Anxious sleepers and people with memory difficulties are being advised to seek snoozing assistance through listening to different soundwaves.
With so many wellness trends being showcased on a daily basis across social media platforms, Online-Bedrooms.co.
This comes after research reveals 41% of Britons who sleep on average less than five hours per night report having problems falling asleep every night.
Although many have previously heard of white noise, the full spectrum of sounds is more complicated and has many colours, including white, pink and brown noise.
The colour noises depend on the intensity and distribution of energy and integrating these sleep-specific noises into night-time routines can be beneficial for people of all ages to help clear the mind, relax and drift into a deep sleep.
Nic Shacklock from Online-Bedrooms.co.uk said: “Many struggling with things like sleep and concentration find themselves feeling unproductive, sluggish and irritable throughout the day.
“There are lots of remedies for anxious sleepers including pillow mists, lavender sleep balm and weighted blankets – however those who haven’t yet found their relief might just find sleep sounds to be the key to a better night’s sleep and concentration throughout their day.
“This is why we are breaking down the differences between white, brown and pink noise.”
White noise – the highest tones
The steady hum of a fan, the hiss of untuned radio static or a humming air conditioner are all examples of white noise. Energy is equally distributed across the frequencies in white noise, which is what makes it different to pink and brown noise. White noise contains all the sound frequencies in the audible range, making the sound even and consistent. White noise can help to block out any loud external noises that stimulate the brain and disrupt sleep, which is why it is often recommended to those with insomnia or people who struggle with sleep due to living on a noisy street.
Pink noise – mid-deep tones
Pink noise is deeper than white noise, as the energy is not distributed equally across the sound frequencies. The energy is more intense at lower frequencies and is a softer alternative to those who struggle to listen to white noise. Rustling leaves, rainfall and wind are all examples of pink noise, which to the human ear sounds flat or ‘even’.
As well as blocking loud disruptive noises, pink noise has been linked to improving memory. Deep sleep is crucial for creating and consolidating memories, meaning those with fractured sleep cycles tend to experience a memory decline.
Brown noise – deep tones
Brown noise is the deepest in tones out of the three types of sound and presents as constant noises with minimal sound vibrations. Examples of brown noise include low roaring, thunder or strong waterfalls. While the audible differences between brown and white noise are relatively small, those who struggle with the tone of white or pink noise find brown noise to be less intense and easier to listen to.
Compared to white and pink, there has been little research around the impact of brown noise on sleep and concentration, but the sense of relaxation provided by the sound can be beneficial to those who struggle to listen to the intense tones of other noises to help mask other noises or help to stay concentrated on a task.
