What is Body Water Percentage?

Your body percentage is a measure of the total amount of water in your body which is expressed in terms of percentage of your total body weight. The human body should have at least 50% body water percentage for it to work properly and avoid dehydration. However, the percentage of water may differ based on the age, gender, and fitness level of the individual.

Newborn babies have three-fourths of their body weight consisting of water which makes it about 78%. After one year of age, this percentage reduces to 65%.

Adult men have a body water percentage of about 60% while women tend to have a lower body water percentage of about 55%. This difference is because women have more fatty tissues that have lower water content.

People who exercise and keep their body weight in check using personal scales have high fitness and thus a higher body water percentage since their muscles are lean and there are minimum fat cells.

Ideal Body Water Percentage

Human body water percentage declines with age. However, it should stay above 50% at all times for the healthy functioning of your mind and body.

The ideal body water percentage for adult men varies between 50 and 65% while for women it is between 45 to 60%. For people with real athletic bodies, the ideal water percentage can be about 5% higher than an average adult. For babies, the ideal body water percentage is between 75 to 78% before one year of age.

The Calculation of Your Body Water Percentage

To find your normal body water percentage, you can either use an online body water calculator or use the Watson formula. You can compare the result with a body water percentage chart to figure out if you are in a healthy range or not.

Dehydration occurs when the amount of water in your body is not sufficient. If not taken care of, it can lead to fatigue, dizziness, and headaches. By knowing your body water percentage, you can easily figure out whether there is a need for you to consume more fluids. This can help you avoid dehydration and its related side effects.

  1. Helps Maintain a Healthy Weight and Body Composition

Body water percentage can also help you stay lean and fit. It can indicate whether you are getting obese or not. If your body water percentage is very low then a smart weighing scale will probably show you are overweight and you need to cut down your diet and adopt a healthier lifestyle. This way it will be possible for you to maintain a healthy body shape and composition.
