Do You Know How Much Water is in a Human Body?

Ever wondered how much water is in the human body? How does water function in our body? Why is water an essential part of our lives? Don’t worry, today we will learn everything about water and its functions.

Even though the amount varies according to the age and gender differences when you feel thirsty, did the question come to your mind that how much water you just dehydrated? Well, the answers that we are going to tell you might seem a bit shocking!

Stick to this article to the end and find out interesting information about water. And how much water a human body contains.

The Amount of Water Your Body Contains, How Much Water is in a Human Body?

When you were a newborn baby, your body contained the most amount of water that you will ever possess in a normal health condition. A newborn baby comprises about 78% of water. It is not a big deal especially when the baby just came from his/her mother’s womb, where he/she used to swim around. But as the years pass by, the baby loses water by 8%, which means within a year the body contains about 70% of water.

At the time of hitting puberty, your water levels will differ depending on the gender. As the women have more fatty tissue than the men, the body of an average girl contains about 55% water, while on the other hand, a boy contains 60%. It seems fair enough because the muscle that a boy has can carry more water than fat.

When you are an adult, you contain 60 percent water if you are a man. And if you are a woman, it’s around 50 percent for you. So, depending on the physical condition, weather, sex, and other issues, the amount of water varies a lot. Now the question you might ask is, where does all the water go? Well, two-thirds of the water is in your cells. The rest of the one-third of the water is in between your cells and blood.

Water in Your Organs

You will be further amazed to know how much of those water our organs have. The organs you have are of different moisture levels, so they always need to stay wet enough to properly function. You may think that your blood contains the most amount water than other organs. Surprisingly, your blood contains less liquid than your brain does.

The overall blood volume contains about 80% of water. Although, the most liquid portion of blood which is plasma, holds around 92% of that water. Your brain and heart are 74% water, and the kidneys have 79% of it. The liver is about to 86%, while the amount of liquid that your muscles have is 76% water. Skin and fat contain about 70% and 20% water respectively. Your bones are of just 31% water.

Remember the last time, when you felt thirsty like you could even drink a whole gallon of water? You will be astonished to know, at that time you just lost less than 3% water from your body. If losing3% of water makes you feel thirsty, what would happen if you lose 10% of water? You will not be able to move. And if it increases to the level of 12%, one has no chance except for dying.

Water Is an Essential Factor to Life

In life, water is an essential thing for survival. Without water, a human being (male or female) can live just for a few days. The water in the body depends on gender and different sex or age, and we can also say that the male body contains a higher percentage of water than a female body because of research. Females have a lot of fats in their bodies; due to that, they have less water than males. If we discuss the age factor, the percentage of water decreased year by year in both male and female bodies. We all know that newborn babies have a lot of water percentage or amount of portion in their bodies compared to adults.

Water in Newborn Babies

The water in newborn babies ranges from 64 % to 84%, and its average is about 74% which is just surprisingly excellent, and in adult age, the percentage is 43% to 70%. Its average is 60% and in the older age range is 47% to 67%, and its average is about 55% which is much lower than the other two which we have already discussed with you.

Water in the Male Body

In adult men, about 60 % percent of their bodies are of water. However, fat tissues do not have as much water as lean tissues. Now you are thinking about lean tissue, so we are here to guide you about skeletal tissues (includes many essential parts, including organs and bones). Being slender means you are within the optimal weight for your height with enough muscles to allow you to have no issues with physical activity. 

Water in the Female Body

Adult women average about 55% percent because women naturally have more fatty tissues than men. The percentage of water in a body varies according to the age of women and sex. Also, there is always more water in lean tissue than it is in fatty tissue. The female body contains a lower percentage of water than males.

In other words, can we say water is life?

Yes, we can say that water is life because water is an essential part of survival. In physiology, body water is the water content of a human body contained in the tissues, the blood, the bones, and elsewhere. The body water percentages are held in different fluid compartments, which add up to the total body water (TBW). Water makes up a significant fraction of the human body, both by weight and by volume of the body. Ensuring the right amount of body water is a part of the fluid balance, an aspect of homeostatic. Our bodies are roughly made up of 60% water. The amount of water in the body fluctuates with age, sex, and hydration levels. While the average percentage of a human body is around 60%, the rate can vary from roughly 45% to 75%.

 And as we all know that the skin is the body’s most prominent organ. That is why the importance of water is essential to keep our skin healthy. So the body needs water to keep the skin well, and the exact percentage of the fluid compared to the bodyweight is inversely proportional (opposite to one another). In simple words, you can say that if one object is increasing, the other object will automatically decrease the percentage of body fat.

 For example, a lean 70 kg (160lb) person has about 42% to 47% liters of water in their body. However, we know that everything in this world has advantages as well as disadvantages. So if more water enters a body than usual or is required, it may damage our body.

 As we know, excess of everything is terrible, so the excess amount of water in the body may damage different organs. Also, kidneys cannot overcome the extra amount of fluid. It begins to accumulate in the body, causing nausea, vomiting and diarrhea, and all-day headaches. Headaches also indicate both hydration and dehydration.

Function of Water

Now that we’ve covered the percentage of water in your body, you’re probably wondering how much water in the human body goes towards different functions. There are some amazing functions of water in your body. The water also helps your brain, spinal cord, and other organs to insulate by acting as a shock absorber. What if when you flush out your waste and toxins from the body, and there’s nothing like a bit of lubricate? Water even helps you in this matter, acting as a lubricant. It is excruciating to imagine the scene where you are doing it without getting help from water.

With the help of perspiration and respiration, water regulates the temperature of your body. Not only that, producing saliva, water keeps the food moist in your mouth for better mastication. Furthermore, water contributes to metabolizing your food, helping your digestion ability and also making your swallowing smooth.

Although your bones contain less water than other organs, bones are lubricated enough by the water, for which you can flexibly move your joints. Oxygen and nutrients are carried to your cells through the water. Cells are primarily dependent on water. You can survive without food for around a month, but you can hardly survive a week without water.

All the cells, organs, and human skin need water to function. Water has countless functions and you would be amazed to find those out. But as we don’t have much time for this debate so, let’s get straight to the point. Water serves as a lubricant for the body. It makes up saliva and the fluids surrounding the joints and also regulates the body temperature through perspiration. Here are some important ways water functions in our body.

Does Drinking Water Make Skin Glow?

 It’s a well known fact that keeping your skin supple and healthy requires water. While your skin will absorb some water when you wash it, it gets most of its hydration from water that you drink. We are told that drinking plenty of water is the key to youthful, plump, and clear skin, but is this the case? Drinking water is necessary for our bodies to run optimally and help the nutrients reach the skin. Having good blood flow and proper hydration is more important than surface absorption of water. The actual thing is that when you drink water, it doesn’t directly go to the skin or tissues. But it hydrates them, sucks them, and turns them into the bloodstream, and toxins are removed, or the kidneys filter waste fluids.
