Humans seek balance in their lives. When things are out of order or imbalanced, it tends to cause problems. This is true particularly with regard to our internal state or well-being. Homeostasis refers to this tendency to maintain a balanced or constant internal state that is optimal for functioning. For example, you have a specific "balanced" or "normal" body temperature that is approximately 98.6 degrees. When there is a problem with the internal functioning of your body, this temperature may increase, signaling and imbalance. As a result, your body attempts to solve the problem and restore homeostasis; your normal body temperature.
