Stress is the body's reaction to any change that requires an adjustment or response. Prolonged or chronic stress can negatively impact both physical and mental health. Stress is linked to the six leading causes of death and causes many Americans to experience symptoms that require visits to their doctor. Common sources of stress include ordinary life events, work or financial issues, and relationships. Unhealthy behaviors like overeating, smoking, excessive drinking, and inactivity can develop as ways to cope with stress but ultimately make stress worse. Managing stress requires identifying sources of stress and making lifestyle changes like exercise, meditation, spending time with others, and learning to say no.
