Great article. It occurs to me that after "exercise" I feel better, positive, ready to do more. The release of endocanabinoids, changes in cortisol, and endocrine hormones, plus all the changes that no one knows about, have the effect of placebo (jmho) against depression, pain, stress, etc. Like I said in the last post, do it for it's fun aspect, and feels good, rather than having to work out
This looks like an awesome and theory-heavy review! I will be sure to read it at my weekly beach break tomorrow.
Skimming it, I already read the part about IgA depletion. By coincidence I had just finished a 70 minute swimming session (non-continuous) so I have spent the rest of this evening in hypochondriac mode, obsessing over whether my throat feels scratchy, haha.
I have theories on this subject, naturally. Even though wouldn’t say it’s necessary to explain immune suppression from an evolutionary lens - it could just be a bug in the hardware - it’s definitely possible that it confers fitness to “lower the [innate] defenses” when not otherwise ill/weak (which usually precludes exertion) in order to court infection and generation of adaptive immunity. It is the host’s way of “feigning vulnerability” to microbes.
