Hypervigilance is a hallmark feature of trauma.
It means: hyper = excessive; vigilance = alert, awake, watchful.
This heightened state of awareness is part of our fight, flight or freeze response, resulting in a state of excess awareness.
If you've experienced trauma, then you're likely aware that you're always unconsciously on guard, scanning the environment for cues, signs, or situations, that signify a threat or potential danger. It's very hard to turn to off. This is your brain and your nervous system's best attempt to prevent future traumas.
The chronic hypervigilance is from an overactive amygdala (the emotional brain) and an underactive prefrontal cortex (the rational brain). The prefrontal cortex is the part of our brain that is responsible for regulating our emotions and reactions. It does offline when we are triggered, and without it, we get hijacked by our emotions.
What's happening is that our amygdala acts like the fire alarm in our brain. After a traumatic experience, it is swift to sound off the alarm at anything remotely reminiscent of the past (this is the smoke).
For example, say you were bullied a child. Now, as an adult, you're walking by a park, and you see a group of teens sitting around and laughing. Your mind may go into a hypervigilant mode, thinking they are laughing at you. Your brain and body are trying to protect you from more abuse.
Your heart rate increases. You might start to sweat and feel an overwhelming emotional response like sadness, insecurity or even anger. Your body is reminded of the trauma and goes into overdrive. The brain is always prepared for a fight, flight or freeze response. It is well-intentioned, but your survival mechanism might not be needed in this situation.
There are many ways to calm your amygdala. One way is to try yesterday's exercise on my feed.
Can you relate to an overactive amygdala?
