Field notes
Session entries can include temperature, humidity, sauna type, mood, stress, breaks, cool-downs, and water. The app also lists estimated sweat and electrolyte losses, while Apple Health comparisons cover sleep, HRV, and resting heart rate. The site describes a 30-day experiment against the preceding month and cautions that heart rate is a guide, not a medical measurement.
