WATER CONTENT IN THE BODY

Water is the most important single component of body weight. Water represents more than

half of the total weight and almost two thirds of the weight of the body (muscle) tissue. Water

plays many important roles in the human body. All cells in the body - the skin, glands, mus-

cles, brain or any other, may function properly only when the body is supplied with suﬃcient

amount of water. Water also plays an important role in regulating body temperature, particu-

larly through sweating.

The knowledge of the level of fat and water in the body can provide some kind of guidance

when adjusting the diet, exercise programme and ﬂuid intake and thus can contribute to the

improvement of heath condition. The results of water measurement depend on the propor-

tion of fat and muscles in the body. If the proportion of fat is high or the proportion of muscles

is low, the results of water measurement may be low. Please note that the measurements of

body weight, fat and water content provide useful information to maintain a healthy lifestyle.

THE AMOUNT OF MUSCLE TISSUE IN THE BODY

This function indicates the amount of muscle tissue in the body. The muscle mass includes

skeletal muscles, smooth muscles (such as heart muscle and gastrointestinal tract muscles)

and the water contained in these muscles.
