LOOK CLOSER.

I built this because I needed it to exist.

Two years into a 4 to 5 session a week sauna habit, I started noticing a pattern I could not explain.

The sessions themselves felt fine. 20 minutes at 180°F, a cold plunge, repeat. Standard stack.

It was the hours after that broke me.

The drive home with my hands going light on the wheel. The post sauna headache that sat behind my eyes for the rest of the night. The 2am calf cramp that shot me out of bed and left me limping for two days. The next morning crash where my heart rate would not come down and I felt hung over without drinking.

I was doing everything the protocols said. Hydrating before. Hydrating after. Drinking water on the bench.

I was still wrecked.

I assumed I was over training. I cut a session per week. Same headaches. I cut caffeine. Same cramps. I started sleeping nine hours instead of seven. Same flat next day.

Then I read a paper that changed how I think about heat exposure entirely.

What the research actually says.

Two names you should know if you take the sauna seriously.

Dr. Susanna Søberg (Copenhagen, deliberate cold and heat exposure researcher). Her work on contrast therapy has shaped the protocols Huberman and Attia talk about. The piece most people miss: Søberg's framing treats heat exposure as a controlled stressor that demands a recovery input. The sauna is the load. Mineral replacement is part of the recovery. Skip the recovery input and you are accumulating stress, not adapting to it.

Dr. Jari Laukkanen (University of Eastern Finland, 20 year cohort study on Finnish sauna users). His landmark data showed that men who used the sauna 4 to 7 times per week cut cardiovascular mortality risk by roughly 50% compared to once a week users. All cause mortality dropped 40%.

That is the headline most people stop at.

The footnote that matters more for you: those benefits assume the user is recovering between sessions. Chronic dehydration, electrolyte depletion, and the compounding nervous system load of unreplaced minerals erode the adaptation. You can sauna 5 times a week and still be net negative if every session leaves you depleted into the next one.

The Laukkanen cohort were lifelong Finnish sauna users. They were not white knuckling through sessions on tap water. They were eating salt heavy traditional diets, drinking mineral rich well water, and treating the sauna as a daily ritual their bodies were adapted to support.

If you are saunaing 4 plus times per week on an American diet and bottled water, you are running the Laukkanen protocol with none of the Laukkanen recovery infrastructure.

That gap is what Pre-Sauna Electrolytes was built to close.

You are losing 1,000mg of sodium in a single 30 minute session.

This is the cramp number. The dizziness number. The reason you feel light headed standing up off the bench.

Sodium runs your nervous system, your muscle contractions, and your blood pressure regulation. Lose 1,000mg in 30 minutes without replacing it and your body does exactly what it should do. It pulls fluid out of your bloodstream to maintain mineral concentration, your blood pressure drops, your head spins, and 8 hours later your calves seize at 2am because your muscles cannot fire cleanly on a depleted sodium pool.

Pre-Sauna Electrolytes delivers 1,000mg of sodium per serving. Pre-loaded 20 minutes before you walk into the room. The math is built to match what the heat is about to take.

What it prevents:

• Mid session dizziness and light headedness
• The post sauna headache that sits behind your eyes
• 2am calf cramps that wreck the next day

What goes in matters as much as what comes out.

The question I get the most: if you are putting something in your body 4 to 5 times a week, what is in it?

Here is every ingredient in Pre-Sauna Electrolytes, with the reason it is in the tub.

Manufactured in Long Island, NY. Third party tested. Founders pricing tier is the first 500 customers.

Why I went to Long Island to make this.

I looked at every co manufacturer in the Midwest and the South before settling on the Long Island facility.

Two reasons.

First, the formulation control. The sodium to potassium to magnesium ratio in Pre-Sauna Electrolytes is built for the 180°F heat profile, not for the generic endurance market. Most co packers pushed me toward an off the shelf formula with maltodextrin and a sugar carrier because that is what their lines were tuned for. The Long Island facility built the formula I specced, with the magnesium glycinate (not malate, not oxide) and the vitamin C dose I wanted.

Second, the testing transparency. Third party tested. Heavy metals panel. Microbial panel.

This is a single SKU brand right now. One tub. Pre-Sauna Electrolytes, Pink Lemon. $48 one time, $40.80 on the bimonthly subscription. Founders pricing for the first 500 customers, then the price moves.

I saunaed 4 to 5 times a week for two years before I built this. I built it because I needed it to exist and nothing on the shelf was solving for the sauna math.

If the product works for you the way it works for me, the subscription is there. If it does not, the money back guarantee is real and the cancel button is one click.
