As a general rule, you should take one-third of your body weight and drink that number of ounces in fluids. For example, if you weigh 150 pounds, aim to drink 50 ounces of water each day.
How to prevent dehydration in older adults? 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.
You should aim for 6 to 8 glasses of fluid a day.
We need it to keep our organs and body healthy, help us digest food, absorb nutrients, and get rid of waste. According to the Reynolds Institute on Aging, Seniors should aim for 6 to 8 glasses of fluid a day, or approximately 1.5 liters.
The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for women.
Daily fluid intake
The Eatwell Guide recommends that people should aim to drink 6 to 8 cups or glasses of fluid a day. Water, lower-fat milk and sugar-free drinks, including tea and coffee, all count.
The recommended daily water intake is at least one cup of water for every 20 pounds of weight. If living in a warm climate, seniors might perspire and need more water. Exercise also increases the need for water as does medications and health conditions.
Here is one more reason to enjoy that morning cup of joe: “Coffee counts toward your daily water intake,” says Lauren DeWolf, MS, RD, a registered dietitian with Sharp Rees-Stealy Medical Centers. The water in coffee, tea and other caffeinated beverages helps us meet our daily fluid needs.
How much should I drink a day? A healthy adult needs around 35 ml of water each day per kilogram of body weight . At least according to the general guidelines from scientific organisations.
To meet your fluid needs throughout the day, choose water most often. Remember that other fluids like milk, coffee, tea and juice also count towards your daily fluid intake.
How Much? Under the usual conditions of life, 3 – 4 liters of fluids a day will provide 2.5 to 3 liters of urine volume, and this is enough. The average healthy adult bladder holds about 1/2 liter, so this means 7 – 9 bathroom trips in 24 hours.
Why are older adults more susceptible to dehydration? Older adults are at a greater risk for dehydration because of how body composition changes with age. Those in the 65-and-older crowd simply have less water in their bodies than younger adults or children.
Alleviates constipation and diarrhea. May decrease the risk of certain cancers, such as bladder and colorectal cancers. May decrease the risk of kidney stones. May improve overall skin health.
To avoid hyponatremia, it is important not to outpace the kidneys by drinking more water than they can eliminate. The authors of the study report that hyponatremia symptoms can develop if a person drinks 3–4 liters of water in a short period, though they do not give a specific time estimate.
People who don't drink enough water every day are at greater risk of kidney stones, problems with their heart valves and some kinds of cancer. Even minor dehydration can affect physical and mental performance. Drinking water is also essential for the health of your mouth.
Hydration is vital because it keeps electrolytes balanced, blood volume normal, aids in digestion, transportation of nutrients, and kidney functioning. And if your elderly loved one becomes dehydrated, they have the added risk of mental confusion.
“Decreased body water content is the most common factor that increases serum sodium, which is why the results suggest that staying well hydrated may slow down the aging process and prevent or delay chronic disease.”
As you grow older, health problems or prescribed medicines may require that you drink less alcohol or avoid it completely. You may also notice that your body's reaction to alcohol is different than before. Some older people feel the effects of alcohol more strongly without increasing the amount they drink.
