Deep Sleep Guaranteed: Discover the Benefits of Sleep Sounds

Can listening to sleep sounds help achieve and maintain healthy sleep patterns for individuals having trouble sleeping?

Sleep Sounds

Sleep sounds include white, pink, green, or brown noise, binaural beats, ASMR, nature, and ambient sounds. Each has different benefits and can potentially improve sleep. (Ebben M. R., Yan P., & Krieger A. C. 2021) Sound has no color, but it follows a spectrum. The color of a sound refers to the power spectrum of a particular noise signal. Each color has different qualities.

  • White noise, such as an untuned radio or television, is the most well-known background noise and is often used as a sleep aid.
  • Green noise features more powerful mid-range frequencies.
  • Brown noise is a more low-frequency rumble deeper than green and white noise.
  • Pink noise combines white noise softened by brown and could be the most effective option for improving sleep.

White noise is a sound that includes all the audible frequencies at equal volume, like a continuous hiss. One study found that adults fell asleep faster while listening to white noise. (Messineo L. et al., 2017)

Green noise, which features more powerful mid-range frequencies, is similar to natural sounds like ocean waves, rainfall, and rustling leaves. It’s more soothing than white noise and can help individuals with anxiety sleep better.

Brown noise, also known as red noise, has a deeper tone than white noise and is similar to the hum of an airplane. It can help mask lower-pitched sounds and may be especially helpful for individuals with ADHD, as it aids in productivity and concentration. Brown noise mimics sounds found in nature but with a low-frequency rumble. Examples include heavy rainfall, thunder, or loud waves.

Pink Noise

While further scientific research on sleep noise is needed, evidence has begun to suggest that pink noise may be the most effective option for improving sleep. (Ong J. L. et al., 2016) Pink noise is softer and more soothing than the other colored sleep sounds. It combines white noise softened by brown noise and is considered more relaxing because of its lower pitch. It has a pleasant-sounding, balanced volume across frequencies, making it calming to the human ear. Pink noise includes digital recreations of natural sounds such as a gently flowing stream, soft rain falling, wind rustling through trees, or calm waves lapping at the shore.

In a study, adults over 60 were given intermittent bursts of pink noise while sleeping, similar to rushing water. (Papalambros N. A. et al., 2017) The following morning, participants were given memory tests, which indicated that retention levels were approximately three times greater than those of the control group not exposed to the pink noise. Another study found that steady pink noise significantly reduced brain wave complexity during sleep while improving stable sleep time with less fragmentation and fewer wake periods. (Zhou, J. et al., 2012)

Injury Medical Chiropractic and Functional Medicine Clinic

Choosing the right sound for you ultimately comes down to personal preference. Individuals can try each color and see which one they like best. Individuals who struggle with sleep or other sleep disorders that impact their ability to get restful sleep should consult with their healthcare provider about getting an assessment and treatment to restore health. Individuals can recover and regain the benefits of quality rest through healthy sleep practices and lifestyle accommodations. Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to build optimal health and wellness solutions. We focus on what works for you to relieve pain, restore function, prevent injury, and help mitigate issues through adjustments that help the body realign itself. They can also work with other medical professionals to integrate a treatment plan to resolve musculoskeletal problems.

Sleeping with Lower Back Pain and Sciatica: Finding Relief 

Sleeping with lower back pain and sciatica can be difficult and frustrating. What are ways to get more comfortable sleep?

Sleeping With Lower Back Pain and Sciatica

Various factors can affect sleeping with lower back pain and sciatica, including age, injury and medical history, the mattress (e.g., soft vs. firm mattress), and sleep positions. Unfortunately, there’s no one-cure-all solution for this problem, and depending on the underlying cause/s, they can worsen the pain and cause sleep problems. For example, if a herniated disc places added pressure on the nerves in the lower back, twisting the spine can worsen the lower back pain, and sleeping in a fetal position can exacerbate the nerve pain. (UCF Health, N.D.)

Lower-Back Pain

Low-back pain can be activity-related, intermittent, or constant. (American Association of Neurological Surgeons, 2024) For some, it only occurs occasionally, such as when performing specific movements. For others, it can be excruciating, chronic, and disabling. Low-back pain is unique for everybody and can differ depending on the cause. Some low-back pain symptom descriptions include (Förster M. et al., 2013)

  • Aching pain deep in the back
  • Shooting pain flare-ups
  • Pain caused by slight pressure
  • Burning
  • Tingling

Sciatica Not Present

For some, low-back pain may be confined to a specific area known as axial back pain. (Förster M. et al., 2013) The pain may be felt in a band along the lower back and does not radiate down the legs or anywhere else.

Sciatica Present

Low-back pain with sciatica pain that radiates from the lower back or hip down the leg is the most common symptom of lumbar radiculopathy (compression of spinal nerve roots). (North American Spine Society, 2020) Sciatica symptoms include: (American Academy of Orthopaedic Surgeons, 2021)

  • Shooting pain from the lower back down the leg
  • Feeling like a bad leg cramp
  • Leg weakness
  • Sensory changes radiating down the leg – numbness, burning, and or tingling

Sleep Tools

Consider changing the mattress to improve sleeping with lower back pain and sciatica. For the best spinal support, choose a medium to firm mattress. Pillows, wedges, and other tools can also help improve sleep. (UCF Health, N.D.) It is recommended that individuals who sleep on their backs place a small pillow under their knees to reduce pressure on their lower backs. For those who sleep on their side, placing a pillow between the knees can keep the spine in a neutral/straight position. To relieve lower back pain, consider sleeping in a reclined, angled position with the head and shoulders higher than the hips. This can be accomplished with an adjustable bed or a wedge to prop the body in a regular bed.

Back Sleeping

Easing back pain while sleeping involves maintaining the body in a neutral or straight position. Extending the muscles, tendons, and ligaments too far in any one direction while sleeping with lower back pain and sciatica can cause stiffness, muscle spasms, and pain. Sleeping on the back puts the spine in neutral alignment with the least stress on the neck and back. It evenly distributes body weight to avoid exerting pressure on the joints and prevent backaches. In addition, a supine position allows outstretched ligaments to shrink and recover to their normal positions. (Keck Medicine of USC, 2019)

Chiropractic Assessment

Chiropractic care aims to help individuals improve movement with less pain due to condition, after injury, or surgery. A chiropractic physical therapy team may be best for individuals with acute back, neck, and musculoskeletal pain and discomfort symptoms. A chiropractor can quickly assess your condition and develop a customized treatment plan to expedite pain relief and improve mobility. Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to build optimal health and wellness solutions. We focus on what works for you to relieve pain, restore function, prevent injury, and help mitigate issues through adjustments that help the body realign itself. They can also work with other medical professionals to integrate a treatment plan to resolve musculoskeletal problems.
