When people encounter threatening or high-stress situations, their bodies often react automatically with what’s known as the “fight or flight” response. This instinctive reaction has helped humans survive dangerous situations throughout history. Whether it’s facing a wild animal, experiencing a traumatic event, or navigating overwhelming stress, the brain and body shift into survival mode.
This automatic response is triggered by perceived threats to one’s safety—whether physical or psychological—and can result in intense fear, anxiety, and physiological changes. Over time, particularly in individuals who have experienced ongoing trauma or high-stress environments, these responses can become ingrained patterns of behavior.
To better understand these responses, let’s take a look at an example of how this could come to life. If you happen to find yourself face-to-face with a tiger, would you be more likely to take out a weapon and fight? Or would you lace up your best running shoes and run away – taking flight? Both reactions are considered normal for different types of people. However, there’s more to the story. In today’s society, it’s highly unlikely you will have to face a tiger, but traumatic events that involve actual or threatened death, serious injury, or threat to one’s physical or psychological well-being can sometimes lead to the development of traumatic disorders, such as post-traumatic stress disorder (PTSD). These events can overwhelm a person’s ability to cope, causing intense fear, helplessness, or horror.
