A spider and public speaking fear specialist provides his top 3 tips for overcoming any fear.

Fear of spiders and fear of flying on a plane are two different types of phobias.

One phobia specialist asserts that all of them are irrational.

An irrational fear of a harmless substance is known as a phobia, according to Christopher Paul Jones, a London-based phobia specialist with a clinic on Harley Street, as stated in an interview with CNBC Make It.

Our amygdala, a part of the brain that processes emotions, is primitively hardwired to fire off when we experience danger. As a result, we typically respond by either getting angry and punching the thing, running from the thing, or hiding from it.

However, a phobia is when that response is to something that isn't dangerous, Jones said.

A range of phobias, including a fear of water, heights, germs, needles, and failure, have been treated at Jones' clinic.

Through a conditioned response like Pavlov's dogs experiment, phobias develop. In this experiment, Russian neurologist Ivan Pavlov rang a bell every time he fed his dogs. As a result, the dogs started to salivate when they heard the bell ring, associating it with food.

"Jones stated that people often experience the same response when they encounter something that they have previously associated with danger. This is typically the case with phobias, where a past experience has linked danger to a specific object or situation. As a result, whenever the person thinks about that object or situation again in the future, their brain automatically triggers the old response."

Jones' recently published book "Face Your Fears" provides readers with exercises to help them conquer their fears. He shared his top three tips for overcoming any fear with CNBC Make It.

Challenge your perception of the object

Jones suggested that a simple technique to overcome your fear is to rethink the object you fear.

The "Harry Potter" effect refers to a scene in the "Harry Potter and the Chamber of Secrets" movie where students confront their fears and employ magic to transform them into something amusing.

When you envision a spider, people typically depict it as large and in close-up. However, if you picture it as small, black and white, or imagine it on roller skates, smoking a little cigar, and dancing with a little hand, you'll experience a different emotion.

He suggested using the same technique on your inner dialogue.

If you're thinking "Oh my god, I'm going to get scared" or "This is going to make me jump" or "What if I embarrass myself?", imagine that inner dialogue as if it was Mickey Mouse or Donald Duck, with a squeaky voice, and it will take all the power out of it.

Jones stated that in the moment, the fear will seem "sillier and less realistic."

Give yourself a hug

Giving yourself a hug can be a simple and effective way to comfort yourself when confronted with your phobia, according to Jones.

Hugging yourself in this way releases the same chemicals as if you were hugging someone else or if someone else was hugging you, he explained.

"When you release oxytocin and other chemicals while engaging in relaxing or self-soothing activities while imagining a frightening thing, your brain struggles to maintain both emotions simultaneously, resulting in a reduction of fear."

Recondition your brain

Pavlov's dogs experiment demonstrated that the brain can be conditioned to fear something, and Jones argued that it can also be reconditioned to undo that fear.

Jones explained that visualizing happy, calm, or laughing moments in your mind and performing a unique action at the peak of the emotion, such as squeezing your fist and thinking about happy times, can create an artificial Pavlovian response conditioning.

If you squeeze your wrist while facing a specific fear, it will transport you back to happy memories and reduce the emotional intensity of the fear, as he stated.

He suggested some fast actions to break the old routine.

He stated that we can transform our internal images, dialogue, and emotions into a humorous film by changing the music and pacing, similar to how people edit horror movies on Reddit and YouTube.
