Why Your Water Bottle Isn't Enough For The Sauna
What I learned after 18 months of dizziness, headaches, and leg cramps from using the sauna. And the 30-second fix that ended all of them.

Everyone quotes the stat. Nobody finishes the sentence.
You have seen the number. In a long-running Finnish study, men who used the sauna 4 to 7 times a week had roughly 50 percent lower cardiovascular mortality than once-a-week users (Laukkanen, 2018). That one finding built the modern sauna boom.
Here is the catch. The people actually chasing that benefit, the 4x a week crowd, are the same people filling sauna forums with an identical complaint.
They wake up feeling like they got hit by a bus.
- Calf and hamstring cramps that lock up for ten minutes straight
- Leg cramps that hit hours later, right as you try to fall asleep
- Mornings after a session that feel like mornings after drinking
- Brain fog and a crash the next afternoon that coffee does not touch
There is a name for it. The sauna hangover.
And it is not the heat that causes it. It is what the heat takes out of you.
One session. One liter. 1,000mg gone.
A 30 minute session at 175°F pulls about 1 liter of fluid out of you. That is basic sweat physiology, not a marketing claim.
And that liter is not just water. It carries minerals out with it. Here is what sweat strips in a typical session:
1,000mg
Sodium stripped
Typical 30-min session
400mg
Potassium stripped
Typical range 300-500
100mg
Magnesium stripped
Typical range 80-120
1,000mg of sodium is roughly half a day's intake. Gone in one sit.
Now look at what most people drink to put it back:
What you drink
Sodium
16 oz plain water
0mg
Gatorade (20 oz)
270mg
Liquid I.V. (16 oz)
510mg
Coconut water (16 oz)
252mg
Sauna Method (1 scoop)
1,000mg

The advice that backfires
When you sweat, you lose water and sodium together. When you chug plain water after, you replace only one of them.
That extra water dilutes the sodium still in your blood. Your sodium concentration drops further than if you had drunk nothing at all.
The mechanism
Plain water replaces volume but not minerals. Your blood gets more dilute, not less.
Half of the sauna forums will tell you to just drink water. The same forums are full of night-cramp threads and next-day-headache threads. Both things are real.
The difference is sweat volume. Ten minutes twice a month, water is fine. 4x a week at 175°F is not a casual habit, and your minerals know it.
The fix is not less water. It is sodium with the water, loaded before the session, so your sweat never strips you below baseline in the first place.
The 30 second pre-sauna protocol
I tried the obvious options first. LMNT gets called "very expensive salt" by its own fans, and the unflavored one gets compared to ocean water. Fair play to them, they proved people want real sodium.
But nothing on the shelf was dosed for sauna sweat. So I built it.

My 60 day self-test
Full disclosure: this is one founder and one tub, not a clinical trial. I ran the protocol on myself for 60 days before launch. Read it as exactly that.
First 2 weeks
- The 2 a.m. calf cramps stopped
- Woke up clear, no morning-after headache
- Sauna days stopped ending in a 3 p.m. crash
By day 60
- Slept like a rock on session nights
- Longer sits, 35 to 40 minutes, without the dizzy wobble
- That "clean on the inside" feeling, skin included
Your results will be yours. That is what the 30-day guarantee below is for.
Try it for 30 days

Honest answers
Why pre-sauna and not post?
Preloading sodium buffers your sweat loss in real time. Your blood sodium stays near baseline through the session instead of crashing and forcing you to play catch-up after. Post-sauna rehydration is reactive. Pre-sauna is preventive. That is the entire reason this product exists.
How is this different from LMNT?
LMNT proved that people want real sodium, and respect for that. But its own fans call it "very expensive salt," and the unflavored version gets compared to ocean water. Sauna Method is dosed for sauna sweat specifically, tastes like Pink Lemon instead of the ocean, and is sweetened with organic stevia at zero sugar and zero calories.
What does it taste like?
Pink Lemon. Real lemon flavor with organic stevia, no sucralose, no artificial colors. The sweetness is pulled back so the sodium does not read salty. Most people drink it cold over ice, 30 minutes before they sit.
Can I take it on non-sauna days?
Yes. Plenty of customers use it pre-workout, before a long hot walk, or first thing on summer mornings. The formula is built for high-sweat events, so if you are not sweating heavily, half a scoop is plenty.
When does it ship?
Orders ship in 1 to 3 business days. Tracking is sent automatically the moment your label is created.
Why not just add table salt to water?
You can, and you will probably do it once. Table salt gives you sodium only, and eyeballing 1,000mg with a kitchen spoon is a guess (a quarter teaspoon is around 575mg, so most people land way off). You also get none of the potassium, magnesium, or vitamin C, and salt water tastes like punishment. One scoop is the exact dose, the full mineral set, and it tastes like Pink Lemon.
How does the trial and subscription work?
Your first tub is free. You just cover $12.95 shipping. After that it is $40.80 every 60 days, and a fresh tub lands automatically so you never run out mid-week. Cancel or skip anytime in two clicks from your account page, no phone call, no lock-in.
Your next session does not have to cost you tomorrow
One scoop, 30 minutes before you sit. The 1,000mg your sweat takes, replaced before it leaves.
