They created essentially what was a wet... Think about a wetsuit.

But that wetsuit is covered with all of these thin tubes, almost like veins that go all over the suit to all territories of your body.

And then what they would be able to do is perfuse water, warm water or hot water, exquisitely to different parts of the brain or the body.

Cool.

Amazing.

Yeah.

No pun intended.

Thank you.

So what they did was then they started to manipulate these peripheral regions sort of.

And sure enough, when they did this, they were able to have individuals fall asleep 25% faster.

And these were healthy individuals who are normally sleeping within a very natural, quick period of time.

but they were able to lop off 25% of that time simply by warming these certain parts of the brain to lift the blood away from the core of the body.

And by doing that, they accelerated the temperature core deceleration and therefore increased or accelerated the speed with which sleep arrived to those individuals.

Sleep appeared with much greater alacrity than it would have done otherwise, even though it was quick anyway.

So them not being satisfied with that, they moved on to the deep sleep trigger zone.

And this isn't, you need to stay cool to stay asleep.

And here now, they started to just continue to cool the core, the central aspects of the body.

what they were able to do is increase the amount of deep sleep by somewhere between 25 to, look at some of the data, almost 40 minutes, they were able to boost the amount of deep sleep with the thermal manipulation.

And when they were measuring the electrical brainwaves and they decompose those brainwaves, even the power and the electrical quality of those slow waves was increased, very impressive too.

Next, not being satisfied with that, they turned to older adults for the reasons that we've just described.
