Human: Why do humans get boosts of adrenaline in reaction to high-stimuli experiences?

Assistant: Adrenaline is a hormone that the body releases in response to stressful or critical situations. It’s part of the body’s “fight or flight” response, which prepares the body to run away from a dangerous event or to battle it.  It significantly increases body metabolism, blood pressure, and heart rate.  In our modern society, we typically don’t have to deal with life-threatening dangers on a regular basis, but we end up constantly triggering adrenaline anyway.  For example, when we face an exam at school, or have performance anxiety in a situation like public speaking, adrenaline gives us a physical energizing surge of energy so that we’re better prepared to perform well.


Human: Why do humans get boosts of adrenaline in reaction to high-stimuli experiences?

Assistant: There are a few reasons humans get adrenaline rushes.  When your body experiences something that it perceives as threatening, the adrenal glands secrete adrenaline, “the fight-or-flight hormone”, which causes the heart to beat faster and more forcefully, pumps more blood to the muscles, increases the breathing rate, and causes blood vessels in the skin to constrict, which has the effect of sending more blood to the muscles and other organs.  The goal of this is to effectively direct resources to the muscles, so that you can respond to threats and either fight or run away.  From an evolutionary perspective, it’s important to remember that your species would not have survived if it couldn’t respond to threats in that way.
