Approximately one in six people experience some level of discomfort when looking at circular patterns, such as those found in sponges, honeycombs, or lotus seed pods. This reaction, known as trypophobia, is not officially recognized as a mental health disorder, but it is often marked by feelings of disgust, nausea, or a tingling sensation on the skin. Common triggers include everyday items like sponges, crumpets, bubbles, aerated chocolate, and strawberries. While most people experience only mild reactions, a smaller number may find the discomfort severe enough to avoid certain images or objects. Trypophobia has become more widely discussed in recent years, in part due to social media platforms like TikTok, which have helped spread awareness through shared images and online communities. A 2024 study found that nearly two-thirds of people had learned about trypophobia through social media. However, the study also revealed that about one-quarter of those with the condition had never heard of it before, suggesting that while social media increases awareness, it may not be the cause of the condition itself. Scientists have proposed two main theories to explain the origin of trypophobia. The first, called the threat-detection hypothesis, suggests that the circular patterns people find unsettling resemble those found on dangerous animals, such as snakes, which may trigger a subconscious fear response. The second theory focuses on disease avoidance, arguing that clusters of holes may look similar to skin rashes or signs of infection, activating psychological mechanisms that evolved to help humans avoid illness. These theories suggest that the brain might interpret these patterns as potential biological threats, even when the objects are harmless. For most people, trypophobia does not require treatment, as symptoms are generally mild. However, if the condition causes significant distress or interferes with daily life, seeking professional help can be beneficial. Treatments used for specific phobias, such as exposure therapy, may help reduce symptoms. A recent study found that a single intensive treatment session targeting fear and disgust helped reduce symptoms and improved participants' ability to engage in daily activities.
