Could pink noise be the secret to deeper, more restful sleep?
Many people struggle to get enough sleep, according to the Centers for Disease Control and Prevention. While white noise is often recommended for sleep issues, pink noise may also offer benefits. This deeper-sounding alternative has drawn interest for its potential to improve rest.
Pink noise includes all audible frequencies but emphasises lower tones, creating a rich, steady sound. Examples include rustling leaves or the patter of steady rain. Unlike white noise, it sits between the higher pitch of white noise and the even deeper tones of brown noise.
Research on pink noise remains limited. A small 2017 study involving older adults suggested a link between the sound and deeper sleep. However, most studies focus on younger to middle-aged adults, aged 21 to 41. These found that pink noise reduced REM sleep by roughly 19 minutes per night.
Some evidence indicates it may lower brain wave activity and enhance sleep quality. To try it, people can play pink noise through a smartphone, computer, or sound machine. Adjusting the volume helps find the most comfortable level for sleep.
Poor sleep can harm focus, mental health, and physical well-being over time. Pink noise provides an alternative for those seeking better rest, though more research is needed. For now, experimenting with volume and sound sources may help individuals determine if it works for them.
