Trying to understand Blood Flow and Detox better

So I have a hypothesis but I can't find enough information on the inter webs to build on this hypothesis.

So thought I would share it here and get people's input, for this forum has a high concentration of well above average science, health, and biology savvy people.

So with all the herbs, vitamins, and pharmaceuticals that we lymies take on a daily basis, how does exercise interact with this?

What I mean is, if exercise is an effective means of detoxing, flushing/filtering, and increasing blood flow and circulation, can it also mean that exercise filters and flushes out our herbs and meds much quicker and how that isn't necessarily a good thing?

If I take an herb, and this herb has a half life of 4 or 12 or 24 hours in our system, will exercise actually filter and flush out the herb or med (especially those that enter and work in the blood stream) quicker?

I ask because I've taken meds before on the same day I had a good work out and I suspect those meds worked less well (I think, it seemed, it felt like). But I don't know if this is actually scientifically true or it just "seemed" that way.

Thank you in advance for your input.

Thank you for the reply. But I'm wondering if even a moderately healthy level of exercise actually flushes out herbs and medication so that it's actually not as effective as it could be, because it doesn't stay in a person's system as long as it was intended to for same
desirable effect.

Assuming the premise is even true in the first place, which is what I'm trying to figure out.

There's all kinds of claims that exercises can detox and flush out all these "bad" things, well how does the body know what is "bad" and what are other things that are not "bad" that we are purposely putting in our blood stream?

I like astroman's answer 😊

I'm no scientist, dacarte, but I would think there are only 3 ways to "flush out" meds, etc - pee, poo, sweat. I've seen warnings on Rx leaflets about meds building up excessively in those with liver or kidney impairments, so we know that if liver and kidneys are not working optimally, it can take longer for the body to "flush out" the meds. I've never seen any warnings for those who cannot sweat properly.

While that could be due to the ignorance of conventional doctors about sweating, it could also be that sweating has little impact on removing meds from the body. Since exercise would affect sweating and probably increase urination since you would be drinking more but would not likely affect bowel transit, I would think exercise would have minimal impact on the elimination time.

This past week, I had 3 good days in a row after months of feeling awful, and I totally overdid it physically. I've now felt like crap again for the past 2 days. I haven't changed anything else. I don't fully understand how and why, but maybe the physical exertion and sun/heat exposure either killed something too fast or increased the circulation of toxins, which my poor body can't seem to ditch.
