Una paura dei buchi: cosa scatena la tripofobia?

What is trypophobia?

If you have trypophobia you feel fear, disgust, or discomfort when you see clusters of small holes, bumps, or circles.

The term trypophobia is relatively young. It emerged from an online chat forum in 2005 when lots of participants claimed to have a shared irrational aversion to items with closely packed holes.

Trypophobia isn't recognised as an official phobia in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5)¹. This emotional reaction also doesn't seem to quite fit the definition of a phobia, which is a type of anxiety disorder - it appears that disgust, not fear or anxiety, is the main symptom in most people².

How common is trypophobia?

We may not fully understand it, but trypophobia is the most common so-called phobia in the UK³. While more research is needed to class this disgust or fear of holes as a mental disorder, studies do demonstrate that many people experience real and measurable physical reactions when shown trypophobia triggers - a quickened heart rate, for example⁴.

What are the symptoms of trypophobia?

Whether disgust or fear is your primary emotional response to seeing clusters of holes, this reaction tends to be strong enough to bring on some of the physical symptoms associated with anxiety. Phobia specialist Christopher Paul Jones explains:

"Trypophobia can make someone feel nauseous as the brain struggles to process the holes. They may also feel dizzy, may tremble, and have other symptoms of disgust or fear."

These other symptoms include:

• Aumento della frequenza cardiaca.

• Goosebumps.

• Brividi.

• Panic.

• Gagging.

• Sudorazione.

• A strong desire to get away from the image or object.

In severe cases of trypophobia, the visual of tightly packed holes may lead to a attacco di panico.

What can trigger trypophobia?

Not everyone has the exact same trypophobia triggers. For example, some people are fine looking at surfaces with holes the same size - like those on a shower head - but react when the holes are irregularly shaped - like those on a crumpet.

What is clear is that this fear of holes relates only to groups of small holes close together or repetitive patterns. A single hole in the wall or a two or three spaced out punctures on a piece of paper won't cause the same response.

This still leaves a great number of common objects and surfaces as potential trypophobia triggers. You may encounter these in real-life or experience the same reaction when they appear on TV or in trypophobic images.

Esempi includono:

• Crumpets.

• Sponges.

• Leopard spots.

• Soap bubbles.

• Honeycomb.

• Swiss cheese.

• Skin pores or lesions.

• Strawberries.

• Coral.

• Seeded breads.

• Gravelled roads.

• Pomegranates.

What causes trypophobia?

Experts agree that trypophobia is to do with how your brain processes and interprets the visual of clustered holes.

The dangerous animal theory

"Trypophobia could be caused by the brain associating closely packed holes with danger," says Paul Jones. It may be that some people have an exaggerated and over-generalised primal response to these patterns because in nature these can be a warning sign⁵ - for example, many poisonous animals have similar patterns, such as the poison dart frog and the blue-ringed octopus.

Researchers have found that animals such as these share certain spectral qualities with trypophobic images. Spectral refers to the visual aspects, like having a high contrast of colours in certain patterns, that affect how your brain interprets images⁶.

If you've ever wondered what a crumpet and a leopard have in common, this may just well be your answer.

Other possible explanations

Paul Jones points out that scientists aren't set on one clear explanation for trypophobia. Many other theories exist, and more studies are needed.

Ad esempio:

• According to Paul Jones, some scientists believe a disgust or fear of holes is triggered because of how the brain uses energy to look at these patterns.

• Another theory is that trypophobia represents another kind of evolutionary response, this time to surfaces that resemble contagious skin diseases, which sometimes show as rashes or scabs. It could be that in some people, this triggers an over-active instinct to avoid the germs that could spread serious skin illnesses, like morbillo or smallpox⁵.

One thing that is clear is that, when it comes to causes, trypophobia doesn't fit comfortably in the specific phobia category. Most phobias - for example, having a fear of the ocean - are caused by factors such as trauma, genetics, or long-term anxiety.

How to manage trypophobia

Terapia cognitivo-comportamentale (TCC) is usually the recommended primary treatment for phobias. However, Paul Jones points out that if your trypophobia doesn't appear to be rooted in a specific memory or trauma, exposure therapy may be more appropriate.

"During exposure therapy, someone is slowly exposed to the kind of things that they fear. This may start with looking at slides or pictures while a therapist provides treatment to help them cope. Then, they progress onto seeing the thing for real. For example, holding a sponge or some honeycomb," Paul Jones explains.

The idea is that the person confronts their phobias in a safe and supportive environment, in the hope that they can retrain the response of their brain when encountering their triggers.

Other management tools for phobias include:

• Anxiety medication.

• The practice of coping techniques – including esercizi di respirazione e esercizi di consapevolezza.
