Why are we advisted to drink isotonic fluid?
Isotonic drink (Zporto) can protect our body from dehidration optimally because isotonic fluid easy to move into the cell. Another reason is, isotonic”s electrolit composition will remain longer inside the cell (guyton, 2007). In dehydration, we should use isotonic drink because of that reason. If we drink plain water, the water will replace our body fluid rapidlly but we also will loss that fluid quickly through urine. Its interesting “why after we drink an amount of water when loss a lot of water (dehydration), we often want to go to bathroom”. Its happend because water without electrolit will cause osmotic pressure decrease so our body will give respons. Respons are need for keep stability of body osmotic pressure. One of that respons to increase osmotic pressure is increasing urination process. Movement of the water between cell which faster than isotonic fluid result poor absorption process. This is clear why if we drink plain water less effective than drink isotonic fluid.
