Southwest Indians & Respiratory Infections (Europeans, USA, Phoenix)

[Juxtaposition109]

I have a history/health question. I heard someone say that many Indians such as the Apache who were native to the SW USA developed respiratory problems when they were forced to move to the SE USA due to the SE's humidity and they were raised in a dry climate w/o a lot of humidity. I tried researching it via Google etc but I haven't found any good information about it. I know many Indians died out of diseases that they didn't have immunity to when they were exposed to Europeans but this sounds like more of a climate issue. Do any of you have any good information on this? If someone in our modern times grew up in the SW USA say in a place like Phoenix but then moved to the SE USA where there was a lot of humidity would they likely end up w/ respiratory problems? Have a good one my fellow city data peeps.
