What Is a Highly Sensitive Person?

A highly sensitive person (HSP) is someone whose nervous system is more attuned to even subtle changes in their environment. They often feel deeply and notice details that others may miss. It isn’t a disorder or diagnosis, and is typically seen as a temperament trait.

It’s a trait shared by an estimated 20-30% of people. It’s associated with a tendency toward greater empathy and creativity, but may cause people to become overstimulated by stress, noise, and light. It can also be associated with neurodivergence for some people.

What It Means to Be a Highly Sensitive Person

Have you ever been told that you’re “too sensitive” or that you “shouldn’t think so much,” particularly by people who strike you as too insensitive or who you believe should think a little more? You may be a highly sensitive person, or HSP.

We’re all sensitive about certain things—that is human nature—but an HSP is understood to have a different level of sensitivity. While highly sensitive people are sometimes described negatively as “too sensitive,” this is a personality trait that brings both strengths and challenges.

“HSP isn’t a clinical diagnosis in the DSM, but many people identify with the descriptor,” says Amy Marschall, PsyD, a licensed clinical psychologist and educator with training in neurodivergence.

“Empathy is a spectrum, like many qualities, and can cause difficulty if too high or too low,” she says. “While neither is automatically bad, high empathy can be exhausting. But with appropriate support and coping skills, you can manage your empathy levels and care for yourself appropriately.”

The term highly sensitive person was first coined by psychologists Elaine Aron and Arthur Aron in the mid-1990s. Elaine Aron published her book, “The Highly Sensitive Person,” in 1996, and interest in the concept has continued to grow since then.

Signs You Might Be Highly Sensitive

High sensitivity applies across several categories. There are several traits or characteristics common to HSPs, according to the researchers who identified this personality trait:

• Being deeply moved by beauty, either expressed in art, nature, or the human spirit, or sometimes even a good commercial
• Being overwhelmed by sensory stimuli like noisy crowds, bright lights, or uncomfortable clothing
• Avoiding violent movies or TV shows because they feel too intense and leave you feeling unsettled
• Feeling a need for downtime (not just a preference), especially when you have hectic days; needing to retreat to a dark, quiet room
• Having a rich and complex inner life, complete with deep thoughts and strong feelings that go with them

The Arons also developed a highly sensitive person test, or a personality questionnaire to help people identify themselves as HSPs. It is known as Aron’s Highly Sensitive Persons Scale (HSPS).

Strengths of Highly Sensitive People

• You might be highly touched by beauty or emotionality. Highly sensitive people tend to feel deeply moved by the beauty they see around them. They may cry while watching particularly heartwarming videos. (Of course, who doesn’t cry at videos of dogs being reunited with their owners returning from overseas service?)
• You may have particularly close relationships with others. HSPs care deeply about their friends and tend to form deep bonds with people. Again, the empathy that a highly sensitive person brings to the table is a powerful tool for being a supportive friend and loved one.
• You may be grateful for the life you have. Highly sensitive people appreciate a fine wine, a good meal, or a beautiful song in a way most people can’t. They may feel more existential angst, but they also may feel more gratitude for what they have in life, knowing that it is possibly fleeting and nothing is certain.
• You empathize with others. Empathy is a tool that can promote strong relationships and a deeply fulfilling emotional life. Of course, it’s important to distinguish your feelings from others’.

How Common Are HSPs?

Highly sensitive people are thought to make up roughly 20-30% of the general population.

Highly sensitive people may benefit from finding ways to cope with the stresses they often face. This is true for those who recognize themselves as highly sensitive as well as those who have a loved one who is more sensitive than the average person.

Why Some People Are More Sensitive

What makes a person highly sensitive likely depends on a variety of factors, including evolution, environment, genetics, and early childhood experiences.

• Evolutionary factors: High sensitivity is found in at least 100 other species besides humans. Research suggests that high sensitivity is an evolutionary trait that increases the likelihood of survival because HSPs are on the lookout for potential predators or dangerous situations. Of course, constantly being on guard when there aren’t any immediate threats often results in anxiety.
• Upbringing: Research also shows that a lack of parental warmth growing up may cause a child to develop high sensitivity and carry this trait into adulthood. The same goes for negative early childhood experiences. If you experienced trauma as a child, you may be more likely to become an HSP as an adult.
• Genetic influences: Genetics may contribute to high sensitivity. Specifically, the dopamine system may play a role. It affects personality and may make some people more prone than others to becoming highly sensitive..

In addition, your genes may evolve in response to negative early experiences, making you more susceptible to becoming an HSP.

