The crucial role that astrocytes play in the formation of muscle memory may also shed light on the beneficial impact of meditation and deep breathing as a method of managing and controlling one's rage. Some research suggests that an individual is more susceptible to having feelings of depression and anxiety if he or she experiences rage on a frequent basis. Health complications become much worse if an individual represses feelings of rage. John E. Sarno believes that repressed rage in the subconscious leads to physical ailments. Cardiac stress and hypertension are other health complications that will occur when rage is experienced on a regular basis. Psychopathologies such as depression and posttraumatic stress disorder regularly present comorbidly with rage. Evidence has shown that behavioral and cognitive therapy techniques have assisted individuals that have difficulties controlling their anger or rage. Role playing and personal study are the two main techniques used to aid individuals with managing rage. Role playing is utilized by angering an individual to the point of rage and then showing them how to control it. Multi-modal cognitive therapy is another treatment used to help individuals cope with anger. This therapy teaches individuals relaxation techniques, problem solving skills, and techniques on response disruption. This type of therapy has proven to be effective for individuals that are highly stressed and are prone to rage. An emerging business is the rage room, a place where people relieve their stress by destroying objects within a room. According to psychologists, rage is an in-born behavior that every person exhibits in some form. Rage is often used to denote hostile/affective/reactive aggression. Rage tends to be expressed when a person faces a threat to their pride, position, ability to deceive others, self-deceptive beliefs, or socioeconomic status. This maladaptive conflict management strategy often stems from cognitive dissonance, most simply put, a 'no' where a 'yes' has been. Cases in which rage is exhibited as a direct response to an individual's deeply held religious beliefs, may directly be related to cognitive dissonance in relation to an individual's ability to manage the terror associated with death and dying. Many researchers have questioned whether Hindu/Buddhist concepts, such as reincarnation and nibbâna, help ease death anxieties. Coleman and Ka-Ying Hui (2012) stated that “according to the Terror Management Theory, a religious concept of an afterlife helps people manage their personal death anxiety” (949). This suggests that rage, in relation to religious ideas, may stem from an inability to manage feelings of terror.
