Green Noise for Sleeping: Unlocking Tranquil
Slumber with Nature's Serenade


David Webb (Owner, writer and host of All-About-Psychology.Com)


Green Noise for Sleeping

The concept of using distinct ambient sounds that match the frequency of natural environments to lull oneself into a peaceful sleep has become increasingly popular. Among these soothing sounds, "green noise" has emerged as a significant player, purporting to provide a serene ambiance purpose-built for promoting better quality sleep and rest. 


Green noise has become part of the sleep sounds meta trend; especially noticeable on TikTok, where a large online community has coalesced around the aim of enhancing sleep quality. According to explodingtopics.com, The hashtag #sleeptips has over 550 million views, approximately 30% of American TikTok users say they've used a sleeping hack they found on TikTok, and videos about sleep sounds have over 460 million views on the platform.


The Color of Noise


Before we delve into the topic of green noise for sleeping, it's important to acknowledge that various frequency concentrations are categorized into colors, and as such alternative "colors" of sound exist.


  • White noise encompasses all frequencies equally, resulting in a steady hiss akin to the static found on radios or televisions. It can resemble the continuous drone of a fan, a hair dryer, or a vacuum cleaner. White noise is commonly utilized to drown out surrounding noises, and many individuals find its constant static conducive to inducing sleep.


  • Brown noise, also referred to as red noise, emphasizes lower frequencies, resulting in a deep, resonant sound characterized by more bass and less static compared to white noise. For example, it may resemble the sound of the rumble of an airplane engine. Brown noise typically exhibits more natural fluctuations compared to other types of noise but similar to white noise, brown noise is effective in masking background noises.


  • Pink noise is characterized as a blend of white noise and brown noise. According to Shelby Freedman Harris, Psy.D., Director of the Behavioral Sleep Medicine Program at the Sleep-Wake Disorders Center at Montefiore Medical Center, it features a gradual decrease in high frequencies and resembles the gentle patter of rain. As such, it shares qualities with green noise in terms of its soothing auditory profile.

So What is Green Noise?


Put simply, it is a type of sound spectrum, the distinguishing feature of which lies in its emphasis on mid-range frequencies of around 500 hertz (Hz), that resemble natural sounds like ocean waves, flowing streams, the placid sounds of a peaceful forest, the gentle rustling of leaves, or the early morning chirping of birds. Green noise is believed to be the sweet spot of audio frequencies that our ears and mind typically find immensely pleasant and calming.



Limited Research on Green Noise and Sleep


There are studies which have shown the benefits of white noise in relation to sleep. In their study 'The effects of white noise on sleep and duration in individuals living in a high noise environment in New York City' Ebben, Yan and Krieger (2021), concluded that their data "show that white noise significantly improved sleep based on subjective and objective measurements in subjects complaining of difficulty sleeping due to high levels of environmental noise." Research on Pink noise has also yielded positive results. For example, research by Junhong, Z et al (2012) found that continuous pink noise had a notable impact on reducing the complexity of brain waves and promoting more consistent sleep patterns, thereby enhancing the overall quality of sleep.


While the popularity of green noise continues to rise, scientific research on its effect on sleep is currently lacking. As such, psychology students make want to take note that the use of green noise and its efficacy for improving sleep would be a great topic for a research project or final year thesis/dissertation.


Although the data is sparse, individuals seeking to block out external noises or alleviate racing thoughts and anxiety at night may find green noise worth exploring. Shift workers exposed to disruptive environmental sounds and parents of infants looking to create a conducive sleep environment may also consider incorporating green noise into their bedtime routines.


Green noise has become part of the sleep sounds meta trend, especially noticeable on TikTok, where a large online community has coalesced around the aim of enhancing sleep quality.


Applications and Access


The relaxing properties of green noise make it a potential aid to meditation practice such as mindfulness. As it mimics the nature of peaceful surroundings, green noise can be used to concentrate the mind on a specific object, thought, or task, cultivate attention and awareness, and attain a state of mental clarity, emotional calmness, and stability. Which in turn can become a pathway to tranquil slumber.


Advances in technology have made green noise for sleep widely accessible. From streaming platforms to specialized sleep apps, it's easy to find perfect green noise soundtracks for a night of serene, restful sleep or even for an afternoon snooze. Streaming platforms like Spotify, Apple Music, and YouTube have abundant resources when it comes to green noise. You'll find playlists devoted entirely to nature's lullabies that help induce peaceful sleep, with sounds ranging from rustling leaves to distant brooks to soft winds.


Apart from streaming platforms, sleep apps like Noisli, Sleepy Sounds, and Calm also offer customized green noise sounds, allowing you to find your perfect, tranquil sleep soundtrack and take control of your sleep. These platforms also present listeners with the option to customize their green noise audio tracks. For instance, you could mix the soothing sounds of rain with quiet forest sounds to create your unique blend, your calming companion for a restful night's sleep. There's a great sense of personalization with green noise which means there's a great chance you can find a sound mix suited to your individual taste and sleep pattern.


Green noise's popularity is beginning to extend beyond individual use. Offices, clinics, and yoga studios have started deploying green noise with the aim of creating a calming atmosphere, promoting relaxation, and reducing stress.


A Final Word


While incorporating green noise into your sleeping routine, there are a few practical tips you should consider. The volume of the green noise should be kept at a comfortable level; it shouldn't overpower your sleeping environment but merely blend subtly into the background. Also, the source of the green noise should preferably be positioned away from the bed, allowing the sound to disperse evenly throughout the room. This can enhance the overall calming effect and avoid any concentration of sound in one area.


Essentially, green noise for sleeping serves as a simple tool that individuals can use to try and enrich their sleep quality and possibly, their overall health. It's easily accessible, and can be customized to individual needs. Green noise for sleep is just one of many methods designed to enhance your sleep quality. Understanding and finding what works best for you can be engaging and fulfilling. And in this quest for optimal health, green noise for sleep might just be the melodious key to unlocking your peaceful slumber. so why not embrace the tranquility of green noise to see if it enhances your sleep experience.


Finally, it's important to mention that green noise is not a catch-all solution for sleep disorders. Those suffering from chronic insomnia, sleep apnea, or other sleep-related healthcare concerns should seek professional medical advice.
