Fear is a natural part of the human experience—it’s what protects us against potential dangers. Yet, some common fears can seem irrational. These phobias can disrupt daily life and make ordinary situations feel overwhelming. Here, we’ll explore 21 irrational phobias that most people have.
Heights
“Around a third of the population” has an intolerance or fear of heights, according to Forbes. Even standing on a high balcony or looking out from a tall building can make people’s stomachs churn, and this fear often stems from the natural instinct to avoid falling, which could lead to serious injury or death.
Spiders
Arachnophobia, being afraid of spiders, affects many people around the world, but these eight-legged creatures can invoke a sense of dread that seems disproportionate to their actual threat. Even small, harmless spiders can send people running for cover, thanks to their quick, unpredictable movements and their tendency to appear suddenly.
Snakes
Another widespread phobia is anxiety over snakes, or ophidiophobia, often brought on by their slithering motion and sometimes venomous nature. Even pictures or videos of snakes can cause discomfort for those with this fear. While encountering a snake in the wild can be genuinely dangerous, the panic often extends to harmless snakes and even non-threatening environments like zoos.
Flying
Despite being one of the safest modes of transportation, many people have distress about flying, known as aviophobia. The thought of being thousands of feet in the air, coupled with the occasional turbulence, can cause significant anxiety—and for some, the fear is rooted in a lack of control, while others worry about the potential for mechanical failures.
The Dark
Often starting in childhood, nyctophobia, the fear of the dark, is a common phobia that can persist into adulthood—darkness, after all, can make familiar places feel threatening, as it obscures our surroundings and heightens other senses. The imagination tends to run wild in the dark, conjuring up images of hidden dangers or lurking threats.
Public Speaking
Glossophobia, panic about public speaking, is one of the most prevalent phobias, stemming from the idea of standing in front of an audience and delivering a speech. People fear making mistakes, being judged, or embarrassing themselves in front of others. This phobia can also manifest physically, with symptoms like sweating, shaking, and a racing heart.
Clowns
The dread of clowns might seem odd, but coulrophobia is something many of us can relate to: their exaggerated features, makeup, and unpredictable behavior can be unsettling rather than entertaining. For some, this fear stems from childhood experiences, while others may be influenced by negative portrayals of clowns in media and horror films.
Enclosed Spaces
Elevators, small rooms, crowded trains, and even MRI machines can trigger claustrophobia: the fear of enclosed spaces. The sensation of being trapped with no easy escape can cause panic and anxiety, and claustrophobia can interfere with daily activities and limit opportunities, such as avoiding public transportation or certain medical procedures.
Germs
Germophobia, or mysophobia, is to be afraid of germs and contamination, and this fear can lead to excessive hand-washing, avoiding public places, and an over-reliance on sanitizers. People with germophobia are constantly worried about getting sick or coming into contact with bacteria, and while hygiene is important, germophobia can become all-consuming, affecting daily life.
Thunder and Lightning
A fear common among both children and adults is astraphobia, or being terrified of thunder and lightning, which is understandable thanks to the loud, unexpected sounds of thunder and the sudden, startling flashes of lightning. The panic often peaks during severe weather conditions, causing people to seek shelter and avoid going outside.
Dogs
Being afraid of man’s best friend is more prevalent than you might think. This worry, cynophobia, can range from a slight unease to a debilitating anxiety that prevents individuals from going near dogs. Past traumatic experiences, such as being bitten or chased, often contribute to this phobia.
Needles
The thought of a needle piercing the skin can cause significant anxiety, leading some to avoid necessary medical care when they have trypanophobia, the fear of needles. This phobia can cause physical changes, with symptoms like dizziness, sweating, and even fainting at the sight of a needle.
Holes
Triggered by clusters of small holes or bumps, like those found in honeycombs, lotus seed pods, or even certain patterns on the skin, people with trypophobia (being scared of holes) experience discomfort, nausea, and anxiety when exposed to these images. The exact cause of this phobia is not well understood, but it is believed to be related to an aversion to potential hazards or diseases.
Bridges
Traveling can be tough for those with gephyrophobia, being anxious around bridges; crossing a bridge, especially a high or long one, can induce panic attacks and severe anxiety, and this fear often stems from worries about the bridge collapsing or the person falling off. Even though modern bridges are designed with safety in mind, the sheer height and open space can be overwhelming.
Hospitals
Nosocomephobia, the fear of hospitals, can be particularly distressing. Hospitals are associated with illness, injury, and death, which can make visits highly anxiety-inducing, and the sterile environment, the smell of disinfectants, and the presence of medical equipment can all trigger panic.
Balloons
Being afraid of balloons might seem unusual, but globophobia is more common than you might expect. The unpredictability of balloons popping can cause significant anxiety, and for some, the sight of balloons alone is enough to trigger a fear response. This phobia can be particularly challenging during celebrations and parties.
Mirrors
Spectrophobia, being wary of mirrors, can make daily life quite challenging, and it’s often thanks to superstitions or horror stories involving mirrors, leading to dread about seeing something supernatural in the reflection. For some, it’s about confronting their own image, which can be unsettling. Avoiding mirrors can be difficult, as they are common in bathrooms, bedrooms, and public spaces.
Birds
Varying in intensity from discomfort around birds to debilitating fear, ornithophobia might originate from a traumatic encounter, such as being pecked or attacked by a bird. The flapping wings, sharp beaks, and sudden movements of birds can be alarming. For those with ornithophobia, even harmless birds like pigeons or sparrows can cause discomfort.
Vomiting
People can even be afraid of vomiting, too; also known as emetophobia, those with this phobia go to great lengths to avoid situations where they might vomit or see others vomit. This can include avoiding certain foods, public places, or even social interactions. The fear is not just about the act of vomiting but also the associated loss of control and the potential for embarrassment.
Dolls
Often linked to their lifelike appearance and the uncanny valley effect, where something is almost human but not quite, pediophobia is exacerbated by horror movies and stories featuring creepy or haunted dolls. For those with pediophobia, even innocent-looking dolls can be terrifying, making a trip to the toy store a stressful event.
Technology
Our final irrational phobia can be particularly challenging in today’s digital age: technophobia, being afraid of technology. People with technophobia worry about their ability to use technology correctly, the potential for their malfunction, or the loss of personal interaction—this includes things such as smartphones and computers, the internet, and artificial intelligence.
