But I don't think that's the protocol you have to do.

I think it's just this process of high-intensity exercise that...

It releases a whole bunch of myokines and lactate in particular.

We know that lactate very easily gets into the brain, stimulates BDNF production as kind of part of that support of neuroplasticity or augmenting recent neuroplastic processes.

I think there's something about that, just that high intensity work that drives some of those factors that then support structure and function.

Well, I think if you want it to be sustainable for long periods of time, like I would typically say one day of high intensity work is fine, right?

Because you probably want to be doing some resistance training.

I'm doing that three days a week.

So even though his frameworks are still potentially very helpful, some of it we can blame on Hans Selye and his general adaptation response.

The original idea that if you were chronically stressed, it would lead to true exhaustion of all your physiological systems, because that was the final phase of his general adaptation response.

People have conflated...

acute stresses versus chronic stresses.

And yes, we know chronic stress, be they psychological, physical, increased allostatic load, increased metabolic disease, inflammation, blood sugar dysregulation, insulin resistance, significantly associated with heart disease, dementia, all these kinds of things, right?

So we know that these chronic stresses can be really detrimental to our health.

But

we've kind of conflated that like any stress is bad because chronic stress is bad.

But the way that I think about it or I try and talk about it is that actually the stress response, and this is as kind of Selye originally described it, is stress drives adaptation.

He called it general adaptation syndrome or the general adaptation response because what stress is, is your body acknowledging that

you need to respond to some external stimulus, right?

And so stress diverts resources so that you can then adapt to that stimulus, be they physical, cognitive, neurological, right?
