What Is Green Noise?


Green noise, a variation of white noise, is believed to have potential sleep-inducing benefits. Unlike white noise, which contains equal volumes of all audible sound frequencies, green noise emphasizes frequencies in the middle of the range. White noise is commonly used to mask ambient sounds and improve sleep quality. Alongside other "colors" of sound like pink and brown noise, green noise is gaining attention as a tool to aid faster sleep onset. Although research on the specific effects of green noise on sleep is limited, it has garnered popularity on social media as a potentially helpful sleep aid.

Green noise, characterized by amplified mid-range frequencies, resembles natural sounds such as ocean waves or a gentle stream. In contrast, white noise maintains high frequencies, resulting in a continuous hissing sound similar to static on a television or radio. Due to its reduction of harsh high tones, green noise is generally perceived as more soothing and calming than white noise.


How Can Green Noise Benefit You?


Despite the growing promotion of green noise as a sleep aid, there is a shortage of substantial data demonstrating its efficacy in improving sleep. Research has primarily focused on white and pink noise, and the findings regarding the sleep-enhancing benefits of white noise have been inconclusive.


Certain studies indicate that individuals struggling to sleep in noisy surroundings may experience improved rest by using white noise during the night. Additional research suggests that adults could achieve faster sleep onset by incorporating white noise into their bedtime routine. Furthermore, white noise might have positive effects on cognitive symptoms in those with attention-deficit/hyperactivity disorder and memory in older adults with Alzheimer's.


How Do You Use Green Noise for Sleep?


While data on green noise remain limited, individuals interested in its potential sleep benefits can experiment with it at night. Begin by exploring the various green noise options accessible on streaming platforms. Adjust the volume to a soothing level that won't disrupt sleep. As adapting to new sounds may take time, it's advisable to give it a few nights to determine its effectiveness for you.
