Why do some individuals suffer from fear of the dark?

Many adults share the fear of the dark held by the majority of children.
Let’s call it nyctophobia, or fear of the dark or something, because it affects a large number of people.

According to the Cleveland Clinic in the United States, fear of the dark is most prevalent in children aged 6 to 12 years old.

The number of adults who fear the dark and experience anxiety in the dark is not insignificant. So, is adult apprehension of the darkness normal?

In the United States, nearly fifty percent of adults admitted to being afraid of the dark in a 2020 survey.

Normally, this fear is not a cause for concern, but when it interferes with daily life, it should be examined because it may be a sign of nyctophobia, a type of fear of night or darkness. People with nyctophobia are terrified of the dark and may experience symptoms including difficulty breathing, rapid heartbeat, chest tightness or discomfort, a shivering or tingling sensation, dizziness, and cold sweats.
It is also possible to develop nyctophobia if an individual does not sleep in the dark.

Then why do people fear the dark?
There are numerous causes for a person’s fear of the dark, such as experiencing darkness after watching a horror film.

According to a scientific study, this is also part of an evolutionary process.
People adopted a survival principle at the dawn of humanity, which stated that if darkness conceals dangerous animals, then one should avoid it.
People are generally not afraid of the dark; rather, they fear the unknown, disaster, or the unseen.

In other words, children or adults believe that there is a terrifying monster surrounding them in the dark and that the things they see are the result of abnormal brain activity.

According to experts, we lose our vision and cannot see anything in the dark. Humans rely heavily on their sense of sight for protection.

Consequently, in these situations, certain regions of the brain become extremely active to ensure safety, and some individuals experience fear during this process.
