Anyone who's had Montezuma's revenge in Mexico knows this truth: water quality matters.
Ancient civilizations understood this. They boiled water, distilled it, or fermented it into beer and wine to kill parasites and bacteria. Modern water treatment plants continue this tradition, but they've added chemicals that solve one problem while creating others.
Your tap water won't give you dysentery. But the treatment process introduces compounds that disrupt thyroid function, compete for essential minerals, and accumulate in your tissues over decades.
Here's what's actually in your drinking water, and what you can do about it.
Most urban and suburban homes connect to municipal water systems. Treatment plants use a multi-step process to make water safe for consumption.
Step 1: Aluminum sulfate for clarification
Aluminum sulfate helps sediment settle out of water, making it clearer. The aluminum residue stays i...
Everyone's carrying a water bottle. But not all water hydrates the same way.
You can drink a gallon of the wrong type and still end up chronically dehydrated, running to the bathroom every hour while your cells stay thirsty.
The difference isn't just purity. It's mineral content, osmolarity, and whether your body can actually hold onto what you're drinking.
Here's how to choose water that actually works.
Your body doesn't just need H₂O molecules. It needs water with the right mineral content and electrical charge to move across cell membranes and stay in your tissues.
Pure water (no minerals) has low osmolarity. It passes through your system quickly because there's nothing holding it in your cells. You drink it, you pee it out, and your intracellular hydration status doesn't change.
Water with minerals has higher osmolarity. The dissolved electrolytes (sodium, magnesium, calcium, potassium) create the osmotic g...
