So how much fluid does the average, healthy adult living in a temperate climate need? 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.
For men, the Institute of Medicine (IOM) recommends a total of 13 cups (about 3 liters) of fluid each day. For women, they suggest 9 cups (a little over 2 liters) of fluid each day. Pregnant women should drink about 10 cups of water daily. Those who breastfeed need about 12 cups.
Drinking enough water offers health benefits, however, drinking too much water, such as 3-4 liters of water, in a short period leads to water intoxication. For proper metabolism, a normal human body requires about two liters of water.
There is no specific amount of water that is too much. But if you find yourself drinking a gallon of water or more a day, it's a good idea to speak with your healthcare provider. You can work together to figure out the right amount of fluid you should drink a day to stay hydrated.
“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.
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.
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.
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.
Drinking too much water can be dangerous
Drinking too much can disrupt your body's electrolyte balance, leading to hyponatremia, or low levels of sodium in your blood ( 21 ). Symptoms of hyponatremia include weakness, confusion, nausea, vomiting, and — in severe cases — even death ( 22 ).
But how much water is too much? "Drinking more than the kidneys can eliminate could cause hyponatremia in some people," says Hultin, noting that the kidneys can eliminate 27 to 34 ounces of water per hour, or a total of 676 to 947 ounces (20 to 28 liters) per day. More than that might put you in the danger zone.
Increasing water intake can bring many benefits to body health, especially weight loss and skin health. Although drinking 3 liters a day can help you meet your body's daily needs, this is not always the case and is possible for everyone.
As a general rule, you can use this simple calculation. Water (in litres) to drink a day = Your Weight (in Kg) multiplied by 0.033. For example, if you are 60kg, you should drink about 2 litres of water every single day.
You'll feel less hungry and may even lose weight. You'll probably experience more comfortable digestion (less heartburn). Bowel movements might be easier and more regular. Your teeth and gums will be healthier and more resilient.
Prevents Pimples and Acne. Certain kinds of toxins will clog your small pores on your epidermis and can cause issues like acne and pimples. By drinking more water, you ensure that you won't suffer from severe pimples and acne. The more hydrated your skin, the less your pores will clog.
As fluid intake increases, the amount of urine made will increase along with it. Because the bladder can only hold so much fluid volume, increasing water intake will increase the frequency of urination, and may make people with an overactive bladder more likely to leak.
People who drink too much water might gain weight suddenly due to swelling and excess water in the bloodstream. If you're drinking more than 10 cups of water each day and notice swelling or discoloration in your hands, lips, and feet, consider cutting back on your water intake and see if your symptoms subside.
Did you know that drinking 2 litres of water a day cleanses toxins from your body, gives you energy and helps with fatigue? Staying hydrated can bring a good dose of brain power and vitality to your day. It also helps your kidneys regain balance.
The Eatwell Guide says we should 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.
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.
Several other studies have monitored overweight people who drank 1-1.5 liters (34–50 oz) of water daily for a few weeks. They found a significant reduction in weight, body mass index (BMI), waist circumference and body fat ( 8 , 9 , 10 ).
Here's how it works: Your general water requirements can be determined using your current body weight. Most people need to drink roughly half of their weight (in pounds) in ounces. For example, a 200-pound adult needs approximately 100 ounces of water each 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.
