In Finland we have old saying: "If liquor, tar and sauna won’t help, an illness is fatal"
[−] pimeys 40d ago
I would say booze rather than liquor. Liquor sounds too fancy.

It's call alcohol

Is it true that new houses are constructed/architectured as "sauna first" and then everything else is planned around the sauna?

or is that just an urban legend claim?

[−] silvertaza 40d ago
Not around the sauna per se, but sauna is often built first because it serves as a place to live while you're building the house!
[−] mesrik 40d ago
Yes, that it was especially rural environments and not having much options otherwise to live around while building.

Sauna that was built then wasn't just one hot room, but it also had at minimum small changing room dressing/undressing, relaxing between turns in steam room. Also if it was first building made then adding also lounge which served as living space with beds and cooking stove while building house was common. With sauna you had place to stay warm first winter, able to get warm water, wash clothes, yourselves and even a give birth old times. Building sauna first made lot of sense.

These days sauna for home builders is more about getting sauna somewhere in that floorplan where works well for the intended users of that house.

wouldn't a kitchen accomplish that goal better?

Due to lack of running water in those times (and still in many cottages) cooking is done above a fire, water is brought from the lake. A kitchen won't serve you well if you're just trying to get through a long winter of -30c.

The sauna provides heating.

Average yearly temperature in Finland is reported as 6.5 Celsius

While it's true something like 90% of the accomodation have a sauna it's not like everything is planned around it. It's more like that it's the ONLY well soundproofed space, with nice atmosphere, that makes life enjoyable when your neighbors suck.

I have no idea if that claim is true, but what I did love about visiting Finland was the even the small apartment I rented had a sauna in it! It seems like it's a non-negotiable for even the smallest accommodations.
[−] weberer 40d ago
The cheaper apartments tend to not have private saunas built into the bathroom, but most apartment complexes at least have a shared sauna on the top floor. Residents can book a block of personal time in advance.
[−] nextos 40d ago
Even small brand new apartments tend to have their own sauna, which is quite impressive.

The tar ointment I bought in Mariehamn is fantastic for healing small infected cuts and bruises. Highly recommend.
[−] brightball 40d ago
Tar?

Checked life expectancy in Finland: I guess you use booze to offset the positive effects of sauna :)
[−] amelius 40d ago
Are there any scientific results showing that this helps?
[−] cue_the_strings 40d ago
All of these studies are always performed by Finns (or SE / DK / NO + maybe Russia).

I'd love to see this (and other sauna studies) replicated by someone somewhere to the south or hotter climates in general (southern Europe, Africa, hotter parts of Asia and the Americas).

>mitigate the adverse effects of low socioeconomic status

Makes me wonder how much of it is Sauna, vs just the luxury of having the time to go do nothing for ~30 minutes.

[−] moltar 40d ago
Anecdotal evidence. But since I started doing sauna regularly (once a week) I started to get sick less. I’m talking colds or flues. And the ones I did catch were much milder. Even with sick family members around I’m not catching it as often.

> A total of 51 adults (...) were exposed to a 30-minute session of acute FSB at a temperature of + 73°C

Woah, that seems like a lot for me. I can usually stand maybe 60ºC for like 10 maybe 15 min. I don't think I'd be able to stand 30 min under 73ºC.

[−] bilsbie 40d ago
I’ve always wondered if it raises internal body temperature? Is it basically an induced fever?
[−] hbarka 40d ago
I’m not sure if I want a response of cytokine storms. MCAS is what comes to mind.

Back in Eastern Europe I frequently visited public "sauna" with my parents. It included jumping into freezing water after three heat sessions and the only thing you feel is just tingling in your skin. During those years all my respiratory illnesses were very brief and never affected lower areas (like bronchitis). The very first year I've emigrated I've got pneumonia and needed antibiotics twice during the cold season. The doctor told me it's just different viruses and I didn't have immunity for those (which is ridiculous considering globalization and I wasn't in an isolated tribe before).

For my parents though I think it was net health negative as public sauna was always accompanied with a lot of alcohol.

The thing about sauna I love the most is rare moment of absolute clarity after hot/cold cycle. I rarely can think so clearly, even if it's only for ten minutes, than after putting my body to stress by sauna heat.

Weirdly I never saw any explanation.

[−] ekropotin 40d ago
Cold showers - good for immune system. Heat expose - good as well. I guess what doesn’t kills us - makes us stronger is true after all.
[−] carlosjobim 40d ago
Sauna is the perfect activity to add to most people's everyday routine. It is 30-60 minutes of relaxation for the body and mind, which nicely fill in the slot between dinner and bedtime, instead of TV/Netflix or doom scrolling in the sofa.

Sample size is tiny fwiw.

I have been searching for benefits associated with hot yoga as well, but the area is very underexplored as far as i can tell.

Why do Hongkongers (no sauna culture) and Japanese have higher life expectancy than Finns?
[−] geekraver 39d ago
What about non-Finnish sauna heat? Or do I have to go to Finland?
[−] ascii0eks84 40d ago
Sauna basically is the "hot winter" simulator.

Does a long hot bath do the same?
