Stress can be defined as the brain’s response to any demand. Demands can range from any short-term or long-term life change to extreme and traumatic events. Your heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and your senses become sharper.

A healthy amount of stress can increase your strength and stamina, speed your reaction time, and enhance your focus.
