Maybe you will, but many athletes don't.

Even at the very elite level, they are not sleeping well right before competition.

But if you've banked good sleep up before, like if you're already off balance and barely keeping on two feet and someone bumps into you, you're going to fall over.

But if you're well-planted,

and someone bumps into you, you can recover pretty well.

So one to two nights of short sleep does not dramatically impair performance.

It might stress you out and you might psych yourself out.

That might impair your performance.

But if you're coming from a place of strength, one or two nights dropping your sleep from eight down to like six or five hours, you might have some cognitive impairment, but it's gonna be quite minor.

A week out, it's going to be very pronounced.

It builds.

It's cumulative.

But one or two nights isn't going to be that big of a deal if you're coming from a place of strength.

Yes.

A week or two.

Yeah.

Right.

It's not about the night before.

Come in with confidence.

It's like with nutrition.
