Cleaners and chemicals really can be deadly for asthmatics, and even if something didn't effect you're lungs once that doesn't mean it wont the next time you smell it ......I've got a huge list of sense I can't be in thw same hosue with , on the topm of the list would be my old time favorite perfume SUNG , I wore it for years and then it just progressively started bothering me untile the point where it started to give me instant attacks. Bleach is a biggy to and these little very intense Glad air freshener all have our triggers you're pocket ), both make me end up in the hospital everytime I get a whiff of them. We all have different triggers and they can change from day to day ..so be aware and be carefull and well all live longer
