One AC is based on the theory of imbalance of dopamine to the nor-adrenaline/adrenaline complex. Dopamine is used first by the brain, then by the cardiovascular system and last by the sweating system. A reduction in dopamine below a certain level

allows the well-known vasoconstrictive properties of the nor-adrenaline/adrenaline complex to predominate and reduce the blood carrying capacity of the peripheral vascular system to a minimum, thereby reducing the ability of the sweat glands to function properly.
