Psychologists Richard Lazarus and Susan Folkman scientifically defined coping as the sum of cognitive and behavioural efforts, which are constantly changing, that aim to handle particular demands, whether internal or external, that are viewed as taxing or demanding. Simply put, coping is an activity we do to seek and apply solutions to stressful situations or problems that emerge because of our stressors. Actually, the term "coping" is more associated with "reactive coping", because in general, we see coping as a response to a stressor. On the other hand, there's also what we call "proactive coping", wherein the coping response is aimed at preventing a possible encounter with a future stressor.
