Stress costs the national economy $500 billion annually and leaves nearly half of all adults with health problems. Stress is caused by factors like incompetent management, ambiguity, uncertainty, workload, and expectations. It can be bad when the stress is long-term or the individual's coping mechanisms are ineffective. People may react to stress through alarm, resistance, or exhaustion. However, individuals can build resiliency to stress through developing hardiness, social support, self-care, goal alignment, and following their passion. Managing stress involves recognizing triggers, reframing thoughts, and using strategies like exercise, relaxation, and supportive relationships.
