Trypophobia: what it is, why clusters of holes feel so wrong, and how to cope

The holes in a sponge, bubbles gathered on a cup of coffee, a photo of a lotus seed head: the moment you see them, a shiver runs down your back and your arms start to itch. Other people seem fine, and you wonder if you're overreacting. This reaction is often called trypophobia. Here is what it means, what the symptoms look like, what researchers think may cause it and how to be less troubled by it day to day.

What does trypophobia mean? #

Trypophobia refers to strong discomfort when seeing small holes or round bumps packed together in clusters. Everyday things such as lotus seed heads, honeycombs, sponges, bubbles and seed-studded fruit can set it off. Researchers Cole and Wilkins at the University of Essex first described it in a scientific journal in 2013.

Although the name includes “phobia,” research sees the reaction as closer to disgust than to fear. A study of young people in Hong Kong (Wong et al., 2023) noted that trypophobia is not considered a form of specific phobia in existing diagnostic systems, and that the discomfort is more consistently linked to disgust sensitivity than to fear. So in this post, trypophobia is used as a common name, not a diagnosis.

Trypophobia symptoms: skin crawling, itching and nausea #

Wong et al. (2023) grouped trypophobia symptoms into three broad areas. How they show up and how strong they are differs from person to person.

• Skin reactions: itching, goosebumps, or a feeling that something is crawling on your skin.
• Mental reactions: aversion, disgust or revulsion, and feeling uneasy.
• Body reactions: feeling sick or nauseous, and sometimes finding it harder to breathe.

The body's response has been measured too. When people with high scores on a trypophobia questionnaire viewed related images, their heart rate and heart rate variability went up, but this did not happen in people with low scores (Le et al., 2020). In the same study, blood flow responses in the back of the brain's cortex were larger only in high scorers. In other words, it isn't just in your head; the body really reacts.

Why does trypophobia happen? What causes it? #

Why trypophobia happens is not yet clearly known. Researchers have proposed two main hypotheses.

The dangerous animal hypothesis: Cole and Wilkins (2013) analyzed images that trigger trypophobia and found a visual feature common in uncomfortable images (high contrast at midrange spatial frequencies). They showed that a range of dangerous animals share the same feature. The idea is that even without being aware of the link, people respond quickly and unconsciously to these simple visual features.

The disease avoidance hypothesis: Kupfer and Le (2018) suggested that clusters resemble cues of parasites or infected skin. In this view, a normally useful disgust response for avoiding disease may have become exaggerated and overgeneralized. In their experiment, everyone found disease-related clusters aversive, but only people with trypophobia also found harmless clusters aversive. How strongly people reacted was predicted by disgust sensitivity, and many described skin sensations such as itching or crawling.

The first study to compare the two hypotheses directly in an experiment (Pipitone et al., 2022) placed the patterns on images of human skin and on snakes and spiders. Discomfort changed more on the skin images, and the researchers concluded that the results support the skin disease avoidance explanation. Still, the two explanations may work together, so the cause remains an open research question.

How common is trypophobia? #

It is more common than you might think. In a household-based epidemiological study of 2,065 young people in Hong Kong (Wong et al., 2023), 17.6% scored above the threshold on a trypophobia questionnaire, and 68.1% of them were women. The rate may differ in other countries and age groups.

In the same study, people with trypophobia were somewhat more likely to have severe anxiety, depression and stress symptoms. The researchers noted, however, that these effects were generally small and that other factors played larger roles. Having trypophobia does not mean something is wrong with your mental health. If worry and tension have been growing lately, see anxiety disorder symptoms.

Coping with trypophobia: everyday ways to feel less troubled #

Most people can live with it by managing the reaction day to day. The steps below help you get swept up less when it hits and cut down on triggers you don't need to face.

1. See less of it in your feed: mark related posts as “not interested” or hide them in the apps you use often. Don't try to push through by looking at lots of images on your own.
2. Name the reaction: when your skin crawls, say to yourself, “Disgust is coming up right now.” Naming a feeling helps you see the reaction from a little distance.
3. Look away and come back to your senses: take your eyes off the screen or object and count things you can see, hear and touch around you. Our grounding techniques guide explains how.
4. Breathe out longer: if you feel queasy or short of breath, breathe out a little longer than you breathe in, a few times in a row. If you feel dizzy, stop and breathe normally.
5. Notice whether avoidance is growing: if you start avoiding more foods, places or objects, write that down. The wider the avoidance spreads, the smaller daily life can become.

If the reaction often comes with a racing heart and thoughts that won't stop, try the steps in how to cope with anxiety too. If, after seeing skin patterns, a worry like “What if I get a skin disease?” lingers for a long time, our post on health anxiety explains how to work with that worry.

Trypophobia treatment: what if it's severe? #

Research on treatment specifically for trypophobia is still limited. Wong et al. (2023) noted that case reports in children and adolescents described approaches such as cognitive behavioral therapy helping to reduce physical reactions to the images and to build new coping behaviors.

Cognitive behavioral therapy for fear or strong discomfort includes exposure, where you gradually stay with a trigger you've been avoiding, a step at a time and only as much as you can tolerate (see what is CBT). What to look at, in what order and for how long is decided together with a professional. Viewing lots of images all at once on your own may only make the discomfort worse. When the reaction is closer to disgust, therapy can also look at the thoughts and body sensations that come with it.

How strong has your anxiety been lately? An anxiety check #

The CareOps GAD-7 anxiety check is not a trypophobia test. It is a seven-item check on anxiety over the past two weeks. If worry and tension have grown along with the reaction, use it to see where your anxiety is right now. You can take it right away, with no login.

If you'd like help sorting through the discomfort #

CareOps Maeumi is an AI counseling app that runs sessions with approaches such as cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT). It helps you look at the thoughts and body sensations that come up when your skin crawls, plan small steps to take back the parts of daily life you've started avoiding, and remembers past sessions so the next one picks up where you left off.
