Can you be al­ler­gic to smells?

iD magazine - - Questions& Answers -

Even where the most se­vere al­ler­gies are con­cerned, the mere smell of the of­fend­ing sub­stance alone can­not trig­ger an al­ler­gic re­ac­tion. The pro­teins re­spon­si­ble for the body’s re­sponse are not trans­mit­ted by the aroma. For ex­am­ple, al­lergy suf­fer­ers are able to smell peanut but­ter with­out hav­ing to worry about hives or breath­ing dif­fi­cul­ties. It’s only when cer­tain foods are cooked that a large quan­tity of the pro­tein par­ti­cles from the food be­come re­leased into the air, and in­hal­ing th­ese mol­e­cules could re­sult in an al­ler­gic re­ac­tion.
