Why we drink water when thirsty

Wonder why both animals and humans tend to gulp water or drink water very quickly when thirsty? Apparently, the speed of fluid intake inhibits the thirst neurons, which get activated when a person is thirsty, leading to feeling of satiation.

The feeling of thirst arises when the volume of blood reduces or when salts such as sodium and potassium are high in the blood. Though it takes over 15 minutes for the water to be absorbed into the blood, the brain signals to stop drinking after a few gulps though the water has only reached the stomach.
