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.

It tells us something about dreaming above and beyond sleep that is predictive of our mental health.

I think most people can probably tell you to a degree, am I getting the sleep that I need? And you can ask at least one or two questions to answer that. If your alarm didn't go off tomorrow morning, would you sleep past your alarm? If the answer is yes, you're not done with sleep yet. You're not satiated.

Another good example would be how much are you sleeping during a working week and how much are you sleeping at a weekend? And this is not a perfect test for a number of different reasons, but if you're sleeping more at the weekend than you are during the week,

then what I know is that you have the capacity to generate more sleep and you have a higher, you have a sleep need that is higher than that which you are giving yourself the opportunity to get during the week. So it's not as though you just are someone who actually needs six hours of sleep because at the weekend, you get more sleep than you would do during the week.

So I think the first thing is ask yourself some honest questions. Am I getting enough sleep? The next question then is to say, even if the quantity of sleep I'm getting is sufficient, maybe I still do not feel restored or refreshed by my sleep the next day. And that comes on to quality over quantity. It's not just about how much sleep you're getting.
