Watch this amazing TED about trauma…here’s a taster of what Nadine Burke Harris will share with you in her presentation, which explores the underlying neuroscience.

Well, imagine you’re walking in the forest and you see a bear. Immediately, your hypothalamus sends a signal to your pituitary, which sends a signal to your adrenal gland that says, “Release stress hormones! Adrenaline! Cortisol!”

And so your heart starts to pound, Your pupils dilate, your airways open up, and you are ready to either fight that bear or run from the bear. And that is wonderful if you’re in a forest and there’s a bear. (Laughter) But the problem is what happens when the bear comes home every night,and this system is activated over and over and over again, and it goes from being adaptive, or life-saving, to maladaptive, or health-damaging.

Children are especially sensitive to this repeated stress activation, because their brains and bodies are just developing. High doses of adversity not only affect brain structure and function, they affect the developing immune system, developing hormonal systems, and even the way our DNA is read and transcribed.”
