There's actually a trick to avoid

the daytime, uh, the afternoon crash.

It's not a trick, it's biology.

But caffeine is an adenine antagonist.

It basically, as the longer

you're awake, adenosine, or Matt

Walker was say adenosine Aden.

Adenosine builds up in your bloodstream.

It's what makes you feel fatigued.

Caffeine essentially blocks the

adenosine receptor, but then when

caffeine wears off, the adenine that's

still around binds to that receptor

and you crash, you feel really sleepy.

So one thing that you.

When you wake up in the morning,

don't ingest caffeine for the

first 90 minutes or so, like really

push that off so that the adenine

and adenine receptor interactions

can all take place and dissipate.

Then you drink caffeine, and what

you'll find is that if normally you

would crash around two or three in the

afternoon, you don't experience that

crash anymore because the caffeine

wears off, but there isn't a lot of

adenosine there to bind the receptor.
