Understanding body water percentage: a significant health indicatorA healthy water percentage is essential to your body’s functions. But why is hydration so essential, and is there an ideal body water range? How can you calculate your body water percentage? What are the signs of dehydration and excess body water? Read on to find out. What is the ideal body water percentage?Body water declines as you age, but it will remain above 50 percent for most, if not all, of your lifetime. The normal range for adult women varies between 45% and 60%. For men, the ideal body water percentage fluctuates between 50% and 65% of the total body. In babies, that number is much higher. The norm is considered to be between 75% and 78%, dropping to 65% by one year of age. Keep in mind, too, that body water can change during pregnancy. One study in the American Journal of Clinical Nutrition, which used bioelectrical impedance to measure total body water in pregnant women, found that “TBW increased significantly during pregnancy, then decreased postpartum.” How is body water usually measured?Body water percentage can be measured using several methods. For example, in a method called dilution, or hydrometry, the person being measured provides body fluid samples in a clinical setting. These samples are analyzed for isotope levels to calculate total body water and body fat mass. Another method, bioelectrical impedance analysis, a feature available in some smart scales, can measure the percentage of water in your body as part of your total body composition. If you want to estimate your body water, you may want to try the Watson formula, reported in a 1980 study entitled “Total Body Water Volumes for Adult Males and Females Estimated From Simple Anthropometric Measurements” in the American Journal of Clinical Nutrition. Watson formula for men2.447 – (0.09145 x age) + (0.1074 x height in centimeters) + (0.3362 x weight in kilograms) = total body water (TBW) in liters Watson formula for women–2.097 + (0.1069 x height in centimeters) + (0.2466 x weight in kilograms) = total body weight (TBW) in liters You can find many body water calculators that use this method. Although many other formulas are available, some studies, such as a 2001 report in Nephrology Dialysis Transplantation, have found that the Watson formula is the most accurate. How much water should I drink?To maintain body water in a healthy range, some experts recommend drinking 11 cups of day for women and 16 cups a day for men, but keep in mind: While staying hydrated is important, watch out for sugar-sweetened fruit juices and sodas. High-sugar diets are linked to an increased risk for heart disease, obesity, high blood pressure, Type 2 diabetes, and other conditions. Water requirements may change during exercise. Some research has shown that athletes tend to underestimate the amount of water they need to stay hydrated. As a guideline, WebMD suggests drinking 15 to 20 ounces of water 1 to 2 hours before your workout, between 8 and 10 ounces 15 minutes before you begin your workout, and another 8 ounces every 15 minutes during your workout. If you’re sweating heavily or losing weight during your workout, you may need to drink more. What are the signs of dehydration?Body water deficit can be dangerous. Symptoms of mild or moderate dehydration include thirst, headache, dry mouth, muscle cramps, and dark yellow urine. You may also not urinate very much. Symptoms of severe dehydration in adults may include dizziness, rapid heartbeat or breathing, very dry skin, sleepiness or lack of energy, and fainting. Symptoms in babies and small children may differ, and include no tears when crying, dry diapers for 3 hours or longer, dry mouth or tongue, and sunken eyes. Severe dehydration is a medical emergency and should be treated immediately. What are the risks of dehydration in adults?Dehydration can lead to serious consequences, including heat injury, seizures, urinary and kidney problems, and hypovolemic shock, when low blood volume causes a drop in blood pressure and oxygen in your body. If left untreated, it can lead to death. Body+ is an advanced Wi-Fi smart scale that performs highly accurate bioelectrical impedance analysis every time you step in.

Which of the following individuals would have the highest percentage of body water?Babies and children have a higher percentage of water than adults. When babies are born, they are about 78 percent water, but this falls to 65 percent by the age of 1 year. Fatty tissue has less water than lean tissue. Men have more water than women, as a percentage.
