The Water Intake Calculator will help assist in understanding one’s potential daily intake of water given the activity level. There are three levels to choose from including one’s climate/environment, and weight, which aides in an individual’s water consumption by weight. One essential thing to remember is that this is a water consumption daily calculator and it is supposed to be spread throughout the day and not to be consumed all at once. Drinking too much water consumption all at once could have severe bodily effects. How much water should you drink per day, or how much water should I drink per day can vary widely.

Facts about Water Consumption

Water Intake Calculator

Did you know that proper human water consumption for the human brain consists of up to 70% water and that the body is 50%-65% water? Think of your body like an automobile. Would you want low-quality fluids in your car that will hinder its performance and potentially damage car parts? Would you not want the best for it? Think of your body the same way as wanting high water quality! Water is natural for your body where unnatural added chemicals are not and can be viewed as water pollution for your body.

Best Water To Take

The best drink for personal water consumption for one’s body is pure water from a clean water supply. Without it, one will not survive long. Water is far better for hydration than unnatural substances like soda, alcohol, coffee, many juices, etc. Clean safe water is the best thing for one’s body because it is natural and will not dehydrate the body like unnatural substances might.

Benefits of drinking Water

If you are not drinking water for your recommended daily water consumption, you may not realize what you’re missing out on basically all of the benefits of drinking water. For example, the skin may appear to look clearer and more youthful than before because of knowing how much water to drink a day. The body may also release excess retained water it was holding because it was dehydrated for so long.

The appearance of weight loss and water consumption may work wonders for your appearance in many ways. Your mind will have clean water fluid cycling through its core thus potentially creating improved brain function. These are just some examples of the health benefits of water. The water usage calculator for water intake of how much water should you drink in a day is not a weight loss calculator but can help give the appearance of weight loss given the recommended water consumption per day.

General water drinking recommendations

Below chart shows the general recommended amount of water intake based on recommendations from European Food Safety Authority (EFSA) and the U.S. Institute of Medicine (IOM).

Water intake is in L/day (liters per day / litres per day).

What is Water?

Looking at the question from a scientific perspective, and as part of many water facts, can best be described as, “the compounds of pure liquid hydrogen and oxygen and represents H2O, or two particles of hydrogen for every one particle of oxygen for a total of three particles,” as a chemist would state. Many know water by its other names which include aqua, Adam’s ale, and aqua pura just to mention a few. One of the many facts about water is that it came to the ground and formed lakes, oceans, and aquifers, it came from the clouds in the form of rainwater or snow and through absorption was consumed by Mother Earth. There are many facts about water and one of those facts on the water is much older, it came from space in the form of Ice.

Why do we need water?

Many creatures and beings, including you, reading this right now on the other side of your screen, absorb water from what our planet provides (whether it be by food or drink) into their bodies and evacuate this fluid from excrements of urine, feces, and through sweat, tears, breathing, and saliva. In short, the importance of water and the personal uses of water are many for all of us, but if we don’t have it, we will not live long without it.

As mentioned, when we eat food our bodies take and absorb the water from that food. For Example, an apple consists of 80% water. One’s personal water calculation formula will fluctuate because of the water intake from the apple. One should remember that the daily water intake calculator does not account for how much water should you drink a day from food intake, and does not calculate the user’s average daily water consumption from eating various types of food.

How much water should I drink per day?

How much water to drink a day is a question that does not necessarily have a set amount of water consumption for every individual to figure out how much water should you drink a day. According to The National Academies Institute of Medicine (IOM) press release from February 11, 2004, men should consume 3.7 liters and women should consume 2.7 liters of fluids a day which helps assist in answering the question of how much water should I drink a day.

These figures for how much water to drink a day are given to healthy individuals with a sedentary lifestyle that live in temperate climates. This fluid intake considers intake of food moisture like that of an apple consisting of 80% water, and from water/beverages which counts towards how much water to drink a day. The IOM also takes note of proper salt intake given an individual water intake because if one has little to no salt in their system they could die from water intoxication called hypernatremia, which is an imbalance of the number of electrolytes in the body and should certainly be noted for how much water should you drink per day.

How Much Water in Foods

All foods will contain some sort of water moisture within them. Thus, the water intake calculator is also including one water from foods. Remember if you are thinking to yourself “how much water to drink a day” that you need to also know about how much water in foods as well. Below are some examples of various foods and the percentage of water by a weight inside of the food item.
