Bacteria to Illness

[ThEmAdHaTtEr]

Alright, heres the story guys...I own 5 reptiles. One of the five stinks. That'd be the beardie. She's got a clean cage, but the cage just smells. So I've decided to change the substrate, and possibly build her another enclosure. I come to you to ask if theres anyway that the smell can make me ill? I've been sick since October basically, and now I have some type of stomach thing, where I'm constantly nausiated. So I thought, before I start building her another enclosure and such, could this be the cause of my illness? Thanks.
