For many of us, our iPhones have become an indispensable part of our daily lives.

But, with the popularity of saunas, the question has arisen of whether or not it is safe to use our iPhones while sitting in the sauna.

In this comprehensive guide, we will explore the official guidelines from Apple along with opinions of regular people, as well as discuss the potential risks and benefits of using your iPhone in the sauna.

What Apple says

Let’s have a look at what Apple says about using iPhones in a sauna.

According to Apple, iPhones are designed to work in temperatures ranging between 32°F and 95°F (0°C and 35°C). Meanwhile, their non-operating temperature range is between -4°F and 113°F (-20°C to 45°C).

A dry sauna can easily reach temperatures of 60°C, while a traditional sauna in Finland can reach 80-90°C.

These high temperatures can cause your iPhone to overheat and turn off in order to avoid potential damage.

Water / moisture

According to Apple’s official website, iPhones are tested under controlled laboratory conditions and rated for water and dust resistance.

Some iPhone models have a rating of IP68, which means they are splash, water, and dust resistant, but the maximum depth and duration vary by model. For example, the iPhone 14, 14 Plus, 14 Pro, and 14 Pro Max have a rating of IP68 under IEC standard 60529, with a maximum depth of 6 meters up to 30 minutes.

However, sauna conditions are not part of these laboratory tests, and Apple explicitly advises against using iPhones in a sauna. The high heat and humidity can cause permanent damage to the device, reducing its lifespan and performance.

In addition to the high heat, exposing your iPhone to soap, detergent, acids, lotions, and other substances can also cause damage. For example, the intense steam in a wet sauna can get inside your iPhone’s camera lens, causing photos to appear blurry and putting your battery’s health at risk.

The high humidity can cause water damage, even if you don’t intentionally submerge your iPhone in water.

Moreover, older iPhones are not as water-resistant as newer models, and the intense heat and moisture of the sauna environment can trigger the submersion indicator, even in phones with a headphone jack. In some cases, using your iPhone in the sauna may result in water damage, and warranties for repairs may not be honored.

Brief periods of time are probably OK, but still not recommended

Some people have noted that it is possible to use an iPhone in the sauna for a brief period of time, but with the risk of overheating and damaging the device.

Others recommend leaving the phone in the changing room or on the floor of the sauna (away from the heater) if you simply want to be available in case of an emergency call.

What to do if you brought your iPhone into a sauna?

If you accidentally bring your iPhone into a sauna, it’s important to take immediate action to protect your device. Remove it from the sauna as soon as possible and turn it off. Leave it in a dry area with some airflow and avoid charging it until it’s completely dry.

To prevent damage to your iPhone, avoid exposing it to extreme heat and humidity. If you want to use your device in a sauna or steam room, it’s best to leave it in a safe and dry place outside the sauna. If you need to take a call or check your messages, bring a separate device specifically designed for these conditions.


In conclusion, while using your iPhone in the sauna may not be ideal, it is possible with newer models and for brief periods of time.

However, the intense heat and humidity of the sauna environment can put your device at risk of damage and potentially void your warranty.

To be on the safe side, it is best to simply enjoy the warmth and serenity of the sauna without your device.
