The physical effects of a negative state of mind are undeniable. The link between stress and high blood pressure, for example, is well established. So if a certain massage therapy makes you feel good then, in a sense, it is good. But surely this logic has its limits. For example, imagine if you suffered from anxiety attacks and someone gave you a sugar pill, telling you it was a tranquilizer. You took the pill and became calm.

In addition, breathing exercises may help you learn to more effectively oxygenate your blood during moments of peak stress. And at least integrative imagery acknowledges that it relies upon the power of your imagination for its effect.
