Short term stress enhances immune function. Sustained stress suppresses immune function. The more stress, the fewer antibodies you will produce. Both kinds of immunity (cell mediated and humoral immunity) are affected by unrelenting stress, which means that you’ll be more likely to be infected by viruses, (also those linked to cancer), bacteria, fungi and parasites. You’ll also be more sensitive to environmental toxins, electromagnetic emanations from high tension electrical cables, and pollution.
The link between stress and immune function is far reaching, explaining the effect stress has on disorders ranging from the common cold, autoimmune diseases (such as multiple sclerosis, systemic lupus erythematosis, rumatoid arthritis, ulcerative colitis, Crohn’s disease) to HIV/Aids, through to cancer.
