3. What is stress?
Stress is the way that you react physically,
mentally and emotionally to various conditions,
changes and demands in your life.
Many students experience varying levels of stress
each semester.
High levels of stress can affect your physical and
mental well-being and academic performance.
5. What causes stress?
Anxiety: uneasiness and distress about future
uncertainties
Changes in life’s expectations or demands
Ex. Marriage, divorce, pregnancy, illness, bills,
increasing demands of a university course load
Disorganization: feeling unprepared and
powerless
6. What causes stress?
Physical Constraints
Ex. Physical exhaustion, lack of good exercise and diet
strategies
Time constraints: multiple projects and deadlines
7. Exercise: Self-assessment
Take the anxiety/stress assessment
Use the results of this assessment to pinpoint specific
causes of stress in your life. What (if any) control do
you have over these areas of your life?
Make a list of things that you can do to lessen your
stress.
8. Strategies to reduce stress
Take control. Manage your time instead of
letting it manage you. Use a to-do list, follow a
written plan, set goals and follow through.
Avoid procrastination, a major cause of stress.
Make a realistic list of things you need to do each
day. Do the most important things first. That
way, even if you don’t finish the list, you get the
most important things done.
9. Strategies to reduce stress
Take a break
Sometimes it is better to get away from the situation
for a short time. Take a brisk walk, focus on pleasant
thoughts. Then, go back to the task feeling refreshed
and ready to tackle whatever it is you have to do.
10. Strategies to reduce stress
Work on your attitude
Put things into perspective. Do not to take
yourself too seriously.
Think positive. “If you think you will fail, or
think you will succeed, you are probably right.”
--Henry Ford
11. Strategies to reduce stress
Get help
See your instructor, go to tutoring, and participate in
study groups. See how to form a study group.
Keep in touch with friends and family, and
develop a support group.
12. Strategies to reduce stress
Physical stress busters
Eat right, exercise regularly and get plenty of rest
Practice, practice, practice
Build your confidence: do extra math problems,
practice test-taking at home, rehearse your speech a
couple of times before the presentation
13. Self-reflection
Go back to the stressful incident that you
described in the first part of the workshop.
List some strategies for dealing with the situation,
List some things you could have done to prevent it
from being stressful.
List some ways you can avoid a reoccurrence of such a
situation in the future.
14. Strategies for dealing with stress
No one can avoid stress all the time. In a stressful
situation, try these tips to help you overcome the
effects of stress.
Join the crowd
Even though you may think you are the only person in
the world who is experiencing stress, the fact is that
everyone experiences it sometime.
15. Strategies for dealing with stress
Talk to someone
Find someone you trust, discuss the problems and look
for solutions
Put it in perspective
Chances are, this is only one small part of the rest of
your life
Visualize
Sit comfortably and think of a favorite place. Imagine
yourself in a successful situation.
16. Strategies for dealing with stress
Visualize
Sit comfortably and think of a favorite place. Imagine
yourself in a successful situation.
Breathe
Sit quietly, and breathe deeply and slowly. Continue
for five or six breaths. It is calming and the extra dose
of oxygen increases the brain’s thinking ability.
17. Strategies for dealing with stress
It’s all in your head... and shoulders
Roll your head loosely in a wide circle. Repeat five
times. Tighten right shoulder and raise it as far up as
possible and hold, then relax slowly. Repeat with left
shoulder. Repeat with both shoulders.
18. Strategies for dealing with stress
Go on a diet
Eating light and avoiding sugars can help with
performance and lessen stress. In a stressful situation
like an exam, have a light meal of mostly protein.
Remember, a heavy high carbohydrate meal can put
you to sleep.
19. Strategies for dealing with stress
Lighten up
Take responsibility for your feelings. When you get
angry, take a break and cool down before you act.
20. Strategies for dealing with stress
Use it
A little stress is a good thing. Athletes use it to
increase performance. If you are experiencing a small
amount of anxiety, it can help to keep you active and
alert. Use it to increase your performance.
21. Summary
Stress is mental, emotional and physical tension,
strain, and/or distress
The signs of stress are classic. You may get a
headache, stiff neck, backache, become irritable,
lose your temper, and you may feel exhausted and
find it hard to concentrate.
When these symptoms appear, recognize them as
signs of stress and find a way to deal with them.
