Can stress weaken an immune system and increase disease susceptibility in animals?

1. True

2. False

The correct answer is: True

Stress can weaken the immune system in animals, making them more susceptible to diseases. When an animal experiences stress, it triggers a physiological response that releases stress hormones, primarily cortisol. Elevated levels of cortisol can suppress the effectiveness of the immune response, inhibiting the ability of the body to fight infections and diseases. Chronic stress can lead to a state of immunosuppression, where the animal's ability to defend against pathogens—such as bacteria, viruses, and parasites—is compromised. This increased vulnerability is why stressed animals may exhibit higher incidences of illness, slower recovery from disease, and, in some cases, a reduced ability to respond to vaccinations. Understanding the relationship between stress and immune function is critical in animal care and health management. It highlights the importance of providing a low-stress environment and appropriate mental and physical stimulation to promote overall well-being and health in animals.
