to·tal bod·y wa·ter

(tō'tăl bod'ē waw'tĕr)
Sum of intracellular and extracellular water (volume); about 60% of body weight.

total body water

includes the intracellular water and the extracellular water, the latter consisting of the interstitial or tissue fluid and the intravascular fluid or plasma. The extracellular fluids also contain the transcellular fluids that are formed by active transport processes and include saliva, cerebrospinal fluid, and the fluids of the eye and the secretory glands and so on. It may be ingested water or water produced by the body's metabolic processes (metabolic water).

Q. I have found that my body weight has high proportion of water in total weight.. I have found that my body weight has high proportion of water in total weight, and it makes me to take less water and there by increasing my thirst, which in turn stresses my body a lot, what can I do to reduce this problem…..?
