Psychoneuroimmunology introduced the idea that stress, if chronic impairs immune function, enabling greater susceptibility to illnesses. However, during a TEDx talk, Kelly McGonigal pushed this idea -introduced by psychoneuroimmunology – further by insisting and referencing various studies that show that stress is in fact not the enemy, and that while certain body states are altered while stressed, it’s the belief that one has about stress that is said to affect one’s health status. I can’t give away too much but I can certainly suggest that you watch this incredible speech to further understand how the stress system benefits the body as opposed to marring it.
