Monk vs ColdLog

All with the ability to track your progress against key plunge and health metrics like sleep, heart rate and HRV. Designed to work with any cold body of water – the sea, wheelie bins, or your DIY cold plunge and Monk's smart ice bath for the ultimate experience. Who are you on the other side of the ice? ACCLIMATISATION PROGRAMMES Whether you’re a beginner or want to reignite your connection to the cold, our signature programme will guide you from 10°c all the way down to 3°c, safely and effectively. You’ll learn exactly what’s happening in your body in each immersive plunge. This programme will respond to your pace, and once you reach your new baseline of two minutes at 3°c, you’re ready to explore our further programmes with confidence. We've seen users go from 20 seconds in a bath to 6+ minutes in a week. SYNC YOUR WEARABLES You can’t manage what you can’t measure. Monk integrates with your wearables, like Whoop, Oura, Garmin, Fitbit and many more, so that you can see how cold exposure impacts important health biometrics over time, like HRV and sleep, all in the Monk dashboard. DATA DASHBOARD Monitor and optimise your biometric data and see how cold exposure is impacting important health metrics like HRV and sleep over time. CONTROL YOUR MONK ICE BATH (OPTIONAL) Change the temperature, set schedules and get reminders about your plunges.
