WHAT IS STRESS?HTTPS://WWW.YOUTUBE.COM/WATCH?V=S93YWQFA6CM
Stress is the effect of physical and psychological demands on a person.Almost everyone feels the effects of stress (argument with a friend, a lower than expected grade, a minor auto accident)
Positive events can also cause stress (receiving an award, moving from JV to Varsity)
TYPES OF STRESSChronic Stress
Chronic Stress- unrelieved stress that continues to tax a person’s resources to the point of exhaustionThe heart and blood vessels suffer the most damage from stress.
Energy gives way to exhaustion = sickness
Acute Stress
Acute Stress (Short-term stress)- a temporary bout of stress that causes alertness or alarm, which prompts a person to deal with a specific event Can bring new energy (studying for a test or completing a project)
If this stress continues over a period of time, it becomes chronic stress
Many people wait to long to deal with their stress-take action as soon as you notice signs
STRESSORS
Stressor - A physical or psychological demand that requires a person to adapt to a situation.Physical Stressors- air temperatures, intensity of lighting, injury or radiation

PERCEPTION OF A STRESSOR
An event may be more or less stressful depending on how YOU perceive that event!
Your life experiences shapes your perceptions.
To produce stress, an event must be perceived as threatening.
Example: Thunderstorms, Snakes
SECTION 2STRESS AND YOUR BODY
All of the body’s systems are affected by stress, but 3 systems in particular are affected:The Nervous systemThe Hormonal systemThe Immune system
THE NERVOUS SYSTEM Manages the body’s activities by sending and receiving messages between the brain, spinal cord, and nerves.Whatever the stressor, the nervous system always produces a set of reactions to restore normal condition inside the body (Example: cold weather) In cold weather, your nerves in your skin act as a thermometer, sending “cold” messages to the spinal cord and brain Goosebumps Shiver – to produce heat
THE HORMONAL SYSTEM
A system of glands that control body functions in cooperation with the nervous system.
Both systems complement each other in helping the body adapt to changes in the environment.Hormone - chemical that serves as a messenger.Each hormone is released by a gland
Gland- an organ that secretes one or more hormones in response to information about changing body conditionsRelease hormones into the bloodstream to control conditions
THE HORMONAL SYSTEM CONT’D
Stress hormones-control body’s responses to stress.
These 2 stress hormones regulate the body’s activities during emergencies or stress.Epinephrine- adrenalineNorepinephrine- noradrenaline
THE IMMUNE SYSTEM
The cells, tissues, and organs that protect the body from disease.
Activity of the immune system is lower than normal during stress
Between periods of stress, immune sys. recovers quickly
Short periods of stress followed by periods of relief from stress can strengthen the immune sys.
Long period of unrelieved stress can reduce # of WBC
Includes white blood cells, bone marrow, thymus gland, & spleen
White blood cells are the body’s main cells of immunity (made in bone marrow) WBC make antibodies, body’s main ammo against infections
SECTION 3THE STRESS RESPONSE
A little stress can be beneficial, but too much stress, unrelieved, can be exhausting and harmful.
Stages of The Stress Response: Alarm- 1st phase in which you recognize you are facing a change or challenge (body releases stress
hormones)
Resistance-2nd phase in which the body mobilizes its resources to withstand the effects of stress (These include your attention, your strength, and fuels). You can use your resources until they run out or wear out. Then you need to replace or repair them.
Recovery or Exhaustion- 3rd phase is one of two opposite states. Recovery-occurs when the body returns to normal-you deal with the stress or it goes away Exhaustion-harmful 3rd stage of the stress response. Stress exceeds the body’s ability to recover.
Recovery is delayed or becomes impossible. If stress continues and your body becomes exhausted, you can become sick.
PHYSICAL REACTIONS TO STRESS RESPONSE
Each stage of the stress response involved physical reactions:
Alarm Stage- heart rate speeds up, pupils widen, muscles tense, fuels (fat is released from storage to be used by muscles), blood flow to skin and digestive organs is reduced.
Resistance Stage-puts your body in an unbalanced state. Muscles flex while body functions shut down. This state helps your body deal with an emergency. Body functions become balanced again when the danger has passed (Recovery Stage)
Prolonged stress can make diseases of the heart and arteries likely During stress, fat is released into the bloodstream. Fat fuels muscles, but it may not be used up
if no physical action occurs. When fat remains in the bloodstream, it collects along artery walls , damaging them.
In this way, Psychological stress=development of heart disease
SECTION 4MANAGING STRESS
Strategies for managing stress include:
1. Be physically active (keeps body strong, strengthens immune sys)
2. Relaxing (progressive muscle relaxation, reading a book, taking a walk, music)
3. Managing your time (plan ahead, make a time budget)
4. Using coping devices (safe, short term methods of managing stress)
A. Displacement- transferring the energy of suffering into something else
B. Venting- verbally expressing one’s feelings-”letting off steam”
COPING DEVICES CONT’D
C. Defense Mechanisms- automatic, subconscious reactions to emotional injury- used in cases of serious stressD. Denial- refusal to admit something is unpleasant or painful has occurred
“No, I don’t believe it.”E. Fantasy- involves imagining, in the face of a painful or unpleasant situation, that something positive has happened instead.
“She didn’t really die, she just went on vacation”
DEFENSE MECHANISMS CONT’D
F. Projection - the belief, in the face of an unpleasant or painful situation you have caused, that it is another person’s fault.
“The teacher asked the wrong questions on the exam.”
G. Idealization - idolizing
“ I would love to be Molly, she has everything and does everything so well.”
H. Regression - using inappropriate , childish ways of dealing with painful realities
“ I’m not going to do it!!! ( While stomping feet like a child)
DEFENSE MECHANISMS CONT’D
I. Repression - keeping disturbing or threatening thoughts from becoming conscious
Memories of abuse as a young child make it difficult to form relationships now
J. Compensation - people overachieve in one area to compensate for failures in another
Student who has a poor home life directs his energy to excelling above and beyond in school
K. Rationalization -justification of an unreasonable action or attitude by manufacturing reasons for it.
“ I couldn’t prevent the accident because I had to pay attention to something else.”
