In order to choose a perfect title for your essay I recommend you to write a list of its key ideas and then try to shorten them. It's also important to keep in mind the style of your essay. If it's written for a univeristy magazine you can try some informal titles that will maybe refer to events familiar to the students. Rhetoric questions sometimes work well too, like in: what really causes stress?

I think "Stress in the university life " is a good one..

THE SAVORY STRESS. i think thats smart because the study stress is a good thing that we can use it to enthusiasm us to increase our work and successively improve ourselves.
