8 Most Common Irrational Phobias (You Probably Have At Least One Of Them)

Sharing is caring!

An estimated 19 million Americans suffer from one or more phobias that vary in intensity from mild to severe. If you think you might be one of them, you likely have one of the 8 most common irrational phobias—or if you’re less fortunate, possibly more.

Thanatophobia (Fear of Death)


Thanatophobia, commonly referred to as “death anxiety,” is an intense fear of death or the process of dying. This fear can be about one’s own death or the death of someone close. It’s distinct from necrophobia, which is specifically a fear of dead things, such as corpses, or places associated with death, like graveyards.

An Overwhelming Fear of Death


While it’s perfectly normal to harbor some fears about the inevitable unknowns of death—worries about pain, loneliness, or the nature of dying—thanatophobia is characterized by a fear so overwhelming that it disrupts daily functioning. 

This might mean difficulties at work, in school, or social settings, and it could manifest physically, as with panic attacks, when death is discussed or contemplated.

How Common Is Thanatophobia?


The prevalence of thanatophobia is somewhat understated due to people’s reluctance to express their fears about death. Studies indicate that between 3% and 10% of individuals feel exceptionally nervous about dying.

Who Is Most Afraid of Dying?


Thanatophobia can strike anyone but is more prevalent in people facing serious health issues, lacking religious beliefs, or experiencing dissatisfaction with life. Other risk factors include low self-esteem, the presence of other phobias or mental health disorders, and personal connections to aging or ill loved ones. 

Interestingly, fear of the dying process tends to increase with age, while younger adults may fear the concept of death more broadly.

Death-Related Trauma and Anxiety


The origins of thanatophobia often stem from traumatic experiences related to death, such as witnessing a painful death or the loss of a close relative. Thus, individuals with thanatophobia may become excessively preoccupied with their health, constantly vigilant for signs of illness.

Symptoms of thanatophobia include an overwhelming dread or depression when thinking about death, along with physical symptoms typical of panic attacks, such as chills, heart palpitations, and nausea. 

Acrophobia (Fear of Heights)


While a certain caution around heights is typical for most, acrophobia takes this to an extreme level, impacting daily tasks and quality of life. It’s not just a mild fear of heights—it’s an anxiety disorder characterized by an overwhelming dread of heights. 

What is Acrophobia Really Like?

This fear can stem from the mere thought of being high up or actually standing somewhere elevated, those with acrophobia experience severe anxiety that far exceeds normal height wariness. 

Acrophobia can make everyday activities like climbing stairs, standing on a balcony, or using a multilevel parking garage daunting tasks.

How Many Are Afraid of Heights?


If the thought of heights leaves you feeling anxious, you’re certainly not the only one. Acrophobia is considered one of the more common phobias, with about 3% to 6% of the population affected. 

The condition is slightly more common in females and tends to develop in childhood, often becoming more evident during adolescence.

Symptoms of Height Fear


People with acrophobia may fear various situations involving elevation, such as ascending a ladder, crossing a bridge, or riding on a roller coaster. The mere thought of these activities can provoke significant anxiety, with symptoms ranging from a racing heart and dizziness to a feeling of needing to escape from the high place.

Are We Naturally Afraid of Heights?

The exact causes of acrophobia remain a bit of a mystery, but it’s thought to stem from a basic human instinct to avoid falls that could cause injuries. This natural caution might turn into a full-blown phobia after bad experiences with heights or even from dwelling too much on the risks of falling. Perhaps we humans just overthink things?

Cynophobia (Fear of Dogs)

Cynophobia is an intense fear of dogs that can severely disrupt the lives of those affected, as it may cause them to avoid situations where they might encounter dogs (regardless of how ‘cute’ they might seem!) 

This could include dodging social gatherings, skipping movies about dogs, or even staying indoors to avoid possible interactions with dogs.

How Common Is Fear of Dogs? 


While it’s hard to determine exactly how many people suffer from cynophobia, it’s known that fears related to animals are among the most common types of specific phobias. Approximately one in three people with an animal phobia specifically fear dogs.

Cynophobia Among Children and Adults


Cynophobia can occur in anyone, though it frequently develops in childhood and is notably prevalent among individuals with autism or those who have sensory or intellectual differences. 

What Triggers Dog Phobia?


If you’re a dog lover, you might be surprised at how easily someone with a fear of dogs can become anxious. Common triggers for this phobia include seeing a dog, hearing a dog bark, or even seeing images of dogs in media.

The Severe Symptoms of Cynophobia


Symptoms of cynophobia are severe, including panic attacks, screaming, crying, headaches, dry mouth, dizziness, nausea and vomiting, heart palpitations. and feelings of intense dread or danger when thinking about or encountering dogs.

How Cynophobia Develops


The causes of cynophobia are believed to be a combination of genetics, personal history, and environmental factors. A traumatic experience with a dog, such as being chased or threatened, can significantly contribute to developing this phobia. 

Claustrophobia (Fear of Confined Spaces)


Claustrophobia is defined as an intense fear of confined or enclosed spaces, significantly impacting a person’s functioning in daily activities like work or school. For someone with claustrophobia, common settings such as tunnels, elevators, or airplanes can trigger overwhelming anxiety.

This kind of fear goes beyond normal discomfort—it can disrupt concentration and disturb sleep with persistent worries about being trapped. 

How Common Is Claustrophobia?


This phobia is more common than you might think, as a significant number of people dislike being in enclosed places. Claustrophobia impacts around 12.5% of people, often involving fear of multiple confined environments. 

It’s more prevalent in women and usually develops in childhood or adolescence.

Claustrophobia Triggers


If you suspect you might have claustrophobia but aren’t certain, pay attention to how you feel in enclosed spaces. Typical triggers for claustrophobia include tight or crowded places like small cars, caves, MRI machines, and rooms that feel sealed off or airless. 

