How Apple Watch Measures Sauna Sessions

Apple Watch does not have a dedicated sauna tracking mode, but it can still record relevant metrics during your sauna sessions using its existing sensors. The watch primarily relies on heart rate monitoring, temperature sensors, and motion data to infer physical conditions while you are in the sauna. However, it is important to note that the watch is not explicitly designed to track prolonged exposure to high heat environments, so its readings may vary in accuracy.

During a sauna session, the Apple Watch continuously monitors your heart rate, which typically elevates due to the heat stress and cardiovascular response. This data is logged within the Workout app under a generic workout type such as “Other” or “Mind & Body,” unless you manually select a specific category. Additionally, the watch tracks active calories burned, which can give an approximation of the metabolic demand during the session.

The watch’s ambient temperature sensor is limited and primarily used for environmental awareness rather than continuous heat exposure tracking. Consequently, the Apple Watch does not provide a direct measurement of sauna temperature or humidity levels, which are key factors in sauna therapy.

Limitations and Considerations When Using Apple Watch in Saunas

While the Apple Watch is water-resistant, it is not designed to withstand the extreme heat and humidity typical of sauna environments. Apple officially advises against wearing the watch in temperatures exceeding 45°C (113°F), which is often lower than the temperature inside many saunas. Prolonged exposure to such heat can:

  • Affect the watch’s battery performance and longevity.
  • Cause inaccurate heart rate and sensor readings.
  • Potentially damage the device’s hardware components.

Users should exercise caution and consider removing the watch during sauna sessions to prevent damage. If tracking is desired, short sauna intervals under the recommended temperature limits can be attempted, but the data should be interpreted with caution due to possible inaccuracies.

Manual Tracking and Third-Party App Options

Since the Apple Watch does not natively support sauna tracking, users often rely on manual logging or third-party applications to better capture sauna sessions. Some apps allow you to create custom workouts or log sauna time with additional notes on temperature and humidity, which can be useful for health monitoring.

Key features offered by third-party apps for sauna tracking include:

  • Customizable workout types to label sauna sessions.
  • Manual input fields for sauna temperature and duration.
  • Integration with HealthKit to consolidate sauna data with other health metrics.
  • Reminders for hydration and cooldown periods post-sauna.

These apps can enhance your ability to monitor the physiological effects and benefits of sauna use when combined with Apple Watch data.

Comparison of Apple Watch Sauna Tracking and Dedicated Sauna Trackers

Dedicated sauna trackers or smart sauna devices typically offer more specialized features tailored to sauna environments, such as real-time temperature and humidity monitoring, session timers, and safety alerts. Below is a comparison table highlighting key differences:

Feature Apple Watch Dedicated Sauna Tracker
Temperature Monitoring Not supported (ambient sensor limited) Real-time, accurate sauna temperature
