Hello Kathleen,
The stress reaction, with its 'soup' of hormones, prepares the body for action. It activates quickly, bringing a burst of adrenaline for a fast response to stressor. The startle response happens in 100 milliseconds! If this quick surge doesn't resolve the stress, cortisol is released.
Stress reactivity that is chronic results in the sustained presence of too much cortisol and keeps the body and mind in its vigilance posture, and here's a new understanding from Poyvagal Theoey: the pre-frontal cortex doesn't come along. Simply put, we can't think clearly or creatively in a stress state, because the body's natural reaction contracts all processes into survival readiness.
Ever feel like you've forgotten how to add 2 plus 2?
