up tired. Don’t throw in the towel just yet.

You’ve heard that white noise can help you fall asleep faster and snooze sounder. The National Sleep Foundation recommends it for people who have trouble sleeping. But according to science pink noise may be the new white noise.

Pink noise is a mix of high and low frequencies that sound more balanced and natural than white noise. Examples of this are rain falling on pavement, or wind rustling the leaves on a tree. It’s called pink noise because light with a similar power spectrum would appear pink.

According to new research published in Frontiers in Human Neuroscience, pink noise just might be the secret to better sleep and improved memory.

In the small recent study, Northwestern University researchers invited adults to spend some time in a sleep lab. Both nights, the participants took a memory test, went to bed wearing headphones and an electrode cap, and retook the memory test when they woke up.
