And I've often thought, and it works both ways for health and ill health with good sleep versus bad sleep. If you've gone into one of those fancy music studios and there's that mixing deck with all of those little dials on it.

Yeah, and I look at it, oh my goodness. And you can move all of the different dials. They're all of the different systems, but you know that there's that one white dial all the way to the far left that if you move that up, all of the other dials go up with it. That to me is sleep. It is the Archimedes lever of health. So that's why when you move sleep up in the right direction,

you cascade down this whole, it's the single tide that rises all other health boats in my mind. And I think it's not my mind, it's the data.

Teens who are sleep deprived because of early school start times. Suicide. And the link between a lack of sleep and suicide now, I think that's been one of the things that has just exploded on the scene in the past five years. Certainly, I didn't have anything in the book about that because it was just nascent at the time. Now, that data is so compelling.

Insufficient sleep in teens will predict suicide ideation, meaning thinking about suicide. It will predict suicide attempts, and tragically, it will predict suicide completion. And it's not just sleep. What we're finding is that a lack of sleep will have maybe a twofold increased risk for suicidality in teens, meaning you may be twice as likely based on a cutoff of insufficient sleep.

Right. And it's not their fault because the biology, as they become adolescents forces them to have a, an appetite, a predilection for sleeping much later into the night. They're not trying to be rebellious. It's just their biology. But then early school start times have them waking up far too early.

So the one thing that gets squeezed like vice grips in the middle of the night for these teens is a sufficient night of sleep. But what we've also found is that it's not just sleep. Dreams seem to be, and bad dreams in teens, seem to be even more predictive of suicide than insufficient sleep itself. We've got no idea why.
