Apple watch 5 series measuring heart rate even when the watch is on the table

I bought my apple watch 5 series last week and i found out that the watch measuring heart rate even when the watch is on the table or when it laying on the bed while i'm sleep.


Is it normal or should I take it to a service to fix it ?

I think i found out what caused it to measure heart beat while not wearing the watch...

it was set to unlock when unlocking iPhone in the settings, so probably i unlock the phone at night and the watch stays unlock during the night.


the only thing i don't understand is why and how it can measure/detect heart beat if it's not on the wrist.
