Apple Watch in Sauna: Safety Guidelines and Insights 💡

by | Feb 27, 2023

Quick Answer:

Apple Watch devices are not engineered to endure the elevated temperatures and intense humidity typical of saunas. While the Apple Watch Ultra offers slightly enhanced resilience, it’s advisable to avoid wearing any Apple Watch variant in sauna environments to ensure optimal functionality and longevit

The Apple Watch has rapidly become an essential device for many, seamlessly integrating health tracking and digital connectivity.

With the growing popularity of saunas for their numerous health benefits, it’s only natural to wonder if you can combine the two.

So, can you safely wear your Apple Watch in the sauna?

Apple Watch in Sauna: Can You Do It?

No, you can’t wear your Apple Watch in a sauna or steam room, unless the sauna operates at a temperature lower than what the Apple Watch can handle.

The allure of wearing your Apple Watch everywhere is understandable. However, the sauna is a notable exception.

Every Apple Watch, except the Ultra 1 and Ultra 2, are made to function optimally between 32° to 95° F, per Apple.

On the other hand, the Apple Watch Ultra 1 and Ultra 2 boast a slightly broader range, from -4° to 130° F.

With typical saunas exceeding 150°F, it’s clear that the Apple Watch and saunas aren’t a match made in heaven.

Waterproof vs Water-Resistant

While many smartwatches tout their resistance to water, understanding the terminology is key to ensuring the longevity of your device.

Waterproof and water-resistant are terms that often get mixed up, but there’s a big difference between the two.


A watch that is water-resistant can endure some water exposure to whatever depth the manufacturer states.

However, it might face challenges if fully submerged or exposed for prolonged periods.


A watch that is waterproof can be submerged in water without any repercussions.

Still, even these watches can lose their resistance over time.

With that said, Apple Watches are water-resistant.

Despite them having a swimming setting, and the Ultra being designed for diving, they are not technically waterproof.

The Apple Watch Ultra and Ultra 2 are resistant to 100m, while the Series 8, Series 9, and SE have resistance to 50m.

Effects of Sauna/Steam Room Exposure on Your Apple Watch

Subjecting your Apple Watch to the conditions of a sauna or steam room could result in:

  • Potential thermal shutdown due to overheating.
  • Display anomalies, including lines or discolorations.
  • Decreased battery lifespan.
  • External screen deterioration or warping, or popping off.
  • Diminished effectiveness of its water-resistant properties over time.

Is the Damage Reversible?

While some effects of sauna exposure, like temporary malfunctioning, may be reversible, others can lead to lasting damage.

Short-term issues like screen anomalies or minor battery drainage might self-resolve or be addressed with professional intervention.

However, long-term implications, like compromised water resistance or persistent battery issues, may not be fully reversible.

Each case varies, so consultation with an expert is recommended if your watch exhibits any abnormalities after sauna exposure.

Remember, internal moisture indicators triggered by steam could void your warranty, emphasizing the importance of prevention.

Apple Watch Won’t Work After Going In Sauna

Should you inadvertently expose your Apple Watch to sauna heat and it malfunctions, a reset might be your first course of action.

If this fails, seeking assistance from Apple Support is your next step, as the watch may have suffered internal damage.

If your watch still functions after sauna exposure, activate the water lock feature and then deactivate it to eject any trapped moisture.

Important! Water-lock doesn’t prevent water from entering the watch, all it does is use sound waves to push any water back out of the watch. This feature does not make your watch water-proof.

Additionally, ensure the exterior is dried thoroughly.

Do not shake your Apple Watch to get moisture out! This may cause water to go deeper into it.

Key Takeaways

When enjoying the serenity of a sauna, it’s best to leave your Apple Watch behind. A few essential points to bear in mind include:

  • Apple Watches, barring the Ultra 1 and Ultra 2, have a max operating temperature of 95° F. The Ultra line can withstand up to 130° F.
  • Sauna temperatures can adversely affect the watch’s components.
  • The extreme heat of saunas surpasses the designed resistance of even the most advanced Apple Watches.
  • Keeping your Apple Watch out of the sauna ensures its peak performance and extends its life.

Frequently Asked Questions

Is Apple Watch safe in infared sauna?

Even though the Apple Watch has some resistance against moisture, the elevated temperatures of any sauna, including infrared ones, can harm its internals and potentially void its warranty.

Can I wear Apple Watch Ultra in the sauna?

While the Ultra has a higher tolerance, saunas typically exceed its highest operating temperature, making it ill-advised to wear it there.

Can I wear Apple Watch 7 in the sauna?

Given that the Series 7’s maximum operating temperature is 95° F and saunas go well beyond this, it’s not recommended to wear it inside a sauna.
