1. An apparatus configured to generate and apply mechanical stimuli to skin of a user for regulating a physiological process comprising: a housing having a first surface for placement against the skin; an electro-mechanical actuator disposed within the housing and configured to generate and apply the mechanical stimuli to the skin; wherein the mechanical stimuli comprise ultra-low frequency stimuli that have a frequency between about 2 Hz (two stimuli per second) to about 0.1 Hz (one stimulus every 10 seconds), and wherein the mechanical stimuli have sufficient energy so as to engage skin sensory receptors that are configured to convey signals to the nervous system where the stimuli are at least one of consciously perceived and subliminally perceived.
