Have you ever found yourself drifting off to sleep to the sound of a washing machine or a vacuum cleaner? You're not alone. White noise, a type of noise that contains all audible frequencies at the same intensity, has been shown to have a profound impact on our ability to fall asleep and stay asleep. In this blog, we'll explore the science behind white noise and why it's become a popular tool for improving sleep quality.
What is White Noise?
White noise is a type of noise that is characterized by its flat power spectral density, meaning that it contains all audible frequencies at the same intensity. This type of noise is often compared to the sound of static on a television or radio. White noise can be created by a variety of sources, including washing machines, vacuum cleaners, fans, and even specialized white noise machines.

How Does White Noise Affect Sleep?
Research has shown that white noise can have a significant impact on our ability to fall asleep and stay asleep. One study found that white noise reduced sleep latency (the time it takes to fall asleep) by 38% and improved sleep quality by 25%. Another study found that white noise reduced symptoms of insomnia and improved sleep quality in patients with chronic pain.
So, why does white noise have this effect on sleep? There are several theories:
-
Masking background noise: White noise can help to mask background noises that might be disrupting sleep, such as traffic or snoring.
-
Creating a constant sleep environment: White noise can create a constant sleep environment, which can help to regulate the body's internal clock and improve sleep quality.
-
Reducing stress and anxiety: White noise can have a calming effect on the mind and body, reducing stress and anxiety that might be interfering with sleep.
