How Much Water Should You Drink Per Day?
Health experts often recommend people to drink eight 8-ounce glasses of water per day. This is commonly known as the “8×8” rule. It may not apply to everyone, though. Your body is about 60 percent water. The body constantly loses water throughout the day, mostly through urine and sweat but also from regular body functions like breathing. To prevent dehydration, you need to get plenty of water from drink and food every day. There are many different opinions on just how much water you should be drinking every day. 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. As with most things, this depends on the individual. Many factors (both internal and external) ultimately affect how much water you need. This article takes a look at some water intake studies to separate fact from fiction and explains how to easily stay well hydrated for your individual needs.
How much water do you need? Share on Pinterest Ani Dimi/Stocksy United How much water you need depends on a lot of things and varies from person to person. For adults, the general recommendation from The U.S. National Academies of Sciences, Engineering, and Medicine is about: 11.5 cups (2.7 liters) a day for women
15.5 cups (3.7 liters) a day for men This includes fluids from water, beverages like teas and juice, and from food. You get an average of 20 percent of your water from the foods you eat (1, 2). You might need more water than someone else. How much water you need also depends on: Where you live. You will need more water in hot, humid, or dry areas. You’ll also need more water if you live in the mountains or at a high altitude ( 3 ).
You will need more water in hot, humid, or dry areas. You’ll also need more water if you live in the mountains or at a high altitude ( ). Your diet. If you drink a lot of coffee and other caffeinated beverages you might lose more water through extra urination. You will likely also need to drink more water if your diet is high in salty, spicy, or sugary foods. Or, more water is necessary if you don’t eat a lot of hydrating foods that are high in water like fresh or cooked fruits and vegetables.

You will likely also need to drink more water if your diet is high in salty, spicy, or sugary foods.

You may need more water in warmer months than cooler ones due to perspiration.
You may need more water in warmer months than cooler ones due to perspiration. Your environment. If you spend more time outdoors in the sun or hot temperatures or in a heated room, you might feel thirstier faster.
If you spend more time outdoors in the sun or hot temperatures or in a heated room, you might feel thirstier faster. How active you are. If you are active during the day or walk or stand a lot, you’ll need more water than someone who’s sitting at a desk. If you exercise or do any intense activity, you will need to drink more to cover water loss.
If you are active during the day or walk or stand a lot, you’ll need more water than someone who’s sitting at a desk. If you exercise or do any intense activity, you will need to drink more to cover water loss. Your health. If you have an infection or a fever, or if you lose fluids through vomiting or diarrhea, you will need to drink more water. If you have a health condition like diabetes you will also need more water. Some medications like diuretics can also make you lose water.
If you have an infection or a fever, or if you lose fluids through vomiting or diarrhea, you will need to drink more water. If you have a health condition like diabetes you will also need more water. Some medications like diuretics can also make you lose water. Pregnant or breastfeeding. If you’re pregnant or nursing your baby, you’ll need to drink extra water to stay hydrated. Your body is doing the work for two (or more), after all. Summary Many factors affect how much water you need to stay healthy such as your health, activity, and environment.
Does water intake affect energy levels and brain function? Many people claim that if you don’t stay hydrated throughout the day, your energy levels and brain function start to suffer. There are plenty of studies to support this. One study in women showed that a fluid loss of 1.36 percent after exercise impaired mood and concentration and increased the frequency of headaches ( 4 ). Another study in China that followed 12 men in university found that not drinking water for 36 hours had noticeable effects on fatigue, attention and focus, reaction speed, and short-term memory (5). Even mild dehydration can reduce physical performance. A clinical study on older, healthy men reported that just a 1 percent loss of body water reduced their muscle strength, power, and endurance (6). Losing 1 percent of body weight might not seem like a lot, but it’s a significant amount of water to lose. This usually happens when you’re sweating a lot or in a very warm room and not drinking enough water. Summary Mild dehydration caused by exercise or heat can have negative effects on both your physical and mental performance.
Does drinking a lot of water help you lose weight? There are many claims that drinking more water may reduce body weight by increasing your metabolism and curbing appetite. According to a study, drinking more water than usual correlated to a decrease in body weight and body composition scores. ( 7 ). Another review of studies found that chronic dehydration was associated with obesity, diabetes, cancer, and cardiovascular disease ( 8 ). Researchers in another older study estimated that drinking 68 ounces (2 liters) in one day increased energy expenditure by about 23 calories per day due to a thermogenic response, or a faster metabolism ( 9 ). The amount was incremental but could add up over time. Drinking water about a half hour before meals can also reduce the number of calories you end up consuming ( 10 ). This might happen because it’s easy for the body to mistake thirst for hunger. One study showed that people who drank 17 ounces (500 mL) of water before each meal lost 44% more weight over 12 weeks, compared to those who didn’t ( 11 ). Overall, it seems that drinking adequate amounts of water, particularly before meals, may give you a boost in managing appetite and maintaining a healthy body weight, especially when combined with a healthy eating plan. What’s more, drinking plenty of water has a number of other health benefits. Summary Drinking water can cause slight, temporary increases in metabolism, and drinking it about a half hour before each meal can help you eat fewer calories. Both of these effects can contribute to weight loss in some people.
Does more water help prevent health problems? Drinking enough water is required for your body to function in general. Several health problems may also respond well to increased water intake: Constipation. Increasing water intake can help with constipation, a very common problem (12, 13).
Increasing water intake can help with constipation, a very common problem (12, 13). Urinary tract infections. Recent studies have shown that increasing water consumption may help prevent recurring urinary tract and bladder infections ( 14 , 15)
Recent studies have shown that increasing water consumption may help prevent recurring urinary tract and bladder infections ( , 15) Kidney stones. An older study concluded that high fluid intake decreased the risk of kidney stones, though more research is needed ( 16 ).
An older study concluded that high fluid intake decreased the risk of kidney stones, though more research is needed ( ). Skin hydration. Studies show that more water leads to better skin hydration, though more research is needed on improved clarity and effects on acne ( 17 , 18 ) Summary Drinking more water and staying adequately hydrated may help with some health problems, such as constipation, urinary and bladder infections, kidney stones, and skin dehydration.
Do other fluids count toward your total? Plain water is not the only drink that contributes to your fluid balance. Other drinks and foods can have a significant effect. One myth is that caffeinated drinks, such as coffee or tea, don’t help you hydrate because caffeine is a diuretic. In fact, studies show that the diuretic effect of these beverages is weak, but they can cause extra urination in some people ( 19 ). However, even caffeinated drinks help add water to your body overall. Most foods contain water in varying levels. Meat, fish, eggs, and especially fruits and vegetables all contain water. Together, coffee or tea and water-rich foods can help maintain your fluid balance. Summary Other beverages can contribute to fluid balance, including coffee and tea. Most foods also contain water.
Indicators of hydration Maintaining water balance is essential for your survival. For this reason, your body has a sophisticated system for controlling when and how much you drink. When your total water content goes below a certain level, thirst kicks in. This is carefully balanced by mechanisms similar to breathing — you don’t need to consciously think about it. Your body knows how to balance its water levels and when to signal you to drink more. While thirst may be a reliable indicator of dehydration, relying on feeling thirsty may not be adequate for optimal health or exercise performance ( 20 ). At the time thirst strikes, you may be already feeling the effects of too little hydration such as fatigue or headaches. Using your urine color as your guide can be more helpful to know if you’re drinking enough (21). Aim for pale, clear urine. There really is no science behind the 8×8 rule. It is completely arbitrary (1, 22 ). That said, certain circumstances may call for increased water intake. The most important one may be during times of increased sweating. This includes exercise and hot weather, especially in a dry climate. If you’re sweating a lot, make sure to replenish the lost fluid with water. Athletes doing long, intense exercises may also need to replenish electrolytes, like sodium and other minerals, along with water. Your water need increases during pregnancy and breastfeeding. You also need more water when you have a fever and when you’re vomiting or have diarrhea. If you desire to lose weight, consider upping your water intake too. Furthermore, older people may need to consciously watch their water intake because the thirst mechanisms can start to malfunction with aging. Studies show that adults over 65 years old are at a higher risk for dehydration (23). Summary Most people don’t need to focus too much on their water intake, as the body has an automatic thirst signal. However, certain circumstances do call for increased attention to how much water you’re drinking.
Drink 8 Glasses of Water a Day: Fact or Fiction?
You’ve probably heard that you need to drink eight 8-ounce (240-ml) glasses of water each day. That’s half a gallon of water (about 2 liters). This claim has become widely accepted as fact, and it’s very easy to remember. But is there truth to this advice, or is it just a myth? This article reviews the evidence behind the “eight glasses a day” rule and how much water we need each day. Share on Pinterest Marc Tran/Stocksy United
Evidence for drinking 8 glasses of water each day It’s hard to pinpoint exactly where and when the “eight glasses per day” rule originated. There are theories that it may be based on a fluid intake of 1 ml per calorie of food consumed. For someone eating a diet of 2,000 calories per day, this adds up to 2,000 ml (roughly 64 ounces), or eight 8-ounce glasses. However, a growing body of research suggests that this broad recommendation may actually be too much water for some people and not enough for others. While there are certainly circumstances in which water needs increase, healthy people generally don’t need to be consuming water in such large quantities. On the other hand, not drinking enough water can cause mild dehydration, defined as the loss of 1–2% of body weight due to fluid loss. In this state, you may experience fatigue, headache, and impaired mood ( 1 ). But in order to stay hydrated and avoid mild dehydration, you don’t need to rigorously follow the eight glasses rule — simply follow your thirst. Summary There is no scientific evidence to support the 8×8 rule. Water needs vary by individual, and you should let thirst guide your intake.
Foods and beverages other than water can contribute to hydration It’s not just plain water that supplies your body with water. Other beverages, like milk and fruit juice, count as well. Contrary to popular belief, caffeinated beverages and mild alcoholic drinks such as beer may also contribute to fluid intake, at least when they’re consumed in moderation ( 2 , 3 , 4 ). Many of the foods you eat also contain significant amounts of water. How much water you get from food depends on the amount of water-rich foods you eat. Fruits and vegetables are particularly rich in water, and foods like meat, fish, and eggs also have a relatively high water content. For example, watermelon is 91% water, and eggs are 76% water ( 5 , 6 ). Lastly, small amounts of water are produced within your body when you metabolize nutrients. This is referred to as metabolic water ( 7 ). People who don’t get much water from foods need to drink more than those who eat more water-rich foods. Summary Besides water, other foods and beverages you ingest also contribute to your overall daily intake of fluids and help keep you hydrated. Some water is also created within your body through metabolism.
Drinking enough water has some health benefits You need to drink enough water to stay optimally hydrated. Generally speaking, that means replacing the water you lose through breath, sweat, urine, and feces. Drinking enough water may offer health benefits, including: Weight loss. Drinking enough water may help you burn more calories, reducing appetite if consumed before a meal and lowering the risk of long-term weight gain ( 8 ).
Drinking enough water may help you burn more calories, reducing appetite if consumed before a meal and lowering the risk of long-term weight gain ( ). Better physical performance. Modest dehydration may impair physical performance. Losing only 2% of your body’s water content during exercise may increase fatigue and reduce motivation (9).
Modest dehydration may impair physical performance. Losing only 2% of your body’s water content during exercise may increase fatigue and reduce motivation (9). Reduced severity of headaches. For those prone to headaches, drinking additional water may reduce the intensity and duration of episodes. In dehydrated people, water may help relieve headache symptoms ( 10 , 11 ).

How much water should you drink each day? There is no single answer to this question. However, the National Institute of Medicine has set an Adequate Intake (AI) level for total water and total beverages. The AI refers to a level that is assumed to meet the needs of most people. The AI for total water (including water from food, beverages, and metabolism) and total beverages (including water and all other drinks) is (15): Total water Total beverages Males, ages 19–70 125 ounces (3,700 ml) 101 ounces (3,000 ml) Females, ages 19–70 91 ounces (2,700 ml) 74 ounces (2,200 ml) While this may certainly be used as a guideline, there are a number of factors, both inside your body and in your environment, that influence your need for water. Body size, composition, and activity level vary greatly from person to person. If you’re an athlete, live in a hot climate, or are currently breastfeeding, your water requirements increase ( 16 ). Taking all this into account, it’s clear that water needs are highly individual. Eight glasses of water per day may be more than enough for some people, but it may be too little for others. If you want to keep things simple, just listen to your body and let thirst be your guide. Drink water when you’re feeling thirsty. Stop when you’re not thirsty anymore. Make up for fluid loss by drinking more during hot weather and exercise. However, keep in mind that this does not apply to everyone. Some older adults, for example, may need to consciously remind themselves to drink water, because aging can reduce the sensation of thirst ( 17 ).
How Much Water Should You Drink Every Day?
About 60% of your body weight is made of water. You need it for every single body function. It flushes toxins from your organs, carries nutrients to your cells, cushions your joints, and helps you digest the food you eat. If you don’t get enough water, you can become dehydrated. Severe cases of dehydration can cause dizziness, confusion, and even seizures. That’s why it’s important to get the water as your body needs every day. No set amount is right for everyone. How much you need can depend on your size, how much exercise you do, how hot the weather is, and other things. Your doctor can help you determine what’s right for you.
How Much Water Does Your Body Need Each Day? We’ve all heard that 8 glasses of water each day is best. But the truth is, how much water you need varies. But there are some basic guidelines: 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.
If you’re outside on a hot day, or doing something that makes you sweat a lot, you’ll need to drink more fluids to stay hydrated. The same is true if you have an illness that causes you to throw up, have diarrhea, or run a fever. If you have a condition like heart failure or a particular type of kidney disease, you may need to limit your fluid intake. Talk to your doctor about what’s right for you.
