WARNING FOR ATHLETES WHO SAUNA: Never Sit in the Heat Without "Targeted Cooling" (or you could be risking your natural testosterone)

01

1. Your Testicles Cannot Bear Regular Sauna Heat

There's a reason your testicles sit outside your body instead of inside it with everything else.

They need to stay a few degrees cooler than your core. Sperm production works best in that cooler range, and your body works hard to keep it there.

A sauna takes that away. The air in there is 80 to 90°C, and your balls get hit with the same heat as the rest of you, with nothing but a towel or a pair of shorts in between.

2. Your Balls' Natural Cooling System Stops Working When The Air Is Hotter Than Your Body

Every guy knows that when it's cold, your balls pull up close to your body. And when it's hot, they hang lower.

That's your body's cooling system at work. Letting them hang lower moves them away from your body heat, and a network of veins around them cools the blood before it reaches them.

That works on a hot summer day, because the air around you is still cooler than your body.

In a sauna, the air is 80 to 90°C. Hanging lower doesn't help when the air they're hanging into is hotter than you are.

Add a hot wooden bench underneath and your thighs pressed on both sides, and there's nowhere for that heat to go.

So the system your body relies on to protect your balls basically shuts off the moment you sit in the sauna.

3. Heat Lowers Your Sperm Count, Which Can Make It Harder To Have Kids Later

Researchers at the University of Padova wanted to see what regular sauna use does to healthy men.

Ten men sat in a sauna for 15 minutes, twice a week, for three months. That's a normal routine, and lighter than what a lot of guys who train are doing.

By the end, their sperm count had dropped by around 58%, and the sperm that were left didn't swim as well.

That's why male fertility doctors commonly tell men who are trying for a baby to stay out of saunas and hot tubs completely. Even one of the Padova researchers said men going through fertility treatment should avoid heating their testicles.

Even if you’re not planning for a kid, it's worth paying attention to.

4. Your Training Is Already Draining Your Testosterone. It Doesn't Need More Heat.

Every guy knows that when it's cold, your balls pull up close to your body. And when it's hot, they hang lower.

That's your body's cooling system at work. Letting them hang lower moves them away from your body heat, and a network of veins around them cools the blood before it reaches them.

That works on a hot summer day, because the air around you is still cooler than your body.

In a sauna, the air is 80 to 90°C. Hanging lower doesn't help when the air they're hanging into is hotter than you are.

Add a hot wooden bench underneath and your thighs pressed on both sides, and there's nowhere for that heat to go.

So the system your body relies on to protect your balls basically shuts off the moment you sit in the sauna.

5. Cooling Your Balls Lets You Sauna Without Gambling Your Testosterone or Future Kids

There's one more thing the Padova researchers found that most people never hear about.

After the men stopped going to the sauna, their sperm count came back up.

That changes how you should think about the whole problem. The damage came from heat reaching their balls, and heat is something you can control.

That's where targeted cooling comes in. A cold source sits directly beneath your testicles and keeps drawing heat away from them for the whole session, something your body can't do on its own in 80 to 90°C air.

THE PRACTICAL FIX

SaunaArmor: Targeted Cooling Built Into A Pair Of Briefs

SaunaArmor builds targeted cooling into a pair of sauna briefs. While the sauna heats your balls from the outside, a frozen insert cools them from underneath at the same time, so the rest of your body still gets the full session.

✓ Cooling right where it's needed: a built-in pouch holds the insert directly beneath your testicles.

✓ Completely hands-free: the insert stays in place while you sit, lean back or shift positions, so there's nothing to hold or adjust.

✓ No ice against your skin: a fabric layer sits between you and the insert, so the cold stays steady instead of numbing.

✓ Made for a normal session: the insert is designed to last through a typical sauna session.

✓ Two reusable inserts included: they're BPA-free, so one can stay in the freezer while you use the other.

✓ HeatPure™ 100% cotton body: you won't be sitting in the sweaty polyester shorts you trained in.

✓ Looks like normal underwear: nobody in a gym sauna will know you're wearing anything different.

THE COMPARISON

Why Not Just Use an Ice Pack?

Some guys try cooling their balls with a bag of ice or a gel pack. It might work for a few minutes, then it slides every time you move, goes warm halfway through, leaves you holding it between your legs in a shared sauna, and gets you all the weird stares from the whole room, thinking what the hell are you doing over there.
