A method for providing a therapeutic benefit to a person is disclosed which includes a processor executes a first function to determine a physiological parameter from one or more physiological sensors positioned on the person and then the processor executes a second function to determine at least one of a second physiological parameter from the one or more physiological sensors or an environmental parameter from one or more environmental sensor associated with a location of the person. Next, the processor uses either the first and second physiological parameters or the first physiological parameter and the environmental parameter to determine whether to apply bi-lateral stimulation to the person； activating first and second stimulators positioned bi-laterally on the person to initiate bi-lateral stimulation for a therapeutically effective time period when the processor determines to apply bi-lateral stimulation.