Physical and Emotional Symptoms


The phobia manifests through both physical and emotional symptoms similar to a panic attack: sweating, shaking, rapid heartbeat, and even feelings of dread or fear of losing control.

What Causes Claustrophobia?

The origins of claustrophobia are not entirely clear, but they may be linked to traumatic incidents where an individual was confined or had limited space to move. This could be a childhood experience or an event later in life, like getting stuck in an elevator. Exposure to a parent’s similar fears can also play a role in developing this phobia.

Trypophobia (Fear of Holes)


Trypophobia is a condition marked by an intense aversion or disgust toward objects with patterns of small, clustered holes—like honeycombs, sponges, seed-filled fruits like strawberries and kiwi, and lots of other holes. 

Although trypophobia was only named in 2005, it’s believed that up to 17% of people may experience some form of this aversion. Are you one of them?

How Media Shaped Fear of Holes


Interest in trypophobia surged after media coverage about reactions to smartphone designs featuring clustered camera lenses and exposure through the TV show American Horror Story: Cult, which highlighted the condition.

The Unique Discomfort of Trypophobia


Unlike typical phobias that involve fear, trypophobia centers around repulsion and discomfort. The closer one is to the triggering pattern, the more intense the reaction can be. While not everyone with trypophobia fears holes, the triggers are wide-ranging, from the holes in bread and bagels to the skin textures of reptiles or the soles of shoes. 

What Causes Fear of Holes?


Theories about its origins suggest a possible evolutionary basis, where the brain links hole patterns with potential dangers like venomous animals. Another theory proposes that holey patterns demand more energy and oxygen from your brain, which can trigger feelings of distress. 

This response might also be associated with obsessive-compulsive disorder (OCD).

What Happens When Trypophobia Strikes?


Symptoms of trypophobia are primarily physical and emotional, including chills, nausea, rapid breathing, and an overwhelming feeling of disgust or terror. 

Who would have thought holes could have such a powerful impact?

Arachnophobia (Fear of Spiders)


Arachnophobia, the fear of spiders, is a particularly intense phobia that can significantly impact daily life. For those with this fear, even the thought of spiders or their webs can trigger anxiety. This anxiety intensifies with proximity to spiders, often disrupting concentration and sleep with persistent thoughts about these creatures.

How Common Is Arachnophobia?


Interestingly, arachnophobia affects roughly 3% to 15% of people worldwide and tends to be more prevalent among females. While it can emerge at any age, it typically develops during childhood or adolescence.

Symptoms of Spider Phobia


The symptoms of arachnophobia mirror those of general anxiety or a panic attack. Physically, it might manifest as sweating, shaking, a rapid heartbeat, or even trouble breathing. Emotionally, it can lead to distress signals such as crying or panic-driven behaviors like avoiding places where spiders may be present.

Avoiding Spiders at All Costs


Behaviorally, those with arachnophobia might avoid outdoor activities or decline social invitations if there’s a risk of encountering spiders. Extreme reactions can include screaming or freezing when a spider appears. 

This phobia can stem from a traumatic encounter with spiders or even from witnessing a parent’s fear of spiders.

Aerophobia (Fear of Flying)


Aerophobia, also known as aviophobia, is the profound fear of flying that affects approximately 25 million adults in the U.S. alone. 

While many might assume this fear is rooted in the risk of an airplane crash, it often centers more on the anxiety experienced during flight, such as during take-off, landing, or while simply thinking about being confined on an airplane.

How Aerophobia Develops

This phobia typically impacts individuals between the ages of 17 and 34, a period marked by significant life milestones like graduation or starting a family. Interestingly, some may have flown comfortably for years before suddenly developing aerophobia. 

Common Fears Among Flyers


Common triggers include both the physical aspects of flying and external influences like news stories about flight-related incidents or general fears about onboard safety, such as fire or illness.

Avoiding Flights Due to Fear


Symptoms of aerophobia can lead to severe avoidance behaviors, with individuals opting out of air travel altogether, which can affect personal and professional life. This could extend to avoiding any media related to flying or obsessively gathering information about flight safety.

The Physical Toll of Aerophobia


Physically, aerophobia can trigger panic attacks, presenting with symptoms like chills, nausea, excessive sweating, and heart palpitations. These intense reactions underscore the complex nature of this phobia, which can be exacerbated by other fears such as acrophobia (fear of heights) or claustrophobia (fear of confined spaces).

Ophidiophobia (Fear of Snakes)


Ophidiophobia represents an intense fear of snakes that extends beyond simple discomfort, profoundly interfering with an individual’s daily life and sense of security. It may manifest in avoiding certain locations, experiencing panic at the mere mention of snakes, or engaging in extensive measures to avoid any potential contact with these reptiles.

Is Your Fear of Snakes Justified?


While a general wariness of snakes is quite common due to their portrayal in media and folklore as dangerous or sinister, ophidiophobia is particularly intense and pervasive. In the U.S., specific phobia disorders affect about one in ten adults and one in five teenagers at some point, with ophidiophobia being among the most prevalent.

What Causes Fear of Snakes?


This fear can be linked to various causes, such as learned behaviors from family or friends, a family history of anxiety disorders, cultural superstitions, or even traumatic encounters with snakes. 

Ophidiophobia often coexists with other phobias, such as herpetophobia (fear of all reptiles) and ranidaphobia (fear of frogs), reflecting a broader apprehension toward reptilian creatures. 

Symptoms of Snake Phobia


Symptoms of this phobia include severe anxiety or panic attacks upon seeing or thinking about snakes, characterized by dizziness, nausea, sweating, and rapid breathing.

Despite the recognition of the fear’s irrational nature, those affected find it nearly impossible to control their reactions,
