By Sebastian Madlangbayan, founder of Cleonse: the world's cleanest 3-ingredient organic electrolyte.
The best electrolytes for hot yoga give you meaningful sodium to replace what you sweat out in a heated room, a little carbohydrate to steady your energy, and clean ingredients that won't upset your stomach mid-flow. Sodium is the one that matters most here, because you lose a lot of it fast when you're sweating for an hour at 95 to 105 degrees.
I'm Sebastian Madlangbayan. I played tennis at a state-champion level, which means I've spent a lot of hours sweating hard and learning the hard way what happens when I don't replace what I lose. I built Cleonse because I wanted something honest and simple to drink around training. Hot yoga isn't tennis, but the hydration problem is close enough that I get asked about it a lot. So here's my straight take.
Why hot yoga hits your hydration differently
A heated studio is usually somewhere between 95 and 105 degrees, sometimes humid on top of that. You're moving continuously for 60 to 90 minutes. Your body's only real way to cool itself is sweat, so it turns the tap on and leaves it running the whole class.
Here's the part people miss: sweat isn't just water. It carries sodium out with it. In a normal room-temperature workout you might not notice the loss much. In a hot room, you're sweating heavily for a long stretch, and the sodium adds up in a short window. That's the specific challenge hot yoga creates. It's not that you sweat more than any other exercise on earth, it's that you sweat a lot, concentrated into one heated hour, often first thing in the morning before you've eaten or drunk much.
Why water alone can leave you lightheaded
The instinct after a hot class is to chug plain water. It makes sense, you're thirsty. But if you've sweated out a real amount of sodium and you only put back water, you're diluting what's left. That mismatch is part of why some people feel dizzy, foggy, or oddly wiped out after class instead of refreshed.
Water is doing its job. It just doesn't carry the sodium you lost. To actually hold onto the fluid you drink and feel steady afterward, you need to replace some of that sodium too. That's the whole reason electrolyte mixes exist.
When to hydrate around a hot class
My general approach is front-load and back-fill. Come in already hydrated, and replace properly afterward. What you do during class is more personal than people admit.
Before
Don't walk in dry. Drinking your fluids and electrolytes 30 to 60 minutes before class means you start the session topped off instead of playing catch-up the whole time. This is the single easiest thing to get right, and it's the one most people skip.
During
Sipping during class is a personal call. Some people feel great taking small sips of water between poses. Others find anything in their stomach makes inversions and twists uncomfortable. There's no rule here. If you sip, keep it to water and keep it small. Save the real electrolyte replacement for after, when your stomach is settled and you're not upside down.
After
This is where electrolytes earn their place. You've just spent an hour losing sodium and fluid. Replacing both together, within a reasonable window after class, is what helps you actually feel like yourself again rather than dragging for the rest of the morning. Supports hydration is the honest way to say it, and it's the after-class drink that does the most work.
A simple hot-yoga hydration plan
Here's how I'd lay it out. Adjust to your own body, your class length, and how much of a sweater you are.
| When | What to do | Why |
|---|---|---|
| 30-60 min before | Drink 16 oz water with electrolytes | Start the class topped off, not playing catch-up |
| During class | Small sips of plain water if it feels right (optional, personal) | Comfort varies; no need to force fluids while inverting or twisting |
| Right after | Replace fluid and sodium together | You've lost a lot of both; water alone can leave you lightheaded |
| Rest of the day | Keep drinking to thirst | Recovery continues after you leave the studio |
What to look for in a hot-yoga electrolyte
Not all electrolyte mixes are built for this. A few things I'd actually check:
Meaningful sodium
Sodium is the electrolyte you lose most in sweat, so it's the number that matters most for hot yoga. A pinch is not enough after a heated class. You want a mix that puts back a real amount, not a trace for flavor.
Some carbohydrate for steady energy
A little real carbohydrate does two things. It gives you light, steady energy, and glucose actually helps your body drive sodium and water absorption. That's not marketing, it's the basic mechanism behind how your gut takes fluid in. A small amount of real sugar can make an electrolyte drink work better, not worse.
Clean ingredients so your stomach behaves
Twisting and folding in a hot room is not the time to find out a drink disagrees with you. Artificial sweeteners, sugar alcohols, gums, and fillers are common culprits for that heavy or uneasy stomach feeling. Fewer ingredients you recognize means fewer surprises. If you want to go deeper on this, I wrote about what the cleanest electrolyte actually means.
The over-hydration trap: don't just drown yourself in water
There's a real risk on the other side of dehydration that gets talked about far less. When you sweat heavily and then drink large amounts of plain water without replacing sodium, you can dilute the sodium in your body too far. That's called hyponatremia, and it's the actual reason sodium replacement matters when you're a heavy sweater.