Just knowing why you’re feeling the way that you
are may be the first step in coping with the
problem.
22. Fatigue, Decision Making,
and the Fire Line
The ability to make decisions is
critical when fighting wildland fires.
Some level of stress and perhaps
fatigue can bring about clarity and
concentration. Too much fatigue
and stress however – will disrupt
decision making capabilities.
People perceive and process
information differently. How does
fatigue influence how we interpret
and process information?
23. Key Terms
Arousal: level of physiological
and psychological activity at any
given moment; occurs on a
continuum
Stress: physiological and
psychological response to a
challenge that requires some
form of adjustment
Anxiety: negative end of
arousal; characterized by worry,
nervousness, and apprehension
24. Key Terms
State Anxiety:
describes the level of
anxiety at any given
moment; moment-to-
moment anxiety; ever-
changing mood
Cognitive State
Anxiety: the negative
thoughts and worries one
has in an anxious moment
Somatic State Anxiety:
how the physiology
responds in anxious
moments – real or
perceived
Trait Anxiety: one’s
predisposition to
perceive challenges;
acquired behavioral
tendency
Decision Making: the
process of considering
and selecting
alternatives
Fatigue: decreased
capacity to complete
work; physical or mental
weariness
25. Understanding Stress
Lazarus’s Cognitive
Theory of Stress
Suggests that it is one’s
perception of a stressor that
causes stress – not the
stressor itself
What Causes
Negative Stress?
A perceived imbalance
between the challenge
(physical or psychological)
placed on an individual and
their ability to overcome the
challenge.
26. Lazarus’s Cognitive
Theory of Stress
Primary Appraisal
Person determines if event
or stimulus is negative,
positive, or neutral.
Secondary Appraisal
Person evaluates their level
of control, coping resources
available, and considers
options.
Stress Response
How the person reacts
physiologically, emotionally,
and behaviorally.
27. How People Will React
Is Not A Given
“Men are
disturbed not by
things but by the
views which
they take of
them”
Epictetus
55-135 A.D.
It is not cut & dry how people
will respond in the fire
setting. Experience will
impact appraisal – but how?
How people will respond is
difficult to understand.
Emergency workers often do
not want to participate in
research.
Fear is not always reliable –
we never really know where
“the edge” is.
28. Positive Appraisals Even In
Extreme Circumstances???
A new sense of meaning or
feeling good about one’s
contribution in a disaster
response (Anderson, et al.,
1991).
Exhilaration, sense of
occupational achievement,
enhanced appreciation of
life, and a sense of control
(Moran and Colless, 1995).
29. Arousal, Anxiety, and
Performance
How does arousal
(physically or psychologically)
and anxiety affect
performance (positively
or negatively)?
A number of theories
have been developed
to help explain the
connection.
Drive Theory
Linear relationship between
arousal and performance
Inverted-U Hypothesis
Maximum performance is at a
midpoint of arousal
Catastrophe Model
There is a threshold between
anxiety and performance
Reversal Theory
Depends on a person’s
interpretation of their arousal.
30. Achieving a Balance
Between Demand and
Abilities
Perhaps the
best model to
strive for is the
Flow Model.
Achieving “flow”
has to do with
one’s level of
preparedness.
31. Causes of Fatigue
Energy System
Depletion
Phosphocreatine
Glycogen
Blood Glucose
Accumulation of
Metabolic By-Products
The role of lactic acid
Failure of contractile
fiber recruitment
Central Nervous System
Involvement
Neuromuscular Fatigue
Fatigue of the CNS
(“central fatigue”)
Environmental Temperature
Increased energy demands
Nutritional Influence
Type of calorie
Timing of intake
32. Effects of
Progressive Dehydration
1% body weight loss = thirst
2% body weight loss =
increased thirst, loss of appetite,
discomfort
3% body weight loss =
impatience, decreased blood
volume
4% body weight loss = nausea,
slowing of physical work
5% body weight loss = difficulty
concentrating, apathy, tingling
6% increased body temp, pulse,
and respiration rate
7% body weight loss =
stumbling headache
8% body weight loss =
dizziness, labored breathing
9% body weight loss =
weakness, mental confusion
10% body weight loss =
muscle spasms, indistinct
speech
11% body weight loss = kidney
failure, poor circulation due to
decreased blood volume
33. Fatigue and the
Willingness to Take Risks
There is some evidence (anecdotal and
risk analysis) suggesting that fatigue
and other negative emotions have an
impact on decision making and risk
taking. Example: When do most
industrial accidents occur?
