How Exercise and Beta-Glucan Help the Immune System
It is thought that moderate exercise, such as speed walking, jogging, and aerobics may enhance your body's natural resistance to infection. This is due to that fact that this kind of physical activity activates the release of immunostimulatory factors, such as growth hormones, cytokines, and prolactin, which in turn activates various populations of immune cells.
Exercise sessions of moderate duration (under 60 minutes) have been associated with enhanced activity within the immune system. This applies to many different immune parameters, including oxidative metabolism, mactophage chemotaxis, and phagocytic activities, as well as increased natural killer cell activity. The nature of these cells' phagocytic, cytotoxic, and intracellular killing capacities constitutes and important part of the body's first line immune defense.
