There are different types of stress, good
and bad.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 the good stress or 'eustress' or the bad stress or
'distress'
Eustress: The Good Stress
Eustress 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: The Bad Stress
When stress gets out of hand, it becomes bad stress or distress, which will
bring out the weakness within us and make us vulnerable to fatigue and illness. If
distress is continued unchecked, this will lead to all the
ill-effects of
stress.
