How Much Water Do You Really Need to Drink?

Water intake regulates body temperature, transports nutrients and oxygen and carries away waste – but lots of us don’t get enough. Here’s how to ensure you stay hydrated:

Normal water needs

First off, needing to drink 8 tall glasses of water a day is a myth. What you really need is enough fluid to replace what you lose each day in your sweat, urine, breath, and other bodily excretions. That’s about 8 to 10 cups of water. Because we get about 4 cups’ worth from fruits, vegetables, and other foods, that leaves 4 to 6 cups for you to make up with beverages.

How to tell if you’re getting enough water

The typical person urinates 4 to 8 times a day, but that varies based on each person’s unique anatomy. More telling is the color and smell of your urine; assuming you’ve had a normal diet, your urine should be pale yellow and without a strong odor.  If it’s dark yellow or smells like ammonia, you probably need to drink more water. Urine can have other colors based on what you eat, so if occasionally your tint is unusual, don’t panic. Its likely will return to normal the next time you visit the loo in a few hours.

 How much water to drink for weight loss

Water can help rev your metabolism when you’re trying to lose weight. To help, put five rubber bands around your wrist every morning. That’s how many 16-ounce bottles of water you should drink during the day to rev up your metabolism, helping to burn more calories. Researchers estimate that over a year, increasing your water consumption by 1.5 liters a day would burn an extra 17,400 calories, or about 5 pounds (2.25 kilograms) worth. And because much of the increased metabolic rate is due to the body’s efforts to heat the liquid, make sure the water you’re drinking is icy cold.

How much water to drink during exercise

Of course, you may need more water in hot weather or if you’re exercising or being more physically active than usual. So if you’re still thirsty, sip more. About two hours before exercising, drink two to three cups of water. This will help ensure that you won’t be dehydrated during your workout. Then, have on hand enough water to drink about a cup every 15 minutes of exercise. Afterwards, sip another two or three cups.
