Challenging the Neurobiology of Stress Response Do you remember when you were a kid in school and you heard the teacher unexpectedly say the words pop quiz? Do you remember your heart starting to race and your palms getting sweaty as you waited for that dreaded sheet of paper to be passed down the row? That was your stress system at work. It turns out that little jolt of adrenaline you felt helped you remember all those state capitals better than if you hadn’t gotten it. These brief bursts of stress are your body’s nervous system becoming aroused. Stress, in other words, is not all bad. Research has shown that moderate amounts of stress can be beneficial for our health, strengthening our immune system and cardiovascular system and speeding recovery from injury. Our stress systems also work as a vital warning system to help us get out of danger when we need to flee from a burning building or jump out of the way of a speeding car. On the other hand too much stress, especially when it lasts for a long time with no end in sight, can be dangerous for our health.
