What is it about trauma that can have such a seductive pull? Can our bodies become addicted to trauma and its effect on us?
As horrific as the trauma exposures of war can be for many combat veterans, many long to return after they are safe at home. In his article “Why Soldiers Miss War,” Nolan Peterson explains that many combat veterans’ worst and best life experiences often occurred during combat (1).
Bessel van der Kolk also found many survivors of past trauma often went back to risky environments or abusive relationships even after making significant progress in therapy (2).
For those without trauma exposure, this desire may be hard to understand.
Once again, hormones likely are at play in this puzzling circumstance. One more hormone, in particular, might provide a further understanding of this seductive effect. In addition to the fight or flight hormone response of adrenaline and cortisol, endorphins also play an essential role in trauma exposure.
Endorphins are released during prolonged trauma exposure. Ironically, endorphins are often referred to as one of the “happy hormones.” While other “happy hormones” manipulate the body’s pleasure and reward system, endorphins act differently. Endorphins impact the body by blocking pain.
Feeling No Pain
In a study with combat veterans, van der Kolk found that even watching a violent movie for 15 minutes was enough to trigger the release of endorphins. Furthermore, this release of endorphins caused a 30% increase in pain tolerance levels in the participants (2).
Most shocking about this study was the number of endorphins that flooded the body in those 15 minutes. This endorphin flood was equivalent to injecting the body with 8 milligrams of morphine. For reference, the Mayo Clinic typically advises 1 – 5 milligrams of morphine be administered to those suffering from severe pain.
Addicted to Trauma
What causes the trauma addiction? Highly addictive opioids like morphine and heroin impact the body by mimicking the natural effects of endorphins. Fortunately, the endorphins released during trauma exposure do not typically saturate the brain’s pleasure and reward system to the level that occurs with opioids. With that said, endorphins are powerful natural pain relievers.
Endorphins can provide a very attractive release for those experiencing chronic physical or emotional pain. But unfortunately, when this release is the only escape from the pain, our bodies naturally crave more.
Another addictive chemical release that can occur during trauma exposure is dopamine. Unlike endorphins, this chemical directly impacts the body’s pleasure and reward system. Dopamine release is most common in trauma exposures that involve power or victory over others.
When combining endorphin’s pain-numbing effects, dopamine’s direct reward system impact, and the adrenaline rush, it becomes apparent why the body would crave this potent neurochemical cocktail. It’s understandable how someone may return to an environment that was a source of trauma.
Reviewing the research on the hormone responses in trauma exposures makes it apparent why certain behaviors occur, even in the workplace. Hopefully, you now better understand the challenges those with trauma exposures are experiencing. Trauma-informed leaders’ last step will be learning some practical tools to navigate these challenges.
In the following article, we will finally look at a trauma-informed leader’s tools and investigate ways to develop a trauma-informed culture in the workplace.