I'm not saying this to scare anyone. For most people in a normal hot yoga class it's not a daily concern. But it's exactly why the answer to heavy sweating is not just more water. It's water plus the sodium you lost. If you're the type who sweats through your mat and then downs a liter of plain water afterward, that's the pattern worth adjusting. This is general education, not medical advice, and if you have any health condition that affects your fluids or sodium, talk to your doctor.
Where Cleonse fits
I'll be straightforward about what Cleonse is and isn't, because honesty is the whole point of how I built it.
Cleonse electrolyte drink mix has exactly three ingredients: organic lemon or organic strawberry powder, organic cane sugar, and French grey sea salt. That's it. No stevia, no artificial sweeteners, no artificial flavors, no dyes, no preservatives, no gums, no fillers, no anti-caking agents. It's vegan and gluten-free.
Each stick gives you 500mg of sodium, which is a meaningful amount to put back what you sweat out in a hot room, not a token pinch. The French grey sea salt also brings 85-plus trace minerals, in genuinely trace amounts, so I'm not going to pretend it's dosing you with anything. The organic cane sugar is intentional. It's 24g of sugar and 100 calories per stick, real training fuel, and the glucose helps your body pull that sodium and water in. You mix one stick into 16 oz (473 ml) of water.
For hot yoga, that lines up cleanly: real sodium to replace what you lose, a little real fuel for steady energy, and a short, clean ingredient list so your stomach isn't fighting you. You can read the full Cleonse facts if you want every number in one place.
Where Cleonse is honestly not your best pick
I'm not going to tell you Cleonse is right for everyone, because it isn't. Two honest concessions:
If your class is gentle, short, or you're just a light sweater, plain water might genuinely be all you need. You don't have to add anything to feel fine. Listen to your own body.
And if you specifically want zero sugar and zero calories, Cleonse is not for you. It has 24g of real sugar per stick on purpose, because I think the sugar helps the drink do its job as training fuel. If you're avoiding sugar and calories entirely, there are sugar-free electrolyte mixes made for exactly that preference. That's a real fork in the road, and I'd rather you pick the right thing than the thing I sell.
My honest bottom line
If you sweat hard in a heated room, replacing sodium is the move, and doing it with clean ingredients and a touch of real fuel is how I'd do it. That's the whole reason Cleonse exists in three ingredients instead of thirty. If that sounds like what you've been missing after class, you can try it at cleonse.com. It comes in Organic Lemonade, Organic Strawberry, and a Duo Assortment, with free shipping and a 30-day guarantee, so it's a low-risk thing to test against your own body.

Shop CleonseFrequently Asked Questions
Do I really need electrolytes for hot yoga, or is water enough?
It depends on how much you sweat. For a gentle or short class, or if you're a light sweater, water may be all you need. But in a heated room where you're sweating heavily for an hour, you're losing real sodium, and replacing that alongside water is what helps you feel steady afterward rather than lightheaded.
Should I drink electrolytes before or after hot yoga?
I'd do both if you sweat a lot: come in already hydrated by drinking 30 to 60 minutes before, and replace fluid and sodium together after class. Sipping during class is a personal call, since some people feel fine with small sips of water and others don't want anything in their stomach while inverting.
Can drinking too much water after hot yoga be a problem?
It can. If you sweat out a lot of sodium and then drink large amounts of plain water without replacing any sodium, you can dilute your body's sodium too far, which is called hyponatremia. That's the reason sodium replacement matters for heavy sweaters. This is general information, not medical advice.
Why does Cleonse have sugar in it?
The organic cane sugar is intentional. It gives you light, steady training fuel, and the glucose helps your body absorb sodium and water. Each stick has 24g of sugar and 100 calories. If you specifically want zero sugar or zero calories, Cleonse isn't the right pick and a sugar-free mix would suit you better.
How much sodium is in one Cleonse stick?
500mg of sodium per 30g stick, mixed into 16 oz (473 ml) of water. That's a meaningful amount to replace what you sweat out in a hot class. Cleonse does not add potassium or magnesium, so I want to be upfront that sodium is the electrolyte it focuses on.
What are the ingredients in Cleonse?
Exactly three: organic lemon or organic strawberry powder, organic cane sugar, and French grey sea salt. No stevia, artificial sweeteners, artificial flavors, dyes, preservatives, gums, fillers, or anti-caking agents. It's vegan and gluten-free.
Editor's note: This article is educational and not medical advice. Individual hydration needs vary with class intensity, climate, how much you sweat, and your own health. Hyponatremia, the over-dilution of sodium from drinking large amounts of plain water while sweating heavily, is why replacing sodium matters when you sweat a lot. Cleonse supports hydration and is not a medical product; if you have a health condition, talk to your doctor.
