Effects of Sound-based Meditative Healing Method on Stress, Tension, Cortisol’s Level & Blood Pressure: A Randomised Controlled Trial

Psychological stress, depression, and tension are currently becoming very common in this developed world. Fighting these conditions has become a struggle for every individual. Introducing integrative traditional medicinal techniques such as sound-based meditations, especially from various forms of singing bowls, gongs and pre-recorded sound frequencies such as solfeggio frequencies (mainly 528 Hz), was found to be beneficial significantly. This study investigated the effects of sound-based meditation for four weeks, 60 minutes every day, on the stress, anxiety, tension, mood, cortisol levels, blood pressure and spiritual well-being of participants. One hundred men and women (mean age: 45 years) were included. They are divided into two groups, i.e., the control group (n=50) undergoes meditation without received a sham sound intervention , simulating the sound-based setup without therapeutic frequencies, and the experimental group (n=50) undergoes the intervention of all forms of sound-based meditation techniques. The observations revealed that the participants in the control group had no evidence of positive changes in the levels of stress , anxiety, tension, cortisol, mood, or blood pressure (p>0.05), with no significant changes remaining. The experimental group reported significant positive changes in stress, anxiety, tension, cortisol, and blood parameters after the sound-based meditation intervention (p<0.001) . This can be used in all stressful environments, such as meditation centres, counselling centres, companies, industries, and educational institutions, to bring back a harmonious and calm mind-set among the people.
