Stress begins with something called the hypothalamus pituitary adrenal axis, a series of interactions between endocrine glands in the brain and on the kidney, which controls your body's reaction to stress.

压力开始于一种叫做下丘脑垂体肾上腺轴的东西，一连串的相互作用，在大脑的内分泌腺和肾脏之间，它会控制身体对压力的反应。

It's also thought that the brain's Hypothalamic-Pituitary-Adrenal axis can't regulate stress hormones properly, contributing to PTSD symptoms and causing intense waves of stress, fear, and depression.

人们还认为， 大脑的下丘脑-垂体-肾上腺轴无法适当调节压力荷尔蒙，从而导致 PTSD 症状并引起强烈的压力、恐惧和抑郁。
