Is It Ok to Drink Water from the Hot Tapの注目されている理由をコンパクトにまとめました。全体像を一目で把握できます。

Here’s a fun fact: your hot water heater is set to 120–140°F (50–60°C). That’s not hot enough to kill most bacteria. But it is warm enough to make them feel cozy.

So if the water sits in the tank for a while, you might be sipping a lukewarm bacterial spa. Refreshing? No. Disgusting? Yes.

“But I Boil It After!”

Good thinking! But if you’re boiling hot tap water, you’re still concentrating the metals that already dissolved. Boiling doesn’t remove lead or copper—it just makes them more concentrated.

So you’re not making safe water. You’re making metal-broth with extra steps. Pass.
