Dr. Rhonda Patrick

That was phenomenal.

Thank you for that explanation.

A couple of follow-up questions.

So one,

what you're just talking about, you know, the immune surveillance.

And I'm wondering, so I've read some studies about exercise, and these are normal, healthy people.

And, you know, for a long time, it was thought like, oh, if you're sick, if you have a respiratory illness, you should not exercise.

Because some studies that were done showed

found that exercise acutely lowered the number of circulating T cells in the bloodstream, in the vascular system.

But then subsequent studies were done and found that actually those circulating T cells were going somewhere.

They're actually going to the lungs.

So they're immobilizing, going to the lungs to help fight off pathogens, causing the respiratory illness.

Does exercise affect the immune cells like the cytotoxic T lymphocytes or the natural killer T cells immobilization to go to the site of the tumor as well as surveilling in the vascular system?

And most people aren't out there running marathons.

So it seems kind of silly to be so concerned about immunosuppression when a very small percentage of people are overtraining in that regard, right?

My second question is, you were talking about the shearing forces of increasing blood flow and that can kill these circulating tumor cells.

There's a variety of ways you can increase blood flow through various forms of exercise.

So for example, aerobic exercise, it's on a continuum, right?

The higher the intensity you go, the stronger the sort of push of blood flow, you know, cleaning out the system.

Resistance training.
