How Does White Noise Help Sleep?

A good night’s sleep does not come naturally to everyone. If you’re a light sleeper, it may appear that no matter how hard you try, something constantly keeps you tossing and turning all night.

Whether it’s a neighbor’s dog howling, your spouse snoring, or an unexplained “bump in the night,” you keep waking up, attempting to push yourself back to sleep before your alarm goes off for work. [1]

You may have contemplated purchasing a white noise machine to aid in your sleep. To assist you in making the best selection, we answered the question “How can white-noise help you sleep?” and included some additional helpful hints for getting a good night’s sleep.

White Noise

White noise contains all of the audible sound frequencies at equal intensity or amplitude, much as white light is generated when all of the colours in the rainbow are present.

Even if you’ve never heard of a white noise machine, you’re probably familiar with the sound since white noise sounds just like having your radio tuned halfway between stations.

White Noise to Help Sleep


Many individuals use white noise devices to help them sleep, but how precisely can white noise help you sleep? The explanation is that the sound produced by white noise generators serves as a mask for other disturbances that may wake you up in the middle of the night or prevent you from falling asleep in the first place.

While you sleep, your ears continue to catch up on sounds around you, and if they are unexpected or loud, your ears operate as your body’s alarm system, alerting you to possible threats. Using a loud, perhaps unpleasant noise to help you sleep may appear odd at first.

White noise, on the other hand, acts as a form of anti-noise, distracting your brain from other stimuli. At the same time, don’t give it anything specific to focus on right now. Some find them annoying, while others swear by them.

To use light as an example once more, a flashlight in the dark will attract your attention and be quite visible. In a bright environment, you will barely be able to determine whether that same flashlight is turned on.

White noise apps for your phone are also available, but you’re better off investing in a machine that will play white noise all night. An app may help you sleep, but if it turns off after an hour, the abrupt shift in your aural environment may wake you up again.

Other Types of White Noise

Other steady, unchanging background sounds are frequently referred to as “white noise.” Natural noises such as rainfall, crickets, and the ocean are frequently used as sleeping soundtracks.

Noise created by machinery such as an air conditioner and a fan, as well as ambient noises such as crowds and campfires, can also help some individuals sleep.

Because they do not span the whole audio frequency range, none of them will be as effective at filtering out other noises as true white noise.

Top Sleeping Recommendations


Attempt to sleep and wake up at consistent or comparable times each day. Your body will respond well to a schedule and will begin to manufacture melatonin around your bedtime each evening.

This also applies to weekends! Your body will get so acclimated to the habit that you will no longer require an alarm clock.

Caffeine consumption should be reduced:

Reduce your everyday caffeine use. In the afternoon, switch to decaf coffee and tea since caffeine is a stimulant that can persist in your system for up to eight hours.

Avoid using screens before bed:

The blue light generated by your TV, phone, and computer screen fools your brain into believing it’s daytime. Avoid all forms of displays for a couple of hours before bedtime if possible. Instead, listen to music or read a book or magazine.

Consider using melatonin supplements:

Maybe your body isn’t making enough melatonin to help you fall and stay asleep. Melatonin pills are a well-known sleep aid. It is suggested to take one to five grammes 30 to 60 minutes before night, but always see your doctor first.

Conclusion – How Does White Noise Help Sleep?

Sleeping properly is just as crucial for your health as eating well and exercising regularly. Poor sleep, in fact, may have a severe impact on your brain function, hormones, and weight, among other things.

Many people find that white noise machines help them sleep at night by concealing sounds from their surroundings that might otherwise wake them up. If there is any possibility that a white noise machine will help you sleep better, it is absolutely worth a shot.
