Octophobia is also known as the fear of the number eight. People with such phobias may not want to do anything that involves using the number eight.1

If you are suffering from this condition, you may experience a very high amount of anxiety from just thinking of or seeing the number eight.2 In fact, your anxiety may be so intense that you may even endure a full-blown panic attack as a result of it.

Octophobia can cause a person to avoid the things they are afraid of. For instance, Someone with this condition may refuse to own eight of the same item, regardless of what it is (e.g., a spoon, book, and pen). Another example is that people with this condition may avoid living in a home that has the number eight on its address and may worry that it will get destroyed someday. 

Others would not want to wed on the 8th day of the month or the 8th month of the year (August). If the person glances at the number, they may get stunned by it, but if they gaze at it, they may panic, giving them a sense of helplessness.

Some phobias are quite well-known, such as claustrophobia3 (fear of small spaces) and arachnophobia (fear of spiders). 

However, less well-known phobias can have a similar detrimental impact on a person's life. The fear of the number eight, or octophobia, is one phobia that may not be as well-known but still has a big impact on the lives of those who experience it.

What are the causes of octophobia?

The exact cause of octophobia is not fully understood, like many other phobias. But it frequently results from a combination of environmental, genetic, and psychological elements, just like other phobias4

Childhood traumatic events involving the number eight, cultural beliefs or superstitions, or even learned behaviours from relatives who share the same fear could all play a role in the emergence of octophobia.

What are the symptoms of octophobia?

People with octophobia may experience symptoms of anxiety2 when they think about or come across the number eight.

  • Dizziness
  • Dry mouth
  • Extreme feeling of dread or terror
  • Nausea, vomiting or diarrhoea
  • Profuse sweating
  • Rapid breathing and heart rate
  • Shaking or trembling
  • Shortness of breath

People with octophobia also exhibit certain behaviours, such as:

  • They avoid looking at things like street signs, clocks, computers, phones, books, bills, or receipts that have eight on them
  • They skip school or work because of the possibility of encountering the number eight
  • They stay at home or never go out because of fear of encountering the number eight
  • These behaviours can harm a person's relationships with others, career, and education, and they can also cause depression or substance abuse

How can octophobia be diagnosed?

Diagnosing octophobia involves a thorough evaluation of the individual's symptoms, medical history, and psychological profile.

A mental health professional, such as a psychologist or psychiatrist can conduct this evaluation.

The diagnosis is typically based on the criteria described in the DSM-5, which provides the diagnostic criteria for specific phobias.5

To diagnose octophobia, a healthcare provider will look for an intense fear of the number eight that causes extreme anxiety as soon as the individual thinks about or encounters the number.

People with octophobia may fear the symbol eight as it appears written down, such as in addresses or advertisements, or they may fear objects presented in groups of eight.

It is important to note that octophobia is a rare phobia, and there are few other known phobias of specific numbers, except for the fear of numbers themselves (arithmophobia) and the fear of the number thirteen (triskaidekaphobia).

Impact of octophobia on social interactions and coexisting conditions

Octophobia can have a significant impact on an individual's daily life, limiting their activities and social interactions.

Anxiety2 associated with octophobia can interfere with education, job responsibilities, personal relationships, and daily tasks.

People with octophobia may avoid situations where they may encounter the number eight, such as social gatherings, shopping, or travelling.

Octophobia can also coexist with other mental health conditions such as anxiety disorders, 2 depression, and obsessive-compulsive disorder (OCD).6

It can impact various aspects of life, including personal relationships, job performance, and daily tasks.

It is also essential to diagnose and treat these coexisting conditions to improve the overall quality of life of the individual with octophobia.
