AP PSYCHOLOGY

Detailed explanation-1: -A stressful situation, whether environmental or psychological, can activate a cascade of stress hormones that produce physiological changes. Activation of the sympathetic nervous system in this manner triggers an acute stress response called the “fight or flight” response.

Detailed explanation-2: -Adrenaline increases your heart rate, elevates your blood pressure and boosts energy supplies. Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues.

Detailed explanation-3: -There are three stages to stress: the alarm stage, the resistance stage and the exhaustion stage. The alarm stage is when the central nervous system is awakened, causing your body’s defenses to assemble. This SOS stage results in a fight-or-flight response.
