Most people think that stress is always bad. Nothing can be far from truth! A little stress is absolutely necessary for our survival in this highly
competitive world! Thus, we can classify stress into two groups:
Eustress: This is the good stress which helps us to improve our
performance. For example, if there is no stress of performing well in the exams
or athletic events, students will not study harder or the athletes will not
sweat it out on the tracks. A certain amount of positive stress keeps us pepped
up to meet all challenges and is necessary for our survival and progress in
life.

Distress: When stress gets out of hand, it becomes distress, which will
bring out the weakness within us and make us vulnerable to illness. If continued
unchecked, this will lead to all the ill-effects as explained in the part 1 of
this series.
