If you didn’t see our Facebook post, this website called “Noisli” provides scientifically backed “Pink” noise for free. The site allows customization of a comfortable sound tailored to your desire and the opportunity to create a login to save those settings once you’ve found the perfect mix for you. Pink noise is the new evolution of noise therapy dominating white noise in research studies (See: https://www.ncbi.nlm.nih.gov/pubmed/8340228). Thus, helping many sleep with documented cognitive benefits without medication.
In a new study, researchers had volunteers sleep one night while listening to pink noise and another night without any noise. The next morning, they were asked to complete a memory test. Those who used pink noise therapy had a 30% higher score on memory tests. So apparently, pink noise not only helps you fall asleep faster and stay asleep as needed, but also has memory boosting benefits as well.
Dr. Phyllis Zee, (one of the study authors) had this to say:
“This is an innovative, simple and safe non-medication approach that may help improve brain health… This is a potential tool for enhancing memory in older populations and attenuating normal age-related memory decline.”
