  1. Strange but True: Drinking Too Much Water Can Kill

  2. Strange but True: Drinking Too Much Water Can Kill Drinking enough water is essential for the human body to function, but drinking too much can be just as dangerous as drinking too little. A panel of 17 experts from around the world collaboratively wrote guidelines outlining the safest way to drink water without going overboard.

  3. Why too much of water is bad for your health • In humans the kidneys control the amount of water, salts and other solutes leaving the body by sieving blood through their millions of twisted tubules. When a person drinks too much water in a short period of time, the kidneys cannot flush it out fast enough and the blood becomes waterlogged. Drawn to regions where the concentration of salt and other dissolved substances is higher, excess water leaves the blood and ultimately enters the cells, which swell like balloons to accommodate it.

  4. There are many tragic examples of death by water. • In 2005 a fraternity hazing at California State University, Chico, left a 21-year-old man dead after he was forced to drink excessive amounts of water between rounds of push-ups in a cold basement. • Club-goers taking MDMA ("ecstasy") have died after consuming copious amounts of water trying to rehydrate following long nights of dancing and sweating.

  5. A 2005 study in the New England Journal of Medicine • A 2005 study in the New England Journal of Medicine found that close to one sixth of marathon runners develop some degree of hyponatremia, or dilution of the blood caused by drinking too much water.

  6. 3 reasons why drinking too much water is bad for you • Consuming too much water hinders your body's ability to get rid of waste • Excessive water negatively affects the brain • It wears out your circulatory system

  7. Consuming too much water hinders your body's ability to get rid of waste • Your kidneys' function is to sift excess waste and water out of the bloodstream, but when you drink too much water, there is a lot more blood for your kidneys to clean. • "If you drink too much water too quickly, the blood becomes diluted and the kidneys cannot filter it fast enough to maintain the proper sodium balance,"

  8. 2. Excessive water negatively affects the brain • While studies show water can help memory and focus, they also show that too much water can have the opposite effect. We already know that too much water dilutes your blood. But when your kidneys are unable to get rid of the excess water, the cells in your body swell and take in more and more water to relieve the burden on the kidneys.

  9. 3. It wears out your circulatory system When you drink too much water your body expands to accommodate all the water it doesn't need and can't process, and, much like clothes that don't fit get stretched and worn out quicker, the blood vessel walls wear out from taking on the excess fluid.It also dilutes the amount of sodium in your blood, which your whole body needs in order to function.
