Heliophobia is a fear of the sun

Heliophobia is the irrational fear of light, specifically sunlight.  The word “helio-” comes from Greek, meaning “sun”, and “-phobia” means fear. As such, heliophobia is defined as an irrational phobia or dread of the sun.

Heliophobia is a largely irrational fear. The sun provides life to all on Earth. However, we all understand that the sun is super bright and powerful. Since the sun is so powerful, perhaps a fear of heliophobia comes from being burned by its heat or blinded by its light.

Heliophobia, on the surface, may seem irrational fear, but in reality, it’s much more complex than that. Heliophobia is not just about a simple phobia of light or heat, although some people who have heliophobia do report feelings of intense discomfort when exposed to either one individually.
