Stress - All you need to know about its causes and effects


Stress is a natural physical and mental reaction to life experiences, challenges, and other situations. Everyone expresses stress from time to time. Anything from everyday responsibilities like work and family to serious life events such as a new diagnosis, war, or the death of a loved one can trigger stress. For immediate, short-term situations, stress can be beneficial to your health. It can help you cope with potentially serious situations. Your body responds to stress by releasing hormones that increase your heart and breathing rates and ready your muscles to respond.


Stress is somewhat necessary for our day to day lives but in a limited and healthy amount, as it increases human arousal and affects performance, it motivates us and helps us to achieve the goals we set for ourselves, during a stressful situation we respond by allocating all our resources and by mobilizing all our efforts towards the stimulus, which helps us in overcoming the situation easily.



Stress is like electricity, it gives us energy, increases human arousal and performance, however, if the electric current is too high it can fuse bulbs, damage applications, etc, in the same manner, high stress can produce unpleasant effects and cause our performance to deteriorate. On the other hand, too little stress can lead to a person being listless and low on motivation, which may cause decreased performance levels, hence it is important to remember that stress is not inherently bad or destructive.

Eustress: This word refers to the optimum level of stress which is actually beneficial for a person and helps the person in achieving peak performance and managing minor crises.


Distress: Eustress may sometimes turn into distress, and it is ‘distress’ that causes the actual wear and tear of the body.


Thus, stress can be defined as the pattern of response an organism makes in response to the stimulus event that disturbs the mental and physical equilibrium of the person and exceeds the person’s ability to cope.
