Sauna & Your Phone: Should You Bring It In? (iPhone and Android)

The sauna is a place of relaxation, detoxification, and rejuvenation. It's a sanctuary where we can escape from the hustle and bustle of daily life, and immerse ourselves in a world of warmth and tranquility. But in this digital age, our smartphones have become an integral part of our lives. So, the question arises, should we bring our phones into the sauna? Let's delve into the implications for both iPhone and Android devices.

The Effects of Heat on Your Phone

Heat and Your Phone's Battery

Smartphones are complex devices, and their components are sensitive to extreme temperatures. One of the most affected parts is the battery. Lithium-ion batteries, which are commonly used in smartphones, can suffer from reduced capacity and lifespan when exposed to high temperatures. In fact, Apple recommends using iOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F).

Similarly, Android manufacturers like Samsung and Google also caution against exposing devices to temperatures above 35º C (95º F). Prolonged exposure to heat can cause the battery to swell, potentially damaging the phone's internals or even causing it to explode in extreme cases.

Heat and Your Phone's Performance

Heat doesn't just affect your phone's battery, it can also impact its performance. When a smartphone is exposed to high temperatures, it may automatically limit its performance to reduce heat generation. This can result in slower processing speeds, reduced screen brightness, and limited functionality for certain apps and features.

Both iPhones and Android devices have built-in thermal sensors that trigger these protective measures. So, if you've ever noticed your phone becoming unusually slow or dim after leaving it in a hot car or in direct sunlight, that's the reason why.

Health Implications of Using Your Phone in the Sauna

Distraction from Relaxation

The sauna is meant to be a place of relaxation, a sanctuary from the stresses of daily life. Bringing your phone into the sauna can distract from this purpose. Instead of focusing on your breathing, the warmth of the sauna, and the relaxation of your muscles, you might be tempted to check emails, scroll through social media, or text.

Moreover, the bright light from your phone's screen can disrupt the calming, dimly lit atmosphere of the sauna. It's important to remember that the sauna experience is not just about physical detoxification, but also mental relaxation. Disconnecting from digital devices can enhance this experience.

Potential Health Risks

While the research is still limited, some studies suggest that prolonged exposure to the electromagnetic fields (EMFs) emitted by smartphones could have potential health risks. These may include headaches, sleep disturbances, and even increased risk of certain types of cancer. While the World Health Organization has classified EMFs as possibly carcinogenic, more research is needed to fully understand the long-term effects.

By bringing your phone into the sauna, you're not only exposing yourself to these EMFs in a confined space, but also potentially increasing your exposure time if you're using your phone instead of relaxing or meditating. It's always a good idea to consult your doctor when considering sauna therapy, especially if you have any health concerns or conditions.

How to Safely Use Your Phone in the Sauna

If you still decide to bring your phone into the sauna, there are a few precautions you can take to protect your device and yourself:

  • Limit your sauna sessions: To prevent your phone from overheating, limit your sauna sessions to 15-20 minutes at a time.
  • Use a protective case: A heat-resistant case can help protect your phone from the high temperatures in the sauna.
  • Keep your phone off your body: To reduce your exposure to EMFs, keep your phone off your body and use it sparingly.

Remember, every person is different, and what works for one person may not work for another. Always listen to your body and consult your doctor if you have any concerns.


While our smartphones have become an integral part of our lives, there are times and places where it's best to disconnect. The sauna is one of these places. Not only can the heat damage your phone, but using your phone in the sauna can also distract from the relaxation and detoxification benefits of the sauna experience.

So, next time you're heading to the sauna, consider leaving your phone behind. Your mind and body (and your phone) will thank you.
