The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
so basically what we're talking about is the lots and lots of ways that exercise improves brain health in the longterm bdnf brain plasticity stability of synapses and so forth maybe even new neurons maybe not a lot of evidence for that in humans yet frankly but maybe
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
But generally looking at this question of physical activity and brain health and probing the role of intensity there. So you know, my understanding is mainly based on talking to my colleagues, trying to read reviews of some of this research, and my sense is, you know, very well established potential mechanisms now from some of the animal studies. And the human data is certainly intriguing, but you know, that link between lactate, BDNF, absolutely there appears to be a role for intensity there in terms of higher intensities, the better in terms of, you know, potential BDNF bathing the brain, some of these outcomes associated with neurogenesis.
