Watch Fit 5 Pro - sauna overheating
I wore my new Watch Fit 5 Pro in the sauna for the first time today. It overheated and did an auto switch off after a message came up about overheating. Obviously it was really hot in there. However, I wore my previous watch (Garmin Venu Sq 2) in the sauna without any such problem. I'm guessing that it's due to the 5 Pro having metal surround whereas the Garmin is all plastic. Next time I'm going to wrap a cloth around the watch and see if that helps.
Not sure if there's a general issue with the 5 Pro overheating. Of course a sauna is an extreme heat environment! However I see many other people wearing smart/fitness watches in the sauna without issues.
