Carbonated water can count towards a person's daily water intake as long as there are no added ingredients such as sodium or caffeine, which may lead to dehydration.
More Info: Carbonated water is a hydrating and refreshing variety of water that simply has carbon dioxide gas added to it for a carbonated effect. Many people, who do not otherwise enjoy drinking water, prefer carbonated water for its consistency and the feeling of satiety that it brings. The carbon gases found in carbonated water may cause some people to feel fuller after consuming it.
Fact: When considering purchasing bottled water, carbonated water has fewer bacteria than other waters due to the acidity created by the carbonation.
Fact: While adequate water intake varies from person to person, the general recommended daily intake of water is around eight 8-ounce glasses of water each day. In general, approximately one quart of water is needed for every fifty pounds of body weight.
Fact: Perspiration, respiration, urination, and defecation are all natural means of water depletion throughout the day. Other means include excess caffeine and sodium. Enough fluids should be consumed so that thirst is rarely present. Once thirst is noticed, the body is already entering into a state of dehydration.
Fact: The larger you are, the more water you will need to consume throughout the day to remain hydrated. Additionally, men should take in more fluids than women. If you live in a dry climate, your water intake should be higher than someone living in a moderate climate.
Fact: The color of your urine is an indication of your level of hydration. Urine that is pale yellow, resembling lemonade, is an indication of sufficient body hydration. Darker color urine, similar to apple juice, indicates that you need to consume more fluid.
