Question
COMM 3590 Unit 5 AS: Technical Presentation
AS1 Instructions: You are to develop a technical presentation that helps the audience understand a complicated concept or process. While many informative presentations are demonstrations (where the speaker explains how to do something), or accounts (where the speaker explains why something is the way it is), the technical speech is more varied and more complex.
Specifically, your speech should focus on helping people understand: a) what something means (a difficult concept), b) how something functions (difficult structures or processes), or, c) some combination of the two.
A technical presentation focuses a lot of effort on a small, but complicated, point rather than covering a larger idea more broadly. If you’re not sure whether your topic constitutes a true technical presentation, check with your instructor prior to beginning your research.

STRESS
CAUSES OF STRESS
Stress is experienced when we perceive things as threatening when we do not believe we have what is necessary to withstand situations or what circumstances demand.
Stress can be internal or external.
Internal cognition that makes a person have fear or other negative emotions surrounding an environment such as pain and pressure which they may then perceive as stressful.
Common causes of stress include bereavement, family problems, accidents and tiresome work schedules.
DEALING WITH STRESS
Stress can be managed using various methods.
They include techniques such as avoiding people who stress you out, taking control of your environment, speaking out instead of holding stress to yourself, creating a balanced schedule and expressing your feelings instead of holding them the up.
Other proven techniques of managing stress is cognitive e therapy. This therapy involves the individual working collaboratively with therapists to develop skills for testing and modifying beliefs, identifying distorted thinking ,relating to others in different ways and changing behaviors.
Relaxation techniques are often also employed as a stress management tool. They help decrease muscle tension, lower the blood pressure and slow heart and breath rates among other benefits.
SIGNS AND SYMPTOMS
Symptoms of stress can be divided into various categories. They include; behavioral, psychological, emotional and physical.
Psychological symptoms of stress are boredom, tension, anxiety, depression, insecurity, powerlessness, isolation and meaninglessness.
In boredom repetitive work such as assembly work or many forms of administration can be immense source of boredom .Lack of variety fails to stimulate the mind and boredom and fatigue sets in.
Anxiety occurs when a person feels not being able to cope with potential problems. These problems may or ,may not arise but they feel real to the anxious person.
Depression is when an individual experiences prolonged feelings of helplessness and hopelessness .They are unhappy with their life but feel they are incapable of improving things.
HORMONAL CHANGES CHANGING DURING STRESS.
In the response to stress, the level of various hormones changes .Reactions to stress are associated with enhanced secretion of a number of hormones .
They include glucocorticoids ,catecholamine ,growth hormone and prolactin ,the effect is to increase mobilization of energy sources and adapt the individual to its new circumstances.
Cortisol is another hormone which inhibits or aggravates stress levels. Stress hormones norepinephrine and epinephrine are released in a quick burst.
They quickly dissipate after the stressful situation is over and don’t hang around to do damage. This is followed by the release of cortisol. Continuous production of cortisol has serious health implications.
Chronically elevated cortisol puts you at risk of diabetes ,high blood pressure, obesity ,heart disease, digestive disorders and infertility(Davidson,2001).
STRESS EFFECTS.
There are numerous emotional and physical effects that have been linked to stress.
Emotional effects include depression, anxiety ,heart attacks ,strokes ,immune system disturbances and hypertension.
In addition, stress can have direct effects on the skin(dermatitis and rashes), peptic ulcer and irritable bowel syndrome.
It can also contribute to insomnia and degenerative neurological disorders such as Parkinson’s disease.
Physical effects include a variety of physical symptoms
Stressed people may experience unexplained aches and pains, chest pains or difficulty in breathing.
Cognitive effects affects the way an individual reasons, or responds to situations and may also lead to sleeping problems. Difficulty with judgment and reasoning can also lead to failing to make correct decisions which can lead to loss of self confidence.
HOW STRESS AFFECTS YOUR BRAIN.
Stress begins in the hypothalamus pituitary adrenal axis(HPA).When your brain detects a stressful situation.
When your brain detects a stressful situation, your HPA axis is instantly activated and releases the hormone cortisol which makes your body instantly react.
High levels of cortisol over long periods of time may damage your brain.
Chronic stress for example increases the activity level and number of neural connections in the amygdala, the brain’s fear center.
As levels of cortisol rise, electric signals in the hippocampus, the part of the brain associated with learning ,memories and stress control deteriorate.
The hippocampus also inhibits the activity of the HPA axis ,so when it weakens, the ability to control your stress also weakens. Cortisol can also literally cause the brain to shrink in size.
CURRENT STATE OF STRESS AND STRESS RELATED PROBLEMS.
Work is the leading cause of stress among our population followed by finances and most recently modern concerns like terrorism and the state of the environment.
Young people are excessively stressed out these days .”Self-oriented “ or having high expectations of yourself and where young people have rigorous standards for others are the leading causes of stress(Bickerstaff,2007).
Stress of perfectionism can lead to eating disorders ,high blood pressure , suicidal thoughts )and depression.
It has also emerged that a mother’s stress levels directly impact to the brain development of babies. Specifically that her stress can change the neural connectivity of her unborn baby’s brain(Wheeler,2007).
CONCLUSION
Stress often occurs in response to situations that are perceived as being difficult to handle or threatening.
Each person suffers stress differently. A healthy response to stress begins quickly ; is appropriate in degree and in length and can improve motivation and productivity.
Chronic stress is a serious condition which occurs when a stressful situation is prolonged and continuous and often causes severe physical and emotional symptoms.
Some people are more prone to stress and the effects of stress include over-competitiveness, excitability, impatience, aggression and pessimism.
Stress management is an important technique is reducing stress levels in humans for sustainable brain developments.
