“…73 A reduction of circulating cortisol levels will likely have beneficial effects on arterial function and blood pressure control via inhibition of the hypothalamic-pituitary-adrenal axis. 74 In relation to the immunological system, listening to relaxing music can modulate the immune system through reductions in proinflammatory signals, associated with increased IgA and IgG levels 72,75,76 ; reduce the plasma levels of interleukins −4, −6, −10, −13, and tumor necrosis factor 61,62,77 ; increase natural killer cells 78 and CD8+ T cell expression 79,80 ; and decrease circulating histamine levels. 81 At the level of cognition, relaxing music positively influences perceptual information, declarative memory learning, memory recall and motor learning, 82 and may improve verbal learning and memory through its influence over the chunking mechanism and perceptual information processing.…”
