This Is How Our Brains Know , the Amount of Water We Need When We’re Thirsty.<br />When we're thirsty, we drink, right?.<br />A recent study says it <br />might not be that simple.<br />The study, published in the science <br />journal 'Nature,' finds the brain and <br />body work together in a complex way to <br />gauge when we need to hydrate.<br />Experts say the human body has several thirst-related checkpoints, which the brain utilizes to process how much water we need.<br />As it can often take water more than <br />15 minutes to absorb into the bloodstream, <br />these checkpoints are crucial to our health.<br />Experts say one of the first checkpoints <br />is when water hits your mouth, giving <br />"...your brain a refreshing feeling.".<br />The next checkpoint, experts say, is gulping. .<br />Researchers found the act of gulping water is like a meter for the brain, which promptly deciphers how much fluid is entering the body.<br />The next step occurs in the intestine.<br />The intestine is tasked with transferring water into the bloodstream, .<br />... where cells in the hepatic portal area respond to hormones produced when water dilutes <br />the salt found in the intestine.<br />Researchers say our survival depends on "multiple layers of redundancy and <br />multiple failsafe mechanisms." .<br />When considering our water dependency, experts say the complicated process is to be expected
