Water, Water Everywhere… Tufts

Hydration is essential for health, especially with outdoor temperatures high. Since water is necessary to deliver nutrients and oxygen to cells, aid digestion, control blood pressure, and regulate body temperature, getting enough fluids every day is essential to helping the body function properly.

Hydrate! While all kinds of beverages and many foods provide us with fluids, water is the best drink to keep us hydrated. There is no recommended daily intake level for water, as needs vary with many factors, including ambient temperature, activity level, and types of foods in the diet. Be aware that older adults are at an increased risk for dehydration because they may not sense the need for fluids in response to their bodies’ hydration state as well as they did when they were younger.

The commonly stated goal of drinking eight
(eight-ounce) cups of water a day has no firm scientific basis, but it is generally considered a reasonable goal. One way to tell if you’re getting enough fluid is to pay attention to your urine: dark urine indicates inadequate hydration.

Water Choices: Bottled waters are now the number one beverage in the U.S. These products come at a cost—both financial and environmental—so knowing what you’re getting and weighing your options carefully is important.

Tap water from public water systems is regulated by the Environmental Protection Agency (EPA). Routine testing of public water is required, and test results must be made available to the public. If your water comes from a well, the Centers for Disease Control and Prevention recommends having it tested once a year. Although U.S. drinking water is among the safest and most reliable in the world, it is not without controversy. Many people choose to use a whole house, under-sink, refrigerator, or pitcher-based filter system at home.
