Many people use rain, flowing water, ocean waves or forest ambience to create a calmer environment at bedtime. A continuous nature sound for sleeping may make sudden background noises less noticeable and give the mind a predictable sound on which to settle.
Can Nature Sounds Help You Sleep? Research suggests that natural soundscapes may support relaxation and make intrusive environmental noise less noticeable, but they have not been established as a medical treatment for insomnia.
Nature sounds have been studied in relation to stress, pain, mood, physiological recovery and environmental noise. The evidence is encouraging, but it must be described accurately.
For practical guidance on choosing a recording, setting a comfortable volume and deciding whether to use a timer, read How to Listen to Nature Sounds for Sleep and Relaxation.
The Study: Health Benefits of Natural Sounds
A 2021 systematic review and meta-analysis published in the journal Proceedings of the National Academy of Sciences examined research into the health effects of natural sounds.
Researchers identified 36 relevant publications, with 18 providing sufficient numerical information for inclusion in the meta-analysis. The studies investigated water, birdsong and mixed natural soundscapes in laboratory, clinical and real-world settings.

Can Nature Sounds Help You Sleep According to Research?
Across the included studies, exposure to natural sounds was associated with:
Reduced stress and annoyance
Improved mood and positive emotional responses
Greater perceived relaxation and restoration
Reduced perceived pain in some clinical settings
More positive assessments of the surrounding environment
Partial masking of unwanted human-generated noise
The researchers reported an overall reduction in stress and annoyance among groups exposed to natural sounds compared with control conditions. They also found improvements across a broader category of health and positive-affect outcomes.
Different sounds appeared to have different strengths. Water sounds produced the strongest average results for health and positive emotional outcomes, while birdsong produced the strongest results for reducing stress and annoyance.
These findings do not mean that listening to nature sounds is guaranteed to make someone sleep. Sleep was not the principal outcome measured by these 18 studies. A more accurate conclusion is that nature sounds may create conditions favourable to sleep by supporting relaxation and making intrusive environmental noise less noticeable.
Nature Sounds Compared With Traffic Noise
One experiment included in the review directly investigated recovery from psychological stress while participants listened to natural sounds, traffic noise, ordinary ambient noise or silence.
The study involved 40 university students. Following a stressful mental-arithmetic task, participants listened to each sound condition for four minutes. The nature recording contained fountain water and birdsong.
The researchers found that recovery in skin conductance—a measure associated with sympathetic nervous-system activity—was faster during the nature-sound condition than during the environmental-noise conditions. Participants also rated the nature sound as more pleasant.

The experiment investigated short-term stress recovery rather than sleep. It therefore does not tell us whether nature sounds should play for 20 minutes, several hours or throughout the night.
Listen to Three Nature Sound Samples
The three 15-second videos below introduce different elements of a natural soundscape: wind, birdsong and water drops. They are short listening samples—not complete relaxation or sleep recordings—and are designed to help you notice which type of sound feels most comfortable.
Keep the volume low and listen to each sample once. Notice whether the sound feels calming, attracts your attention or reminds you of a familiar natural environment.
Wind Through the Trees
Gentle wind through leaves creates a soft, spacious atmosphere. It may suit relaxation and quiet background listening, although strong gusts or microphone noise can be too stimulating for sleep.
Birds in a Natural Setting
Birdsong can add life and a sense of place to a soundscape. The review found promising results for birdsong in relation to stress and annoyance. However, close or repetitive calls may attract attention and are generally more suitable for daytime relaxation than overnight listening.
Water Drops in a Forest Stream
Water drops and a gently moving stream provide a close, detailed natural sound. The review found that water sounds produced the strongest average results for health and positive emotional outcomes.
For sleep, a longer recording containing steady flowing water is usually more predictable than individual water drops.
After listening, consider which sound required the least attention. That may be the best starting point when choosing a longer nature recording for relaxation. For sleep, look for a continuous version without abrupt changes, obvious loops or unexpected human and environmental noise.
Which Nature Sound Should You Choose?
The most suitable recording depends on what you want the sound to do.
Gentle Rain for a Consistent Background
Steady rain provides a soft and relatively uniform acoustic background. It can be useful when you want to soften quiet household activity, distant voices or occasional traffic.
Choose rain without thunder, sudden downpours or dramatic changes in intensity.
Streams and Small Waterfalls for Masking Noise
Flowing water contains a broad range of frequencies and can help make changes in environmental sound less noticeable. A woodland stream or small waterfall may be particularly useful for people living near roads or in busy households.
The water should sound smooth and continuous rather than loud or forceful.
Calm Ocean Waves for Rhythmic Relaxation
Slow, regular waves provide a natural rhythm that some listeners find calming. They work best when the difference between each approaching wave and the quieter interval is not too pronounced.
Avoid recordings containing crashing surf, strong coastal wind or nearby gulls if the recording will play during sleep.
Forest Ambience for Rest and Relaxation
A quiet forest soundscape can create a strong sense of place. Leaves, distant water and subtle wildlife may be suitable for reading, meditation or relaxing before bed.
For overnight listening, select a recording in which the background ambience remains dominant and individual animal calls are infrequent.
Birdsong for Mood and Daytime Restoration
Birdsong showed promising results for reducing stress and annoyance in the 2021 review. However, it can be more attention-grabbing than rain or flowing water.
A gentle dawn chorus may be suitable for relaxation, mood or a peaceful morning routine. For sleep, distant and subdued birds are likely to be more appropriate than loud, frequent or unpredictable calls.
Sounds to Avoid When Sleeping
A sound can be completely natural and still be unsuitable for sleep. The main concern is not whether the source is natural, but whether it is loud, abrupt or likely to capture attention.
Consider avoiding:
Thunder and sudden changes in rainfall
Crashing waves with large changes in volume
Strong wind hitting the microphone
Loud or repetitive bird calls
Crows, gulls, owls and woodpeckers close to the microphone
Nearby barking or other sudden animal sounds
Buzzing insects recorded very close to the microphone
Traffic, horns, motorcycles, aircraft and sirens
Human voices or footsteps
Music that changes in volume, tempo or instrumentation
Short, repetitive loops that become easy to recognise
Recordings with abrupt edits, fades or changes of location
For bedtime use, a predictable recording is generally preferable to a dramatic one.
How Long Should Nature Sounds Play?
Research has not established an ideal listening duration for sleep.
The four-minute exposure used in the stress-recovery experiment cannot be extended into a recommendation for an overnight recording. It does not establish that four minutes improves sleep or that longer playback produces greater benefits.
The duration of a nature recording is therefore a practical choice rather than a medically established dose. Some people may prefer a short timer while relaxing before sleep. Others may choose continuous playback to mask environmental noise that continues throughout the night.
How to Listen Safely and Comfortably
Nature audio does not need to be loud. Set the volume only high enough to soften distracting background noise while allowing the recording to remain part of the environment.
A bedside speaker placed at a reasonable distance is often more comfortable than wearing headphones throughout the night. If you do not want the recording to continue until morning, use a sleep timer.
Most importantly, choose a sound you personally find pleasant. Responses to natural sound vary, and a recording that relaxes one person may distract another.

The Evidence-Based Conclusion
Research supports the use of natural sounds for relaxation, stress recovery, positive mood and reducing the perceived impact of environmental noise. Among the sounds studied, water and birdsong produced particularly promising results.
For sleeping, steady rain, a gentle stream or a small waterfall are sensible choices because they combine a natural atmosphere with consistent noise masking. Birdsong may be better suited to relaxing before bed or waking gently unless the calls are soft and distant.
Nature sounds should be presented as a supportive part of a calm bedtime environment—not as a cure or clinically proven treatment for insomnia. Persistent sleep difficulties should be discussed with a GP or another qualified healthcare professional.
Frequently Asked Questions
Can Nature Sounds Help You Fall Asleep?
Nature sounds may help some people relax and make intermittent environmental noise less noticeable. This can create a more comfortable bedtime environment, but research has not established that nature sounds directly cause or guarantee sleep.
Which Nature Sound Is Best for Sleeping?
Gentle rain, a steady stream and a small waterfall are sensible starting points because they provide continuous, predictable sound. The best choice is one that feels comfortable and does not repeatedly attract your attention.
Are Water Sounds Good for Sleep?
Water sounds can provide a consistent acoustic background and may soften changes in traffic, voices or household noise. Choose recordings without sudden splashes, dramatic volume changes or obvious short loops.
Is Birdsong Suitable for Sleeping?
Soft, distant birds may make a natural soundscape feel peaceful. Close, loud or repetitive calls can attract attention, so an active dawn chorus may be better suited to daytime relaxation or a morning routine.
Can Nature Sounds Mask Traffic Noise?
Rain, streams and waterfalls can reduce the contrast between a quiet room and individual passing vehicles. They may not completely cover nearby horns, motorcycles, aircraft or sirens and should not be played excessively loudly.
How Loud Should Nature Sounds Be at Night?
Keep the volume low enough for the recording to remain in the background. It should soften distracting noise without dominating the room, causing discomfort or preventing you from hearing an alarm or another important signal.
How Long Should Nature Sounds Play?
Research has not established an ideal listening duration. You can begin with a sleep timer and extend it if the sound remains comfortable. Continuous playback may be useful when recurring environmental noise continues throughout the night.
Is It Better to Use a Speaker or Headphones?
A speaker positioned at a comfortable distance is often more practical for prolonged or overnight listening. Headphones may become uncomfortable during sleep and place the sound very close to the ears.
Can Nature Sounds Treat Insomnia?
No. Nature sounds may support relaxation and improve the perceived sleeping environment, but they are not a clinically established treatment for insomnia. Persistent sleep problems should be discussed with a GP or another qualified healthcare professional.
