When the fight or flight mechanism gets activated what is released into your blood stream?

When the fight or flight mechanism is activated, the body releases stress hormones, primarily adrenaline (epinephrine) and cortisol, into the bloodstream. These hormones prepare the body for rapid action by increasing heart rate, boosting energy levels, and redirecting blood flow to essential muscles. This physiological response enhances alertness and prepares the individual to either confront or flee from perceived threats.
