  • There's a time in every person's life when drinking water is deadly.


  • Even as much as a few ounces is enough to kill.


  • The average healthy adult is made up of 55 to 60% water.


  • The average baby, on the other hand, is roughly 75% water.


  • And that difference is why babies shouldn't drink water before they're at least six months old.


  • Not from the tap or a well or a spring.


  • Plain water is just plain off limits.


  • You see, everyone's kidneys have a limit to how much water they can handle.


  • Break that limit, and the excess water will back up into your bloodstream, where it dilutes the salt, or sodium, in your blood.

    その制限を破ると、余分な水が血流に逆戻りします。 それはあなたの血の塩、またはナトリウムを希釈します。

  • Once your blood dips below 0.4 ounces of sodium per gallon, you're at risk of a condition called Hyponatremia.


  • It happens when your cells try to return sodium levels to normal by absorbing the extra water and swell up like a water balloon in the process,

    それはあなたの細胞がナトリウムのレベルを戻そうとするときに起こります。余分な水を吸収して正常に と、その過程で水風船のように膨らみます。

  • causing complications like confusion, vomiting and muscle spasms.


  • Hyponatremia is common in marathon runners who drink too much too fast during a race without also providing enough sodium to balance out their blood.

    マラソンランナーに多い低ナトリウム血症レース中の飲み過ぎ 十分なナトリウムを提供することなく 血のバランスを整えるために

  • And if you keep drinking, that excess water will eventually reach the cells in your brain.


  • By this point, you have a dangerous case of water intoxication, which affects roughly 200,000 Americans each year.

    この時点で、あなたは危険なケースを持っています。水中毒になると 毎年約20万人のアメリカ人が

  • It occurs when your brain cells swell, which builds up pressure inside your skull that can lead to seizures, brain damage, and, in severe cases, death.

    脳細胞が腫れることで起こります。頭蓋骨の中に圧力がかかる 発作や脳障害を引き起こす可能性があります。 重度の場合は死に至ることもあります。

  • But don't worry, dying from water intoxication is extremely hard for a fully-grown human.


  • An adult would have to drink 2.5 to 5 gallons every few hours to reach that point.


  • But for newborns, it's a different story.


  • Their kidneys are about half the size of an adult's, so they can't hold much water to begin with.


  • And it takes just a few ounces to cause problems.


  • On top of that, their kidneys aren't developed enough yet to properly filter water, so any water that enters their body ends up in the circulatory system,

    それに加えて、腎臓がまだ十分に発達していない。水を適切にろ過するために、どのような水でも 彼らの体に入ると、循環系で終わります。

  • where it dilutes their blood and increases their water content by 7 to 8%.


  • But it's not just drinking straight H2O that poses a threat.


  • In fact, most cases of water intoxication in infants don't even involve a glass of water.


  • A common mistake is when people dilute baby formula too much by accident, or when parents dunk their infants up and down in a swimming pool,

    よくある間違いは、赤ちゃんの粉ミルクを薄めてしまうことです。うっかりしすぎたり、親が 幼児をプールに上下に沈めます。

  • and in the process the infant gulps in too much water.


  • It's important that if your baby is showing signs of water intoxication that you take them to the hospital immediately,

    重要なのは、赤ちゃんが酔いが回っている すぐに病院に連れて行って

  • where a doctor will likely provide some form of fluids like intravenous saline solution to bring the infant's sodium levels up to normal.

    水分補給の場生理食塩水のような 幼児のナトリウムのレベルを正常に持って来るために。

There's a time in every person's life when drinking water is deadly.
