How Much Water Do I Need? General recommendations The National Academy of Medicine suggests an adequate intake of daily fluids of about 13 cups and 9 cups for healthy men and women, respectively, with 1 cup equaling 8 ounces.

Lower amounts may be needed for those with smaller body sizes. Fever, exercise, exposure to extreme temperature climates very hot or cold , and excessive loss of body fluids such as with vomiting or diarrhea will increase fluid needs.

The amount and color of urine can provide a rough estimate of adequate hydration. Generally the color of urine darkens the more concentrated it is meaning that it contains less water. However, foods, medications, and vitamin supplements can also change urine color. Alcohol can suppress anti-diuretic hormone, a fluid-regulating hormone that signals the kidneys to reduce urination and reabsorb water back into the body.

Without it, the body flushes out water more easily. Enjoying more than a couple of drinks within a short time can increase the risk of dehydration, especially if taken on an empty stomach.

To prevent this, take alcohol with food and sips of water. Although caffeine has long been thought to have a diuretic effect, potentially leading to dehydration, research does not fully support this.

The data suggest that more than mg of caffeine daily about two cups of brewed coffee may increase urination in the short-term in some people, but will not necessarily lead to dehydration.

Therefore, caffeinated beverages including coffee and tea can contribute to total daily water intake. Aside from including water-rich foods, the following chart is a guide for daily water intake based on age group from the National Academy of Medicine: Age Daily Adequate Intake years 4 cups, or 32 ounces years 5 cups, or 40 ounces years cups, or ounces years cups, or ounces men, 19 and older 13 cups, or ounces women, 19 and older 9 cups, or 72 ounces pregnant women 10 cups, or 80 ounces breastfeeding women 13 cups, or ounces Preventing Dehydration: Is Thirst Enough?

Are seltzers and other fizzy waters safe and healthy to drink? Water becomes bubbly through the process of carbonation and is sometimes suggested as a healthier alternative to soda. Carbonation involves dissolving carbon dioxide gas in water under high pressure; when the pressure is released, bubbles form.

This process lowers the pH of water from 7 to 4, which is more acidic. The acid level has raised concerns that seltzer and soda water may harm dental enamel or bone health.

However, research has not shown that carbonated beverages are associated with dental decay unless they also contain sugar or other sweeteners like high fructose corn syrup. Furthermore, studies have not found that carbonated beverages are associated with decreased bone mineral density; the culprit is more likely the high phosphorus content specific to dark cola soft drinks than the carbonation.
