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.
but that's because the brown fat um has grown these more mitochondria in the cells so these small energy Fabrics that's going to activate the cells and that's going to take up glucose and fat from the fatty acids from the bloodstream to keep uh the thermogenesis up
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.
indeed when I did that I think it was just two days of being in that cold environment then I could come back on the third day and be perfectly comfortable because the brown fat had expanded um um or or added mitochondria or both and I was perfectly comfortable in that environment
so you are prepared in a way the capillaries in your skin is also will also become better at like constricting so you will have a better Shield of your body to uh prepare you for the next time so you be become better at H going into the cold water in that way so the the body makes these mechanism and changes your body in a way so you can expose yourself to the next time right
actually what you want to do is get yourself uncomfortably cold activate your brown fat and indeed when I did that I think it was just two days of being in that cold environment then I could come back on the third day and be perfectly comfortable because the brown fat had expanded
it increases the brown fat storage which I sort of see as a kind of like the oil in the candle yeah of the Furnace that is thermogenesis and that in turn leads to increased heat loss
you know we know of course it can help and it the data you know is is mixed but like incre increase Brown fat which is like mitochondrial dense fat and have it do more work and whatnot
deliberate cold exposure then leads to one feeling more comfortable at cold temperatures because you become a you know a essentially more of a furnace more more more Brown fat
I'm going to focus on increased brown atapost tissue. This is the thermogenic type of atapost tissue. We're going to talk about the effects on mood and cognition. That's like my favorite. We're going to talk about the effects on mitochondrial biogenesis, the growth of new mitochondria both in atapost tissue and what that means and also in muscle tissue and what that means.
