According to stress research pioneer richard lazarus (1966, 1993), it is and not stress that causes problems for people.

It is subjective and not objective stress that causes problems for people. Richard Lazarus is a theoretician who developed the Cognitive Appraisal Theory.

That is why stress is a subjective assessment, that is, a personal interpretation of what happened.
