It's like going to China or going to Europe is very, from the West Coast US anyway, is very different than going from New York to LA.

New York to LA, it's a few hours.

And you'll adjust within a couple days.

You could adjust probably within two to three days.

You're probably fine.

Traveling that far, the circadian literature would say that it takes about an hour per day to adjust.

Obviously, faster going west, a little slower going east.

But when you're 10 to 15 time zones away, what is day five?

four versus day 12 look like?

You're not going to slowly adjust.

It's going to be in, it's going to be jerky.

So what I would say is when you get on that plane,

think of yourself as having had maybe just a very short day.

I like sleep depriving myself a little bit before these long flights.

Um, and you get on the plane.

I like to try and schedule my flights so that it would be great if I traveling to Europe, it's easier to do this where you, where you time the flight so that it lands in the morning local time.

So you're taking off in the afternoon from the U S and it might be three, four or five, six in the afternoon, but you're landing at 10 AM local time.

So as soon as I get on that plane, I'm like, okay, it's nighttime.

I have this eight hour, eight, nine hour flight.

Um, this is going, this is my night.
