I understand that sleep is a variable worth studying and improving and that somebody on the edge of the bubble might be pushed over that edge if they also had to simultaneously deal with a lack of good sleep. But why are so many people getting to that edge? People have been dealing with not enough sleep for a very long time and we didn't see some current day problems in the past. To me, this seems to show that a lack of sleep is probably not anywhere close to the biggest variable when it comes to the major mental health challenges that the current generation faces. Theory. Sleep might be emphasized here by officialdom because it's one of the few additional variables that's politically correct enough to start to discuss and tackle. They can try and tackle sleep because no school administrator/media entity/politician is going to get cancelled (yet) for trying to ensure that the students get enough sleep.
