Yerkes-Dodson law states that arousal works best when there is not too much of it. An Optimal level of arousal produces Optimal Performance.  Arousal is produced by Stimulation:  optimal stimulation is found within a narrow band of energy.

FACT: Our bodies are neurologically programmed to receive many forms of stimulation energy (e.g., food, light, sound, taste, touch, etc.) according to Yerkes-Dodson law, which describes the optimal level of Stimulation on an inverted U-curve.

For example: The right amount of coffee wakes us up and enables us to focus and get our work done.  Too much coffee causes us to become “wired” and stressed out.  The same principle applies to Vagus and Auricular Nerve Stimulation.

Years before it was verified by clinical research, we applied Yerkes-Dodson law to describe how stimulation arouses and empowers the parasympathetic nervous system (PNS) to counter-balance the excess inflammatory activity of the sympathetic nervous system (SNS).

Balance=Sweet-Spot=Optimal Stimulation.
