Detailed explanation-1: -Adrenaline causes many immediate changes in your body, as a shown in Figure 4. Your heart beats faster, your breathing speeds up, and your muscles tense. Your attention narrows as you focus on the stressors.

Detailed explanation-2: -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. The resistance stage is when your body begins to repair itself and normalize heart rate, blood pressure, etc.

Detailed explanation-3: -Stimulation by the sympathetic system nerves results in an increase of heart rate, as occurs during the “fight-or-flight” response.

Detailed explanation-4: -The term ‘fight-or-flight’ represents the choices that our ancient ancestors had when faced with danger in their environment. They could either fight or flee. In either case, the physiological and psychological response to stress prepares the body to react to the danger.

Detailed explanation-5: -Your sympathetic nervous system is a network of nerves that helps your body activate its “fight-or-flight” response. This system’s activity increases when you’re stressed, in danger or physically active.
