A “highly sensitive person” (HSP) is someone who has a heightened sensitivity to the world around them, including emotions, sensory experiences, and external stimuli. HSPs may be more affected by things like loud noises, strong smells, or bright lights than other people, and may also be more prone to feeling overwhelmed or overstimulated in busy or chaotic environments.
