Do you often ask yourself, “Can I bring my iPhone in a sauna?” If yes, then this blog will help you out. We know that iPhones are durable and water-resistant. However, we still have not two or three but seven reasons why you should never ever bring your iPhone into a sauna. Read them carefully, and if you still believe you can take your iPhone into sauna, then it’s all your choice. So, let’s dive in!

7 Reasons Why You Should Not Bring Your iPhone In Sauna

Can I Bring My iPhone In A Sauna?

If you want to find “Can I Bring My iPhone In A Sauna”?, you have to know about the risks you can face by bringing your iPhone in a sauna.

Here are the  reasons why you should not bring your iPhone in sauna:

Extreme Heat

It is not recommended to bring your iPhone in a sauna because of the serious risks caused by extreme heat. The high temperatures in saunas can harm the internal parts of your phone, even if it looks fine on the outside. Saunas are designed to relax you, but exposing your iPhone to such conditions can damage its delicate components. The heat might warp or melt parts of your device, and the battery could lose its ability to hold a charge or even stop working properly over time.

Infrared saunas are even worse for phones since they heat objects directly, making your iPhone overheat faster compared to traditional steam saunas. Without a special sauna-safe case, which is hard to find, your phone could face costly damage or even total failure.

Humidity and Moisture

Humidity and moisture are the main reasons why bringing your iPhone into a sauna is a bad idea. Saunas are filled with steam, which can seep into your iPhone through tiny openings like the charging port or speakers. Once it goes inside the phone, the moisture can cause corrosion to the internal components, leading to permanent damage.

Even though many iPhones are water-resistant, they are not built to endure prolonged exposure to high humidity levels. Over time, this can weaken the seals that protect your phone, making it more vulnerable to water damage. Additionally, condensation can form inside the device as it goes from the hot sauna to a cooler environment, causing further harm.

No Steam Resistance

iPhones are not steam resistant, so they can easily be damaged in steamy environments like a sauna. The steam from hot water contains tiny moisture droplets that can enter the phone through small openings like the charging port or speaker grilles. Since iPhones are designed to be water-resistant, they are not built to handle the constant exposure to steam, which can weaken the protective seals over time.

If you bring your iPhone to a sauna, your phone can face several problems like moisture can reach the internal parts of the phone, leading to corrosion or short circuits. Also, this may cause a malfunctioning screen, reduced battery life, or complete hardware failure. The heat in the sauna can also overheat the phone, damaging the battery or causing the phone to shut down unexpectedly.

Battery Heatup

Batteries are the real issue for iPhones in hot environments like a sauna. When an iPhone’s battery overheats, it can cause serious problems for the device. High temperatures can force the battery to expand, which may permanently damage the internal components or even cause the phone to stop working entirely.

Heat also greatly affects the battery percentage of iPhones. An iPhone with a battery health of a minimum of 80% is considered a good number. Anything below this usually requires you to change the battery. When the battery gets too hot, its ability to hold and deliver a charge is reduced. This means the battery may drain much faster than usual, even if you’re not using the phone heavily.

Constant overheating can lead to long-term damage, like a shorter battery lifespan or the device shutting down unexpectedly. Keeping your iPhone in a cool and dry environment is the best way to protect both the battery and the phone itself.

Decreased Brightness

At high temperature areas like saunas, when iPhones heat up, they decrease the brightness of the phone. This happens as a protective measure to prevent overheating, which can harm the internal components of the device. The brightness level is automatically reduced by the phone’s system to lower power consumption and minimize the heat generated by the screen.

Saunas are known for their high heat and humidity, which creates an environment where electronic devices like iPhones can struggle to stay cool. Overheating in such conditions can cause the device to temporarily change its performance, with reduced brightness being among the first noticeable effects. This adjustment helps preserve the phone’s functionality and avoid permanent damage to the screen or battery. So, what’s the cause of bringing iPhone in sauna when you can’t use it at low brightness?

Damaged Camera Lens

One of the main reasons of buying iPhones is because of its camera, which provides exceptional photo and video quality. However, exposing your iPhone to a sauna’s extreme heat and humidity can severely damage its camera lens. Saunas often reach temperatures which iPhone designs can’t handle, and the combination of heat and moisture can cause condensation to form inside the device. This condensation can blur the camera lens or even lead to permanent damage, such as cracks or fogging.

The camera’s delicate hardware components may warp under high heat, resulting in reduced image quality or complete failure of the camera. To protect your iPhone and keep its camera functioning at its best, it’s important to avoid bringing it into environments like saunas where the temperature and humidity levels are too extreme. Your iPhone’s camera is a valuable feature that deserves proper care to ensure it lasts for years to come.

Faulty Speakers

In saunas, the intense heat and high levels of humidity can have a harmful effect on your iPhone’s speakers. The moisture in the air can seep into the tiny openings in the speaker grille, causing condensation to form inside. This can lead to muffled sound, reduced volume, or even total failure of the speakers over time.

So, to prevent these issues, it’s best to avoid bringing your iPhone into a sauna. Keeping your device in a more stable environment protects its delicate parts, including the speakers, and helps ensure it continues to work properly. Your iPhone is an investment, and taking care of it is essential to keep it performing well.

If you can’t live a few minutes without your iPhone, it’s better to stay addicted to it and stop your self-care routine. Because if you take the iPhone with you, you are wasting your time in sauna and also risking your iPhone going out of order.
