What is the flight response?
The flight response is the survival state that mobilises you to escape. When your nervous system reads a threat as something it can't safely confront but might be able to get away from, it floods you with the same activating energy as the fight response — but instead of pointing it at the danger, it points it at the exits.
In modern life, the threats are rarely things you can physically run from — a looming deadline, an awkward conversation, a feeling you don't want to feel. So the flight response adapts. The urge to flee becomes the urge to do: to stay busy, to keep moving, to fill every gap, to mentally race ahead. It's escape by motion rather than escape by distance, and it's one of the most socially rewarded survival states, because from the outside it often looks like being driven and productive.
