Why do humans have to drink?
A human being consists of about 70 % of water. It is found in cells, blood, in the tissue and the lymphatic system. Water enables the metabolic process due to its function as means of transport and solvents. An optimal intake of nutrients, removal and excretion of waste products become possible. Furthermore, water is responsible for the regulation of our body temperature.
Our body loses fluids due to breathing, sweating and excretion. This loss is balanced by drinking. Now, when we don’t drink enough a lack of fluids arises. This impairs the function of our brain, kidneys, digestion, mucous membranes and eyes.

How much and how often should we drink?
On an average, an adult needs from 1.5 to 2.5 liters of fluids. About one liter comes with our food. The rest should be taken in throughout the day. Physical activity and warm days might increase the needed amount.
