Sleep aids are increasingly popular as people prioritize better rest, and color noises — ranging from white to pink, brown and even blue — are among the latest trends, according to a recent "A Healthier Michigan Podcast." Host Chuck Gaidica explored the science and practical uses of color noise with Laura Hatton, manager of Behavioral Health Parity at Blue Cross Blue Shield of Michigan.
Color noises such as white, pink and brown represent different sound frequencies. White noise contains all audible frequencies, similar to white light, and is familiar to many as the "shhh" sound or the hum of an air conditioner. Pink noise is deeper and emphasizes lower frequencies, often resembling ocean waves, while brown noise amplifies even lower tones, similar to heavy rain or a waterfall. Hatton explained that these sounds are not inherently good or bad; instead, their impact varies based on individual preferences and past experiences.
Noise can play a crucial role in sleep quality by masking disruptive sounds — like barking dogs or traffic — and creating a consistent soundscape that calms the brain. For some, familiar background noises from childhood, such as thunderstorms or fans, provide comfort and help signal the body that it’s time to rest. Technology now allows anyone to import their preferred noise through apps, machines or smart earbuds, making it easier than ever to tailor a sleep environment.
Research shows pink noise may improve attention and concentration, benefiting not only sleep but also focus in busy environments. Hatton recommended experimenting with different noises, as wellness strategies are highly personal. Free apps and YouTube channels offer a range of options, including train tracks, waterfalls and city sounds, so users can discover what works best for them.
Noise-canceling headphones and devices are another tool, providing silence for those who prefer no ambient sound. Ultimately, Hatton encouraged listeners to try various approaches, noting that trial and error is key for finding the most effective sleep aid.
As sleep and mental health are closely connected, color noises offer an accessible way to improve both, whether for relaxation, concentration or restful sleep. For more information and wellness tips, visit ahealthiermichigan.org/podcast.
