How Much Water Drinking per Dayの主要なニュースを専門的かつ分かりやすくまとめました。全体像を一目で把握できます。

Forget the eight-glass rule. Instead, follow the “pee check and don’t be a jerk to your kidneys” method. Keep a bottle nearby, sip when you feel like it, and if you’re ever in doubt, drink enough so that you don’t get a headache. But also, if you’re drinking water and you start to feel emotionally superior to others—like you’re the hydration pope—please stop. Over-hydration and sanctimony are a terrible combo. In short: drink like a sensible human, not a camel auditioning for a drought. Your body knows what it’s doing; let it have the last word. And if you’re still worried, just eat a cucumber. It’s basically water with a superiority complex.
