“…Positive valenced emotions including experimentally-induced positive mood (Akins et al, 1983;Bruehl et al, 1993;Cogan et al, 1987;Weisenberg et al, 1998;Zelman et al, 1991;Zillmann et al, 1996), sexual excitation (Komisaruk and Whipple, 1986;Meagher et al, 2001;Rhudy et al, 2008), and relaxation (Cogan et al, 1987;Westcott and Horan, 1977) consistently lead to reduced pain/nociception. However, the degree of inhibition is determined by the intensity of the emotional state (as assessed by arousal level), with more intense positive emotions (i.e., sexual excitement) eliciting the greatest inhibition (Komisaruk and Whipple, 1986;Rhudy et al, 2008).…”
