Before we explore the impact on your phone, it’s crucial to understand the different kinds of saunas and their unique conditions.

Traditional Steam Saunas

Traditional saunas, often referred to as Finnish saunas, operate at high temperatures ranging from 150°F to 195°F (65°C to 90°C). These environments feature dry heat with low humidity levels, typically around 10% to 20%. The intense heat promotes sweating, leading to various health benefits like detoxification and improved cardiovascular health.

Infrared Saunas

Infrared saunas use infrared light to heat the body directly, operating at lower temperatures between 120°F to 140°F (49°C to 60°C). Users often report a more comfortable and prolonged sauna experience due to the milder heat. However, infrared saunas introduce additional factors like electromagnetic fields (EMFs), which some users may find concerning.

Humidity Levels and Moisture

While traditional saunas are relatively dry, humidity levels can fluctuate, especially if water is poured over heated rocks to create steam. Public saunas might have varying moisture levels due to frequent use and maintenance practices. Exposure to sauna conditions like high heat and humidity can have significant effects on both the human body and electronic devices.

Phone Usage in Sauna Environment
