Body Water Percentage: What It Is and Why It Matters
Water is the most abundant substance in your body, taking up the largest percentage of total body weight and making it one of the most important things to understand about your overall health. But, what does your body water percentage say about you? And what is intracellular vs. extracellular water?
In this article, we will answer all of these questions, as well as give you actionable tips for improving your water intake. Let’s get started!
What Is Body Water Percentage?
Body water percentage is the amount of water your body contains, as compared to the amount of fat and other tissue. The average percentage of body water in humans varies according to age, gender, and fitness level.
Age
Newborn babies have higher levels of body water than adults. During birth, babies are born with a body water percentage of up to 78%. However, this percentage drops to 65% as they turn one year of age.
Gender
Adult women tend to have a lower percentage of body water, around 55%, compared to men, who have about 60%. This is because women have more fat tissue than men do. Fat tissue has a lower water content than muscle tissue, which means that women tend to have less overall body water than men do.
Fitness
People who exercise regularly have higher levels of body water because their bodies are made up primarily of lean muscle tissue rather than fat cells, which contain less water than muscle cells.
Intracellular Water
Intracellular water is found inside cells and has several functions, including supporting metabolic reactions and maintaining the pH of cells. It can also assist with cell growth, being used as an energy source and helping transport nutrients for some cells.
Intracellular water contains low levels of electrolyte sodium ions and high electrolyte potassium; these are responsible for maintaining the cell’s overall electrical charge. In addition, intracellular fluid also contains small amounts of other dissolved minerals, such as calcium and magnesium ions.
Extracellular Water (ECW)
Extracellular water is the water outside of the cells. ECW makes up about one-third of total body water.
Most of the extracellular water is in blood vessels and transcellular fluid, but some also exist in interstitial fluid. This fluid helps to move nutrients and wastes through tissues. The extracellular fluid contains several types of substances that are important for maintaining health in humans. These include ions (such as sodium and potassium), hormones, enzymes, antibodies, and white blood cells.
What Is a Healthy Water Balance?
A healthy water balance is when your body has the right ratio of intracellular and extracellular water. The estimated normal ratio of intracellular water vs. extracellular water is 3:2.
When the ratios change, this can significantly affect your overall health, depending on the type of water that causes the imbalance.
5 Tips to Improve Your Water Intake
- Drink a glass of water when you wake up as it will help you kickstart your day with hydration.
- Drink water instead of other beverages that contain calories.
- Drink water before meals to help you feel full.
- Keep a glass of water with you at all times during the day, so you’ll be able to take a sip whenever you need it.
- Set reminders on your phone to drink more water throughout the day.
Why Does Knowing Your Body Water Percentage Matter?
Your body’s water percentage is a measure of your hydration levels. It’s used to determine if you have adequate water in the body, which is necessary for proper bodily function.
Listed below are some health benefits to knowing about your water levels.
Helps You Avoid Dehydration
Knowing your percentage of body water can help you avoid dehydration. Dehydration occurs when there isn’t enough water in the body tissues to perform at their best. This can lead to fatigue, headaches, dizziness, and other symptoms.
Helps You Maintain a Healthy Weight and Body Composition
Knowing your body water percentage can help you determine if you’re at risk for obesity or any other weight-related illnesses. Reaching for water regularly enough to remain hydrated also helps cut out sugary or calorie-dense drinks that could increase your risk of obesity.
A Good Indicator of Your Overall Health
A high percentage of body water can indicate that you are well-hydrated and have a healthy diet. On the other hand, a low percentage of body water may indicate that you aren’t drinking enough water or eating enough fruits and vegetables.
Helps You Understand How Much Fluid You Need in a Day to Stay Healthy
Knowing your intracellular water vs. extracellular water ratio and body water percentage can help you understand how much fluid you need in a day to stay healthy. The amount of water needed varies from person to person based on age, gender, activity level, and other factors—but having a baseline understanding of what’s normal for you will help ensure that you’re getting enough of it every day!
Your body water percentage says a lot about you! It tells us whether or not you’re eating enough fruits and vegetables, how hydrated your cells are, and how much water you need to drink. It’s also a good indicator of overall health.
