Huberman Lab · Accelerate Learning & Increase Cognitive Capacity | Dr. Tommy Wood · 20 Jul 2026 podcast

So you're definitely augmenting some of these processes of neuroplasticity.

Some of that's going to be related to the catecholamines and other things that get released as arousal increases.

But we also know that different types of exercise have different effects on different parts of the brain.

So yes, I think some of just the general process of moving your body

and exerting effort definitely increases arousal, definitely improves cognitive function, improves learning, as long as it's not truly exhaustive exercise.

Anybody who's done some terrible CrossFit WOD, or I used to be a rower, we used to do a 2K test on the rowing machine.

You do a 2K test on the rowing machine, your brain does not work afterwards.

It's like a six minute flat out VO2 max level of exertion.

Especially if you want to perform hard, cognitive work directly afterwards.

Sometimes if you're trying to really push performance or adaptation, it's worth...

digging into that hole.

But it really just depends on what you want to be able to do directly afterwards.

Yeah, I think that a lot of it's going to be based on what your current capacity is, right, as with everything.

So if you want to do some – you've got some learning to do, you've got an exam, you want to do some hard, progressive work at whatever it is, writing a presentation, analyzing data, reading papers, writing a book, then doing some kind of workout that's probably below –

you're kind of typical or below what you would do when you're really sort of pushing the envelope.

I think that when you look at meta-analyses of exercise and then cognitive function immediately afterwards,

the protocol that has like the best evidence for it is like a 20 to 30 minute jog, right?

So like, that's the kind of level of activity that really seems to sort of like support all those general processes of plasticity and learning.

I mean, you'll definitely get some, right?

And like cortisol too, right?
