Sleep is the cornerstone of our overall wellbeing; without quality sleep we can struggle with other aspects of our lives such as our physical and mental health. White noise machines are increasingly becoming a popular solution for improving sleep, helping to block out annoying sounds, consistent background noise, and creating a soothing environment for slumber.
White noise machines work by masking disruptive sounds; it’s an ‘effective acoustical shield’ that helps to reduce sound levels that could cause sleep problems. The ‘white noise’ is a type of soothing, evenly distributed sound and can drown out any outside distractions, making it easier for sleepers to reach deep sleep and get the restful night they need.
To explore the effectiveness of white noise machines in enhancing sleep, let’s take a look at the research.
White Noise Machine Research: Sleep Studies
Research published in the medical journal ‘Sleep Science’ looked into the effects of white noise on sleep quality and found that after two months, sleepers using white noise machines to block out disruptive noises reported improved sleep quality compared to those exposed to unpredictable sudden noises. The study concluded that white noise machines were effective in reducing sudden noises and thereby could positively impact sleep.
Another study conducted at the Riken Brain Science Institute in Japan showed that white noise machines immeasurably improved sleep disturbances in children with ADHD and autism. The study concluded that white noise could be a simple and inexpensive way of helping those struggling with sleep to improve the quality of their nights.
The Benefits of White Noise Machines
As well as blocking out sudden noises, white noise machines can help to create a more serene environment — and quality sleep environment — with a variety of different “white” noises to choose from, such as rain, waves crashing onto the shore, the sound of a gentle stream, or a fan. The calming effect and consistently of the white noise makes sleepers feel safe and secure, allowing them to drift off into deep sleep more quickly.
White noise machines are also particularly advantageous for children. 57% of sleep doctors now believe that white noise can be a very beneficial tool for helping kids to relax and fall asleep. Using a white noise machine to cover outside background noise, like a noisy neighbour, or traffic sounds, can make drifting off easier for restless children.
White noise machines are not only cost-effective but the sound they create is consistent and soothing. They mask common noises of the nighttime that can interfere with sleep, such as construction traffic, cars honking or dogs barking, and create a ‘calm and stylish atmosphere’, allowing us to reach deep sleep and wake up feeling well refreshed.
The Drawbacks of White Noise Machines
- Some people find that the sound of white noise can interrupt their sleep, rather than enhance it.
- White noise machines don’t directly treat sleep disorders.
- Long-term use of white noise machines could be damaging to hearing.
- White noise machines don’t address the underlying cause of sleep disorders – they simply mask the noise.
Final Thoughts
White noise machines can be a useful aid for those who struggle to reach deep sleep because of disruptive noises, children with sleep onset disorders, and those looking for methods to reduce environmental noise. However, it’s important to bear in mind that white noise machines offer only a temporary solution and that if users suffer from regular sleep disturbances or chronic sleep disruption, it’s always best to consult a doctor or sleep specialist.
