Stress and its negative impact on health, derive from a mismatch between perceived environmental demands and perceived resources to adapt. Development of a proper perception to the stressor thus modifies the outcome to stress. When one is healthy one can cope with the stressful situations better - in a state of illness, or in a very sensitive state of adolescence, pregnancy and old age this coping ability gets weakened. When the situations involve momentous life events like marriage, divorce, promotion and loss of job, serious illness or the death in the family; the feeling of stress is of great order.

At some point in our lives, we have all experienced stress. However the question arises what is the actual cause of stress. Stressors are the causes of stress. These stressors may be physical or emotional. They can even be caused internally or externally. Events, situations, people, are the various stressors. The most common stressors in anyone`s life are change, death, career change. Stressors can also vary widely from person to person. What may stress you out, may not stress out someone else.

Stress can be developed in adults, teenagers as well as in children. In children it caused due to lack of happiness. It includes divorce or separation of their parents can be one of the most stressful things a child can go through. Losing a good friend, going to a new school, death, a big test, are also some very big stressors for children. While in adults stress can be caused due to various factors especially work load, family problems and competition.

Stress, either quick or constant, can induce risky body-mind disorders. Immediate disorders such as dizzy spells, anxiety attacks, tension, sleeplessness, nervousness and muscle cramps can all result in chronic health problems. They may also affect our immune, cardiovascular and nervous systems and lead individuals to habitual addictions, which are inter-linked with stress. Stress can even lead to change of appetite, sleep disturbance, headache, indigestion, palpitation, breathlessness, dry mouth or feeling of dryness in throat, butterflies in stomach, nausea, and weakness in muscles, trembling, tiredness, sweating and many more health problems.

If our personality contains following factors, it would make us more prone for the feeling of stress:
1. A strong competitive drive, often with hidden or overt aggression and hostility.
2. Intense drive to succeed, often without clearly specified goals.
3. Relentless striving for advancement, responsibility, dominance, and recognition.
4. Relatively poor ability to delegate authority and to form an identity outside the occupational environment.
5. Excessively demanding attitudes toward self and others.
6. Striving for perfection, with frustration as the frequent results.
7. Oppressive sense of time urgency, with a tendency to do as much as possible in the least amount of time, resulting in over commitment, time pressure, rushed activity, restlessness, irritability, sleeplessness, and ever) denial of fatigue.
8. Strong inner tension manifested by stilted facial expression, gestures and speech.
9. Reluctance to allow time for relaxation.
10. Excessive need for mastery of the environment, with a fear of losing control over the course of events.
11. Generally wasteful utilization of physical and emotional energizes in response to an unrealistic assessment of demands.

On the other hand if our personality is more balanced and sober we will have a competitive spirit. It is rather more important to have an optimistic approach to life. Whichever walk of life we come from the most essential ingredient needed to lead a healthy life is to make use of our talents in the rightful manner and possess positivity within us. A feeling of being under stress is more likely to occur if we find ourselves caught against our will in a certain lifestyle or if we cannot shape and amend our routine to suit our needs. Thus, our value system, which makes us contented and satisfied or discontented and dissatisfied, would have a significant influence on our feeling of being under stress.
