Saunas are a popular way to relax and unwind, offering a therapeutic experience. With the prevalence of smartphones in our daily lives, it is natural to wonder if it is safe to use an iPhone in a sauna. After doing my research, I strongly advise you not to use your iPhone in the sauna.

In this article, I’ll give you four potential risks associated with using an iPhone in a sauna environment then provide you with some of the best practices for your phone while in the sauna.

4 Risks of iPhone Use in The Sauna

Heat and Moisture Exposure

Saunas are characterized by high temperatures and humidity levels. iPhones, like any electronic device, are not designed to withstand extreme heat or excessive moisture. Exposure to these conditions can potentially damage the internal components of the device. Excessive heat can cause the battery to overheat, affecting its performance and potentially leading to battery degradation or even swelling. Moisture can also seep into the phone, damaging the circuitry and rendering the device inoperable.

Risk of Screen Damage

The heat and humidity in a sauna can have adverse effects on the iPhone’s screen. Exposing the device to high temperatures can cause the screen to expand, leading to possible distortion, discoloration, or even cracking. Additionally, the moisture in the sauna can accumulate on the screen, making it difficult to operate the device and potentially causing damage to the touch screen functionality.

Safety Concerns

Using an iPhone in a sauna may pose safety risks. Excessive heat can make the device uncomfortable to hold or touch, potentially causing discomfort or even burns to the user. Moreover, the slippery environment in the sauna, combined with the distraction of using a phone, increases the risk of accidental drops or damage to the device.

Warranty and Manufacturer Guidelines

Most iPhone warranties explicitly state the devices are not intended to be used in high-temperature or high-humidity environments like saunas. Using an iPhone in a manner inconsistent with the manufacturer’s guidelines may void the warranty, leaving you responsible for any repair or replacement costs.

Recommended Practices

To ensure the safety of your iPhone and to prevent potential damage, here are some recommended practices:

  • Leave your iPhone outside the sauna: It is best to keep your phone in a safe and dry place outside the sauna. This will protect it from the extreme temperatures and moisture inside the sauna.
  • Use a waterproof storage container: If you must bring your iPhone into the sauna area, consider using a waterproof storage container or a sealed plastic bag to protect it from moisture and humidity.
  • Allow your iPhone to cool down: If your phone has been exposed to the high temperatures of the sauna, give it time to cool down before using it. Sudden changes in temperature can be detrimental to electronic devices.
  • Utilize alternative methods for entertainment: Instead of using your iPhone in the sauna, focus on relaxation techniques, such as listening to calming music or engaging in meditation exercises that do not require electronic devices.


Using an iPhone in a sauna environment poses potential risks to the device due to the high temperatures and humidity. To ensure the safety and longevity of your iPhone, it is advisable to keep it outside the sauna or in a waterproof container. Following the manufacturer’s guidelines and exercising caution will help prevent damage and ensure a pleasant and worry-free sauna experience. Remember, the sauna is a place to unwind and focus on relaxation, so disconnecting from your phone can enhance the benefits of this therapeutic environment.
