Not on its own. You’d have much more of a risk of shorting out because the water condenses on all the surfaces.

Pure water is a fairly poor conductor, and the ions that make it conductive don’t always follow the water into the air.

You can force it to be conductive by using a high voltage current, but a high enough current will make anything conductive, given enough power, so that’s probably despite the point.

Short of super-saturating the air, it’s probably difficult, if not impossible to make it inhospitable to breathe in with eager vapour. Water can only hold so much, and while you can increase the amount it can hold by changing the temperature, you’d be overheating the the traditional way at that point.

Maybe some extreme super-saturation of the air, so the water condenses in the airways? Although that’s extremely unlikely, since it’ll probably condense on the rest of the person, and the available surfaces first.
