Stress management is a wide spectrum of techniques and psychotherapies aimed at controlling a person's level of stress, especially chronic stress, usually for the purpose of improving everyday functioning. Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health, such as headaches, chest pain, fatigue, and sleep problems, as well as depression. The process of stress management is named as one of the keys to a happy and successful life in modern society. Life often delivers numerous demands that can be difficult to handle, but stress management provides a number of ways to manage anxiety and maintain overall well-being.

Despite stress often being thought of as a subjective experience, levels of stress are readily measurable; using various physiological tests, similar to those used in polygraphs.

There are several models of stress management, each with distinctive explanations of mechanisms for controlling stress. Much more research is necessary to provide a better understanding of which mechanisms actually operate and are effective in practice.
