RI Raise or lower humidity?

[Crazy4Herps]

Crazy4Herps have you actually seen low humidity cause RI. I have been looking and been unable to find any evidence anywhere for it. I would be grateful if you have reliable accounts . So far all I have found is rumours and my friends friends accounts My vet and published vets I have only found references to too high and low air flow, but never too low. I am very interested in finding out facts if you have references I'd love to see them!!!

I have. With my first ball python, I made the mistake of housing her in a glass tank (humidity here is around 20% during the winter, even with frequent misting the cage was ridiculously dry). I'd had her for a year or two, she had previously been in good health, and temps were all within range. The tank was just ridiculously dry. I recognized the RI, took her to our vet, and got her on antibiotics, but I had heard that drying out the cage helps with RI's, so I misted the cage even less. I'd keep her on antibiotics for the recommended time and she'd seem healthy, but the RI's kept coming back every 6 months or so. It wasn't until I read something (as you said, just a rumor) about low humidity causing RI's that I decided to raise the humidity to 60% (by that time I had the sense to move her to a tub), and she's been in good health ever since. I can't be sure without lung x rays, but I've been assuming that the RI's were a result of humidity being too low, and a stupid beginner's mistake turned into a chronic illness.
