How does stress impact immune system functioning?

Stress can weaken the immune system, making it more vulnerable to illness and infection.

When we experience stress, our body releases cortisol, a hormone that can suppress the immune system's response to infection and inflammation. This means that if we are exposed to a virus or bacteria, our immune system may not be able to fight it off effectively, increasing the risk of illness.

Chronic stress can also lead to inflammation, which can damage tissues and organs in the body. This can increase the risk of developing chronic diseases such as heart disease, diabetes, and autoimmune disorders.

Stress can also impact our behaviours and lifestyle choices, which can further weaken the immune system. For example, when we are stressed, we may be more likely to engage in unhealthy behaviours such as smoking, drinking alcohol, and not getting enough sleep. These behaviours can all have a negative impact on the immune system.

Overall, it is important to manage stress in order to maintain a healthy immune system. This can be done through techniques such as exercise, meditation, and relaxation techniques. By reducing stress levels, we can help to strengthen our immune system and reduce the risk of illness and disease.
