I have tried multiple hydration approaches for endurance training, daily activity, and recovery. Here’s when each actually matters.
Daily Hydration
For sedentary or moderately active adults: plain water is fine. The 8 cups recommendation is rough - personal needs vary by climate, activity, and individual physiology.
Daily hydration enhancers worth using:
- Sparkling water for variety (LaCroix, San Pellegrino) - same hydration as flat water
- Citrus slices in water for flavor
- Herbal teas (caffeine-free) - hydrating
- Coffee and black/green tea - net hydrating despite mild diuretic effect
Daily hydration claims to ignore:
- “Alkaline water” health benefits (no scientific support)
- “Structured water” (pseudoscience)
- Premium spring water vs tap (mostly marketing)
- Vitamin-enhanced waters (whole food provides better nutrient absorption)
Exercise Hydration
Under 60 minutes moderate exercise: Water sufficient. Don’t over-engineer.
60-90 minutes moderate-intense: Light electrolyte replacement helps. Sweat contains sodium that prolonged sweating depletes.
90+ minutes or hot weather: Sports drink with electrolytes plus carbs is the right approach.
Heavy sweat / endurance events: Specific endurance formulas (Skratch Labs, Tailwind) optimized for prolonged use.
Electrolyte Mixes
LMNT Recharge ( for 30 packets): 1,000 mg sodium per packet, no sugar. For keto, low-carb, heavy sweat, hangover recovery. Premium pricing.
Liquid IV ( for 16 packets): Marketed for hydration multiplier effect. Some sugar (11g). Tastes good. The science behind “hydration multiplier” is overstated but tastes good and works adequately.
DripDrop ORS ( for 16 packets): Medical-grade Oral Rehydration Solution formula. For severe dehydration, illness recovery. Less appealing taste than competitors.
Skratch Labs Hydration ( for 20 servings): Athletic-focused formula. Less sodium than LMNT, more carbs. For active endurance use.
Pedialyte: Pediatric ORS formula. Excellent for stomach illness recovery, also adequate for general hydration. Less expensive than premium brands at standard pharmacies.
Sports Drinks
Gatorade: The classic. 14g sugar, 160mg sodium per 12 oz. Adequate for typical exercise. Marketing-driven flavor variety.
Powerade: Similar to Gatorade. Slightly different electrolyte profile. Comparable performance.
BodyArmor: Higher sodium (15mg/oz), uses coconut water as base. Slightly better hydration profile than Gatorade.
Propel Zero: Sugar-free sports drink. Artificial sweeteners replace sugar. For users wanting electrolytes without calories.
For most users: Gatorade or BodyArmor work fine for serious exercise.
Coconut Water
Pros: Natural source of potassium and electrolytes. Lower sugar than sports drinks. Adequate for moderate hydration needs.
Cons: Lower sodium than sports drinks (less effective for heavy sweat). Premium price for water-based drink. Plain coconut water taste isn’t universally appealing.
Best uses: Post-workout for light exercise. Hot weather casual hydration. Hangover recovery (with some additional sodium).
Brands: Vita Coco, Harmless Harvest, ZICO. All adequate.
Milk-Based Hydration
Chocolate milk: Studies show effective post-workout recovery drink. Carb-to-protein ratio matches sports recommendations. Replaces fluid plus protein.
Whole milk: Better hydration than equivalent water (slow gastric emptying). Some athletes use post-exercise.
Caveat: Lactose intolerance prevents many users. Lactose-free milk alternatives work.
Specific Use Cases
Hangover recovery: Electrolyte mix (LMNT, Pedialyte) + water. Sugar (orange juice, banana) for blood sugar.
Stomach flu / vomiting: ORS solutions (DripDrop, Pedialyte). Don’t add to vomiting with strong flavors initially.
Hot weather work: Sports drink for heavy sweat. Plain water plus snacks for moderate sweat.
Long flights: Plain water best. Avoid alcohol and excessive caffeine. Some saltines or salted snacks help.
Marathon training: Skratch Labs or Tailwind during runs over 90 min. Plain water for shorter runs.
Daily life: Plain water plus coffee/tea. Skip the marketed hydration drinks.
Common Mistakes
Over-hydrating with sports drinks: Sugar and calories add up. For sedentary days, plain water is correct.
Skipping electrolytes during intense activity: Cramping and fatigue often result from electrolyte loss not water shortage.
Trusting “hydration claims”: Most enhanced waters and functional beverages have minimal advantage over plain water.
Drinking too fast during exercise: Causes stomach discomfort. Steady intake of 6-8 oz every 15-20 minutes during activity.
Confusing thirst with hunger: Body sometimes signals dehydration as hunger. Try water first when hungry between meals.
My Personal Approach
Daily: Plain water + 2-3 cups coffee.
Workouts under 60 min: Plain water only.
Workouts 60-90 min: LMNT Recharge in water bottle for electrolytes.
Long runs (90+ min): Sports drink (Gatorade) every 30 minutes.
Hot weather days: Add an LMNT packet to morning water. Plain water rest of day.
Hangover: LMNT + plain water + banana for sugar.
Total cost: on premium electrolyte mixes (LMNT). Plain water otherwise.
When to Drink What
Water plus electrolytes: heavy exercise, hot weather, recovery from illness, hangover.
Plain water: most daily situations, mild exercise, hydration with meals.
Sports drinks: endurance exercise, prolonged outdoor work.
Functional drinks: rarely useful - usually marketing.
Cost Comparison
Per serving:
- Tap water:
- Bottled water:
- Sports drink:
- Coconut water:
- Electrolyte mix (LMNT):
- Pedialyte:
For daily use, the cost difference matters over months and years. Save the premium drinks for when they actually matter.
Frequently asked questions
Do I need sports drinks?+
For under 60 min exercise, water is fine. For 60-90 min moderate intensity, electrolytes help. For 90+ min or hot weather, sports drinks with carbs and electrolytes are useful. Daily life rarely needs anything beyond water.
Coconut water vs sports drinks?+
Coconut water: natural, lower sugar, less sodium. Sports drinks (Gatorade): more sodium, optimized for sweat replacement, higher carbs. For mild activity, coconut water. For intense training, sports drinks.
Best electrolyte mixes?+
LMNT (high sodium, low sugar) for keto or intense sweat. Liquid IV (premium hydration claims, more sugar). Skratch (athletic optimization). DripDrop (medical ORS formula). Match to use case.
Are functional waters worth it?+
Most 'functional water' (Vitamin Water, Smartwater) is marketing. Added vitamins are easier from whole food. Electrolyte waters genuinely useful only when sweating heavily.
Coffee and tea count?+
Yes - mild diuretic effect is offset by water content. Coffee/tea net-positive for hydration. The 'coffee dehydrates' claim is outdated. But alcohol genuinely dehydrates - drink water alongside.
