Question

Quizplus · Accepted Answer

Stress can lead to a reduction in lymphocyte levels, which are a type of white blood cell critical for fighting off infections. Therefore, decreased lymphocyte levels can increase the risk of respiratory infections. Increased oxytocin levels (choice A) have been associated with decreased stress and improved immune function, so it is not a likely trigger for increased risk of respiratory infections. An increase in NK cells (choice B) could actually be beneficial for fighting off infections, so it would not increase the risk of respiratory infections. Reduced cortisol levels (choice D) could potentially indicate chronic stress and impaired immune function, but it is not a likely trigger for respiratory infections.
