Can You Wear an Apple Watch in a Sauna? The short answer? No, it's not recommended. While Apple Watches, including the rugged Apple Watch Ultra, are designed to be water-resistant, that doesn't mean they're built to handle the extreme heat and humidity of a sauna or steam room.
No - Apple advises that no Apple Watch models, including Series 2, should be used in a sauna (or a steam room).
Generally speaking, the high temperature and humidity environment of saunas and steam rooms are not friendly to watches, so it is not recommended to wear watches in saunas or steam rooms. This is because these environments may cause damage to the watch's sealing, water resistance, and resistance to various materials.
Recommended conditions for using and storing most Apple Watch models. Apple Watch is designed to work best in ambient temperatures between 32° to 95° F (0° and 35° C). You can store your Apple Watch in ambient temperatures between -4° and 113° F (-20° and 45° C).
It's best to avoid doing this unless you have a special case designed for extreme conditions. You should also consider keeping your phone outside the sauna to prevent potential damage and ensure you enjoy your sauna session without worrying about your device's safety.
Don't swim with or otherwise submerge your AirPods. Don't put AirPods in the washing machine or dryer. Don't wear AirPods in a sauna or steam room. Don't expose AirPods to high-velocity water, such as while water skiing.
A 2019 study revealed that four 10-minute sauna sessions, interspersed with 5-minute cooldowns, led to a loss of 0.65 kg, primarily from water loss. An average of 73-134 calories burned in the sauna for 10 minutes was recorded, totaling a minimum of around 200 calories burned in an infrared sauna over 30 minutes.
What is the maximum temperature that an Apple Watch can tolerate? The Apple Watch operates safely at temperatures up to 95°F (35°C). Sauna temperatures exceed this limit and can damage the watch.
Apple advises against wearing your watch in environments where it could be exposed to extreme temperatures or steam, such as hot tubs or saunas. High temperatures and steam can affect the water-resistance seals and damage internal components.
Casio's CPP-002 is a watch made for sauna use, with heat-resistant properties, an expandable wristband, and a 12-minute mode to time sauna sessions.
Your Apple Watch is water resistant, but not waterproof. For example, you can wear and use your Apple Watch during activities such as exercise (exposure to sweat is OK), walking in rain, and washing your hands.
Steam, soap or some components of a hot spring may accelerate the deterioration of water resistance performance.” “Do not wear the watch while taking a bath or a sauna. Steam, soap or some components of a hot spring may accelerate the deterioration of water resistance performance.”
Swim and shower with the Apple Watch
You can easily wear your Apple Watch when you go swimming in the sea or a pool or take a shower. You can only keep the Apple Watch Ultra on while diving, water skiing, or during other water activities. The water speed and depth would be too much for the other models.
Your Apple Watch, particularly the Apple Watch Ultra or any new Apple Watch series, is packed with delicate electronics that aren't designed to handle the kind of ambient temperatures found in saunas. The internal components could malfunction if they get too hot.
Temperature extremes can cause your watch to lose or gain time, to stop, or otherwise malfunction. Leaving your watch in an area hotter than +60°C for long periods can lead to problems with its LCD.
Ambient temperature while you're wearing Apple Watch Ultra: -20° to 55°C (-4° to 130°F) Ambient temperature while Apple Watch Ultra is charging: 0° to 35°C (32° to 95°F)
Most electronic devices are not designed to withstand the extreme conditions of a sauna. It's best to avoid using any electronic devices in such environments to prevent damage.
Another study[2] found that a 30-minute session in a sauna could burn between 300 and 500 calories, depending on current weight, metabolism, the sauna's temperature, and the time spent in it.
While the newer models of the Apple Watch, from the 3 to the 8, are waterproof 💦, they're not designed for high-temperature environments like saunas. Traditional saunas can reach up to 100 ºC, well beyond what your watch can handle. Infrared saunas, like our Clearlight range, also can cause your watch to overheat 🌡.
Can saunas help you lose belly fat? Studies show that several sauna sessions can help reduce body fat mass, BMI, and other body measurement parameters. However, it is not clear whether fat reduction targets belly fat.
Among other benefits, regular sauna use can help relax muscles, improve blood flow, and bolster skin health. The recommended length of time to spend in a sauna is 15-20 minutes. First-timers should start with five to 10 minutes. People with certain health conditions should not use a sauna.
