I never found a reason BUT my personal opinion is: Probably putting some "stress" on the cells is beneficial, is like forcing them to work a little once in a while instead of letting them function in the "just survive" mode. Maybe blood circulation? It may clean toxins from where the blood may flow slower? That's my headcanon

Whatever science I read on this seems to indicate that the exercise induces a high amount of oxidative molecule release in your cells. That should be bad for the body because that results in oxidative damage. But of course we've evolved mechanisms to compensate. For that, there's a corresponding release of antioxidants and cellular repair to deal with the oxidation events of exercise. Exercise in general raises your immune system as well. Your immune system cleans up a lot of rogue mutation cells. It may also be the physical activity increases massive amounts of blood flow through your entire system and helps at a macro level with this cleanup of deviant cells. But I'm not an oncologist nor am I a physiological biologist.

Hearing the evolutionary anthropologist Herman Pontzer talk about this was really eye-opening for me: https://www.msnbc.com/msnbc-podcast/examining-energy-evolution-herman-pontzer-podcast-transcript-n1270125 https://www.msnbc.com/msnbc-podcast/examining-energy-evoluti... "[Y]ou can think about all these processes as competing for calories over the course of the day. And normally, low priority things like having a really high inflammation response or having a high stress response, those get tamped down in a highly active population like we've all evolved in. But now, you move to these weird zoos that we've built ourselves, where you don't have to be active, food's available all over the place, energy supply is really easy. And now, these low priority activities which used to probably only happen very occasionally in the past, in the deep past, now are happening all the time, chronically, at these super high levels, and it's actually really bad for you."

  That's a good read. But one of the processes competing for calories is the immune system. > If you take somebody who is really sedentary and you get them exercising, what happens? Things like inflammation, which is your immune system being overactive, goes down. [Also cortisol level when under stress, and reproductive hormone levels, go down.] So that puts a small hole in the "exercise helps the immune system clear up cancer" theory. Maybe it in fact stops the immune system causing cancer. Or maybe it does both things, since biology is messy and the immune system might have multiple energy budgets for all I know.

  Oh wow, super useful link. So in a way my simplified assumption was more or less right, my ego grew a little bit and i think that's a bad thing
