Sound therapy, or sound healing, is sometimes also referred to as sound bathing because it is deeply immersive and all encompassing – a full body experience.

Science shows that sound vibrations exert powerful effects on the body, slowing down brain waves and aiding our bodies to be relaxed, sometimes reaching a dream-like state. Research also links listening to music to reduced stress levels and boosting the function of the immune system.

In the modern internet world there is an overwhelming amount of information; it can be hard to find health advice that you can trust, particularly as the main media channels are typically dominated with a single, orthodox narrative.

We always take an evidence-based approach, orientated towards a holistic and Personalised Health approach, and aim to provide you with actionable knowledge and tips to help you on your journey to optimal health.

In this article we’ll take a closer look at sound therapy, the difference between white, pink and brown noise, and the potential benefits for your health and wellbeing.

Sound therapy

There are different ways of experiencing sound therapy but typically it involves varying combinations of specialist instruments, music and sounds played in a therapeutic way. It is thought to exert positive effects on health and wellbeing both physiologically and psychologically, and is particularly effective when combined with mindfulness and self-reflection techniques.

Different, specialised frequencies of sound can be used to create a calming, restful atmosphere that promotes emotional release and healing. The sound vibrations impact the body’s tissues on a cellular level, causing cells to compress and relax alternately. This is thought to be stimulating to the tissue, aiding the improvement of metabolism and blood circulation, as well as improving muscle tension.

Research has also shown that sound therapy can exert a beneficial effect on alleviating symptoms of many chronic health conditions such as PTSD, anxiety, autistic spectrum disorders, tinnitus, and dementia.

In part, this is due to its ability to reduce levels of the stress hormone cortisol and so help alleviate symptoms of stress, as well as assist with lowering blood pressure, heart rate and cholesterol levels – and generally promoting relaxation, sleep quality and wellbeing.

The colour of sound – white, pink and brown noise

Exposure to coloured noises is trending. The difference between these types of noise comes down to frequency – they effectively work by emphasising different frequencies over others. What they all have in common is the ability to make other sounds less perceptible, effectively drowning out other sounds that can be distracting, and so exerting a calming effect on the brain and body.

  • White noise contains components from across the sound spectrum – think of it as all the frequencies combined together, typically creating a static like sound, and sometimes referred to as ‘broadband noise’. Research has shown that exposure to white noise can help soothe babies, as well as increase productivity, help alleviate symptoms of ADHD, and promote better sleep.
  • Pink noise is sometimes called ‘ambient noise’, and as with white noise, it also contains components from across the sound spectrum. It effectively is the same as white noise but the difference is that pink noise sounds lower pitched, as it has reduced higher frequencies. This means it contains lower sound waves and deeper sounds, and is therefore thought to be gentler, and so more relaxing than white noise. Studies suggest it can help to improve sleep as well as boost memory and cognitive abilities.
  • Brown noise is also known as ‘red noise’ and is a deeper, more bass-like sound, than white or pink noise, because it has lowered high frequencies. It can be described as a ‘rougher’ sound than white and pink noise, but again exerts positive health benefits, including relaxation and improved focus and soothing of tinnitus, as well as promotion of improved sleep.

The vagus nerve

This is the body longest cranial nerve, running from the brain to the abdominal organs. It interacts with many different parts of the body, and because of this it is sometimes referred to as ‘the wandering nerve’.

It is of vital importance to a myriad of bodily functions, aiding the regulation of heart rate, breathing, digestion and the immune system, as well as exerting an effect on emotions and mood, through its ability to regulate the body’s parasympathetic nervous system.

Stimulating the vagus nerve can induce a calming effect and sound therapy can help to initiate this stimulation by triggering a parasympathetic response that soothes the body and in turn the mind. Similarly, singing or humming is another way of stimulating the vagus nerve.

Takeaway

Everyone will respond in an individual way to different frequencies, so if you are interested in finding more about the benefits of sound therapy, it is advisable to do some research and experiment with listening to different types of noise to see what resonates with you positively.
