Aligning your brainwaves to a certain frequency can cause a physiological reaction. Physiological reactions are often stress-related, such as an increased heart rate. With sound therapy, your body’s physiological response is positive. You release nitric oxide, a molecule responsible for expanding blood vessels, increasing blood flow and influencing pain signals.
The key to sound therapy relaxation is calming your mind and body, which allows entrainment to occur. Many people opt to lay down and close their eyes, for example, during a session. A less natural approach to sound therapy is ultrasounds, which also create vibrations and are used for treatment on occasion.
Sound therapy isn’t a cure, but it’s a healing technique. For some conditions, like chronic pain, your focus isn’t on curing it, but managing it. Easing your emotions is another benefit of the alternative treatment. Cancer patients, for example, have used it to express their fears and other emotions.
Practitioners of sound therapy also note that loud environments, like the city, can shift our relationship with sound. Instead of therapeutic, it’s stressful. Sound therapy resets that relationship and helps you become a better listener and more aware of what you’re hearing. So, instead of focusing on the jackhammer outside your building, for example, you hone in on other sounds, like the tiny chimes on your desk.
