The majority of posts show high curiosity about the subject, often referencing specific studies, mechanisms, and potential health benefits.

EngagementModerate engagement

Users engage by sharing related research, personal experiences, and scientific opinions, suggesting a moderate depth of involvement.

ImpactModerate impact

Among the comments, there is a recognition that the findings could have implications for health practices and scientific understanding, though not overwhelmingly revolutionary.

Abstract in brief

  • This study investigated how cold exposure affects the immune system in humans and whether pre-treatments like heating or exercise influence this response, finding that cold exposure generally stimulates immune activity, such as increasing white blood cells and natural killer cells.
  • The research found that exercise in cold water (18°C) before cold exposure enhanced immune responses more than passive heating, suggesting physical activity can boost immunity during cold stress, especially when core temperature is maintained with thermal clamping.
  • The immune changes observed, including increased cytokines and immune cells, may be driven by heightened norepinephrine levels, which are affected by initial body temperature and pre-treatment methods, highlighting how the body's stress response modulates immunity in cold conditions.]

Furthermore, cold exposure may increase the numbers of white blood cells, including cytotoxic T lymphocytes, a specialized type of immune cell that can kill cancer cells. https://t.co/JS3WQpyMna

@Madam_Mito Interesting, thanks! Also funny, because I just read an older paper a few days ago saying IL-6 goes up, not down, after cold exposure. The question would be the long term effects? https://t.co/go0LsYuNqj

@DBelardoMD i don't know much about it but I had this convo recently with my physio, so I did googling. My antivax "natural" neighbour sends her kids out in the snow each morning so that doesn't exactly sell it for me But there's this, brrrrr

@djschuett @JonBLivesHere @thecheckdown @packers https://t.co/LIPfP59WsW. Maybe not directly but I think you'll agree cold temperatures especially if extreme can lead to stress to the body system, - effect on immune system. E.g in cases of hypothermia or can trigger conditions like CAD

7/9 Hyperthermia combined with sudden cooling down mobilizes your first response immune system cells that are especially important because this virus is suppressing these. This is basically sauna (koos "karastamisega") https://t.co/CQVvkDHyPO #COVID19

Looks like a score for cold exposure. It increases the innate immune response. @Iceman_Hof check out this paper! https://t.co/5u2Y3jNEu4 #wimhofmethod #cold #health

@Guillamon_ @svqcity @PauMatalap Sobre el tema de la respuesta inmune es interesante este estudio, si es cierto que añaden el componente del ejercicio con la exposición al frío, pero parece ser que provoca una aumento de la respuesta inmune. https://t.co/0VA6NpnnYC