Analytic processing can be reduced,
information may not be processed
completely, and this can increase the
chance of risk choices being made.
Ultimately, who is taking the risk?
34. Characteristics
That Affect Risk Taking
People may be at risk because
of too much experience or too
little experience.
Risk Taking Characteristics:
State Fatigue
State Anxiety
Familiarity
Importance
Changes in fatigue show the
greatest affect on risk behavior.
36. Are You Prepared
to Make Good Decisions?
Years of Experience
Sensitizing or Desensitizing Effect
Critical Incident Involvement
What is being passed on?
Who are you modeling?
“We’ve survived so it must work.”
How close to the edge are you?
Training
Adequate or Inadequate
Skill Acquisition
What more could we do?
37. Skill Determination
and Acquisition
The first step toward
becoming a good
decision maker on the
fire line is to recognize
that fatigue hampers
your ability to make
appropriate decisions –
fatigue affects everyone.
Training should include
simulation to help people
anticipate events and
predict how they will
react.
Emergency workers tend to
be optimistic which may
make them more vulnerable
(Taylor, 1989).
Take the necessary steps to
prevent and minimize
fatigue.
Determine your skill
strengths and identify skill
weaknesses. Actively work
on improving your skill
base.
38. Fatigue Prevention

45. Striking a Balance Between
Skill and the Challenge
Mental and physical performance
is always better when we are in
our comfort zone. To get into that
comfort zone, there needs to be a
balance between our skill – real
and perceived – and the
challenge or demand.
Making good decisions on the fire
line are more likely if one strives
to stay in their zone.
46. Balance and Your
Level of Preparedness
Are you prepared to meet the
challenge? What is your
Level of Preparedness?
Do you have the proper
motivation to perform well?
What are your primary goals?
Optimal performance
generally stems from a well
designed plan. What is the
plan? And are you confident
in that plan?
47. Other Skills That Influence

52. Other Helpful tips
Changing perceptions and expectations
Break jobs/tasks into manageable parts
Set reasonable/realistic goals
Avoid procrastination
Set boundaries
Don’t compromise your values/beliefs
Schedule “me” time
53. Benefits of Stress
Management
Physical health gets better
-more energy and stamina
Emotions stabilized
-positive attitude
-hopeful/happier
Ability to focus improved
-able to learn and achieve
54. Relax
Our brain fires electrical waves at 14 or more
cycles a second.
These are beta waves and are great for getting
tasks done, but not for learning new things.
Taking a few minutes to relax deeply slows your
brain waves down.
These slower waves are alpha waves.
They occur at between 7 and 14 cycles a second
Studies show alpha waves improve learning.
----”OnCourse” by Skip Downing
Fatigue has been identified as a contributing factor in a number of fires that resulted in deaths (e.g Storm King and 30 Mile). People seem to understand that stress and fatigue have an impact on our ability to perform physically and mentally – but they are not sure what to do about it.
I was asked to come in and try to make some sense with it and suggest possible solutions. There isn’t much research out there specifically-related to firefighters – but there is some research in other stressful professions (med school students, air traffic controllers). An interesting connection with sport however. The ability to physically perform well even though you are in a mentally challenging situation.
Explain my background with wild land fire training, sports psychology, and exercise science – including training theory & application, and functional anatomy.
Ask group how they got to their current positions. What kind of experience and experiences did they have to have? What level of training did they receive? Have they had any training on decision making and decision making and fatigue? Write it up on a board for later and compare to the “preparedness pyramid.”
Have group define arousal, stress, and anxiety.
Many things go into decision making (info gathering, reasoning, concentration, field of focus, past experiences). Fatigue interferes with the normal decision making process.
There are many models used to explain how stress (mental and physical) can impact physical performance and behavior. We will talk about a couple of them.
It is important to:
First) understand the connection between the mind and body; know what drives what
Second) make attempts to prepare yourself mentally for the challenges of your job. Preparation can and should take many forms (e.g. experience, training –including simulation, mental focus and concentration techniques, fitness, nutritional strategies).
Remember:
Behavior is the physical bridge between
inner experience and the outer world.
Go over 3 phases of this theory.
