    I don't know, but it can be annoying at night. I end up waking up several times during the night to use the toilet due to all the water I've drunk.

    I believe the vapor is produced by extraction of water from inside our mouth and nasal passages. Love that vapor - hate drinking so much water...........

    To avoid the dehydration I added 'some' water, not a lot, and switched from regular coffee to mostly decaffeinated. I still have two cups of regular to start the day. I haven't noticed much in the way of problems with dehydration since my early days.

    Tip: When brewing decaf, add an extra scoop of grinds grounds...

    I could give you the chemical reasons but I think you want a simple answer... Think about all the vaper that you breathe out, that is all water coming from your body...that is what you are replacing and no it does not have to be water, any fluid will do, so long as you replace what you are taking from your body. lol Just thought alcohol is fluid but that also dehydrates, so would not be a total replacement :D

    This is it. It took me a while to get used to drinking so much anything used to just be coffee. Now I am always sipping on a bottle of Smartwater. I just keep it handy I don't chug alot I just sip after about ten pulls or so but if you notice that your juice lost it's flavor you are beginnring to get dehydrated. So drink up and Vape Away!

    No expert, but anything like that should hydrate you. Fruit Juice, Tea and even Fizzy Juice (Pop) apparently.

    Any liquid will do.... I use flavored water and tea mainly. I drink about 4 bottles extra a day.

    I'll take the Chemical Reasons.

    Gatorade is great and it soothes your throat.

    Me too, I've never understood this explanation. How exactly does your mouth create this much water vapor in such a short time?

    I am not a chemist but both PG and VG are diuretics. All diuretics increase the excretion of water from bodies, although each class does so in a distinct way.

    PG and VG are Humectants.

    Humectants are additives that bind water and help to retain moisture. Although humectants have applications in many industries - pharmaceutical, cosmetic, veterinary - they are commonly used in foods. Water activity reduction achieved by adding humectants to food enhances stability, maintains texture, and reduces microbial activity.

    Humectant use in foods is widespread and has a long history. Salt and sugar are the oldest, most widely used humectants. Other commonly used humectants include sorbitol, glycerol, and propylene glycol.

    PG and VG absorb some water when vaped, but the main vapour is produced from the liquid, not from the tiny amount of moisture absorbed from your body. If you attach an ecig to a suction pump, similar to that used in trials for the Clearstream Protocol, vapour is produced without any contact with the body or other moisture-holding materials.

    So yes, vaping will dehydrate you to some extent, proportional to the amount you vape.


    No chemistry books were harmed in the making of this post ;-)

    Edit: Glycerol was formerly classified as a diuretic, but it is now accepted that there is little extra urine flow at doses between 1.0 to 1.5 g/kg. In September 1997, the US Olympic Committee removed the ban on glycerol.

    Thanks for that John, very informative. And it confirms my suspicions that the main bulk of the vapour came from the liquid, I mean after all thats what a PV does....vapourises liquid :)
