'''Stress''' is a state of increased alertness of the body. It is a psychological and physiological response to events that could threaten us. As we’ve evolved, the human stress response has saved our lives. The "fight-or-flight" stress response of the body involves a cascade of biological changes that prepare us for emergency action. Today, we turn on the same life-saving physical reaction to cope with intense, ongoing stressors - and we can’t seem to turn it off.
