Can You Bring Your Phone in a Sauna? Understanding Heat, Tech & Safety
In an always-connected world, many sauna users ask: Can you bring your phone in a sauna? Whether you're timing your session, playing music, or simply want to stay accessible, the urge is real. But is it safe - for your phone or your body?
Short Answer: It Depends on the Sauna Type
Different saunas operate at different temperatures and humidity levels. Here’s how that affects your phone:
- Traditional Dry Sauna: Temperatures range from 160°F to 200°F. This extreme dry heat can damage phone batteries, warp screens, and shorten device lifespan.
- Steam Sauna: Lower temperatures (~120°F) but high humidity. Moisture is the biggest threat here, especially for non-waterproof phones.
- Infrared Sauna: Lower ambient temps (~120°F - 150°F) and no steam, which makes it safer for electronics - but still risky over time.
What Happens to Your Phone in High Heat?
Phones are typically rated to function safely up to 95°F and stored up to 113°F. Inside a sauna, those limits are quickly exceeded. Prolonged exposure can:
- Trigger thermal shutdowns
- Cause permanent battery damage
- Warp or delaminate OLED and LCD screens
- Deactivate or weaken waterproof seals
Why Some Still Take the Risk
People want their phones nearby to:
- Play guided meditations or sauna playlists
- Monitor heart rate and time sessions
- Snap aesthetic sauna selfies or videos for social media
But unless you're using a protective setup, you're playing with fire—literally.
Alternatives to Using Your Phone in the Sauna
Worried about device damage? Here are safer options:
- 🎧 Use a waterproof sauna speaker for music
- 🕒 Get a sauna-safe timer or wall clock
- 📱 Leave your phone just outside and pair with a smartwatch for alerts
Final Verdict: Should You Bring Your Phone Into a Sauna?
No, unless it's protected. Even in infrared saunas, repeated exposure to elevated temperatures can slowly degrade your phone. Steam rooms are even more dangerous due to condensation and humidity.
Until there's a better solution, leave your device outside or protect it with sauna-safe gear.
