This document discusses stress, including its causes and effects on health. It defines stress as a physical, social, or mental event or condition that requires coping. There are two types of stress: eustress, which are positive stressors that allow personal growth; and distress, which are negative stressors that cause strain. In response to stress, the body enters a fight-or-flight state where heart rate, breathing, blood pressure and blood sugar increase, giving a burst of energy. Long-term stress can increase risks of heart disease and decrease immunity. The document recommends reducing stress through assessing stressors, changing reactions, learning to cope, exercise, relaxation, diet, time management and support groups.
