Water accounts for about 60 to 70 percent of our body weight. Men tend to have higher body water content due to greater muscle mass, compared to women who have more fat mass. A water molecule consists of one oxygen and two hydrogen atoms bound to each other by covalent bonds, which means that electrons are shared between atoms.
Oxygen is more electronegative than hydrogen, which causes a stronger attraction of electrons. This is the reason why oxygen bears a negative charge. Since hydrogen is losing the electron, it bears a positive charge. Therefore, a water molecule is considered polar (two different charged poles) with the sum of these poles being neutral.
