Explanation:
Detailed explanation-1: -During the classic “fight-or-flight” stress response, sympathetic nervous system activation leads to catecholamine release, which increases heart rate and contractility, resulting in enhanced cardiac output.
Detailed explanation-2: -These hormones cause the sympathetic nervous system to stimulate the pituitary gland and adrenal glands. This triggers the release of catecholamines, including adrenaline, noradrenaline, and cortisol. This chain of reactions results in an increased heart rate, blood pressure, and breathing rate.
Detailed explanation-3: -Deep breathing, relaxation strategies, physical activity, and social support can all help if you are feeling the effects of a fight-or-flight response.
