What Is Green Noise & Can It Help You Sleep?


Green noise - Dr. Axe

Green noise, often described as the “background noise of the world,” is a type of sound that sits between white noise and brown noise on the sound spectrum. It’s characterized by a concentration of midrange frequencies, similar to the sounds of rustling leaves, trickling streams or gentle rain.

While not an official scientific term, green noise has gained popularity in recent years for its potential benefits in promoting relaxation and sleep. Let’s delve deeper into the world of green noise.

What Is Green Noise?

Green noise is a type of noise that is characterized by its gentle and soothing qualities, often resembling the sound of rustling leaves or a gentle breeze blowing through the trees. It is a term derived from the concept of white noise, which is a combination of all audible frequencies, and is sometimes referred to as “nature’s white noise.”

It is specifically designed to mimic the sounds of nature, promoting relaxation and tranquility. It can help drown out disruptive noises and create a calming environment conducive to sleep, relaxation and focus.

Green noise is a type of sound that sits between white noise and pink noise on the sound spectrum. It’s often described as sounding like rustling leaves, a gentle breeze or a babbling brook. Unlike white noise, which has equal energy at all frequencies, green noise has more energy in the lower and middle frequencies, similar to the sounds found in nature.

Some people find green noise to be more relaxing than white noise, as it is less harsh and can be more reminiscent of nature. Unlike white noise, which has equal energy across all audible frequencies, it has a more balanced distribution, with slightly more emphasis on the middle range. This makes it sound less harsh and more natural to our ears, resembling the ambient sounds we often encounter in nature.


1. Better Sleep

One of the primary benefits of green noise is its ability to promote sleep. It can help mask intrusive sounds that may disrupt your sleep and create a more peaceful atmosphere. The gentle and constant sound can lull you into a deep and uninterrupted sleep.

Green noise may help you fall asleep faster and sleep more soundly by masking disruptive sounds and promoting relaxation. Some studies have shown that it can be even more effective than other white noise for sleep.

Studies suggest that this type of noise can mask disruptive sounds and create a calming environment, leading to better sleep quality and duration.

2. Stress Reduction

Green noise can help to reduce stress and anxiety by promoting relaxation. The natural sounds it emits have a calming effect on the mind and body. Listening to green noise can create a sense of being in a peaceful outdoor environment, which can help reduce tension and promote a state of relaxation.

The gentle, natural sounds of green noise can trigger the relaxation response in the body, lowering cortisol levels and promoting feelings of calm. This is because it is believed it can help lower your heart rate and blood pressure.

3. Improved Focus and Concentration

Green noise can also be beneficial for improving focus and concentration. It can help block out distracting noises and create a steady background sound that enhances productivity. Listening to green noise while studying or working can help you stay focused and engaged.

In fact, research published in 2021 examined the effects of using an app with nature sounds on the well-being and cognitive performance on college students. After four weeks of exposure to this green noise, “the students in the experimental group outperformed their counterparts in the control group on psychological well-being reflected in positive affect, as well as cognitive performance reflected in flow state, attention (in terms of alerting) and working memory (in terms of accuracy and reaction time).”

This can be helpful for students, workers and anyone who needs to concentrate on a task.

4. Tinnitus Relief

For some people with tinnitus, the constant ringing in the ears can be alleviated by green noise, which can mask the tinnitus sound.

Tinnitus, a condition characterized by the perception of ringing or buzzing in the ears, can be quite bothersome. Green noise is often recommended as a form of sound therapy to alleviate tinnitus symptoms. The soothing nature sounds can help distract from the ringing sensation and provide relief.

How to Use Green Noise for Sleep

Using green noise to aid in sleep is simple and straightforward. Here are a few tips to make the most of it:

  • Choose a reliable source: There are numerous apps, websites and devices available that offer green noise options. Make sure to select a reputable and reliable source to ensure the quality of the sound.
  • Find the right volume: Experiment with different volume levels to find what works best for you. Some people prefer a lower volume to create a subtle background sound, while others find a slightly higher volume more effective in masking unwanted noises.
  • Consistency is key: Use green noise consistently every night as part of your sleep routine. This will help signal your brain that it’s time to relax and wind down for sleep.
  • Consider using a sound machine: If you find it challenging to create a consistent and peaceful environment, investing in a sound machine specifically designed for green noise can be beneficial. These devices offer a range of nature-inspired sounds, including green noise, to help you achieve a more restful sleep experience.
  • Play green noise recordings: There are many green noise recordings available online and in apps. You can also create your own green noise recordings using a sound machine or white noise generator.
  • Use a fan: The sound of a fan can create a similar effect to green noise.
  • Listen to nature sounds: Nature sounds, such as the sound of waves or rain, can also be helpful for sleep. If you live near a park, forest or ocean, open your windows at night to let in the natural sounds of nature, which can provide a similar effect to green noise recordings.
  • Play green noise recordings: Numerous websites and apps offer green noise recordings, which you can play through headphones or speakers.

Here are some more tips on using green noise:

  1. You can listen to green noise recordings online or through apps. There are also green noise machines that you can buy.
  2. Start by playing green noise at a low volume, and gradually increase the volume until you find a level that is comfortable for you.
  3. Set a timer for 30 minutes to an hour. You don’t want to listen to green noise all night, as it can disrupt your sleep cycle in the long run.

Should You Try It?

If you struggle with falling asleep, frequently wake up due to noise disturbances or are looking for a way to create a more peaceful environment, green noise can be a useful tool to consider. Its natural sounds can help calm your mind and promote a deeper and more restorative sleep.

However, it’s essential to remember that everyone’s sleep preferences and needs are different. While green noise works for many individuals, it may not be effective for everyone. If you find that it doesn’t improve your sleep quality or feel uncomfortable using it, you may need to explore other sleep-enhancing techniques.

If you have trouble sleeping, are stressed or anxious, or have difficulty concentrating, green noise may be worth trying. It’s a safe and natural way to improve your sleep, reduce stress and boost your focus.

However, it’s important to note that green noise is not a miracle cure, and it may not work for everyone. If you find that green noise is not helping you, there are other things you can try to improve your sleep, such as practicing good sleep hygiene and relaxation techniques.

Whether or not green noise works for you depends on individual preferences. Some people find it incredibly relaxing and helpful for sleep, while others might prefer the harsher sounds of white noise or the deeper rumble of brown noise.

It’s worth experimenting with different types of noise to see what works best for you.
