Possible mechanisms of the immunological effects of noise. We speculate that the influence of noise on the immune system may be correlated with neuroendocrine regulation such as the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic-adrenal-medullary (SAM) system (3, 8), as well as oxidative stress (10) and sleep disorder (3, 27) which partly reveal the direct connections between noise and immunity. Changes in several inflammatory factors and immune cells (7, 17) have also been found.
