Not great for your health, long-term - as you'd be breathing in unheated, cold air for excessive periods -
"Cold air inflames lungs and inhibits circulation, increasing the risk of respiratory conditions, such as asthma attacks or symptoms, worsening of chronic obstructive pulmonary disease (COPD), and infection. Cold also induces vasoconstriction, which causes stress to the circulatory system (198) that can lead to cardiovascular effects, including ischaemic heart disease (IHD), coronary heart disease, strokes, subarachnoid haemorrhage and death (198–206). Most of the evidence for the impact of cold on health comes from studies connecting outdoor temperatures to health outcomes. For example, cold spells are associated with increased mortality and respiratory and cardiovascular morbidity (207), and mortality and morbidity rates in countries with cold and temperate climates are higher in winter than in summer (208)."

- phendrenad2 2y agoWe need to do more research into this, honestly. The biggest factor - time - isn't accounted for (I.E., do you eventually acclimate to colder temperatures, nullifying all of the bad effects these studies find in the aggregate).
- dp-hackernews 2y agoJust think Inuit or Aboriginal - both living in environments of opposing extremes, surviving just fine for many, many years...
- _joel 2y agoYex, they adapted over millenia. I don't see what relevance this is to this particular issue though.
- phendrenad2 2y agoDid they really adapt over millennia? There's a lot of relevance if you keep your eyes open.
- _joel 2y agoYes, physological changes that they have don't appear overnight. https://library.ucdavis.edu/wp-content/uploads/2022/07/Lang-Prize-2022-David-Vo-Project.pdf https://library.ucdavis.edu/wp-content/uploads/2022/07/Lang-...
- phendrenad2 2y agoDid any of the physiological changes appear overnight?
- _yb2s 2y agoI’m pretty skeptical of this because it seems to conflict with common sense and personal experience but I’ll look a bit more. I wonder to what degree they controlled for health effects of short days, less sunlight, more time indoors, increased infectious disease in cold months, poverty, etc. I doubt they are finding people that do a lot of outdoor winter sports for example have increased health problems vs people that just sit inside.
- bgnn 2y agothis 1 study says so? I bet you can find a study claiming the exact opposite.
- _joel 2y agoGo on then
- m463 2y agoI've read about saunas, and studies were saying people who spent 19 minutes, 4-7 days a week in a 174F sauna had a 66% less chance of dying from all causes. And then marketing people tried conflating IR saunas with conventional saunas, which nobody has studied and might not have the same efficacy. I don't know either but I suspect hot air, especially in the lungs is a big part of the mechanism.
