Psychoneuroimmunology and Resiliency

Psychoneuroimmunology, otherwise known as PNI, is the blend of physiology and immunology with behavior (Freeman, 2009).  Let's look at PNI through an illustration.  Consider the idea of stress affecting a person’s behaviors as well as simultaneously affecting the neural signals being sent through the body and brain.  Over time, this stress could create pathways that will lead the body’s immune system to be compromised.  There is a connection between the mind, body, and behaviors that PNI sets out to study.  According to Freeman (2009), this is a relatively new specialization and subsequently an area that requires more attention.  One area that has received significant attention is the idea of early life stress. 

Early life development occurs in everyone therefore it is very important for factors involved to help invoke positive development.  Unfortunately, early life stress has become a negative factor in a young person’s development.  Several studies (e.g. Ehlert, 2013; Fagundes, Glaser, & Kiecolt-Glaser, J. K. 2013; Johnson, Riley, Granger, & Riis, J. 2013; Miller & Chen, 2013) have highlighted the negative effect that early life stress has on the immune system and ultimately health in later life.

There is another subset of research (e.g. Chawla, Keena, Pevec, & Stanley, E. 2013; Cicchetti, 2013) that focuses less on the negative effect of stress on immune system and health issues and more on the resiliency of some in early life to come through seemingly terrible situations. 

One look (Chawla et al., 2013) at resiliency focused on an outdoor or “green” effect on young people.  This study assessed the idea of school children having an outdoor space that would ideally help them to release stress in a natural manner.  The research builds upon the idea that being around natural settings (i.e. trees, grass) allows for a healthier environment than say for instance an urban area.  In this qualitative study, numerous natural environments were used.  Between interviews and observations, it was determined that the green effect was a positive one.  The research associates the results with others who have studied living near natural habitats and showed lower levels of depression, ADHD, and better abilities of dealing with stress. 

The importance of studying early life stress seems to be paramount.  In a world that is struggling to finance health care for adults, the implications for better understanding early life situations is a tremendous responsibility.  Part of this is to understand the mystery of resiliency.  Resiliency is a very important discussion (see Goldstein & Brooks, 2013).  To not look into the factors of resiliency in the broader scope of early life issues is missing a large piece of the puzzle.
