Both inside and outside the cells, water acts as a solvent to dissolve electrolytes like sodium, potassium, calcium, magnesium, chloride, bicarbonate, phosphate and sulfate, which are kept at very specific concentrations.Ībout 80 percent of our water intake comes from drinking fluids. Extracellular fluid is made up of blood, and the fluid found between cells in the interstitial tissue. Total body water can be subdivided into two major compartments: the fluid inside our cells, known as intracellular fluid, and fluid outside our cells, called extracellular fluid. Ultimately, maintaining the right balance of water in our body is what keeps us alive. Water can also help with weight loss and maintaining a healthy body weight - replacing sweetened drinks with water reduces calorie intake and drinking water before and during a meal can increase our sense of fullness and prevent overeating. Water forms the bulk of blood, which allows oxygen and glucose to move around the body, and it plays a role in eliminating toxins through urination. It’s critical for digestion: The water in saliva moistens food when we chew and it serves as a fluid environment in which digestive enzymes break down our meals. Staying hydrated is important because water does so many important things in the body.
