And by the way, and as I said, that paper, there are some aspects that you can sort of discuss, but it has been replicated.

We see increased rates of hospitalization after that one hour of lost sleep in the spring.

There are higher rates of car accidents on the road after one hour of lost sleep.

We also see higher rates of suicide after one hour of lost sleep during the spring time change.

We even see, this is great data.

They looked at the sentencing of federal judges in the United States.

And because it's the federal system, the government system, all of those things are cataloged and well-documented.

So you have a huge database.

And they went back.

And what they found is that in the spring, when we all lose that one hour of sleep opportunity,

those judges doled out harshest federal sentencing in the day after they had lost one hour of sleep because their emotional and mood states were impaired.

And we'll speak about this in a later episode too.

So if you are up for sentencing, please try to avoid that spring time changes as best you can.

Go for the fall date if it's possible.

So that's your cardiovascular system.

I could also tell you that it goes all the way down into the cellular and molecular state of your body.

And I'm trying to do this to impress the fundamental importance of sleep.

There was a wonderful study done by my colleagues at the University of Surrey back in the UK, led by Dirk-Jan Dijk.

And what they demonstrated was that if you take healthy individuals, and everyone is going to act as their own control,

and you limit them to six hours of sleep for one week versus allowing them to sleep at least eight and a half hours or more time in bed.
