Our bodies constantly lose water mainly through sweating and urination. As the body is around 60 percent water more or less, there are varying opinions on how much water has to be taken in per day. It is generally accepted that water helps you stay slim and regular. Getting enough water keeps the metabolic rate at peak efficiency and also the digestive system working optimally.
Despite the general consensus that we should drink eight 8-ounce glasses of water each day, the quantity of water we actually take in is more individualized than we may think. Amidst that, knowing how much water one should drink is not a cut-and-dried concept. This becomes even more complicated if you consider what some health gurus are saying that we need to constantly sip water throughout the day regardless if we are thirsty or not.
The fact of the matter is, water consumption depends pretty much on the individual and that is aside from the variety of internal and external factors that have an ultimate influence on our water needs.
The 8-glasses rule is a good starting point but it is not a concept based on solid, deeply-researched information. The recommended intake is dependent on a variety of factors such as age, sex, activity level, among others. Breastfeeding and pregnant women are just some of those that exhibit variability in the recommended intake.
It is currently recommended by the Institute of Medicine (IOM) that people ages 19 and older drink around 72 ounces or about 9 cups or 2.7 liters of water for women while men should drink at least 104 ounces or around 13 cups or 3.7 liters of water. This denotes the overall fluid intake per day and includes any water-containing food or drink such as vegetables and fruit.
The recommended water intake for children has much to do with age. For boys and girls between 4 and 8 years, around 5 cups or 40 ounces per day is recommended. By ages 9 to 13, this becomes 7 to 8 cups or about 56 to 64 ounces. Youngsters from 14 to 18 should take in 64 to 88 ounces or around 8 to 11 cups.
The recommended water intake for breastfeeding and pregnant women changes as well. Regardless of age, pregnant women should take in ten 8-ounce glasses of water each day, which is around 80 ounces. The total water intake for breastfeeding women can go as high as 13 cups or 104 ounces.
For those who are trying to lose weight and who are already well hydrated and having plenty of water intake, drinking more water is not likely to make plenty of difference. However, for those who go through every day with very little water or are hugely dehydrated ought to get enough water to see palpable success in their weight loss programs.
