Pink noise reduces REM sleep and may harm sleep quality

Here's a summary for a newsletter: **The Surprising Effects of Pink Noise on Sleep** A recent study found that pink noise, often used as a sleep aid, may actually have negative effects on sleep quality. Unlike white noise, which is consistent and even, pink noise has a more natural, soothing sound. However, researchers discovered that exposure to pink noise during sleep can reduce REM (rapid eye movement) sleep, a crucial stage of sleep for physical and mental restoration. This reduction in REM sleep may lead to decreased sleep quality and potential long-term health consequences. The study's findings suggest that individuals using pink noise as a sleep aid should be cautious and consider alternative methods to improve their sleep.
