Many people struggle to fall asleep without background noise. While some may find it soothing, others may have developed a psychological dependence on it. For some, the silence can be overwhelming, leading to anxiety and a racing mind. Background noise can also mask disturbing peak noises, such as traffic or a partner's snoring, and provide a distraction from anxious thoughts. However, the research on the effectiveness of white noise and continuous noise is limited, and there may be negative consequences, such as potential harm to the inner ear and disrupted sleep. Additionally, the relationship between noise during sleep and long-term health effects is unclear, with possible associations with high blood pressure, heart disease, and stroke.

What You'll Learn
Background noise can help to mask other disturbing noises
Background noise can be used to mask other disturbing noises that might otherwise keep you awake. This is known as auditory masking, and it can help to improve your sleep. For example, a constant, low noise in the background can block out peak noises such as traffic, noisy neighbours, or a partner's snoring.
Some people find that the silence gives too much space for their thoughts, and they start to ruminate or plan fake scenarios. Background noise can provide a distraction from these anxious thoughts, making it easier to relax and fall asleep.
While some people may prefer the sound of a fan or nature sounds, others might opt for a TV show or podcast. For instance, one person mentions that they "feel comforted" by the "dulcet tones of Michael Scott" from the US version of *The Office*. Another person describes how they used to fall asleep to the sound of their mother hosting a dinner party downstairs.
However, some experts caution that there is little evidence that white noise apps work, and they may even be detrimental. Professor Christian Cajochen, who heads the Centre for Chronobiology at the University of Basel, suggests that white noise is only beneficial in a noisy environment, such as for night shift workers who need to sleep during the day.

It can help to distract from anxious thoughts
Background noise can be a useful tool for those who struggle to sleep in silence. For some, the quiet darkness of the night has been a source of uneasiness since childhood. The silence may give too much space for anxious thoughts and fake scenarios to play out in one's head. As one individual puts it: "I get really anxious and, without [the TV on], I spend the whole night just reliving my day, panicking about everything I said or did."
The use of background noise can provide a sense of comfort and security for those who feel anxious in silence. It can act as a distraction from anxious thoughts and help prevent the mind from racing. This is known as auditory masking, where a constant, low noise in the background masks other sounds that might be heard at night, such as traffic or a partner's snoring.
While some people may find comfort in the silence, for those who struggle with it, background noise can provide a sense of familiarity and safety. For example, one person shares that they like hearing the hubbub of people talking without necessarily being a part of it. This preference for background noise may also be influenced by one's sleep history. If someone grew up in a household where there was always some form of background noise during bedtime, it may have become an ingrained part of their sleep routine.
It's important to note that while background noise can be helpful for some, it may not be the best solution for everyone. Some experts suggest that the main concern for those with poor sleep is a busy or racing mind, and that white noise may not effectively address this issue. Additionally, there may be potential ill effects of not allowing the auditory system to switch off overnight, as the inner ear remains active and generates metabolites that could be harmful.
If you find that your fear of silence is impacting your sleep and causing significant anxiety, it may be helpful to seek support or guidance from a professional.

A psychological dependence on sleeping with noise may develop
Some people feel that they need background noise to sleep because of the comfort it brings. It can be a continuation of a childhood habit, such as falling asleep to the sound of a parent hosting a dinner party downstairs. The noise provides a sense of security and comfort, blocking out the environmental noises that could startle them awake. It can also act as a cue, signalling to the brain that it is time to sleep.
For others, background noise may provide a distraction from anxious thoughts or worries that keep them awake. It can help to mask other disturbing noises, such as traffic or a partner's snoring, which could wake them up. By drowning out these peak noises, background noise can improve sleep quality.
Additionally, some people may find that their sleep history contributes to their need for noise. For example, someone who grew up in a noisy household with constant chatter and activity may find that silence is overwhelming when they are used to falling asleep in a stimulating environment.
While needing background noise to sleep is not unusual, feeling intense fear and anxiety at the thought of sleeping in silence may indicate an underlying issue. If you find that your need for noise is non-negotiable and distracts you from your inner dialogue, it may be a sign of a bigger problem, such as anxiety or a fear of being alone.

