Most Common Phobias, Most Unusual Phobias

Many people know the most common phobias like fear of water, but unusual phobias can be of anything, such as a phobia of books. Learn more.

Phobias are very common and are seen across all age groups. Many common phobias develop in childhood. The most common phobias include those most people have heard of such as fear of snakes or spiders; however, the most unusual phobias can be of anything, such as fear of crossing streets or fear of reading books.

A phobia is an irrational, exaggerated and persistent fear of an object or situation. For more serious phobias, such as social anxiety disorder or panic disorder with agoraphobia, many people wait more than ten years to get treatment and by then, social skills and quality of life can be greatly hampered.1

The good news is that phobia treatment, in the form of medications and/or therapy, can be very effective in dealing with both common phobias and uncommon phobias.

Most Common Specific Phobias

While a specific phobia can revolve around any object or situation, some phobias are common, particularly among certain age groups. Some of the most common phobias by type include:2

  • Animal phobia developed at an average age of 7
  • Blood phobia developed at an average age of 9

In contrast, the less common phobias, agoraphobia and claustrophobia (a fear of enclosed or narrow spaces), often don't develop until late teens or early adulthood.

Some of the most common specific phobias include:

  • Acrophobia - phobia of heights

  • Arachnophobia – phobia of spiders
  • Hydrophobia – phobia of water
  • Ophidiophobia – phobia of snakes

Unusual Phobias

In contrast to the most common phobias, which involve frequently-feared items, unusual phobias can literally be of anything in the environment or in day-to-day life.
