Have you felt more dehydrated after drinking bottled water?

Answer 1

Yes.
A number of possibilities exist in this case, and some people may know more than I do.
1. According to popular health gurus, your body needs at least half of your body weight in ounces each day. For example, if you weigh 200 lbs., then you should drink 100 oz. of water per day. Now, when you start drinking water, which your body naturally craves, you may become thirsty very soon after you drink water, whether that water is bottled or not. Your body is telling you that it needs more of what you just had. In this case, bottled water may have nothing to do with why you feel dehydrated; your body is simply telling you that it needs more water.
2. A lot of the popular bottled waters, such as vitamin water, are really full of bull and are better left alone. Chemical vitamins do little to nothing for your health. My advice is to drink straight spring water from glass bottles if possible. Non- purified spring water should contain quite a few trace minerals that are incredibly beneficial to our health. This is water as nature intended. So, if you are referring to adulterated water (water with additives) when you say "bottled" water, then these chemicals may make you thirsty because your body craves straight, earthy, natural water.
3. If you are accustomed to drinking tap water, which in nearly all US municipalities contains chlorine, then suddenly switch to water that is chlorine-free, you will find your body craving more of the "natural" bottled water that you just drank. It is your body's way of telling you, "Hey! I'm finally getting what I need; give me more!" I am not an extremist, but I am educated on chlorine. America is a great country, but we are killing ourselves incredibly quickly. Chlorine is deadly, and in minute amounts over a long period of time, it promotes daily dehydration, irritable bowel syndrome, and is an accomplice in a host of other digestive problems. And when you have digestive problems, it affects your entire body. Even a hot shower is detrimental to your health over time. Chlorine evaporates at a lower temperature than water, so when you take a hot shower, you inhale more chlorine than you usually drink throughout the day. My advice is to get a filter for your sink and shower that removes chlorine.
4. Check on water acidity or alkalinity using an internet search engine. This may provide some more answers. There is a doctor in Greenville, SC, Dr. Awe, who has helped me hydrate myself better. Supposedly, my body utilizes over 90% of the water that I drink as opposed to my previous 50-60%. If your bottled water is acidic, then you may not be getting much hydration from it. I'm not an expert on this part of the water subject, so try some more of your own research.
Good drinking! No coke!
