"The impact that emotions have on our physiology is well documented in scientific literature. We commonly refer to emotions as either being positive or negative. In reality, each emotion serves a valuable role. Emotions such as excitement, joy, anger—and even grief— help us participate in the world we live in, adding elements of texture and depth to our experiences. Anger, for example, can spur us into action in the face of injustice.
When paid attention to, our emotions can be powerful guides in our day-to-day lives. They can help us make decisions, set boundaries, and even tell us that we need to take some time to take care of ourselves. Every emotion serves as a unique brushstroke on the canvas of life. Some emotions are better categorized as renewing, such as love, joy and gratitude, while emotions such as shame, anger and fear, when prolonged and unprocessed, can become depleting and lead to a host of physiological and emotional concerns."
