The word phobia in the field of psychology is used to refer to that set of intense fear reactions that are often accompanied by avoidance behaviors, having generally been induced by situations (planned or real) that do not objectively justify such response forms.

There is a wide variety of types of phobias, among which in this article we will highlight megalophobia, which is the experience by a person of an intense fear of objects of large dimensions (for example, skyscrapers, large ships , airplanes, trucks, cranes). or even smaller objects than the previous ones).

In this article we will see what megalophobia is and how it could affect this type of phobia in the daily life of those who suffer from it. We will also give some brief guidelines that can be applied for your treatment.

What is megalophobia?

Megalophobia is not a very common phobia in the general population; however, there have been instances or times where many people have experienced something quite similar.

Megalophobia is the panic or fear that some people feel for large things or objectsbeing able to experience an intense sense of anxiety in situations where a remarkably large object is present (eg, passing in front of a skyscraper).

In this case, we are not talking about objects larger than normal, but by their nature large in size, such as planes, trucks or skyscrapers. The same could happen to large animals like a giraffe, elephant, or hippopotamus.

Megalophobia is An anxiety-related disorder that can significantly interfere with the lives of people with anxietyso they generally avoid any type of situation where they are exposed to large objects, so they generally have a preference for the rural environment since there are no large buildings, they can avoid traveling in oversized transports like an airplane or even experience a scary section when you pass near an oversized truck on a highway with your car.

Therefore, in the most extreme cases where you suffer from megalophobia, it may happen that a person does not want to leave their house to avoid exposure to large objects, even missing work, school or avoiding going out with friends, among others (eg high-rise buildings); this usually occurs to a greater extent in people who live in large cities.

It should also be noted that there is no single factor that can generate megalophobia, as is the case with other phobias or even other mental disorders. These factors could include genetic inheritance from a parent who suffered from a similar phobic disorder and on the other hand may also have influenced behavior learned from the past by having experienced a negative stimulus situation in the phobic past. Therefore, megalophobia could be due to the combination of the two factors, both genetics and past experiences.
