Final answer:
Jason is likely experiencing immunosuppression due to chronic stress. b) His immune response is probably dropping, making him more susceptible to illness.
Step-by-step explanation:
Given Jason's recent experiences, which include job loss, separation from his spouse due to green card issues, and the need to find new housing, it is likely that he is undergoing a period of chronic stress.
This type of stress is known to have various negative impacts on physical health, including immune system function.
Chronic stress can lead to immunosuppression, making a person more susceptible to illnesses and diseases due to a weakened immune response.
Since persistent and repeated exposure to stress can impair immune system functions and is associated with an increased risk of conditions like heart disease and susceptibility to infections, it is most likely that Jason's immune response is dropping (b).
This means that his body's defenses against disease may be compromised, and he may have higher chances of becoming ill.
Studies have shown that while short-term stress might not significantly impair the immune system in healthy individuals, long-term stress can have marked effects, causing individuals to become more vulnerable to a variety of health issues.
