UNIT 2: Stress Management Flashcards
What is Stress?
The collective physiological and emotional responses to any stimulus that disturbs an individual’s homeostasis
Stress is determined by the balance between perceived demands of the environment and the individual’s resources to meet those demands
What is known as the “Unstressed” State?
homeostasis = a balanced and stable environment
What is a Stressor?
any physical or psychological event/condition that produces stress
Moves away from homeostasis
What is a Stress response?
the physiological changes associated with stress
What makes things stressful?
4
- Novelty
- Unpredictability
- Threat to ego
- Sense of loss of control
What are Top Stressors in the lives of College Students?
- The Future: job after school
- Money/finances (cost of education/loans)
- Academia (grades)
- Too many things to do
- Lack of time for tasks
What are Environmental Stressors?
– Climate, noise, pollution, crowding, time of day
What are Physiological Stressors?
external or internal stimuli that disrupt the body’s homeostasis, triggering a physiological response aimed at restoring balance and adaptation to the stressor
Training, medications, caffeine, injuries, disease, nutritional status
What are Emotional stressors?
2
Major stressors: those that create major turmoil and usually require major adjustment and time implement the changes
Minor stressors: those that are short term and/or less severe
What is Acute Stress?
short-term, single event
flight or flight response
What is Episodic Stress?
series of events (transient)
What is Chronic Stress?
long-term, always present
What are terms for positive and negative stress?
Eustress = stress triggered by a pleasant stressor
Distress = stress triggered by an unpleasant stressor
What are characteristics of Hans Selye’s General Adaptation Syndrome? (1936)
Proposed 3 phase to chronic stress:
– Alarm -> prepare for ‘flight / fright’ - Release Hormones
– Resistance -> resistance to stress, improved coping
– Exhaustion -> inability to cope, life-threatning physiological exhaustion

Hoe does Stress/Emotional Arousal affect performance?
Symptoms of Excess Stress
What Two systems are responsible for physical response to stressors?
the Nervous System and the
Endocrine System
What is the Autonomic nervous system?
What are its two divisons?
- Not under conscious supervision
- Controls heart rate, breathing, blood pressure, digestion, and hundreds of other involuntary function
- Consists of a Sympathetic and Non-Sympathetic Divison
What is the Sympathetic Divison of the Autonomous Nervous System?
Sympathetic division = is activated during times of arousal, including exercise, and when you face an emergency, or experience severe pain, anger, or fear. Sympathetic nerves use the neurotransmitter norepinephrine
What is the Parasympathetic Divison of the Autonomous Nervous System?
Parasympathetic division = moderates the excitatory effect of the sympathetic division. In control when you are relaxed; it aids in digesting food, storing energy, and promoting growth
How are different body parts affected by the activations of either the sympathetic or parasympathetic division?

What is Adrenaline?
Origin, Target, Function
(aka epinephrine)
(four)
Hormone + Neurotransmitter
Origin:
Medulla of Adrenal Glands
Function:
- Increase HR
- Increase BP
- Increase Blood Sugar
- Dilates Airways
Target:
heart, blood vessels, airways, and liver
What is Noradrenaline?
Origin, Target, Function
(aka Noraepinephrine)
Hormone + Neurotransmitter
Origin:
Medulla of Adrenal Gland
Function:
Mainly Increase BP by Vasoconstriction
same as adrenaline
Target:
heart, blood vessels, liver, lungs
