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.
There are a number of studies that have pointed to the fact that deliberate cold and cold generally can reduce inflammatory cytokines, such as IL-6, interleukin six. It can increase anti-inflammatory cytokines such as interleukin 10 and so on.
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.
we also measured the IL six in the study just to see also an inflammatory anti-inflammatory marker so I six when up and it also follows with the i 10 so that is like also very known in the literature
However, what they found was if people did deliver cold exposure repeatedly over a period of about six weeks, and by repeatedly, I mean three times per week, what they found were trends. And again, trends are not statistically significant, but trends towards increases in plasma concentrations of things like IL 6, interleukin 6 or total numbers of T lymphocytes and T helper cells and T suppressor cells and activated T and B lymphocytes, these are all immune cells and immune molecules that roughly correspond to an increase in immune system function.
This study, which we will link to in the show note captions is but one study of several other studies showing that deliberate cold exposure can increase immune system markers, especially when deliberate cold exposure is done repeatedly over time, so in this case, three times a week over a period of six weeks.
