Document Summary

Physical reaction that is accompanied by emotional reaction, which dictates how people cope. Stress refers to: situations that trigger physical and emotional reactions = stressor, the reactions themselves = stress response. Stress: the general physical and emotional state that accompanies the stress response. The primary determinant of the health consequences of stress is how the individual responds to the stress. Responses to stressors include: physical changes, emotional and behavioural responses. Two control systems are responsible for the physical response to stressors: nervous system. Part of the nervous system that is not under conscious supervision. Aids in digestion, storing energy, growth promotion. Activated during arousal and emergency situations (pain, anger, fear) Releases norepinephrine which commands body to mobilize energy resources to respond to crisis and causes arousal (increase attention and alertness) when released in the brain: endocrine system. The system of glands, tissues, and cells that help control body functions by releasing hormones and other chemical messengers into the bloodstream.
