SAUNA ON APPLE WATCH

Is there a sauna workout on Apple Watch?

Apple Watch does not include a dedicated sauna workout type. Sauna Log is built for sauna and steam room sessions, with a timer, heart rate, calories and Apple Health support.

CALORIES

How do you track calories in a sauna?

Start a Sauna Log session on Apple Watch and, when Apple provides the data, see active and total calories during the session and in your saved record.

WITHOUT YOUR PHONE

Can you use Apple Watch without an iPhone nearby?

Yes. Start and monitor the session on Apple Watch, then sync the completed record to iPhone when the devices reconnect.

How to log a sauna session on Apple Watch.

1. Choose sauna or steam room

Tap Sauna or Steam Room. The choice takes you straight to the timer screen, even if you select the currently highlighted type.

2. Choose your time

Pick one of four defaults and slide to start. Defaults are managed on iPhone and flow to the Watch.

3. Stay informed

During the session, see time remaining, live heart rate, active and total calories, and the optional cold-shower setting. Slide to stop early or add more time when the timer completes.

The timer is designed to keep its timing when the display is off. End-of-session and heart-rate alerts can use Watch haptics and notifications when enabled.

Heat conditions, when you want them.

Manual entry keeps the feature useful for public facilities and home setups without requiring extra hardware. Choose Celsius or Fahrenheit in the iPhone app and carry that preference across Apple Watch and session history.

SAUNA DEFAULT

80°C / 176°F · 10% humidity

Adjust it on the Watch for a particular room. If you leave it untouched, the iPhone record marks it as the remembered default.

STEAM DEFAULT

45°C / 113°F · 100% humidity

Separate defaults mean a regular steam room does not overwrite your sauna setting.

OPTIONAL BY DESIGN

Ignore it completely.

Temperature and humidity are there when they add context, not as another task you have to complete.
