Many people find it difficult to sleep in silence. Some people may even experience fear and anxiety at the thought of sleeping without background noise. This could be due to a variety of reasons, such as the need to mask disturbing peak noises, anxiety, or a psychological dependence on noise. For some, it may be linked to an underlying condition like general anxiety disorder (GAD), obsessive-compulsive disorder (OCD), or a phobia. Background noise can also provide a sense of comfort and security, helping to quiet a stressed-out internal monologue. White noise, in particular, is a popular choice for those who need background noise to sleep, as it can effectively block out environmental noises that could cause a person to startle awake or keep them awake.

White noise can help mask other noises, like traffic or a snoring partner
White noise can be an effective tool to mask other noises that may disrupt your sleep, such as traffic, a snoring partner, or noisy neighbours. This is known as "auditory masking", and it can improve the quality of your sleep by preventing you from being awakened by these peak noises.
White noise is created by layering multiple sound frequencies simultaneously, resulting in a consistent, ambient noise that helps to drown out other sounds. It can be produced by a white noise machine, a fan, or even a familiar TV show playing in the background. Some people also find comfort in nature sounds or calming music, which can be used as an alternative to traditional white noise.
The use of white noise to improve sleep may be especially beneficial for light sleepers or those who live in noisy environments. For example, a 2021 study found that participants in noisy New York City fell asleep faster and woke up less frequently when they used a white noise machine. Similarly, a 2023 U.S. News & World Report sleep survey revealed that over one-third of adults include white noise as part of their bedtime routine.
However, it is important to note that there is not enough evidence to determine whether sleeping with noise playing all night is safe or harmful to your health. As such, it is recommended to use a timer when falling asleep with white noise and to keep the volume as low as possible. Noises above 47 decibels may disturb sleep and impact your sleep quality.
Ultimately, the preference for white noise or silence when sleeping may vary from person to person. While some people find comfort in the constant, low noise of white noise, others may prefer the quiet darkness of the night. If you find that your need for white noise is causing you impairment or distress, or if you experience intense anxiety when unable to sleep with white noise, it may be helpful to consult a professional for guidance.

It can block out environmental sounds that might startle you awake
White noise can be an effective tool to block out environmental sounds that might otherwise startle you awake. For instance, noises such as traffic, a partner's snoring, or a neighbour's TV can be masked by the consistent, low noise of white noise machines, fans, or air conditioners. This is known as "auditory masking", and it can improve the quality of your sleep by preventing you from being disturbed by peak noises.
White noise is produced by layering multiple sound frequencies at the same time, resulting in a quiet, neutral noise such as a humming fan or calming nature sounds. It can be customised to your preferences, with options to download a white noise app or sound file to your smartphone or tablet, or to purchase a white noise machine.
The use of white noise to improve sleep may be especially beneficial for light sleepers or those who experience anxiety when trying to sleep in silence. By providing a distraction from anxious thoughts and blocking out unexpected sounds, white noise can help you fall asleep faster and wake up less often throughout the night.
However, it is important to note that there is not enough evidence to determine whether sleeping with sound playing all night is safe or damaging to your health. As such, it is recommended to use background noise wisely, opting for lower volumes and considering the use of a timer to limit noise exposure throughout the night.

Some people find silence uncomfortable, leading to anxiety and negative thoughts
For some, the need for noise at night may be linked to an underlying condition, such as general anxiety disorder (GAD), obsessive-compulsive disorder (OCD), or a phobia. GAD is characterised by severe and ongoing worry, which can interfere with one's quality of life and daily activities. In such cases, the quiet and darkness of bedtime can trigger intense anxiety. Similarly, phobias are intense, clinically diagnosable fears that can induce extreme panic when faced with the object or situation of fear. If the need for noise at night brings impairment, distress, or intense anxiety when forgotten (e.g., when travelling without a white noise machine), it may be beneficial to seek professional help to address any potential underlying causes.
The use of background noise can be a helpful tool for those who struggle with silence. White noise, in particular, is a popular choice, as it can effectively mask other noises that may disturb sleep. This is known as auditory masking, and it can improve sleep quality by blocking out peak noises, such as traffic, noisy neighbours, or a partner's snoring. Consistent background noise can also help to drown out normal everyday environmental noises, preventing people from being startled awake or kept awake during the night.
Additionally, the use of background noise can be attributed to personal preference and sleep history. For example, some people may have grown up in households where white noise was always present during bedtime, and thus it has become an ingrained part of their sleep routine. The comfort and security provided by familiar sounds can aid in relaxation and improve sleep. However, it is important to note that there is not enough evidence to determine whether sleeping with noise playing all night is safe or damaging to one's health. As such, it is recommended to use background noise wisely, such as by playing it on a timer and at a low volume.

It may be linked to underlying conditions like GAD, OCD, or phobias
Difficulty sleeping in silence can be linked to underlying conditions like Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), or phobias. GAD is characterised by severe and ongoing worry, with heightened levels of anxiety and stress. People with GAD may use noise as a distraction to silence their fears and stressors, as their nervous system is already on high alert.
OCD, which is marked by obsessions and compulsions, can also be a reason for needing noise to sleep. The noise may be used to block out intrusive thoughts, acting as a coping mechanism to occupy the mind. People with OCD may also engage in compulsive behaviours or repetitive actions related to sleep, such as clock-checking or reassurance thoughts.
Additionally, specific phobias, such as somniphobia, the fear of sleep, or phonophobia, the fear of loud noises, may also be factors. If the need for noise at night causes impairment, distress, or intense anxiety, it may be beneficial to consult a professional to address any underlying fears or conditions.

White noise can be comforting, like hearing hubbub without being part of it
White noise can be comforting to those who struggle to sleep in silence. For some, the silence gives "too much space in my brain", leading to anxious thoughts and fake scenarios. The presence of white noise in the background can help to block out any intrusive thoughts and provide a level of comfort and security.
For others, it is about blocking out other environmental noises that could cause a person to startle awake or keep them awake. White noise can mask other sounds, such as traffic, a partner's snoring, or a neighbour's TV, and create a more consistent and soothing soundscape. It can also help to drown out the sounds of a busy environment, such as a city, and allow people to get more sleep than they would without it.
The use of white noise to aid sleep may also be linked to personal preference and sleep history. For example, someone who grew up in a household where there was always background noise during bedtime may continue to associate that noise with sleep. This could include the sound of a fan, the TV, or a white noise machine.
White noise can also be comforting as it provides a sense of hubbub without requiring active participation. This can be likened to the comfort of hearing the sounds of a dinner party downstairs while falling asleep as a child.
While white noise can be comforting and aid sleep, it is important to be mindful of the volume and duration of the noise. Noises above 47 decibels may disturb sleep, and there is some research to suggest that exposure to noise during sleep can have immediate and short-term effects, as well as potential long-term mental and physical consequences. Therefore, it may be advisable to use a timer when sleeping with white noise to ensure it doesn't play all night.
