How Much Water Do You Need to Drink?
How Much Water Do You Need to Drink?

At least twenty percent of the water you need comes from the foods you eat. The rest comes from the beverages you drink. Some experts believe you can estimate the amount of water you need by taking your weight in pounds and dividing that number in half. That gives you the number of ounces you may want to drink each day. For example, if you weigh 160 pounds, you might want to drink at least 80 ounces of water or other fluids per day. Other factors include amount of physical activity and the climate where you are located. My hydration calculator can help you determine how much water you need to drink each day.

Water is probably the best choice for rehydration because it's cheap and has no calories or added ingredients. Tap and bottled are often fluoridated, to help prevent tooth decay. Sweetened soft drinks and sodas have added sugar that adds extra calories but no additional nutritional value. Sports drinks contain minerals that may help keep your electrolytes in balance, which is good for recovering after a hard work out, but look out for added sugar and calories that you may not want. Fruit and vegetable juices can be a good choice because they have vitamins and minerals your body needs (read labels, however -- vegetable juices may be high in sodium). Caffeinated beverages like tea and coffee count too, but too much caffeine can make you feel jittery.
