Stress activates the hypotalamic-pituitary- adrenal axis, increases circulating glucocorticoids, and is associated with alterations in immune functions.

Nasal lavage and peripheral blood samples were collected from healthy medical students one hour before their exams and a week later, after the declaration of results of the exams were announced.
