See and Hear How You Control Your Body’s Reaction to Stress

This device correlates the relationship of stress to galvanic skin resistance (GSR), which is controlled by the sympathetic nervous system. It translates tiny tension-related changes in your skin pores into a measurable signal that can be seen on a meter, or heard with earphones (both included). This system also allows you to visualize the changes in skin temperature that occur as a result of stress. It comes with the GSR monitor, temperature sensor, dual sensitivity meter of visual feedback, biofeedback relaxation training cassette, one 9 V battery, and an instruction booklet, all packed in a carrying case. Size of monitor: 4" x 3" x 1 3/4".
