What is it Heliophobia?

Heliophobia is the irrational and abnormal fear of the sun, sunlight or any bright light. It is a type of specific phobia.

Fear of open spaces is often an associated fear. Sufferers will keep shutters and blinds closed and curtains drawn to keep sunlight out. Phobics also tend to be “night owls” and be more active at night.

The Pacific Health Center has suggested that many people avoid the sun because of growing fears about skin cancer. This behavior, however, is not technically heliophobia.

Heliophobia is also closely related to and sometimes considered the same as phengophobia (fear of daylight, sunlight or sunshine) and eosophobia (fear of dawn or daylight).

The name originates from the Greek word “helio” meaning “sun".

Causes of Heliophobia

A medical condition can underlie heliophobia in the sense that sensitivity to bright light can be painful or uncomfortable.

Heliophobia is a specific (or “isolated”) phobia, centered on non-social key factors. Isolated phobias tend to have some previous trauma (often in childhood and often physically injurious) as a root cause; a fear of bees may stem from an injury in childhood, for instance.

Upbringing can also play a role, such as parental warnings about a direct threat (such as “snakes can bite and kill you”) which is especially notable in cases where a threat is more imminent. (An allergy to bees or peanut butter, for instance, would naturally reinforce a real medical concern.)

It is thought that genetics and hereditary factors may play a role in specific phobias, especially those related to a danger of injury. (A primal “fight or flight” reflex may be more easily triggered in those with a genetic predisposition, for instance.)

By contrast, social phobias (like a fear of body odor or touch) are less well understood, are driven by social anxiety and are broadly labeled as “social anxiety disorder”.

In all kinds of phobias, external experiences and / or reports can further reinforce or develop the fear, such as seeing a family member or friend who is affected. In extreme cases, indirect exposures can be as remote as overhearing a reference in conversation or seeing something on the news or on TV and movies.

Heliophobia, like most phobias, stems from a subconscious overprotection mechanism, and as with many phobias can also be rooted in an unresolved emotional conflict.
