Transcript of Stress
From Sniffles to Forgetfulness
Acute stress boosts cardiovascular performance
w/too much adrenaline, it stops regulating surges your blood pressure
When stress affects our immune system:
responds better to flu shots
coax the immune system to fire even to targets that aren't shooting
**stress can harm learning when too severe BUT if stress isn't
severe, the brain performs better**
The Hero...The Villain
The Villain: Cortisol/Glucocorticoids
- secreted by adrenal glands
- if given free access to the brain, can do major damage
- can disconnect neural networks of brain cells
The Hero: Brain Derived
Neurotrophic Factor (BDNF)
- powerful group of proteins, neurotrophins
- keeps neurons alive and growing
What do they do?
They drop both the frequency and severity of hostile interactions between husband and wife.
famous marraige researcher
can predict future of relationship within 3 mins of interacting
90% success rate for his predictions
How is he so successful?
After many years of practice, he isolated specific marital behaviors, both +/- that held most of the predictive power.
Gottman stated that by testing the urine sample of the parents' child(ren) he can also predict the quality of their relationship.
Many causes of stress from children
Gottman and Alyson Shapiro's Idea:
Before the depression can reach the mother:
"bringing baby home": exposing their marriages to the interventions whether needed or not, and assessing the development of the child
healthy baby VS. unhealthy, disorganized nervous systems
By stablizing the parents, they not only saved the marriage, but the child as well.
Teach parents first
Free family counceling, child care
Power to the Workers
The stability of the home is completely ignored, even though it is one of the greatest predictors of future success at school.
The first students are the parents!
How to create a stable home:
understanding language acquistion to the powerful need for amounts of active playtime
taking an occasional serious of marital refresher courses to ensure the stablity at home
Having to choose between your child(ren) and your career may become an obstacle.
If businesses took this seriously, they could offer Gottman's invervention as a benefit and also risk losing their best and brightest.
The biggest part of successful stress management involves getting control back into your life.
To detect stress-related problems, examining the situations where employees feel the most helpless.
The next step: Change the situation.
There are only a few possibilities that could be realized of the stress in the work force.
It's possible that findings would change the absentee rate of employees, cut down doctor visits and save their money.
This could all be solved by giving employees a way out -- not from their jobs, but from the stress they experience in them.
Stress at Work
Stress in the Home
Our chapter is on stress: Stress affects most people in some way. Acute sudden or short-term stress leads to rapid changes throughout the body. Almost all body systems the heart and blood vessels, immune system, lungs,digestive system, sensory organs and brain gear up to meet perceived danger. These stress responses could prove beneficial in a critical, live or death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic long-term stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people manage stress.
Marital stress at home can negatively affect academic performance.
Stress at home may increase absenteeism or truancy.
Not all stress is the same some hurt learning others boost learning.
Many same mechanisms cause one to shrink in horror from a predator are also used when having sex or consuming great food.
An aroused physiological state is characteristic of both stress and pleasure.
3 parts to measure stress scientifically
1) Must be an aroused physiological response to the stress and be measurable by outside party
2) Stressor must be perceived as aversive. "If you had the ability to turn down the severity of this experience, or avoid it altogether, would you?
3) Person must not feel in control of the stressor.
The more loss of control, the more severe the stress is perceived to be.
May turn into hostile environments which increase the risk of psychiatric disorders.
These disorders can harshly effect academics
The worse the conflict the greater the effect can be on performance.
Students coming from these homes are more likely to be expelled.
Stressed brains don't learn the same way. Individually, the worst kind of stress is the feeling that you have no control over the problem -- you are helpless. Emotional stress has huge impacts across society, on children's ability to learn in school and on employees' productivity at work.
Body responding to stress: massive release of energy - hormone adrenaline at work
When the sensory systems detect stress, the hypothalamus reacts by sending signals to your adrenal glands.
Fight or Flight response
Cortisol = "elite strike force" of the human stress response; second wave of our defensive reaction to stress. returns us to normalcy.
without this sophisticated system we would die.
Stress helps us manage the threats that could keep us from procreating.
Needs arise, nothing that has to do with age.
Our stress responses were shaped to solve problems that lasted not years, but for seconds.
These days stress is measured by hours, days and sometimes months with hectic workplaces, screaming toddlers, money problems, etc.
Terror and Titillation
Flooding the System
(picture from Google.com)
Stress is responsible for more than half of the 550 million working days lost because of being absent.
Stress effects healthcare and pension costs.
Stressed employees tend to be late to work and avoid going to work.
Prolonged stress > Depression > Alters thinking ability.
Elevates blood pressure, increasing risk of heart attack, and stroke.
Altered thinking can affect a business greatly.
Stress attacks the immune system, which increases employees chances of getting sick.
Out-of-control stress is bad for some people