In Stress Response phase – talk about General Adaptation Syndrome. Use overheads if class does not know much about this theory.
Using graphics from above – explain the MIND CONTROLS THE BODY idea , the power of the mind, “you are what you think about”, etc.
Some of our interpretations are habitual.
Use the Self Esteem Failure and Success Cycle over head. Do the “test anxiety”example.
Have the class walk through another example with their table.
It is very difficult – perhaps impossible - to determine how a person is going to reaction in critical times. Our experiences are different, our processing abilities are different, our views/mindsets are different, and maybe even our goals are different.
It is also hard to study – and thus understand – how people will react in emergency settings and how things like experience actually affect. Reasons for this are:
1) there maybe a stereotype person who becomes a firefighter and thus the recruiting attempts and hiring practices are looking for this type of person. Perhaps more vulnerable. So how does this group compare to the general population?
2) emergency workers appear to be unaffected by traumatic experiences. Maybe, maybe not. Personal preservation? Experience? Perhaps more vulnerable.
3) Following traumatic experiences, many emergency workers do not want to participate in research – so how can we learn from their experience?
Fear IS NOT ALWAYS reliable – Jon Turk. There are times when you are scared/nervous with good reason, other times you are scared but shouldn’t be, and times when you aren’t scared but you should be. Why is this? Because it is difficult to determine exactly where “the edge”is. You are blind to where the edge is – once you are over the edge – you could be dead…and then it is too late.
Preparation is very important – planning to determine how much “bad luck”you can withstand.
In wild land fire, people are sometimes relying on others to tell them how close they are to the edge. Inexperienced, undertrained personnel may not even realize how close to the edge they are – and thus they are at great risk. But experienced people can be close to the edge and not know it.
Drive Theory: (Spence 1966) saw a direct and linear relationship between arousal and performance. As arousal (state anxiety) rose so did performance. But it doesn’t identify a cap and it does not explain why elite people choke.
Inverted- U Hypothesis: low arousal levels bring about sub par performance. As arousal rises, so does performance to an optimal point. Then as arousal goes higher – performance drops. So a person can be under or over aroused. Problem is, optimal performance does not always occur at the midpoint.
Catastrophe Model: explains a relationship between arousal and cognitive anxiety. As physiological arousal increases – so does performance (like the Inverted-U) as long as person is not worried (cognitive anxiety). If cognitive anxiety increases – at some point it reaches a threshold and then you crash. So it is possible for a person to have a great deal of physiological arousal (somatic anxiety) – but as long as they main their worry level – performance will improve.
Reversal Theory: how arousal affects someone depends on how the person’s interpretation of their arousal. They must interpret the arousal as a positive thing, a pleasant or exciting situation. But interpretations can change moment by moment.
These theories (or parts of the theories) help us understand how stimulus and arousal affect our performance (physical and mental) and our concentration level.
Do the Flash Card activity.
The key to effective performance (including our ability to make good decisions) is to find a balance between the challenge or demand(s) and our level of preparedness (the various skills necessary to overcome the demand).
Flow is a model used to describe optimal performances. Athletes often call it the Zone, they were hot, in the groove, etc.
If the challenge is too high for the given skill level = anxiety results = bad decisions are more likely.
Skill level too high for the challenge = boredom and apathy can result = leading to bad decisions.
It is important for you to understand these causes for your sake – not to also understand what is going on with your crews.
Excessive activity and long shifts can bring about fatigue. Talk about the 3 energy systems (ATP-PC, glycolysis, and oxidative) Rate of fatigue and uses.
View ALL this info in relation to your job – and others on the fire line.
Accumulation of Metabolic By-Products: lactic acid is a by-product of muscular activity – brief, intense activity, not slow sustained efforts. It changes the acidity level of the muscle. Lactic acid is converted to lactate which causes the accumulation of hydrogen ions. Hydrogen displaces calcium which interferes with the cross bridge cycle. This decreases the production of energy (ATP cannot be split) and reduces muscle fiber (motor unit) recruitment.
Use Sliding Filament overhead and diagram a motor unit.
CNS fatigue: the precise mechanisms of CNS fatigue is not completely understood. But there is some involvement which is exampled by situations where someone appears to be at complete fatigue and then someone yells at them or words of encouragement and they find more energy.
