They just measured the temperature of someone's feet and they looked at how quickly they fell asleep and when they fell asleep.

Sure enough, the warmer your feet, the faster you fell asleep.

Why?

Because the warmness reflects the blood dilation and the pumping out of the blood to the periphery.

And then they did it in rats where they started to warm the paws of the rats and the rats fell asleep more quickly.

And I love this notion of, again, we don't do animal warfare.

I love the notion of wrapping a beautiful little rat up in cotton wool and warming its feet with this pad and it's just blissed out and then poof, he's gone.

After all, she, I respect their privacy.

So that was the early evidence.

That then led to a series of manipulation studies.

The most notable is brilliant.

It comes from a colleague in the Netherlands, Oes van Sumeren and his group.

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.
