Allergic to sunshine???
« on: 25/06/2003 12:07:40 »
Whenever I step outside into bright light I sneeze. Is there a reason for this? Am I just weird?

Or is it just a series of coincidences and I'm being silly?

Am I dead? Am I alive? I'm both!

Quantum, it's just you being silly. Only joking really;). I really don't know about this but I saw news about a kid whose skin is allergic to sunlight and too much sunlight could kill her. She has to measure the amount of sunlight before she goes out and even when she's out she has to wear long, thick clothes to cover her skin.

I agree - the same thing happens to me from time to time. Strong sunlight provokes an intense sensation of wanting to sneeze.

This must be the consequence of some cross-wiring in the nervous system which produces this reflex. I'll have to look into it.

Sometimes I sneeze too but not always. I've never noticed this until you mention it Quantum.

you lack the pigments from your skin which resist the skin from sunlight consult your doctor for some sun blocks.You can also use sunglasses and a cap for that.

I would suggest your eyes are nothing to do with the skin pigment, I wouldn't fancy rubbing factor 15 into my eyes... i don't think that is the answer. It would be interesting to know exactly why we respond to bright sunlight by sneezing and why it affects some people more than others. I agree however that sunglasses help to stop it.

Itchy fingers - that's an unusual one - could be because your friend has touched something which is a photosensitising agent and then gone out in the sunlight...there are certain plants that produce substances including psoralen which make the skin more sensitive to UV than normal.

It's not because of skin pigments because I usually try to close my eyes when I know I'll be walking into bright sunlight, and when I do I don't sneeze.

When I was a child and had a "nose-tickle" and needed to sneeze my mother would tell me to "look to tha' sunshine darlin".  It always worked and I tell my children the same thing. There must be some connection -- just like its impossible to keep your eyes open when you sneeze. Some of those old wives tales actually work....I have learned that some are actually tried and true old remedies handed down from mother to daughter over generations.

I do find that looking into the sunshine when you already have to sneeze wilol make it happen, however, looking into an electric light has the same effect.  I think in that case, it's not the sunshine but just light in general.

No, it's not an allergy at all - no histamine reaction reported.

The most common explanation is "crossed wires" in the brain - the optic nerve stimulating the trigeminal nerve and thus triggering a sneeze.
There's a fuller explanation on newbielink:http://www.photic-sneezing.fr.st/ [nonactive].  

As for sunglasses helping, opinion is divided. The only scientific paper on the subject suggested it did not, but as only one person was examined, this may be purely individual.  I find sunglasses do help to a certain extent but if the sun hits my eye from a certain angle, sunglasses or not, it trips off the sneeze reflex.

Yep ... it's really annoying. As long as the light isn't too sudden, I don't sneeze. Do you find the same thing? I try to move to a brightly lit area slowly, perhaps to a half-lit room first to prevent it.
