Pink Noise for Better Sleep

The color of noise is determined by the energy distribution of the sound signal across various frequencies. While White Noise consists of all audible frequencies at equal energy, Pink Noise's energy is concentrated at lower frequencies, creating a deeper and more pleasant sound.

It's no wonder Pink Noise is gaining popularity. Many people have discovered its ability to help them relax and achieve the restful sleep they need.

Nature is full of Pink Noise, including leaves rustling in trees, steady soft rain or a light breeze, to name just a few.

To the human ear, Pink Noise sounds even, and because it has the same tones in nature that we find pleasant, many people find it very relaxing as well.

In fact, customers often tell us they would still use Hestinn's Pink Noise to fall asleep even if their partner stopped snoring tomorrow. Yes, many people have purchased Hestinnto drown out their partner's snoring and are now getting the best sleep of their life!

Hestinn has developed a proprietary and specially designed Pink Noise. It is a modified, or shaped, Pink Noise, developed by a PhD in psychoacoustics. How did he do it?

Because Hestinn was invented to mask snoring, he went into his sound studio, found a bunch of snoring sounds on YouTube and played them at the same time. While all this snoring was playing he went to work to modify the Pink Noise to mask the snoring more effectively.

Some of the higher tones were decreased and some of the lower tones were increased. This shaped sound masks snoring and other sleep disrupting noises very effectively.

A study published in the Journal of Theoretical Biology found that steady Pink Noise reduces brain waves, increasing stable sleep.

Research by Northwestern University and Frontiers in Human Neuroscience both concluded that exposure to Pink Noise during sleep leads to an increase in deep sleep, which is associated with physical restoration and memory consolidation.

The NIH study Pink Noise: Effect on Complexity Synchronization of Brain Activity and Sleep Consolidation" revealed that steady Pink Noise exposure significantly reduces brain wave complexity. This results in more stable sleep and, ultimately, improved sleep quality.

Subsequent studies also showed an improvement in sleep quality with Pink Noise. Participants reported it was easier to fall asleep, they slept deeper, and they felt more rested upon waking.

Researchers reported participants found it easier to fall asleep, slept deeper, and reported feeling more rested upon waking.

Harvard & Yale trained psychiatrist, Suruchi Chandra, MD, delves deeper into the science behind the extensive benefits of pink noise for sleep, cognition, and overall well-being. Here, she explains why emerging research on Pink Noise is more promising than White Noise when it comes to brain health:

1.  It can sound more soothing and be more calming for the nervous system.
2.  Our brain cells communicate through brain waves that follow a pattern similar to Pink Noise. And because pink noise can match our brain wave patterns, it may be more stabilizing for the brain.
3.  As our brains age, they produce more white noise and less pink noise. In other words, pink noise may be associated with younger and healthier brains.
4.  During sleep, our brains produce slower brain waves that allow the body and brain to enter a state of rest and restoration. There are fewer of the faster brain waves that occur during periods of focus and concentration...

Doctor Chandra’s findings indicate that:

• Pink noise appears to amplify the power of the slower brain waves during deep sleep.
• And, when administered at night, it may help people fall asleep faster and get deeper, less fragmented sleep.

Calming Effect on the Brain

Pink Noise helps you relax and unwind, making it easier to fall asleep.

Uninterrupted Sleep

Pink Noise masks disruptive background sounds, reducing the likelihood of waking up during the night.

Stabilized Sleep Patterns

Pink Noise aids in stabilizing sleep patterns, helping you fall asleep and stay asleep for more continuous and restorative sleep.

Promotes Longer Periods of Deep Sleep

The balanced spectrum of Pink Noise has been reported to promote longer periods of slow-wave or deep sleep, crucial for memory consolidation and overall cognitive function.
