Hot Cold: Sauna & Cold Plunge Tracker

Cold plunge, sauna and contrast therapy on your wrist. Hot, cold and rest rounds in one activity, big white digits you can read wet and in the dark, and a session saved to Garmin Connect with your heart rate and the temperatures you enter. One purchase. No licence codes, no phone app, no trial, no subscription. WHAT IT DOES - Three modes: Sauna, Cold Plunge, Contrast (hot → cold → rest, repeated, with a round counter). - Set a target for each phase, or leave it open. A buzz tells you when the target is reached; the phase only changes when you press START, so the timer never throws you out of the plunge early. - Every phase is a lap in Garmin Connect, with its own time and heart rate. - Enter your sauna and water temperature at the end (°C or °F). They are saved into the activity. - Live heart rate, wrist temperature where your watch has a sensor, and the time of day on the session screen. - Dim mode for dark saunas. Vibration off, gentle or strong. Optional buzz every minute. MADE FOR WET HANDS - Touch is ignored during a session, so water drops cannot flip a phase. - Water guard: START and BACK need a second press within 1.5 seconds. Turn it off in Settings if you prefer. - Works with just START and BACK on every watch. CONTROLS UP/DOWN: mode · START: begin · START: next phase · BACK: pause menu (resume, next phase, end and save, discard) · UP/DOWN during a session: dim · MENU: settings. SAFETY Garmin rates its watches to 45 °C; saunas run at 70 to 100 °C. Wearing a watch in a sauna is at your own risk and may void the warranty. Cold plunge and contrast therapy are within the watch's rating.
