Stress can be defined as a mental, emotional and physical
strain on the body. Once physical, cognitive and emotional arousal occurs
behaviours change. Stress is the physical and
psychological process of reacting to and coping with events and situations
that place pressure on a human being.
Stress reactions can be viewed as a survival mechanism.
It may then serve the function of self-preservation (protection) in
a threatening situation, enabling one to:
|
|
concentrate full attention on a particular threat |
|
|
mobilize maximum physical energy |
|
|
prepare for action in order to respond to the threat |
