When we talk about being "hypersensitive to" something, it usually means having an exaggerated or extreme reaction to it. There are many synonyms we can use to describe this concept, such as oversensitive, ultra-sensitive, touchy, reactive, easily affected, highly strung, and thin-skinned. These words all describe a tendency to react more strongly than most people to things like criticism, rejection, or sensory stimuli. They can also refer to a heightened awareness of one's own emotions or physical sensations, which can sometimes be overwhelming. Using these synonyms can help us be more precise in our language and better convey the nuances of hypersensitivity.