Serotonin (neurotransmitter – has been used to treat insomnia) and tryptophan (amino acid, precursor to Serotonin) appear to play a role in central fatigue. Levels of both are higher at states of fatigue or after prolonged activity.
Environmental Temperature: increased body temp – increases heart rate – which increase oxygen uptake – this increased respiration demands more energy – which requires the muscles to use more glycogen.
Nutritional Influence: the type of calories one eats influences the rate of fatigue. USE TWO CHO Diet OVERHEADS. (On overhead, Low CHO Diet means 40% - high means (70%).
We will look at this more when we get to the prevention of fatigue.
1% dehydration (body weight loss) = 1.7 pounds of fluid for a person who weighs 170 pounds.
How much weight do you lose during a day on the fire line? Where does that put you on this chart of the effects of dehydration?
You are probably aware that as one fatigues – there is often a reduced level of mental effort. People start to take shortcuts instead of working systematically through all the options. The studies are a bit sparse in this area – but there is some evidence that fatigue and some negative emotions might alter our ability to make decisions – often making decisions without using all of the available information.
The experience question has to do with familiarity and perhaps our view of the importance of the event. We tend to believe that with experience we become more sensitized to situations. There is some evidence however – that some people become desensitized as a result of experience.
No one is saying that experience isn’t a good thing – but it is possible that for some people, their ability to judge threat maybe impaired because they have been in this situation many times in the past “Been there – done that.”
Other things will also affect your willingness to take risks – such as our state anxiety, importance of the event, and how familiar we are with a situation. Use Willingness to Take Risks overheads.
Go over first level of pyramid on this slide. Then go to next slide.
Years of Experience: when past experience with stressors appears to enhance our coping – it is called “stress inoculation.” Repeated exposure – they treat phobias this way. Is experience always good? How are you modeling? What is being passed on?
Training: Go back to the list class created at the beginning of the class regarding how they got to their current positions. Has the training been adequate, up-to-date, and given in a timely fashion?
Water Intake Recommendations: For the typical person – has to do with calorie expenditure. Adult: 1.0 to 1.5 milliliters per calorie expended. So if a person burns off 2,400 calories in a day – they need to be replacing about 2.4 liters of water – for optimal performance.
29.57 ml = 1 ounce = 2 Tablespoons = 6 teaspoons
1 cup = 236.6 ml
1 pint = 16 oz = 473.1 ml
1 liter = 1.057 quarts
Key point to remember: the more active you are – the more difficult it is to keep up with the fluid battle or glucose battle.
Active people need even more – with endurance athletes needing the most. So where do firefighters fall on this continuum? What about Division Supervisors?
Chilled and Flavored promote greater consummation. Space out the drinking if you get stomach upset from drinking too much at one time. Set your watch as a reminder.
Glucose Recommendation: ( 1 gram per minute is the high end recommendation for athletes/ 45 to 60 grams per hr)
4 to 8 grams of glucose per 100 ml of water should not interfere with gastric emptying. Need to consume 100 to 150 ml every 10 to 15 minutes to prevent dehydration and maintain energy (including clear thinking). Most Sports Drinks contain about 6 to 8 grams of sugar per 100 ml.
Sodium Recommendations: Eat! Sport Drinks have sodium also. If necessary – because of cramping – add a bit more salt to food. The problem with salt tablets is that people do not consume enough water with them. This can lead to dehydration, stomach cramping, GI upset, and elevated BP. For the most part, get your sodium from your foods.
16 oz before: Takes 60 to 90 minutes for water to clear
Don’t wait for thirst – thirst is a delayed response to your need for water.
Your need will be different than the needs of endurance athletes – different than your crews (hotshots, jumpers, etc.)
Practical advice: drink!
Drink 2 cups before you come on
Drink as much as possible at lunch and dinner
Take breaks during the day to drink
Replace Fluids at night
Avoid caffeine since it causes increased urine output
Avoid alcohol because it leads to dehydration
For every pound lost in body weight = drink 2 cups of water
One thing to talk about is the attempt to maintain blood sugar levels throughout the day by frequent eating. Avoid the low points when mood, concentration are affected. Example: common recommendation when shopping is never shop on an empty stomach. We make, justify, and rationalize bad decisions.
Ultimately, your goal is to do the things necessary to create a balance between the demands placed on you and your ability to manage those demands.
Concentration: internal distracters and external distracters.
