The simplest description for stress I have ever heard is from Hans Selye, the Canadian physician, who first borrowed the word from engineering and applied it to a physiological process he observed in his patients. He described stress as simply the body's adaptation to change. It is how we respond whenever an internal or external event occurs.
Change can be as simple as a shift in room temperature or as destabilizing as losing one's job. Since change happens nearly every instant, we have a stress response nearly every instant. Stress is natural and necessary.
