I wonder if Apple Watch can detect/show signs of sleep apnea? It measures your breaths, so I theorize if you have sleep apnea, you will eventually stop breathing then wake up suddenly to breathe hard due to the lack of oxygen. So it might show as unevenly breathe rate on the watch. But I guess monitor your breathing during sleep using WiFi signals is a better solution.

It doesn't, but only because it polls relatively infrequently for biometric data. The increase in pulse or decrease in blood oxygen saturation is not likely to be captured if it lasts only a few seconds and the watch records a datapoint every few minutes to increase battery life
