Multiple Choice

Which of the following statements is true of stress and the immune system?

Acute stress can temporarily boost the immune system, but chronic stress suppresses it.

Chronic stress leads to a permanent increase in white blood cell count.

Stress has no significant impact on the immune system.

Chronic stress can enhance the immune response by increasing the production of antibodies.

Verified step by step guidance

Understand the relationship between stress and the immune system: Stress can have varying effects on the immune system depending on its duration and intensity.

Identify the effects of acute stress: Acute stress, which is short-term, can temporarily enhance the immune system by activating the body's fight-or-flight response, leading to a temporary increase in immune activity.

Examine the effects of chronic stress: Chronic stress, which is long-term, can suppress the immune system by continuously releasing stress hormones like cortisol, which can inhibit the immune response.

Evaluate the statement about chronic stress and white blood cell count: Chronic stress does not lead to a permanent increase in white blood cell count; instead, it can lead to immune suppression.

Consider the impact of stress on antibody production: Chronic stress does not enhance the immune response by increasing antibody production; it generally suppresses immune function.
