How Much Water Do You
Really Need?

Water is a key nutrient—we can’t live without it. In fact, every system in the body depends on water. Our bodies use water to carry other nutrients and oxygen to cells, flush toxins out of vital organs, dissolve minerals, and keep mucous membranes moist. We constantly lose water so we need to replace it. But how much do you really need?

How Much Is Enough?

The amount of fluid you require depends on how active you are and how hot it is. Forget the typical rule of eight glasses of water a day— experts say some people may need much more. For instance, women ages 19 to 30 should try to drink at least 11 cups of fluid a day, while men in the same age group need about 16.

Strenuous exercise or exercise in the heat and humidity can tip the balance toward dehydration. Drink extra beforehand, plus ½ to 1 cup every 15 to 20 minutes. After exercise, drink at least two additional cups— more if it’s very hot.

Wet Your Appetite

Don’t drink water much? Here are some tips to help:
  • Keep a glass or water bottle on your desk at work.
  • Add a splash of fruit juice to plain or carbonated water.
  • Toss a bottle of water in your bag or briefcase so you can drink up when you’re on the go.

Dehydration can affect your memory, mood, and motor skills. It also may cause fatigue, headache, and dizziness.

QUICK TIP

Water is cheap, calorie-free, and low in sodium, but other foods and drinks count toward your daily hydration needs. For a nutritional boost, drink a glass of low- or nonfat milk. Brewed tea packs an antioxidant punch but watch out for caffeine. Fruits and many vegetables contain lots of water, too.
