Stress is associated with a set of experiences and changes so broad and diverse that it can be difficult to quantify and even identification psychology defined as the nervous system response to an event or a situation that is perceived as a threat, this response mechanism is known as fight / flight, as the body secretes hormones to feel fear (such as adrenaline) provides the body with the physical power to face danger or flee.
According to the RAE define stress. (Of theingl. Stress). and the stress caused by overwhelming situations that cause or psychosomatic reactions sometimes serious psychological disorders.
People often speak of stress as a destructive and pernicious ailment for health, but not always. According to the Canadian specialist Hans Selye stress compared with body temperature: only when the temperature rises above normal may be considered disturbing. also every person, throughout his life has a certain ability to adapt to cope with their environment, and this amount of stress can be considered normal. but if you face too many problems, or changes, both positive and negative, if it remains in a state of continuous tension, if you overtake the threshold of resistance, this ability ends up exhausted, stress increases excessively and disorders arise.
According to Peter Nixon (Cardiologist) who developed a graph called human function curve to show how it improves the performance of a person in a state of stress (or arousal). however, after widening to an optimal point to highlight the point of fatigue called performance drops rapidly. He concluded that a certain amount of stress or healthy tension, it is even practical, as it provides the impetus or the impetus to tackle and complete tasks in our daily lives.
If that degree of stress or excitement, life would be dull and tedious and would not reach big goals. A moderate stress activates adrenaline, which prepares us to face new challenges. in fact many people claim to be more efficient when working to tight deadlines.
the experience of stress can be used used in a positive way for better understanding. since having it is inevitable to some extent, learn to handle stressful situations can be considered a valuable lesson.
people living protected from stress tend to react in a negative exacerbated and when they finally encounter such situations.
But the line between healthy and harmful stress is extremely thin. usually people underestimate the stress level we suffer and we believe we can continue to work efficiently for longer than it’s really capable (the cardiologist Nixon calls this attitude intentional performance, as opposed to actual performance).
According to general activation syndrome of Selye, the individual if you suffer chronic stress for a longer or shorter period occurs frequently elevated to stress hormones and is vulnerable to fatigue and illness. so it is vital to identify the type and degree of stress that you suffer and act accordingly.
One of the most effective ways to relieve stress is to talk about it. intimate friendships and good social relationships act as an effective buffer stress
HUMAN FUNCTION CURVE
The illustration above shows how in the first phase of stress, to the left of the dotted line, referred to stress “good”, productivity increases consistently. The body and mind are in a state of “enlightenment” during which issues are resolved effectively. Both at work and in daily life increases the productivity of large upward without abruptness.
But to get to the top of the dotted line, (THE HUMP), which is different in each individual, a sudden drop appears unstoppable if circumstances or defense mechanisms do not change. So start to show negative symptoms, fatigue first, after health problems and finally, if no correction applied, comes the “breakdown”, the breaking point where you can no longer “give anymore” when symptoms of anxiety can become symptoms of depression and the mind is responsible for forcing the body to give up the fight.
It is during this period of “down” when symptoms of stress are added the consequences of those committed by the mere fact of “download other” some underlying tension, or insulated to avoid facing problems. The body and mind have been all the time ready to opt for the only options offered by nature: the “fight / flight” reactions resulting in cognitive, emotional, physical and behavioral: the so-called symptoms of anxiety or stress.
