The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
and that needs to be cleared out, and as we age, our heart gets less efficient at clearing out that waste. Cardiovascular exercise increases literally the number of lymphatic vessels that allow the drainage of those toxins away from the heart, which greatly supports the cells of the heart.
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.
One is "Lymphangiogenesis contributes to exercise-induced physiological cardiac growth." The actual growth of the heart is enabled by the development of these new lymph vessels to the heart that are induced by exercise. So that's really cool, and in addition, I hate to break it to you, but for all of us, your heart gets less healthy as you age, even if you stay very healthy as you age. In part, that's due to inflammation from the buildup of waste products within the heart. There are other reasons for this, too, but it has now been demonstrated, and here I'm quoting the title of this paper, again, I'll put a link to it in the show note captions, "Exercise-induced cardiac lymphatic remodeling mitigates inflammation in the aging heart."
