Low oxygen levels during sleep?

I have purchased a new smartwatch and lately, it has been tracking my oxygen levels while I sleep. I notice that my oxygen level drops to 85%. It happens just for a brief moment but I just want to make sure if this is something I should be concerned about.

Brief drops could be due to suboptimal signal but if persistent and especially if observed during sleep the following morning, consider Sleep Apnea. In that situation consider getting overnight pulse oximetry or Home Sleep Study and establishing care with a sleep specialist.
