Self-care is not a spa day—it’s giving your cells what they need under stress (heat, sweat, travel, illness).
Electrolytes = sodium, potassium, magnesium. Here’s why they matter:
✅Fluid balance: Sodium pulls water into the bloodstream (extracellular); potassium holds water inside cells (intracellular). Balanced = less dizziness, steadier energy.
✅Electrical signals: Nerves and muscles fire via sodium-potassium gradients; magnesium helps the channels work → fewer cramps and twitchy fatigue.
✅Better absorption: Sodium (with a touch of glucose) co-transports water in the gut (SGLT1), hydrating more effectively than plain water alone.
✅After sweat/heat/flight: You lose mostly sodium in sweat; dry cabin air and saunas shift fluid fast. Replacing minerals prevents “I drank water but still feel off.”
✅Overhydration check: Clear urine + headache/light-headed after lots of plain water can signal dilution (low sodium), not a water shortage.
When to use:
➠ 60+ min workouts, hot/humid days, sauna, long flights, GI illness recovery.
➠ Desk days/cool weather? Water to thirst is usually enough.
How to use (simple cues):
📌Aim ~300–600 mg sodium per 500 ml on sweaty days; include some potassium (100–300 mg).
📌Sip, don’t chug. Pair sweeter mixes with activity, not all day.
📌Label check: meaningful sodium (not 0 mg), some potassium, modest sugar, serving size sanity.
Safety note: If you’re salt-sensitive or have kidney/heart/blood-pressure conditions, talk to your clinician.
Save this for your next workout or travel day.
