Dry mouth on a FF?

[Jefe]

I am using my Quattro, and for a week before that a F&P 432. Even with the humidifier on almost full blast, I wake up with a bone dry mouth! The humidifier is on, and the tank level is going down, so I know it's working.

Why am I waking up so dry?

I am using an F&P 432 and wake up with a dry mouth from time to time as well. My humidifier is about half way up and the water level goes down during the night. I notice it most when I have been asleep for a good long time (2 -3 hours) at a stretch. I attribute it to the fact that during these extended periods I am mouth breathing -- which is why I use a full face mask in the first place -- and the increased airflow is drying out my mouth.

I think the humidifiers are designed to generate enough humidity to keep the nasal passages from drying out, but may be a bit undersized to generate enough humidity to keep the much larger surface areas of inside the mouth from drying out. I could try turning my humidifier up some and see if the problem goes away. I am sure -- especially given the posts over the last few days -- that someone will correct me if my theory is wrong.

Since your humidifier is turned all the way up, I am not sure what to suggest for a solution. Maybe a hose cover to keep the air in the hose as warm/moist as possible.

I have a Quattro and before that a UMFF. I found that nights I have woken up with a really dry mouth are the ones showing more or larger leaks. Could that be an issue for you? I also turned my humidifier up to 3 from 2.

I have heard that using Biotene mouth wash helps, as it is supposed to keep your saliva production going. I do think mouth breathing, even in a FF will make your mouth drier...

Jefe, sounds like you are mouth breathing, I know when I used the full face mask I would still mouth breath, and have a dry mouth no matter how much humidity I would increase to, I finally overcame the mouth breathing, just by training the tongue to set behind my upper teeth, a full face mask is a better mask for treatment of mouth breathers, but you will still get dry mouth unless you correct that problem, keep working at it you will eventually get it.
Good sleep and peace to you.

Jefe,

There is a larger HH that can be purchased and attached to your machine if I recall correctly. I read it in another post. If the problem persists after you've tried the other solutions and you need a larger humidifier try do a search or post looking for larger humidifiers...I'm sure someone can give you the info!

Good luck!

I think you guys are going the wrong way with your humidity. Turn it down or off ("passover" mode). It's been discussed a number of times previously that more warm humid air can have the effect of closing off the nasal passages.....which causes you to mouth-breathe.....which causes dry mouth. Cooler air makes it easier to breathe through your nose.
