Effects of passive hyperthermia versus exercise-induced hyperthermia on immune responses: hormonal implications.

Abstract

Catecholamines play a major role in the mobilization of immunocompetent cells and the production of IL-10 during exercise. Prolactin and catecholamines have adverse role on the immune response, whereas cortisol exerts similar effects during both trials. The consequence could be a protection against inflammatory overshooting.
