Water doesn’t expire like milk or yogurt. It’s not a dramatic, smelly rot. It’s a slow, quiet quality fade, mostly due to the plastic it lives in. So treat your water like you treat your leftovers: respect the container, watch the temperature, and when in doubt, refresh.
If you want the ultimate life hack, buy a reusable glass or stainless steel bottle. Fill it with tap water every morning. It costs pennies, it’s better for the planet, and you’ll never have to wonder if your drink has a secret expiration date again. Now go hydrate—with something that hasn’t been sitting in your car since the Fourth of July.
