Answer:
Reducing her immune response.
Explanation:
It's often overlooked that various factors such as smoking, alcohol use, poor diet, stress, and others can weaken our immune system.
Essentially, stress can influence hormonal and cellular activities in the body, either increasing or decreasing them, leading to dysfunction. In other words, stress can adversely affect the immune system, resulting in a diminished response to infections and harmful agents.