It may be a comfort thing, providing a sense of security
The need for noise while sleeping may be a comfort thing, providing a sense of security. For some, the quiet darkness of nighttime has been a source of uneasiness since childhood. The silence may give too much space for anxious thoughts and crazy fake scenarios. The quiet and the dark can make one feel that something bad will happen. However, as soon as some noise is added, one might feel comforted and secure.
For those who have grown up in a noisy household, silence while sleeping might be overwhelming. For instance, someone who grew up in a room-share with six other girls might have become so used to falling asleep in a room full of chatter that silence becomes overwhelming. The constant low noise in the background can mask other noises that might be heard at night, such as the house settling, horns honking outside, or pets running around the house.
Some people might have a psychological dependence on sleeping with noise. If one has put on background noise every night before bed, one might have developed a psychological dependence on it. When trying to sleep in silence, one might get anxious about not being able to sleep, and this anxiety keeps them up. This can even lead to insomnia. Putting on background noise may act as a cue, signaling to the brain that it is time to sleep, and without that cue, one might struggle to fall asleep.
The need for noise while sleeping may also be related to one's sleep history. For example, if one grew up in a house that always had some kind of white noise in the background during bedtime, it might have become an ingrained routine as one dozes off. A 2023 US News & World Report sleep survey found that more than one-third of adults listen to white noise as part of their bedtime routine.

Some people have a fear of silence, which can be linked to anxiety
Some people have a fear of silence, known as sedatephobia, which can be linked to anxiety. This phobia can cause people to feel agitated, anxious, and ill at ease. The fear of silence is often a learned behaviour, with many individuals growing up in environments where the television was always on, even when no one was watching. As a result, some people become uncomfortable when the background noise they are accustomed to is taken away.
For some, the silence gives too much space in their brain, and they find themselves planning fake scenarios or feeling like something bad will happen. The quiet can also be unsettling for those who live alone, as it can make them feel unsafe. In these cases, background noise can provide a sense of comfort and security.
Additionally, individuals with sedatephobia may also struggle to fall asleep without noise. They may rely on music, television, or sound machines to help them fall asleep. This can be attributed to the need for a "security blanket" of noise to block out the silence and provide a sense of comfort. However, it is important to note that the use of white noise apps and devices as sleep aids is controversial, as some studies suggest they may do more harm than good.
To overcome the fear of silence, individuals can start by gradually embracing short periods of quiet in their daily routines, such as turning off the television while washing the dishes or walking the dog without their phone. Mindfulness meditation and focused attention practices can also help individuals confront their fear of silence and develop comfort in silence. Seeking help from a therapist or support from loved ones can also provide relief and help individuals get to the root of their fear.

Frequently asked questions
Many people feel the same way, and it's not unusual to need some kind of background noise to fall asleep. For some, it's a way to block out other disturbing noises, like traffic or a partner's snoring. For others, it's a way to manage anxiety or stress, or to distract from anxious thoughts.
Noise can have a major impact on sleep. It can cause fragmented sleep, changing the time spent in each sleep stage. Environmental noise, like traffic, can increase light sleep and decrease deep sleep and REM sleep. Over time, this may result in long-term mental and physical health consequences, including high blood pressure, heart disease, weight gain, and certain types of cancer.
Background noise can improve your sleep quality by masking peak noises, like traffic or a snoring partner. It can also help manage stress and anxiety, providing a distraction from anxious thoughts. Some people find that background noise, especially familiar noises, can be soothing and comforting.
While background noise can be helpful, there is limited research on its long-term effects. Some studies suggest that it may do more harm than good, leading to more disrupted sleep and preventing the auditory system from fully switching off. Additionally, a psychological dependence on sleeping with noise can develop, making it difficult to sleep without it.
