Sensitization refers to an increased response to a stimulus following exposure to a strong or noxious stimulus. When an individual experiences sensitization, the nervous system becomes more responsive to certain stimuli, often leading to a heightened reaction. This phenomenon can occur in various contexts, such as pain responses or heightened emotional reactions after traumatic experiences. Sensitization can influence behavior by making individuals more vigilant or reactive to certain environmental cues, which is a protective mechanism in the face of potential threats.
