Great, even; wonderful, sometimes, when a hammock or a seascape is involved.

People say, I took a three-hour nap… Well, thats not a nap.

A nap happens when you fall under.

The term itself was coined byAndrew Huberman, a neuroscientist and Stanford professor.

Huberman has evangelized NSDR far and wide.

Huberman calls optimization techniques like NSDR protocols, shading his speech with a militant flavor of masculinity.

Holiday-Bell likes to pair the two: She may doa guided meditationor short yoga nidra practice to fall asleep.

It can improve stress and anxiety, cognitive functioning, mood, she adds.

What kind of people, I wonder?

The earliest yoga sessions in human history would regularly end with short intervals of rest.

At a [yoga] studio, if the floor is uncomfortable, people get restless, Mittra says.

Its merging rest with intention, she says.

Dr. Holliday-Bell maintains a simpler practice.

If given 30 minutes and the choice of a nap or NSDR session, shell take the former.

But my favorite protocol was the state of concentration Mittra described instead.

Lets compare our body to a telescope.

During the first step, the first level, we are repairing the telescope, he explains.

It takes a tremendous effort, Mittra says, not to disappear completely.

A tremendous effort begs the question: Why not take a nap?

Dr. Holiday-Bell, for her part, is a power napper.

But I do think there are more benefits to going through at least some of the sleep stages.

All you need is between 20 and 45 minutes and a dark room.
