Defining stress isn't easy. Professionals who’ve spent most of their lives studying stress still have
trouble defining the term. As one stress researcher quipped, “Defining stress
is like nailing Jell-O to a tree. It’s hard to do!” Despite efforts during the
last half century to assign a specific meaning to the term, no satisfactory
definition exists. Defining stress is much like defining happiness. Everyone
knows what it is, but no one can agree on a single definition.
”Sorry, but I really need a definition”
Perhaps
you always began your high-school English essays with a dictionary definition
(“Webster defines tragedy as . . .”), and you still have to start with a
definition. Okay, here’s the scientific definition:
Stress
describes a condition where an environmental demand exceeds the natural regulatory
capacity of an organism. Put in simpler terms, stress is what you experience
when you believe you can’t cope effectively with a threatening situation. If
you see an event or situation as only mildly challenging, you probably feel
only a little stress; however, if you perceive a situation or event as
threatening or overwhelming, you probably feel a lot of stress. So, having to
wait for a bus when you have all the time in the world triggers little stress.
Waiting for that same bus when you’re late for a plane that will take off
without you triggers much more stress. This difference between the demands
of the situation and your perception of how well you can cope with that
situation is what determines how much stress you feel.
Stress causes stress?
Part
of the problem with defining stress is the confusing way the word is used. We
use the word stress to refer to the thing or circumstance out there that
stresses us (stress = the bus that never comes, the deadline, the traffic jam,
the sudden noise, and so on). We then use the same word to describe the
physical and emotional discomfort we feel about that situation (stress =
anxious, headachy, irritated, and so on). So we end up feeling stress about stress!
This can be confusing. In this book I try to use “stressor” or “stress trigger”
when referring to a potentially stressful situation or event, and “stress” for
your emotional and physical responses. But because the term is used so loosely,
I won’t be terribly consistent either. My advice? Don’t worry about it.
I really appreciate this wonderful post that you have provided for us. I assure this would be beneficial for most of the people. solution manual
