H2O Question?(6 posts)

H2O Question?garhead
May 28, 2002 2:25 PM
Since I'm new to the bike scene & was hoping someone can explain this. I was doing a century(Santa Fe) & I normally like to mix my water & GatorAid somewhere around 50/50. For some reason at one of the rest stops toward the end(of course) I only filled up with water, no mix. I thought I was doing to die as my mouth became incredibly dry. What was happening?????
TIA

I also mix water and Gatoraid 50/50. I think that the dry mouth was due to the dry air evaporating your saliva. The mixture had glucose in it that caused your mouth to release move saliva which kept your mouth feeling damp. Just my opinion of course.

That'd be my guess, tooretro

This is pure speculation, but I'm inclined to agree. The air's generally dry in Santa Fe, and assuming you were breathing through your mouth sometimes (I would have been), it could have dried out. GatorAde sometimes makes me sick to my stomach, so toward the end of a long ride I dilute it 3 to 1 or more with water. I've noticed a similar dry mouth thing, but I just figured it was because I was dehydrated and tired.

I also use gatoraid, but one bottle with GA and the other with plain water. I then take 1 sip GA and my next drink is h20, all throughout the race. then, for some reason I finish the GA first. afterwards I just use h20 and I never had a dry mouth. where I live summer temps. reach an excess of 120F. of course I don't ride when its that hot, but my summer morning rides usually end when its reaching the 100's.
you might want to try 1 full bottle of Ga and 1 full bottle of h20. until now it has never made me sick.

Dry mouth is often due to sympathetic nervous stimulation (part of the autonomics) Maybe you got a big shot of adrenalin released for some reason?

As a somewhat related aside, anyone ever notice a drop in heart rate after taking a big slug of cold water? I sometimes notice a drop of up to 20-25 bpm. I'm guessing this is due to parasympathetic vagal stimulation. Apparently the vagus N. is close enough to the esophagus that the cold water "zings" it.
