Emotions matter because they influence our behavior. And there is no emotional experience that has a more powerful influence on us than stress.
Stress refers to the physiological responses that occur when an organism fails to respond appropriately to emotional or physical threats.
Extreme negative events, such as being the victim of a terrorist attack, a natural disaster, or a violent crime, may produce an extreme form of stress known as Posttraumatic Stress Disorder (PTSD), a medical syndrome that includes symptoms of anxiety, sleeplessness, nightmares, and social witdrawal.
