Work stress!

What is stress?
Many people ask this question and I think that stress is a growing problem, disabling either in the university and at work where he has a personal cost, socially and economically very important. The costs and losses for the cost of stress are many and increasing year after year, as some articles I've read the rate of absenteeism, low productivity in companies, occupational accidents and low morale at work are some of these losses.

Stress usually starts with a set of environmental demands received by the individual, which should give an adequate response, launching their coping resources. When demand from the environment (work, social, etc.) is excessive compared to coping resources owned, will develop a series of adaptive reactions, resource mobilization, involving physiological arousal. This stress response includes a number of negative emotional reactions, of which the most important are: anxiety, anger and depression.

In my physiology classes I have learned for example that the human body has a great set of protection mechanisms for almost any situation that produces stress or affect organ function. This reaction causes the body maintain balance. The stress response is not negative in itself, but on the contrary, it facilitates more resources to deal with situations that pose exceptional.
This is because what happens to me is that many times when an activity does not generate a minimum of stress eventually becomes boring and uninspiring and consequently becomes stressful

Finally I believe that the stress in a just measure is necessary for our development nevertheless when this one becomes slightly disagreeable and we use enormous mental and organic energy we have to stop and consult a specialist.
