You’re not hydrated, you’re just not thirsty

“Drink more water” is good advice. Until it isn’t.

Most of us don’t drink enough. And even when we do, we’re often sipping water laced with heavy metals, microplastics, and chemical residues.

In trying to remove the bad stuff, we’ve also stripped away essential minerals your body needs to stay hydrated.

So we stay clean… but still functionally dehydrated.

That’s why how you hydrate matters just as much as how much.

What should (and shouldn’t) be in your water

As water moves through the earth, it naturally absorbs beneficial minerals; but it also picks up contaminants along the way.

What belongs: Essential minerals

• 🦴 Calcium: Strengthens bones and supports nerve and muscle function.

• ⚡ Magnesium: Essential for energy, metabolism, and muscle relaxation.

• 🍌 Potassium: Balances body fluids and supports heart function.

• 💧 Sodium: Vital for hydration and nerve signaling.

• 🔬 Trace Minerals (Zinc, Copper, Selenium, Manganese): Boost immune function, antioxidant defenses, and enzyme function.

We used to drink from wild springs.

Mineral-rich. Ice-cold. Unprocessed.

Then came the pipes. The chemicals.

Now?

150 million Americans¹ sip on water laced with PFAS, toxic “forever chemicals” that don’t break down... ever.

What doesn’t belong: Contaminants

• ♾️ PFAS (Forever Chemicals): Persistent chemicals linked to serious health risks² . Primarily enter water via industrial discharge and landfill leakage.

• ⚗️ Disinfection Byproducts (DBPs): Chemical residues from water treatment, some of which act as endocrine disruptors³ and may affect fertility and long-term health.

• 🦷 Excessive Fluoride: Although fluoride may reduce tooth decay at low levels, chronic exposure to levels even below 0.5 ppm may impair thyroid health⁴ . Naturally occurs but often artificially added.

• 🚰 Lead: Typically from outdated pipes, lead contamination remains a significant concern⁵ even in developed regions. There is no safe level of lead exposure, especially for children.

Practical actions for cleaner water

Step 1: Check what’s in your local water supply

Start by Googling your zip code for a local water quality report, or contact the Safe Drinking Water Hotline⁶.

To know what's really in your water, get an independent test. Send your water off for an annual lab test (like this one⁷).

You might find arsenic⁸ in L.A. water or chloroform⁹ in New York City. Maybe even PFAS¹⁰ in Miami or chromium¹¹ (heavy metal) in Austin, often at levels 40x higher than recommended.

Cheap strip water tests are tempting, but they're often sales tools for filter companies—overly sensitive and inaccurate.

Step 2: Choose the right filter

Home water filters can remove harmful contaminants without going off grid. Options range from a $20 countertop unit to a $800+ full setup.

Simple pitcher filters (like the Brita filter¹²) clear chlorine easily but won’t touch fluoride or heavy metals, while advanced countertop¹³ or under-sink systems¹⁴ tackle nearly everything from fluoride to PFAS, though they require more regular upkeep.

Reverse osmosis¹⁵ with UV is the gold standard, zapping microbes and virtually all pollutants, but be prepared for higher costs and more hands-on maintenance.

“Eight glasses a day” isn’t cutting it

The classic rule “six to eight glasses of water a day” isn't precise. Your ideal intake depends on your activity, environment, and body size.

You need to get this right, as even mild dehydration¹⁷ (just 2%) can impair mood, memory, attention, and physical performance¹⁸.

How much to drink:

Your daily water needs depend largely on weight. Use the below formulas:

1. Baseline Intake: Weight (lbs) × 0.5 = ounces/day

2. During Exercise: Weight (lbs) ÷ 30 = ounces every 15-20 mins

3. Hot Environments/Sauna: <8 oz every 15 mins

Or if you don’t feel like mathin’, use this Water Intake Calculator¹⁹.

When to drink:

Drink most of your water early. Your kidneys naturally flush waste in the first half of the day, making morning hydration effective (and you’ll avoid annoying nighttime bathroom trips).

Ease off water 2–3 hours before sleep. If you need to drink before bed, sip slowly.

What about mealtimes?

Strategic timing around meals helps metabolism and digestion:

• Drink 30 mins before meals to aid fullness²⁰.

• Avoid water during carb-heavy meals to reduce blood sugar spikes²¹.

• If drinking during meals, limit to less than 3.3 oz (100 mL) -or better none at all- to maintain optimal digestion.

  

Is “smart” water worth the hype?

Trendy waters aren't magic.

Alkaline water's benefits mostly come from added minerals rather than pH, and distilled or reverse osmosis waters, while pure, strip out essential minerals.

Hard water is mineral-rich and heart-healthy, but tough on plumbing and terrible for your hair and skin, while hydrogen-enriched water does show early promise for hydration and inflammation, though more research is needed²² .

Your best bet? Filtered water with plenty of electrolytes like sodium, potassium, and especially magnesium.

These minerals don't just hydrate, they power nerve function, muscle performance, and stable blood pressure.

If you’re fasting, keto, or sweating heavily, adding electrolytes (via natural salts or electrolyte powders²³) ensures your water truly hydrates.

Bottom line? Every drop counts.

Drink smarter, hydrate better, and give your body the clean, balanced water it deserves. Because the fountain of youth might just be your faucet.

🚰 Final Takeaway: Hydration Checklist

☑️ Check Your Water Quality (Use Google and test kit / lab report)
☑️ Get a Suitable Water Filter (Pitcher, countertop, under-sink)
☑️ Daily Intake: Calculate based on your weight, then 8 oz/hour for first 10 hours
☑️ Evenings: Limit to 5–8 oz to improve sleep
☑️ During Exercise: Body weight (lbs) ÷ 30 oz per 15–20 min
☑️ Meals: Drink water 30 mins before or after (not during)
☑️ Hot Weather/Sauna: Add 50–100% more fluids
☑️ Aim for Mineral-rich Water with a neutral to slightly alkaline pH
☑️ Add Electrolytes (sea salt or electrolyte supplements, especially if fasting or exercising)
