Just a reminder. If you donate blood you can chip away at these forever chemicals. There's almost no downside.

There are other potential health upsides too. Regular blood donation has been found to be correlated with healthier blood pressure, and in men it can also prevent you from accumulating too much iron in your body, which can prevent heart problems down the line.

Curious, do you have a source for this? Are PFAS primarily concentrated in the bloodstream?

  I'm not sure if it's concentrated in blood or not but as I understand it it's mostly protein bound which means it probably moves into and out of tissues easily but not out the kidneys or into stool. https://www.wbur.org/news/2023/02/16/pfas-biology-blood-new-hampshire https://www.wbur.org/news/2023/02/16/pfas-biology-blood-new-... Someone else's already replied with the Australian fire fighter study which shows that blood levels fall with donation. If movement isn't free into and out of the "compartments" then it's possible end organ damage continues unabated even as blood levels dilute. But it seems likely that donating does reduce concentrations in organs as the PFAS move back into blood.

The downside is that it's a pain to donate. Every place I've found is 8-5, which is when I'm working. Also I have small veins, so it's gonna hurt.

  Yes and very intrusive questions when you do donate. The first time is more of a faff to organise, but they do harass you for travel and sexual history each time. I think subsequent donations are easier but that might be because O neg and men's blood is always in demand (which is what I have).
