Hand reflexology refers to pressure techniques applied to the hands, which interact as a part of the body’s nervous system, to create relaxation, improved circulation and other benefits of touch. Pressure sensors in the hands are part of the body’s fight-or-flight reflexive response. The perception of pressure by the hands taps into the reflex network that makes possible our every move. Reflexology provides an exercise of these pressure sensors and thus a conditioning of the internal organs to which they are tied.
