When faced with frightening or overwhelming events, our brains reorganize. Your brain's alarm activated and this updated your mind's chain of command. The logical, thinking areas took a backseat. And the automatic and reactive survival regions got promoted to Team Lead. Their first memo to your system was that danger can lurk anywhere. You always have to be one step ahead.
The new company slogan is simple: “It’s better to be safe, than sorry.” Hearing every harmless noise is distracting. But, it makes you less vulnerable to potential threats. And it’s safer to be tired than miss signs of danger while asleep. These strategies are helpful adaptations in the short term. They increased your sense of safety just enough to keep you moving forward in the aftermath of trauma.
This promotion often lasts a few weeks. When the logical parts of your brain resume their executive role, they'll send out an updated memo. Once you get the all-clear, your system can return to its previous functioning. When updated within the month, we call this Acute Stress Disorder (ASD).
If high energy levels continue and this help is not required, symptoms will be created instead. This is why insomnia, anxiety, panic attacks, excessive anger and irritability are common after trauma. If symptoms persist past four weeks, a medical professional may assess you for Post-Traumatic Stress Disorder (PTSD). An assessment and diagnosis is not needed unless this feels important to you.
