Folks, we’ve spent a couple of months talking about how your survival reflex works. Well, today we’re going to talk about what it actually does.
The fight/flight/freeze response is a basic survival reflex that is built into every animal. The part of your brain that powers is is called the amygdala (hey – wanna know how to pronounce that, so you can sound like a real geek? It’s uh-MIG-duh-luh. ) It’s a very primitive brain part, and we’re not consciously aware of what it does (ie., reflex is not a choice). Look at your thumbnail – that’s roughly the size and shape of your amygdala.
When the amygdala spots what it thinks to be a sign of danger, it goes into survival mode, and activates your fight/flight/freeze response.
Think of our friend that we talked about earlier - Dave the Zebra.
Although I’m sure this seems goofy to some of you, I won’t talk about Dave the soldier, Dave the veteran, or Dave the law enforcement officer. If I did, some of you would find it too painful. So instead, I’m going to talk about Dave the zebra. I want you to use him as a grounding skill: anytime the discussion starts to hit too close to home, just remind yourself – we’re talking about zebras.

So – Dave the zebra and his buddies are out enjoying some pasture. Suddenly, Dave spots that lion hiding behind the big rock.
Dave’s amygdala goes into survival mode. His adrenal glands kick in, so he feels an adrenalin rush. His breathing gets faster and his heart rate speeds up. His large muscle groups tense up: the idea here is to get as much muscle strength as possible, to give Dave the best chances of survival.
When blood flow is focused on feeding your big muscle groups so you can run or fight, your extremities are not a priority. That’s why your hands and feet might get cold and clammy: they’re not getting a lot of blood flow.
You sweat because sweating is the body’s way of cooling off. Survival reflex expects you to have to run or fight, which heats the body up. So, reflex thinks that breaking out in a cold sweat is a nice, thoughtful way of helping out.
Since the survival reflex directs all available energy towards survival, it shuts down functions that are not essential to dealing with the immediate threat. So, your survival reflex will suppress your digestive system and your immune system, because these seem like a waste of energy when your survival is being threatened.
That, in a nutshell, are the main physical symptoms of the survival reflex. Next up – the emotional impact of the fight/flight/freeze response.

I’d love to have you share your thoughts, comments, and questions – but before you post, can you take a quick peek at the guidelines? Thanks…
Fine print: Reading this blog is a good start, but if you’re having a hard time, it’s no substitute for getting actual help (like, therapy). It takes a different kind of courage to admit to yourself that you’re struggling, and to seek help. PTSD is not a sign of failure – it’s a sign that you’ve been through a lot, and have tried to stay strong for too long. If you need help – you’re in some pretty great company. Reach out, and give yourself a chance to feel better.
