I have a question about the chemistry of the shower fog that builds up in the stall during hot showers - if the water has gone through both water chlorination (with chlorine gas) and fluoridation (with either hexafluorosilicic acid or sodium fluoride (not sure which)), then do these chemicals enter into the body through the lungs while bathing? If yes, then would the amount taken in during a 5-10 minute shower be considerable? Comparable to the amount ingested when drinking a glass of water, for instance? I ask because I am responsible for the care of someone with a thyroid disorder, and it was recommended by their doctor that we keep fluoride consumption to a minimum. As for the chlorine, I was just curious. But does anyone know of any scientifically-documented incidences of exposure to these two chemicals via shower, and if no, would if make sense to assume so, based on the chemistry of what goes on in the shower (which I know little about). Would it make a difference if the chemical was either sodium fluoride or hexafluorosilicic acid, with one being a salt and the other being an acid?

Thank you for your time!

I think shower is no problem. It is better to check the food and drinks. There are more sources to get chemicals into the body. With a shower only a little bit if swalling the shower water. And the amount of flourid is low. In your region do they add flouride to the water?   Chlorine ok maybe is a problem. probably has to get an filter in the water pipe.

You're certain that there isn't any evidence to suggest that the fluoride compounds and dissolved chlorine don't condense when the fog is formed, or appear in greater concentrations in said fog? That's what I was paranoid about, and I thought that breathing in only a moderate amount of the fog while showering would result in greater exposure. I'm not sure if that makes any sense, though - it's what my friend told me. What do you think?

[Hunter2]

Flourid will not condensate, its dissolved as salt Chlorine can escape, but the amount should be also less. I think the water of a swimming pool contain more chlorine as tap water.

Does hexafluorosilicic acid behave in a way similar to the fluoride salt, in the sense that it also cannot escape through condensation?

[Hunter2]

Yes it  is similar.
