Stress

Stress is defined as the feeling of being overwhelmed or unable to cope with emotional or mental pressure. Any event or action that makes a person annoyed, furious, or nervous can trigger it. Chemical changes in the body caused by stress can cause blood pressure, blood sugar levels, and heart rate to rise.
