Low blood pressure, congestive heart failure and blood vessel disease involving the kidney can make matters worse. Taking diuretic medications also adds to the challenge. Therefore, older adults need to be especially careful to make sure they get adequate fluids. Most adults should try to drink eight 8-ounce glasses every day. Your morning coffee or tea probably has caffeine, which acts as a diuretic, as does alcohol.
Healthiest choices are plain water, seltzer water, milk and pure fruit juice.
Try adding some lemon slices to your water to give it a little twist. Take water breaks instead of coffee breaks. Don't pass a water fountain without stopping for a drink. Carry a bottle of water when traveling.
