It is possible to drink water too fast at a time and lose more water when you are thirsty. The balance between water and osmotic pressure is related to the body's regulation of water intake and discharge. The kidney mainly controls the discharge of water through the synthesis and release of antidiuretic hormone. When drinking too much water, the body fluid volume increases, the osmotic pressure decreases, and the kidneys excrete too much water through urine dilution. So the next time you drink water, slow down a glass of water and drink it several times, just a few minutes apart each time.
