Hydration, made simple
The Water Boi is a small, independent website about everyday hydration: how much fluid people generally need, signs of dehydration, the differences between tap, spring, mineral, distilled and alkaline water, and practical habits that make drinking enough easier.
We don’t sell water, filters or supplements, and we can’t tell you your personal fluid needs. Educational information only, not medical advice; consult a qualified professional.

Types of Drinking Water
Not all water is created equal. Compare your options.
Spring Water
Natural SourceSourced from natural underground springs. Contains naturally occurring minerals like calcium and magnesium. pH typically 6.5-8.5.
- Natural minerals
- Good taste profile
- Variable quality
Distilled Water
PurifiedBoiled to steam then condensed back. Removes virtually all contaminants and minerals. pH around 7.0 but can drop to 5.8 when exposed to air.
- Contaminant-free
- No beneficial minerals
- Flat taste
Alkaline Water
pH 8-9+Higher pH than regular water. Proponents claim it neutralizes acid, though scientific evidence is mixed. Often enhanced with electrolytes.
- Higher pH level
- Added electrolytes
- Limited proven benefits
Mineral Water
Naturally EnrichedContains at least 250 ppm TDS from a geologically protected source. Rich in calcium, magnesium, potassium, and sometimes sodium.
- High mineral content
- Consistent quality
- Can be expensive
Tap Water
Municipal SupplyRegulated by EPA with mandatory testing. Quality varies by location. Often treated with chlorine/fluoride. Most accessible and affordable option.
- Inexpensive
- EPA regulated
- Chlorine taste
Reverse Osmosis
FilteredPushed through a semipermeable membrane removing 95-99% of contaminants. Often remineralized after filtering. Excellent for home use.
- Near-pure water
- Removes most contaminants
- Wastes water in process

Hydration Pro Tips
Practical habits that make staying hydrated easier
Educational information only, not medical advice; consult a qualified professional. Fluid needs vary with health conditions (for example kidney or heart disease) and medications — follow your clinician’s advice. Severe dehydration is a medical emergency.
