Total body water is the % of total weight that consists of water. Our bodies are comprised of 40-70% of water, and even slight changes in fluid balance can lead to drastic changes in performance and overall health. It is important to monitor and understand the individual’s hydration baseline and monitor closely to avoid dehydration.
Low. Your water % is lower than normal. It can lead to dehydration. Dehydration occurs when more water and fluids leave the body than enter it. Even low levels of dehydration can cause headaches, lethargy, and constipation.
Normal. Your water % is in a normal range. Water is essential for health. It helps to regulate temperature, hydrate skin, and lubricate joints. And there’s more: it helps maintain your blood pressure, flush body waste, and deliver oxygen throughout the body, among many other benefits.
High. Your water % is higher than normal. Too much water can dilute essential electrolytes in the blood, cause cells to swell, and put pressure on the brain.
You will find the total body water ranges in the table below.
