Verified step by step guidance

1. Understand the relationship between stress and the immune system by reviewing how different types of stress (acute vs. chronic) affect immune function.
2. Recognize that chronic stress leads to prolonged release of stress hormones like cortisol, which can suppress immune responses and increase vulnerability to illness.
3. Note that acute stress may temporarily enhance certain immune functions, but this effect is not permanent or always protective against disease.
4. Acknowledge that scientific research has established clear links between stress and changes in immune function, disproving the idea that there is no connection.
5. Conclude that stress impacts both psychological and physical health, with chronic stress having a suppressive effect on the immune system, making individuals more susceptible to illness.
