The answer is “yes”. In a way, e-cigarettes may cause dehydration. Many who are new to vaping would have come across the symptoms of “cotton mouth” (dryness of the mouth) and this is mainly due to the fact that they do not drink enough water.
Drinking a lot of water is important whilst vaping
How much water should we drink a day? As medical experts advise, we should be drinking 12 cups of water a day, or 2 liters to replace lost fluids in the body. But again this is just an estimation according to the professionals, as it really depends on the size of your body and if you’re physically active or not. If you are, you lose even more water thus you have to drink more to replace the fluids.
Even if you are not yet a convert and you’re still a smoker, I’m sure you you would have noticed the feeling of dehydration when you smoke too many cigarettes a day. Whatever chemicals and toxins that are in tobacco cigarettes do dry out the body, and quite extensively. This is probably part of the reason why most heavy smokers develop wrinkles and have dry skin early on.
If you are vaping e-liquids all day like I am, you will need to drink even more fluids. Let’s see why…
The effects of Propylene Glycol
PG, along with other substances like sugar, honey, salt and glycerol are hygroscopic substances, meaning that they attract and hold moisture. When you vape a lot with your electronic cigarettes, the PG in the juice basically traps some of the moisture in your mouth and body and dehydrates you. You can read more about propylene glycol and its effects here.
Increasing VG to reduce dehydration
Now there’s no medical evidence of this but from what I’ve read on the forums, many users advise that vegetable glycerine (VG) can help with these symptoms. If you’re having problems with dehydration, you can increase your PG/VG to a 60:40 ratio. I personally like to vape 80:20 e-liquids and although I do get that dry mouth feeling, I don’t suffer from dehydration because I drink as soon as I feel thirsty. With a higher PG ratio, you get better flavor out of your e-liquids as well as a better throat hit, and that is how I like it.
Note: I am not a medical expert though and I’m just telling you about my experience in general. When something concerns your health, you should always seek the advice of your medical professional – always.
Symptoms of dehydration
I’ve already covered this in a previous post but to reiterate, these are the symptoms you will notice when you vape too much and get dehydrated:
• muscle cramps
• dry mouth
Your body requires enough fluid to carry out normal functions such as the removal of toxins from your vital organs and also to carry nutrients to cells. Your lungs, ears and throat need moisture to be in a healthy state as well. Moisture is so important to your body that even a case of mild dehydration can leave you feeling lethargic.
I’ve also written a post recently about losing my taste buds with flavored e-liquids, which you should read. I think it was mainly to do with mild dehydration or something. I wasn’t really that dehydrated to be honest but everything I vaped just tasted bland. This was easily resolved by drinking some green tea, and other sweet drinks like soda.
Watch out for diuretics
Remember too if you drink a lot of coffee or other diuretics, you will need to drink even more water to keep your body well-hydrated.
