I've recently started cycling and running. I've been getting a dry throat and sometimes a bloody nose from the heavy breathing while doing these activities. I live in Arizona, and it's really hot and dry, so I think it might be the cause. The only thing I've found to help so far has been chewing gum while cycling, and sometimes that doesn't even help. Also, that's not really an option for me while I run, since the breathing is more labored and I don't wanna choke. Does anyone have any tips on how to avoid this?
