The word stress implies an experience of negative emotions that comes in the wake of anticipated physiological, biochemical, cognitive, and behavioral changes that work towards either changing the stressor or adjusting its effects. Stress has been defined as “the pattern of physiological reactions that prepares an organism for action.At some point, nearly everyone encounters stressful life events: the death of a loved one, the loss of a job, an illness, or a relationship downward.When genetic, biology, and stressful situations come together, depression can result. Stress has its own physiological consequences. It triggers a chain of chemical reactions and responses in the body. If the stress is short-lived, the body usually returns to normal. But when stress is chronic or the system gets overdrive, changes in the body and can be long-lasting.
