Oversensitivities can be described using various synonyms such as hypersensitivity, hyper-reactivity, or overreactions. Hypersensitivity refers to an exaggerated response to a stimulus that is not usually perceived as harmful or painful. Hyper-reactivity, on the other hand, is a heightened response to an external factor that can trigger an allergy or sensitivity. Overreactions, as the name implies, are an exaggerated response to a situation, often causing unnecessary tension, anxiety, or fear. Other synonyms for oversensitivities include over-sensibility, oversensitivity, and hypersensitiveness. All these words convey the same meaning, but they differ in the degree of emphasis on the over-exaggeration of the response.
