Abstract: | Activating the arterial baroreceptors in animals has been shown to blunt pain sensation and provide other forms of central
nervous system inhibition. This study tested the hypothesis that, among human subjects, a tonic increase in blood pressure
(BP) could be a learned response to environmental stressors among subjects in whom the baroreceptor inhibitory mechanism is
active. In a sample of 96 healthy, normotensive men and women, amount of pain-reduction produced by baroreceptor stimulation
predicted an increase in resting BP 20 months later: the increase was proportional to self-assessed daily life stress. Among
the subjects reporting the greatest amount of stress, the pain inhibition effect accounted for more than 80% of the BP variance.
These results support the hypothesis that the reduction in perceived stress produced by baroreceptor stimulation may reward
learned increases in BP.
