I have been using Apple Watch SE (1st gen) since September 2022. Recently, I look at my Resting heart rate (RHR), and it shows me that my RHR has been increasing. The spike was on 23-24 Jan 2023, which was the time I updated the WatchOS to the latest version at that time.
The RHR chart in the following days, up until now, seems to be higher than the previous months. I initially thought that my health was getting worse, but when I checked with my friend who used AW SE 2nd gen, he also started to have an increase in RHR on 23-24 Jan, the time he also updated the WatchOS.
Does anyone have the same observation?
