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.
How much fluid should I drink? Drink plenty of fluids – water is best. As a guide, you should not feel thirsty and your urine should not be a darker yellow than usual. Adult women need about 8 cups (around 2L) and adult men need about 10 cups (around 2.5L) of fluid a day.
“In general, you should try to drink between half an ounce and an ounce of water for each pound you weigh, every day.” For example, if you weigh 150 pounds, that would be 75 to 150 ounces of water a day.
Drinking at least 64 ounces (eight cups) of water every day may help with weight loss. Downing liquid is not the only way to meet this goal. About 20 percent of your hydration needs can be met through your diet, says Caroline Susie, RDN, a national spokesperson for the Academy of Nutrition and Dietetics.
Water is the key to life, and it turns out it's also one of the easiest ways to help your metabolism. Drinking water increases your metabolism by up to 25% for nearly an hour after drinking it. That means if you drink a few cups of water every hour, you'll keep your metabolism at peak performance all day.
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. A person weighing 50 kilograms requires 1.7 litres, 60 kilograms 2.1 litres, 70 kilograms 2.4 litres and 80 kilograms 2.8 litres.

Mineral, structured, and pure spring water are some of the healthiest water you can drink because they're clean and contain all the essential minerals your body needs. Filtered water removes contaminants but might also remove essential minerals.
Appetite and thirst tend to diminish with age. This means that even when your body is craving fluids, you might not be aware of it—and you may drink less than you need to stay healthy. Older adults experience body composition changes over time that leave them with less water in their bodies to start with.
One of the easiest ways to test your hydration is through bathroom frequency and urine color. Your urine should be light yellow and you should be emptying your bladder on average 5-8 times per day. Another way to determine hydration levels (especially after a run) is a sweat test.
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.
The easiest way to know if you're drinking enough fluid is to look at the colour of your urine. If you're drinking enough water, your urine will be clear or pale yellow. A darker yellow means you aren't drinking enough water. People who drink enough water also usually have soft bowel movements.

However, there are recommendations for total water intake, which includes water consumed through all foods and beverages, such as plain water, fruits, and vegetables. A total daily intake of around 2.7 liters (91 ounces) for women and 3.7 liters (125 ounces) for men can meet most adults' needs (19).
According to the World Health Organization (WHO), an average adult needs to drink between 50 and 100 ounces (1.5 to 3 liters) of water per day. 64 ounces (1.8 liters) is considered ideal. The US Food and Drug Administration (FDA) recommends 90-125 ounces (2.7 to 3.7 liters) per day.
Research shows that milk is one of the best beverages for hydration, even better than water or sports drinks. Researchers credit milk's natural electrolytes, carbohydrates, and protein for its effectiveness.
