What is Triskaidekaphobia?

phobia) is the irrational fear of the number 13.
Most people with triskaidekaphobia have an immersive and
ongoing phobia / fear of the number 13.
The premise of phobia or fear of the number 13 is usually
challenging to explain, but in some cases, its causes are linked to

exposure therapy in combination with drugs.
The term comes from Greek, where tris means three, kai means and, deka means ten and phobia

Number 13 - Connotations
The number 13 wasn't always bad-famed, quite the contrary. In ancient China and Egypt, thirteen
was considered a lucky number. It is unclear when exactly did 13 become an unlucky number.
Some attribute it to the Bible, where the Last Supper was attended by 13 people, and some
speculated that the 13th person at the table was Judas, who later betrayed Jesus. However, there is no reference
to support this theory.
Another belief is that the phobia of number 13 is caused by it being an irrational number and 12
being the number of perfection.
There are 12 months in a year, 12 zodiacs, 12 hours in a clock and there were 12 tribes of
Israel.

Recent polls and studies show that around 9-10% of Americans are superstitious about the number
13. However, not all of them are triskaidekaphobes. Similar studies for other countries do not exist, however it
is prevalent in western culture mainly.
In China the number 13 is not considered bad, but instead the number 4 is considered unlucky.
The term for the fear of number 4 is called tetraphobia.
Although it may seem trivial, triskaidekaphobia is an issue that affects western societies
economically. Because of the superstition, some people delay doing business on the 13th of any month, while
statistically there are more people who do not go to work on the 13th day of any month because of this
superstition.
Friday is also considered to be an unlucky day in western culture.
Although it is unsure where the origin of the fear of Friday comes from, it may be based on the
belief that Jesus was crucified on a Friday. Thus, the number 13, associated with Friday is considered
especially unlucky.
The term for the fear of Friday the 13th is paraskevidekatriaphobia.
It is estimated that the United States loses about $900,000,000 in productivity every year

Triskaidekaphobia treatment
Although there is no 100% sure method to treat triskaidekaphobia, if you feel it affects your
life, it is a good idea to talk to your doctor who could recommend you a therapist. You will probably be exposed
to your fear and make you understand your phobia. In many instances the treatment is successful, although it may
be challenging to find a good therapist if you don't live in an urbanized area.
If you don't have access to a therapist, it is a good idea to talk about your fear and try to
understand it yourself. At the end of the day, even with a therapist involved, you are the only one who can cure
your phobia.
