Except something like 60% of sleep apnea sufferers in the US will never get diagnosed. I used to be one of those people and its only after I switched doctors out of desperation that I was diagnosed.

So its hard to tell people to just sleep better if they have a disease, the same way its hard to tell depressed people to just feel better or to think positively. As a society I don't think we fully understand the effects of sleep, sleep diseases, etc. I wish there was some well funded organization pushing this information out. Instead, we're pressured from an early age to stay up late to finish things, get up early for work/school (why does the work/school day start at 8?) and be sleep deprived to only catch up on the weekend. We're also beaming bright lights from our tablets and phones into our eyes all the time, especially around bedtime, and making many of these issues worse.

Sleep is a complex issue. I'm not even sure how we can begin to address it from a public policy perspective. I think western capitalist life will always lead to sleep deprived people. We value activities, productivity, etc over rest and downtime.
