Why are electrolytes good for you?

We see you. Googling are electrolytes good for you??? with three tabs open, trying to figure out whether these mineral-infused hydration products are… well… (pardon the pun) worth their salt. If you’re someone with even a top-line interest in wellness, it can feel like every second Instagram story you click on is claiming that this is the supplement that’s going to change the game. It’s hard to separate hype from genuine insight. In this article, we’re going to do what we do best here at Sodii — consult the science of salt to show you exactly why electrolytes are good for you. Ready to tear into it? The research, that is. And maybe a sachet of hydration salt or two!

First Things First… What Are Electrolytes?

Electrolytes are minerals like sodium, potassium, magnesium, calcium, and chloride that dissolve in your body fluids and carry an electric charge. 

Think of electrolytes like the pacers in your run club; they each have a role to keep things moving.

  • Sodium sets the pace for hydration.

  • Potassium keeps your muscle rhythm in check.

  • Magnesium is the calm captain, preventing cramps.

  • Calcium triggers each muscle contraction, powering every step.

  • Chloride balances the pack, keeping fluids and pH steady.

Take one out, and the whole rhythm’s off. Keep the crew together, and you're running like a well-oiled machine.

Now, Down to Business… Why Are Electrolytes Good For You?

So, why are electrolytes good for you? Basically, they help your body function at its best. They dissolve in your body fluids (like blood, sweat, and urine) and carry tiny electrical charges that your cells use to communicate and perform vital tasks.

These charged particles help regulate how much water stays inside or outside your cells (hello, hydration), control your muscle contractions (including your heart), transmit nerve signals (so your brain and body communicate), and keep your blood pH balanced.

If you’ve only reached for them once or twice, it was probably when you were sick — right? Maybe a sports drink after a bout of gastro, or that mysterious fruity beverage your mum gave you when you couldn’t keep food down.

But here’s the thing: electrolytes aren’t just for emergencies. You lose them every time you sweat, train, or even go too long between meals. And when your levels are off, your body feels it — fatigue, headaches, cramps, brain fog, or worse (like heart rhythm issues or seizures in serious cases). Water alone won’t fix it. You need the right mix of minerals to properly rehydrate and recover. 

Are Salt Electrolytes Good For You Every Day?

Short answer? Yes. You lose electrolytes every single day, not just when you're sweating buckets.

Wondering why salt is so essential for humans? It:

Despite what you may have heard, sodium isn’t the villain. In fact, having low sodium can be pretty problematic—it can cause dehydration, brain fog, high heart rate, and a general feeling of… well… blah.

You might even be losing sodium without realising it.

Caffeine, intense workouts, medications, low-salt diets, or even chugging lots of plain water can all dilute or deplete your sodium stores. That’s where replenishment comes in.

Sodii’s Everyday Hydration Salts give you 1000mg of sodium (from 2000mg of salt) plus potassium and magnesium—for hydration that actually works, not just water in, water out. More on that later!

Other Helpful Applications of Electrolytes

You know they’re great for hydration—but that’s just the start. From bouncing back after a bug to powering through a workout (or a workday), here’s how electrolytes can support you in more ways than you think:

Why Electrolytes Are Good for You When You’re Sick

The vomiting, diarrhoea and fever that come from gastro, and even just a run-of-the-mill cold, can deplete your body of vital fluids and minerals fast. That fuzzy-headed, weak-limbed feeling? Often, it's not just the illness, but the electrolyte imbalance that comes with it. 

Replenishing sodium, potassium, and magnesium can help restore hydration, support immune function, and give you the strength to get back on your feet sooner. A full system reboot for your body, if you will, just without the dreaded blue screen of death!

Why Electrolytes Are Good for You in the Morning 

After 6–8 hours of sleep (and zero water), your body wakes up a little bit dehydrated. Add in coffee (a diuretic), maybe a sweaty morning workout, or even just a hectic start to the day—and you're already in the red. Starting your morning with a balanced dose of electrolytes helps kickstart hydration, support energy production, and give your nervous system a proper wake-up call. Better than a double espresso? We’ll let you decide.

Why Electrolytes Are Good for You After a Workout

Exercise = sweat. Sweat = fluid and mineral loss. When you finish a workout, you’re not just low on water—you’re likely low on sodium, potassium, magnesium, and chloride too. Rehydrating with a science-backed electrolyte mix post-exercise helps your body recover faster, prevent cramps, maintain blood pressure, and reduce fatigue. So if you’ve been wondering why water alone isn’t cutting it after a big session… you’re welcome!

Are Electrolytes Good for You When Pregnant?

While we’re not handing out medical advice, we can say that pregnancy can throw your hydration needs into overdrive.

Nausea, vomiting, increased fluid volume, and even just growing a tiny human in your body can all impact electrolyte levels. 

Upon consultation with your doctor, supplementing with balanced electrolytes like Sodii may help support your pregnancy hydration needs.

TLDR: How Are Electrolytes Good for You?

Because they help your body function—properly, efficiently, and consistently. They support:

  • Hydration at a cellular level

  • Muscle function (hi, strength and zero cramps)

  • Nerve signalling (so your brain can actually focus)

  • Thermoregulation (aka sweat that works)

  • Recovery (from workouts, illness, or just life)

And whether you’re sick, sweaty, or just trying to stay sharp from the moment you wake up, electrolytes are a simple, effective way to support daily performance.

Don’t Just Drink Water—Drink Smarter.

If you’re relying on water alone to hydrate, you're missing half the equation.Your body runs on balance; electrolytes are the missing link between feeling flat and firing on all cylinders.

That’s why we created Sodii Everyday Hydration Salts. They’re packed with some seriously good stuff:

  • 1000mg sodium (from Western Australian Lake Deborah salt)

  • 210mg potassium

  • 70mg magnesium

  • Zero sugar, no unnecessary nasties—just hydration that actually works

Hydration that hits. Science you can sip. Grab your first box of Sodii and feel the difference.
