Apple Watch to the sauna – is that a good idea? the Apple Watch has many useful applications in the health field and is becoming an increasingly important wrist gadget for many users. I have also used the sports watch in steam baths and saunas after training. Over time I have both the Apple Watch Tried Ultra as well as the Series 8, Series 7, Series 6 and the previous models in the sauna. In the Apple Watch Ultra there is a special feature. So much in advance: Apple Watch Sauna is possible - but only under certain safety precautions - and of course at your own risk. All tips, tricks, experiences and advice can be found in my experience report.
