Every smart watch/wearable device has some kind of sleep tracker now. Newer ones have pulse oxymeters. Even if they are inaccurate, they are making a lot of people self-conscious about their sleep. - Why is my sleep score only around 50? - Why is my HRV lower than everyone elses? - Why does my pulse ox regularly fall to the 80s? Some of these people are going to seek medical advice, and some will be prescribed CPAPs. As far was why people seem to be having sleep apnea more, I like the theory that it's related to weaker jaw muscles in proportion to our bone structure, caused by the modern diet of eating softer foods. But it's a current area of research.
