A highly sensitive person (HSP) is a neurodivergent individual who is thought to have an increased or deeper central nervous system sensitivity to physical, emotional, or social stimuli. Some refer to this as having sensory processing sensitivity, or SPS for short.

While highly sensitive people are sometimes negatively described as being “too sensitive," it is a personality trait that brings both strengths and challenges.
