Hey friends, it's Lizzie! Training through Florida summers taught me this the hard way: water alone isn't enough when you're really sweating. If you finish workouts foggy, crampy, or wiped out, you probably need electrolytes — here's what to look for.
Why electrolytes matter
When you sweat, you lose more than water — you lose sodium, potassium, and magnesium, the minerals that keep your muscles firing and your energy steady. Chugging plain water after a hot session can actually dilute what's left, which is why you can drink a ton and still feel awful. Electrolytes put back what you sweat out.
What to look for
- Real sodium (the one you lose most) — don't fear it around exercise.
- Potassium + magnesium for cramps and recovery.
- Low or no sugar — you want hydration, not a soda.
- A taste you'll actually drink — the best one is the one you'll use.
Signs you're actually dehydrated
Your body will tell you — you just have to know the signals. Watch for a nagging headache, muscle cramps, dizziness when you stand, dark-yellow pee, or that wiped-out, foggy feeling after a sweaty session even though you drank water. Those are all signs you're losing more than you're replacing.
DIY vs. a ready-made mix
In a pinch, you can DIY electrolytes with a pinch of quality salt, a squeeze of citrus, and a tiny bit of honey in water — it works. But honestly? The reason I use a ready-made mix like Cure is that it's convenient and tastes good enough that I'll actually reach for it, with the right minerals already balanced. The best hydration strategy is the one you'll genuinely stick to, especially when it's 95 degrees and you'd rather do anything than measure salt. Keep it simple, keep it consistent. 💧
How I actually mix mine
Real talk, the mix matters more than people expect. I keep a box of Cure packets in my gym bag and a couple in the car, because the whole point is having it ready before I’m already wiped, not scrambling for it after. My routine is simple. Cold water, always. It goes down so much easier icy than room temp, especially after a sweaty round. I tear a packet into a full water bottle, cap it, and give it a hard shake for a few seconds so nothing settles at the bottom. If I’m home, I’ll pour it over ice and sip it slow instead of chugging.
Two things I’ve learned the hard way: don’t dump it into warm water and expect to love it, and don’t let it sit half-dissolved. Shake first, sip second. Cure is my pick because the flavor stays light instead of syrupy, so I actually want to finish the whole bottle (code LILO at checkout, and I broke down the flavors in my Cure review). If you’re new to electrolyte mixes, start with a citrus flavor you already know you like, because a taste you dread is a taste you’ll skip.
The Florida-humidity curveball
Here’s the thing nobody warns you about with humid heat: you can be drenched and still not clock how hard you’re going, because the air is so thick the sweat just sits on you. Training through a Space Coast July taught me not to wait until I feel rough. I fill my bottle before a session, not after, so it’s cold and waiting the second I’m done.
A few logistics that genuinely make hot-weather training easier:
- Move your workout early or late. Midday humidity here is no joke, and shifting to sunrise or after 6pm changes the whole session.
- Keep a bottle in the freezer. A slushy-cold mix in this heat is a tiny luxury that keeps me actually drinking it.
- Stash single packets everywhere. Gym bag, beach tote, carry-on. They’re flat and travel-proof, so I’m never stuck.
That last one is the real move if you’re headed somewhere hot this summer. Toss a handful of packets in your bag and your routine travels with you, wherever you land.

When you actually need them
You don't need electrolytes with every glass of water — but do reach for them after a sweaty workout, on hot days, when you're active outside, or the morning after a late night. If it's a light, low-sweat day, plain water is fine. Listen to your body and top up when you've earned it. 💧🌴
Quick questions
When do I actually need electrolytes? After sweaty or hot workouts, when you're active outside, or the morning after a late night. On low-sweat days, water is fine.
Can you have too many electrolytes? You don't need them with every glass of water — balance them with plain water and use them when you've genuinely sweated.
What makes a good electrolyte mix? Real sodium plus potassium and magnesium, with little to no added sugar, and a flavor you'll actually drink.
If that sounds like you: the best electrolytes for runners.