Similar Conditions and Traits

People often confuse high sensitivity with other personality traits or mental health conditions:

• Introversion: Both highly sensitive people and introverts can become overwhelmed by too much stimulation. But introverts are specifically overwhelmed by social stimuli, such as large crowds or parties. HSPs can become overwhelmed by social stimuli, too; however, HSPs are sensitive to all types of sensory stimuli, such as bright lights and loud music.
• Sensory processing disorder (SPD): It’s true that someone with SPD and someone who is highly sensitive can be averse to sensory input. The difference is that SPD can cause decreased motor function, which is not a characteristic of HSPs. In addition, SPD can cause under-responsiveness to sensory stimuli, whereas it’s characteristic of HSPs to over-respond.
• Autism: High sensitivity is not a form of autism. Again, while HSPs are overwhelmed by sensory information, individuals with autism may experience either hypersensitivity or hyposensitivity (under-responsiveness) to sensory information.
• Attention-deficit/hyperactivity disorder (ADHD): HSPs may also be mistaken as having attention-deficit/hyperactivity disorder (ADHD). While both HSPs and people with ADHD exhibit over-responsiveness to stimuli, people with ADHD also exhibit cognitive symptoms that HSPs do not, such as difficulty focusing or paying attention.

Challenges of Being Highly Sensitive

Not surprisingly, highly sensitive people tend to get more stressed when faced with difficult situations. They may also be stressed by things that may roll off other people’s backs.

Social stress is perceived as more taxing than other types of stress by most people. This kind of stress can be particularly difficult for someone who can perceive many different ways that things could go wrong in a conflict, for example, or can perceive hostility or tension where others may not notice it.

As a result, you might avoid situations that leave you feeling overwhelmed. Highly sensitive people may be more affected by certain situations, such as tension, violence, and conflict, which may lead them to avoid things that make them feel uncomfortable.

Specific things that can be significantly stressful for the highly sensitive include:

Hectic Schedules

Not everyone loves being too busy, but some people thrive on the excitement and exhilaration of a busy life. HPSs, on the other hand, feel overwhelmed and rattled when they have a lot to do in a short amount of time, even if they technically have enough time to get everything done if they rush.

The need to juggle the uncertainty of maybe not being able to make it all work and the pressure of such situations feels overwhelmingly stressful.

Expectations of Others

Highly sensitive people tend to pick up on others’ needs and feelings. They hate letting people down. Learning to say no is a challenge and a necessity for HSPs because they can feel crushed by others’ demands, especially when they fear their friends’ disappointment if they need to say no.

Highly sensitive people tend to be their own worst critics. They feel responsible for others’ happiness, or at least acutely aware of it when negative emotions are floating around.

Conflicts

HSPs may be more susceptible to being stressed by conflict. They may be more aware of trouble brewing in a relationship, including when things just feel a little off with someone who may not be communicating that there is a problem. This can also lead to misinterpreting unrelated signals as signs of conflict or anger.

Social Comparison

Highly sensitive people can be prone to the stress of social comparison as well. They may feel the other person’s negative feelings as well as their own, and experience them more strongly and more deeply than others.

They may be more aware of the possibility of improvement and upset when potentially good outcomes give way to more negative outcomes through the course of a deteriorating conflict.

They may also be more upset when they realize that a relationship is over, feeling that things could have been resolved, whereas someone else may feel there is nothing that could be done and walks away.

Tolerations

Life coaches refer to those daily energy drains that we all have as ​”tolerations,” meaning things we tolerate that create stress and aren’t strictly necessary. Distractions may feel more frustrating for an HSP trying to concentrate, and unpleasant smells in one’s environment may be felt more strongly, making relaxation more elusive.

Highly sensitive people are more easily startled by surprises. They get “hangry” when hungry—they don’t tolerate it well. In this way, life’s daily stressors often add up to more frustration for the highly sensitive.

Personal Failures

Because HSPs are their own worst critics, they are more prone to rumination and self-doubt. They may remember for quite a while if they make an embarrassing mistake, and feel more embarrassed about it than the average person would.

They don’t like being watched and evaluated when they are attempting something challenging, and can even mess up because of the stress of being watched. They are more often perfectionists but may also be more aware of the ways this stress is not inevitable and how it is affecting them.

How Highly Sensitive People Can Manage Stress

Finding ways to cope with life’s stress can be particularly helpful if you tend to be more sensitive. Much of your stress relief plan as a highly sensitive person can involve insulating yourself from too many stimuli. Put a barrier between you and sensory stimuli that feel overwhelming. Know what triggers your stress, and learn to avoid it.

• Add positivity by creating positive experiences in your schedule to insulate you from additional stress you may encounter.
• Avoid stressors like slasher movies and people who sap your positive energy, make heavy demands on you, or make you feel bad about yourself.
• Learn to say no to overwhelming demands and feel OK with it, and create a perimeter in your life.
• Set up a safe space. Let your home be a soothing environment.

Dr. Marschall says it’s critical to protect your energy, take space when needed, and connect with people who get you and support your needs.

Being a highly sensitive person means you are more likely to feel things deeply, whether those things are positive or negative. While the highs can be joyous, the lows can present challenges that can affect your stress levels, relationships, and ability to cope. Make a plan for managing your feelings in difficult situations to avoid becoming overwhelmed.
