Pink noise reduces REM sleep and may harm sleep quality

Here's a summary of the article for a newsletter: **Pink Noise May Disrupt Sleep Quality** A recent study found that exposure to pink noise during sleep can actually reduce REM sleep and potentially harm overall sleep quality. Pink noise, a type of noise that includes all audible frequencies at equal intensity, is often touted as a sleep aid. However, the study suggests that it may have the opposite effect. Researchers found that participants who listened to pink noise during sleep experienced reduced REM sleep, which is essential for memory consolidation and learning. This study's findings contradict the common assumption that pink noise is beneficial for sleep, and more research is needed to fully understand its effects.
