How can stress affect an animal's health?

Stress can significantly compromise an animal's health by weakening the immune system and exacerbating existing health issues. When an animal is stressed, its body activates a variety of physiological responses, often leading to the release of stress hormones such as cortisol. Elevated levels of these hormones over prolonged periods can lead to immunosuppression, meaning that the animal's ability to respond to infections or other health challenges may be reduced.

Additionally, stress can trigger or intensify existing health problems, such as skin conditions or gastrointestinal disorders, making management and recovery more complicated. This multifaceted impact demonstrates that stress is not just a behavioral issue but has profound implications for physical health as well.

In contrast, other options suggest limited or no impact of stress on an animal's health, which does not reflect the broader understanding of stress physiology. Stress is recognized as a factor that not only affects behavior but also has far-reaching consequences on overall health and well-being.
