Can I Take My Phone in the Sauna? Safety and Practicality Explained

Tempted to text from the steam room? Short answer: nope, your phone doesn’t belong in a sauna. Whether you're unwinding in a rustic outdoor sauna or enjoying some peace in a sleek indoor setup, intense heat and humidity can destroy your device. Keep reading—your phone (and wallet) will thank you later.

Taking Your Phone into the Sauna: Is It Safe?

Why the Question Arises (Connectivity vs. Relaxation)

It’s a familiar modern dilemma: you step into the sauna and immediately wonder, Should I have brought my phone in here? Maybe you’re expecting a call, tracking your fitness stats, or just want that aesthetic sauna selfie.

Let’s be honest—we’re all a little too attached to our screens. But a sauna isn’t just another chill corner of your house. It’s a place meant for deep relaxation, not replying to group chats. And while some users have dared to test the waters (or steam), the risks to your tech are real, and usually not worth it.

The Risks of Exposing Your Phone to Sauna Conditions

Heat Damage: Exceeding Operating Temperature Limits

Most smartphones work best below 35°C (95°F) and start struggling after 45°C (113°F). Step into a sauna, though, and you’re looking at temperatures soaring past 70°C (158°F)—way outside what your device can handle.

Heat like that can mess with your phone’s internals. Think: random shutdowns, screen glitches, or even warped components. If you’ve ever had your phone overheat just from lying on a sunny dashboard, imagine what a sauna can do in half the time.

Humidity and Moisture Damage: Corrosion and Malfunctions

Here’s the thing: even if the heat doesn’t get it, the humidity probably will. Traditional saunas are like a warm, foggy jungle. And while your phone might be rated as "water-resistant", steam is a different beast—it’s tiny, sneaky, and slips into gaps where water normally wouldn’t.

That’s how corrosion begins. Over time, your speaker gets muffled, your ports get finicky, and your screen fogs up. Sometimes the damage is instant. Other times, it creeps up slowly until your phone’s just... not quite right anymore.

Potential Damage: Battery Failure, Screen Issues, Component Stress

High heat doesn’t just stop at surface-level issues. Your battery is at risk of swelling, which sounds dramatic—and it is. It could reduce performance, shorten battery life, or in rare cases, lead to safety hazards.

Screens can discolour, touch response can fade, and internal circuits may degrade. Even a quick 10-minute sauna session could be enough to cause permanent harm. If you're unlucky, your phone might survive once, but each visit chips away at its health.

Does Sauna Type Matter? (Traditional vs. Infrared)

Kind of—but don’t get your hopes up.

Infrared saunas run a bit cooler (usually around 50–60°C), and they heat your body more than the air around you. But even then, that’s still too hot for most smartphones to operate safely. Plus, moisture can still be present, especially from your own sweat and body heat.

In traditional saunas, it’s even worse. You’ve got soaring temperatures and steam working together to create a phone-destroying storm. No matter the type—infrared, steam, dry, or outdoor cabin-style—your phone is better off sitting this one out.

Sauna Etiquette and Phone Use

Disrupting the Relaxation Environment

Saunas are like sacred spaces. You walk in, take a deep breath, and just be. That peace? It shatters the moment someone pulls out a phone.

Even if you’re silent, the glow of the screen and the constant tapping ruins the atmosphere. People come here to disconnect—bringing a phone into the mix goes against everything a sauna stands for. And frankly, it's a little rude.

Privacy Concerns in Public Spaces

Let’s also talk privacy. In public saunas, phones raise eyebrows. No one wants to be in the background of a sweaty stranger’s selfie, especially when towels are involved.

Most wellness centres have clear rules against using devices inside for this reason. It’s about comfort and respect. Nobody wants to second-guess if they’re being recorded while trying to unwind.

Alternatives to Bringing Your Phone Inside

Enjoying a Digital Detox

Think of your sauna session as a little escape hatch from your digital world. Leave your phone behind, breathe in the steam, and let your mind wander without a screen in sight.

Even 15–20 minutes offline can feel like a full mental reset. You’ll walk out feeling clearer, lighter, and honestly, proud that you didn’t check your notifications. This is your permission to fully unplug.

Using Waterproof/Heat-Resistant Speakers (If Allowed)

Need music or a timer? Opt for a heat-resistant Bluetooth speaker or waterproof smartwatch, if your spa allows it. Keep it on the bench near the entrance or just outside the door.

That way, you get your background tunes or fitness tracking without turning your phone into a melted mess. Always check facility rules first, though—not every sauna welcomes tech companions.

Conclusion: Leave Your Phone Outside the Sauna

Let’s wrap this up with the truth: your phone does not belong in a sauna. Between the intense heat, high humidity, and potential for costly damage, it’s just not worth the risk.

Whether you’re enjoying a cosy indoor infrared session or sweating it out in a scenic outdoor cabin, your device needs a break just as much as you do. Respect the space, protect your tech, and embrace the chance to disconnect for a little while.

Who knows—you might even enjoy the silence.
