What is the relationship between stress and disease? How does psychoneuroimmunology play a part in this stress-disease equation?
What will be an ideal response?
* Stressors can activate the sympathetic nervous system and release the hormones cortisol, epinephrine, and norepinephrine.
* Although these hormones help us to reduce stress, they also reduce the effectiveness of the immune system, making people more susceptible to disease.
* Long-term stressors are associated with lowered immune system functioning.
* Psychoneuroimmunology focuses on how the body defends itself against foreign substances and how psychological and physiological factors influence the immune system.
