When stress becomes chronic and mismanaged it is a detriment to our health and well-being. They discovered that reduction in adrenergic stress by use of β-blockers reverses immunosuppression and significantly improves responses to checkpoint inhibitor immunotherapy. However, in these situations, the survival aspects of the stress response, such as increased heart rate and immune activation, is not effective in resolving this threat.

The risk for all autoimmune diseases may not be equal: Stress can also dysregulate humoral and cellular immune responses to pathogens, increasing risk for infectious illnesses including influenza and the common cold (Glaser and Kiecolt-Glaser 2020). 2020), childhood adversity (Fagundes et al.

  • In addition, the immune system may sometimes break down and be unable to do its job.

In summary, stress can not only increase susceptibility to illness after exposure to infectious agents but also can inhibit antibody and virus-specific T cell responses to vaccines, permit reactivation of latent herpesviruses, and influence the progression of HIV-related disease. Improving the gut microbiota may be the key to building resistance to disease.
