The opponent-process theory of emotion

There is a remarkable psychological theory that explains the paradox of why so often our pleasures turn into problematic addictions and, conversely, why our stressful experiences frequently lead to sustained good feelings and even happiness. This under-appreciated theory was developed in the 1970s by behavioral psychologist Richard Solomon of the University of Pennsylvania. He published his theory and findings in 1980 in the journal American Psychologist, as a seminal paper, “The Opponent-Process Theory of Acquired Motivation: The Costs of Pleasure and the Benefits of Pain”. Solomon’s theory has been verified experimentally with animals and humans, and reflects a sophisticated understanding of the physiology of the nervous system. It provides a framework that has been used to explain behaviors and emotional experiences in areas as diverse as addiction, thrill-seeking, love, job satisfaction, and cravings for food or exercise.  I believe it can also explain the psychological benefits of cold showers that I have described in a separate post here, and why these benefits increase with time and repetition. I would urge followers of this blog to read Solomon’s paper, via the above hyperlink. It provides many important insights regarding how to effectively and reliably use challenge and stress to increase mental and emotional resilience, while maximizing your motivation and enjoyment in doing so. In this post, I will explore Solomon’s theory in some detail, and suggest some practical strategies for how to enhance pleasure and satisfaction in everyday activities, while avoiding the addictive side of pleasure.

Want to experience the benefits of hormesis very directly? Take a cold shower! And don’t just try it once, make it a habit and take cold showers daily.  I have been doing it daily for the past six months and am loving it!

As one form of hydrotherapy, the health benefits of cold water therapy are numerous.  Cold showers provide a gentle form of stress that leads to thermogenesis (internal generation of body heat), turning on the body’s adaptive repair systems to strengthen immunity, enhance pain and stress tolerance, and ward off depression, overcome chronic fatigue syndrome, and stimulate anti-tumor responses.

The physiology of stress

Do adaptations to stress exposure show up as changes in blood chemistry or heart function?  The answer appears to be “yes”.  In his Newsweek article “Lessons in Survival”, Ben Sherwood reported on a very interesting study of elite Army Airborne and Special Forces soldiers that probed the differences between those who could and could not endure an extremely stressful 19-day mock-prisoner-of-war camp.  The Resistance Training Laboratory, located at a secret location near Fort Bragg, North Carolina, subjected participants to sleep deprivation, blaring music, semi-starvation and — worst of all — intense interrogation techniques used by enemy forces during WWII, Korea and Vietnam.  ”The goal is to simulate hell on earth like the Hanoi Hilton in Vietnam or Al Qaeda’s torture chambers,” according to Sherwood.  In another test of mettle, at the Navy Diving and Salvage Training Center in Florida, trainee divers were put through stressful routines such as being thrown into a pool with their hands and feet bound, and underwater ocean swimming from 3 miles offshore to a target on shore.
