How sound can affect the body
Sound therapy uses low frequencies that fall in the alpha-theta-gamma-delta range, which corresponds to the brainwave frequencies that vibrate in the lower range
Sound Therapy has been used for treatment of chronic pain, anxiety, stress reduction, improved sleep quality, improved circulation and wound recovery and to reduce ‘brain fog’.
The brain instructs the body through electrical frequency stimuli. Sound therapy uses low frequencies that fall in the alpha-theta-gamma-delta range, which corresponds to the brainwave frequencies that vibrate in the lower range.

Lower frequency brain waves can also stimulate the release of nitric oxide, which signals smooth muscles to relax, so our blood vessels dilate and increase blood flow. Release of nitric oxide positively affects pain transmission and control, which some scientists believe helps to modify our relationship to pain.
In a 2015 study of patients suffering with fibromyalgia, (conducted by the University of Toronto) low-frequency sound stimulation was delivered twice a week for five weeks. The medication dose was reduced in about 74% of patients and completely discontinued in 26%. A majority of these patients were able to significantly increase the amount of time they spent sitting and standing without pain.
