Sun allergies, also known as photodermatitis, can cause a variety of symptoms, but sneezing is not typically one of them. Sun allergies are an immune reaction to ultraviolet (UV) radiation from the sun. The most common symptoms of sun allergies include itching, redness, and rash.
However, sneezing can be caused by a different phenomenon related to sunlight known as photic sneeze reflex, also known as ACHOO syndrome. This is a genetic condition that triggers uncontrollable sneezing in response to bright lights, including sunlight.
It's important to note that while sun allergies and photic sneeze reflex are both triggered by sunlight, they are distinct conditions with different causes and symptoms.
To summarize:
- Sun allergies: Primarily cause itching, redness, and rash, not sneezing.
- Photic sneeze reflex: Triggers sneezing in response to bright light.
