Abstract
Depression is a disease that has spread throughout modern society (a 2008 survey reported that approximately 120 million people worldwide suffer from depression). Persons with the disease are prone to feelings of anxiety. One cause of depression is thought to be an insufficient amount of serotonin in the body. We measured the concentration of serotonin in the blood before, immediately after, and 30 minutes after application of sonic vibration energy to determine if a change in serotonin concentration occurred. Results showed a change in the concentration of serotonin in the blood: average values (n7) were 200.01ng/mL before, 191.13ng/mL immediately after, and 204.47ng/mL 30 minutes after application of sonic vibration energy. In contrast to the view of modern humans that they become happy as a result of acquiring things that exist outside of themselves, our experiment results suggest the unexplored possibility that sonic vibration may be useful as a method of producing spontaneous happiness from within.
