Experts generally recommend that older adults consume at least 1.7 liters of fluid per 24 hours. This corresponds to 57.5 fluid ounces, or 7.1 cups. What are the best fluids to prevent dehydration? I was unable to find research or guidelines clarifying which fluids are best to drink.
The recommended minimum total fluid intake is 1500–2000 mL, (equivalent to 6–8 250 mL cups) a day. This comes from all sources including soups and beverages.
When you drink too much water, your kidneys can’t get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.
For calculating the minimum amount of fluid per day, a formula based on body weight is recommended: 1500 ml is the minimum water intake with 15ml fluid per kg to be added for the actual weight minus 20 kg. This formula can be used for older adults who are normal weight, underweight, or overweight.
Here’s Why. Researchers say that as people age, they need to drink more water to compensate for changes in their body temperature regulation. They say dehydration can cause a number of ailments, including muscle pain, fatigue, and heat exhaustion.

Health experts commonly recommend eight 8-ounce glasses, which equals about 2 liters, or half a gallon a day. This is called the 8×8 rule and is very easy to remember. However, some experts believe that you need to sip on water constantly throughout the day, even when you’re not thirsty.

For most people, there is really no limit for daily water intake and a gallon a day is not harmful. But for those who have congestive heart failure or end stage kidney disease, sometimes water needs to be restricted because the body can’t process it correctly.
Hydration in the elderly can be easily managed with these simple tips:
Skin turgor (elasticity) has been mentioned by few studies, but most report its limitations when assessing hydration status in the elderly. The turgor is usually assessed by pulling the skin and observing how long it takes to return to the baseline state; with values longer than 2 seconds associated with dehydration.
Signs of dehydration include:
Juices and sports drinks are also hydrating — you can lower the sugar content by diluting them with water. Coffee and tea also count in your tally. Many used to believe that they were dehydrating, but that myth has been debunked. The diuretic effect does not offset hydration.
Your general water requirements can be determined using your current body weight. Most people need to drink roughly half to two-thirds of their weight (in pounds) in ounces. For example, a 200-pound adult needs approximately 150 ounces of water each day.
Below are some of the most common causes of dehydration in older adults:
