Drinking over 100 ounces of water may seem impossible at first, but with these easy tips you can reach your goal in no time.
What are the benefits of drinking enough water daily?Water is essential for our bodies to functions correctly and efficiently. It’s vital to our health and can have a huge impact on our overall health and wellness. Most of us know this, but do you actually know why water is so important. Here are the main benefits of staying hydrated:
How much water should I drink to try and lose weight?Let’s start out by being clear that drinking water alone will likely not lead to weight loss. However, the benefits of drinking water can help support and encourage weight loss. First, water helps us to feel full and satiated. When we are hydrated, we tend to eat less since we don’t confuse signs of dehydration with signs of hunger. Many people actually report feeling hungry when they are in fact dehydrated. Another added benefit of drinking water is that it is less likely that someone will overeat. When your stomach is filled with liquid from drinking water, it is less likely you will eat too much or mindlessly snack throughout the day. Lastly, if you are focused on drinking more water, you are less likely to reach for sugary drinks and beverages with empty calories. Swapping in water for higher calorie beverages is a great way to lose weight. More Questions and Answers About How Much Water to DrinkWhat liquids count towards your daily water goal?Pretty much all liquids count towards your daily water intake goals. This includes sparkling water, juice, milk, tea, coffee, smoothies, and even soda and diet soda. However, the best and most affordable option is always plain water. And it better for your body than other beverages according to this Harvard study. A few notes about caffeine. For a long time, people believed that drinking caffeinated beverages like coffee and tea, actually counted against your daily water intake since they are diuretics. However, recent studies suggest that this might not actually be the case. One other important note, food also contributes to your daily water goals. Some foods, like watermelon, is almost 100% water and therefore counts as well. Since this can be hard to track, just think of food as extra water you are having every day instead of trying to track it. How much water is too much?Many people wonder if there is actually a point where you can drink too much water. There are some rare cases of someone over-hydrating, known as hyponatremia. However, it is very rare and usually only seen in endurance athletes who are over-drinking while doing very intense exercise or in older adults with certain health conditions. For the average person, this is normally not a concern. Is drinking a gallon of water bad for you?Water poisoning or water intoxication is a condition where someone drinks too much water in a short period of time and their cells become imbalanced due to a loss of sodium. It is a serious condition but extremely rare. General guidelines suggest that you shouldn't drink more than 27-33 ounces of water per hour. This means drinking a gallon of water in an hour wouldn’t be recommended. Any type of water challenge could potentially be dangerous and it is always best to listen to your body. How much water do you really need?At the most basic level, you should be drinking enough water every day that you do not show any symptoms of dehydration and that your body is functioning well. There is no exact number for everyone since it varies based on your body, activity level, diet, climate, and more. Generally speaking, doctors recommend that you get at least 6 cups of water daily at a minimum but most people should be drinking more than that. One easy indicator is urine. Your urine should be fairly frequent and like yellow or clear in color. Darker or smelly urine is an indicator of dehydration and usually indicated you should be drinking more water. Does water affect your energy levels?Water can have a huge impact on energy levels. People who are dehydrated report feeling more tired, sluggish, and lethargic. Staying hydrated helps keep your cells functioning properly and helps energy levels stay high. In fact, it is one of the most recommended tips for boosting energy levels quickly. Does water intake affect brain function?Water and proper hydration have been shown to greatly benefit brain function. Specifically, staying hydrated can boost mood and mood stability, improve concentration, improve cognition, aid memory, prevent headaches, and even reduce stress. How can I tell if you are dehydrated?Here are some of the most common symptoms of dehydration:
Should I drink 8 glasses of water daily? What about the “8 by 8” rule?To help people have a tangible amount of water to focus on, there was a push to recommend that the average person drink 8 glasses of water by 8 PM daily. This would mean that you drank at least 64 ounces of water daily. There is no solid evidence suggesting that this is, in fact, the right amount, but it is probably a good recommendation for a minimum amount. Depending on your lifestyle, body type, diet, age, and more - this will vary. What factors affect how much water you need daily?The amount of water someone needs daily depends on a number of different factors. Here are the most common factors that affect water needs.
How do you know if you are well hydrated?The easiest way to know that you are well hydrated is to pay attention to your urine. Generally speaking, it should be light yellow or clear without too much of a smell. Thirst is another indicator, but many people confuse this with hunger. What about caffeine? How does it affect water intake and hydration?There used to be a common belief that caffeine counted against hydration since it is a diuretic. However, recent studies have shown it may not affect hydration as much as was previously thought. With that said, water is always the best option when trying to stay hydrated. How much water do you need during exercise?It is recommended that you drink water before, during, and after exercise. For most exercise, plain water will do. Some people recommend drinking an electrolyte drink after doing any vigorous exercise for an hour or more to replace lost electrolytes. One other note, drinking too much water too fast during exercise can cause cramps and stomach pain. It is best to sip slowly while working out in most cases.

Savannah March 25, 2022 - 10:48 the average for your weight alone would be 100 ounces. However, if you are active for about an hour or so everyday, that would equal your 128 ounces.

Amy April 6, 2021 - 20:01 Add a Rating: 5 Thank you for making this calculator! It has been very helpful. Ever since my gallbladder surgery a couple weeks ago I’ve been drinking a lot of water! And Pedialyte too. I seem to can’t stay hydrated long enough. Wake up with no voice and my lips are constantly dry and the headaches are horrible. I see the surgeon again to talk about this dehydration issue and figure out what’s going on. At least I’m not insane I literally am drinking 117 oz of water a day and I thought that was a bad thing but according to your calculations it is a good thing. Before the surgery I could hardly get down to 6 oz of water a day so at least I’m getting healthier with my water intake. Thanks again! Are you sure you want to delete your comment?

Jenny Exner January 28, 2019 - 13:57 That is nowhere near enough water for a person who works in a hot and dry environment. Nevermind taking into consideration: height (along with weight), sodium intake, smoker/non-smoker, diet (foods high/low in water), alcohol consumption, activity levels, medications and/or vitamins and supplements that might require more or less water intake. There's SO much to consider - this calculator is a great suggestion, but nowhere near accurate for every gender and size of human. Are you sure you want to delete your comment?

Alex July 22, 2018 - 02:46 You are dizzy because you are way under your water need - yes you will loose salt through sweat.. but you also loose water through sweat - the more you sweat the more you need water. 40oz for 160lbs is WAY to little.

I lose so much salt and vitamins I get dizzy and black out. And I wake up in the night with a full bladder. You should just about drink a cup of water with each meal. its not rocket science.

Annie July 2, 2018 - 10:57 Add a Rating: 2 If you're drinking enough water for your body AT A HEALTHY WEIGHT, you're drinking enough water. Increasing intake beyond what the kidneys can process (approximately 3.5L/hour) is harmful and potentially deadly. The way to calculate the amount of water to drink is to find a healthy weight for your height & multiply it by .5. Of course, your intake might go up with added exercise or in hot weather but intakes above twice that can deplete vital nutrients and more than that can cause hyponatremia, which is extremely dangerous.

Omatiklan May 7, 2018 - 12:19 First, I think your chart is a great starting point for healthy hydration. But I'm wondering, what's your source for this chart and calculation? Most clinicians, researchers and even U.S. agencies (i.e., FDA, CDC, USDA, OSHA, etc) all distance themselves from a quantity-specific recommendation since hydration needs are wildly variable from person to person and from one environment to another.

How much water should a 50kg person drink per day?A more calculated way to look at it is – drink a litre of water per 25kg of bodyweight, so if you weigh 50kg that's around 2 litres of water per day and if you weigh closer to 75kg you should be drinking broadly 3 litres per day. If this is more than you are used to, it is probably wise to step your intake up slowly.
