Roughly 40% of adults experience frequent daytime sleepiness from poor sleep, and silent shifts in breathing are an overlooked cause. Introducing the Sleep Breathing Quality metric from Google Health. Using the optical and motion sensors on your watch or tracker, this feature monitors minute-by-minute blood oxygen variations while you rest to calculate your time spent in optimal breathing—validated against clinical polysomnography (PSG) sleep studies. Track your daily metrics and view monthly trends in the Google Health app to spot patterns and adjust lifestyle habits like sleep position, bedroom conditions, and evening routines.
