HSPs are people who possess a combination of acute sensory and emotional awareness. They can be easily overwhelmed when they’re over-stimulated, or can notice small changes in a room before anyone else. They can easily tap into their emotions, but are also astute and perceptive individuals. They may feel out of place in a society that doesn’t tolerate or accommodate their heightened sensitivity, but they’re highly capable people.
Our nervous systems are wired to be more sensitive than most others. As a result, they experience increased arousal as a reaction to various stimuli within their environment; this is the defining trait of a Sensory Processing Sensitivity: overarousal. According to Elaine N. Aaron, Ph.D, the psychologist who discovered the trait and coined the term “Highly Sensitive Person” in 1991, says, “The difference in arousability means that HSPs notice levels of stimulation that go on observed by others.” This of course, results in the personality trait of being highly sensitive.
