what is some crazy sauna fact?

In Finland sometimes we take advantage of the heat and we cook sausages on our sauna stove by wrapping them in aluminum foil and placing them on the hot rocks. You can still take a sauna normally and afterwards you have a cooked sausage to eat!

In Korea they cook soy-sauce-marinated eggs

going to give that a try

Our relatives always had a nice big piece of meat in there when we visited. Ofcourse they had at least three different saunas on the yard. The smoky sauna was mostly used for the cooking.

seems like you and your relatives had a good time ;)

Off-topic but I've been curious: how well do phones handle saunas? I thought the heat and moisture would pretty much be the worst environment for electronics. Is that not the case?

For some real numbers: I have a barrel sauna with a Harvia. I take my phone in all the time. One level only. Where my head is, is where the thermostat is. When the temp says 170F the phone which is maybe a half meter below my head will almost never overheat. At 190F it will overheat eventually. Usually around 15 minutes or so. The higher I hold the phone and the less I insulate it the faster it overheats. “Overheat”…

There may be no risk to the phone electronics themselves, but you are abusing the battery and increasing the risk of failure though bulging and thermal runaway.

I would personally not call regularly exposing lithium ion cells to 170+ degrees F “safe”.

Why do you think those protections are there?

I prefer the steam room at my gym over the sauna because it's much less crowded. I'm convinced the sauna gets more traffic in part because you can use your phone in the less humid environment.

I don't know how phones are tolerated in a sauna where people are naked. Or are people naked in gym saunas over there?

The sauna design rabbit hole is a very deep one. If anyone is interested in more information about sauna design in general, Trumpkin's Notes are by far the most referred to guide out there. [1] There are also new products [2] which help improve saunas which are not ideally designed or where there are constraints (ceiling height mostly) to deal with. 1: https://localmile.org/trumpkins-notes-on-building-a-sauna/ 2: htt…

Thanks for the links. I built my own super cheap (under $100) electric sauna, though I would not recommend it for anyone else to copy. It's lasted me about 4 years now though with about every-other-day-usage without burning down the house so... that's nice. I'll see if I can apply any of Trumpkin's Notes to my jank build [0] [0] https://news.ycombinator.com/item?id=28495062

Thanks for the link. Have recently been looking into saunas. So do you still strap your phone onto a block of ice ?

I’m looking to spend about 1500, if you were to upgrade your situation while having a slightly large shoe string budget, any leads ?

I find it so annoying that you can’t just buy a high quality kit in the USA. It makes no sense to have to design a 1of sauna every time someone wants to build one. Plus sourcing your own material is annoying as well.

A sauna is a small, enclosed area with an extremely high moisture content that is only used for short periods of time. The expense of a heat recovery ventilator that could work with this extreme level of moisture wouldn’t even come close to recouping any potential cost savings. The combination of ventilation and heat source along with water poured on to the source is a way to regulate and adjust the temperature. The…

Dry saunas are a thing also. My gym sauna is dry except for the humidity provided by the sweating people sitting in it. They prohibit putting water on the rocks.

Sure but that has very little to do with the Finnish designs of saunas.

re: ice, yes, though I know Trumpkin and other traditionalists would be appalled. I do (occasionally) practice meditation - but I don't ever want to do it in a sauna.

I have no plans on upgrading so I haven't put any thought into it. A causal search revealed this in your price range [0] but I don't know anything about it. Don't forget that you'll likely need to pay for an electrician to upgrade your home circuit.

For me if I were to upgrade, it would be first be to get a better heater. The thermal foil + sleeping bag is surprisingly effective, though obviously I can't practice Trumpkin's advice on doing hot-cold-hot-cold-hot cycles easily without a door. It currently takes about 10-15m to get up to temp. So if you were on a smaller shoestring budget, I do think my thermal foil + sleeping bag build would save you a _lot_ of money on wood. I built a small (4x4x4) wood cube to sit in (you can see its base in the photo) but it leaked so much air that my DIY heater couldn't keep up. So I went with the thermal foil, which has all kinds of advantages... but it's certainly an eyesore :) A more powerful heater (with the appropriate house circuit) would make a small DIY wood box viable again. I think I _could_ recommend my jank build for others if they used a heater that wasn't DIY.

I still wonder when my DIY heater is going to kill me. I've since covered it with ceramic and wood so I'm no longer worried about 3d degree burns from fainting or whatever. And I use a GFCI outlet so any shock won't kill me. And I literally unplug it when not in use so it won't do anything unexpected. My thermal foil is _flammable_ though... which I found out when my heater started sparking. A better heater won't do that - but still...

Honestly, depending on your situation, it might just be better to save for a "real" sauna. For me time and money are currently at a premium, so I likely won't upgrade for years.

45 year engineer, not 45 year old engineer. It's not about their age but their experience. The relevance is that someone spent 45 years, as a trained adult engineer no less, not 45 years merely breathing, aware of a problem and only after than much experience, solved it. It would also be interesting if they had been a 1 year engineer or not an engineer at all, just for different reasons.

In what part of the world is it typical to say "45 year engineer"? I'm an engineer in the western US, and would say "an engineer with 45 years of experience". I interact with lotsa international english; this one is new

The words are the words. No one else can help the fact that you interpret words that weren't either written or implied.

A 10 year smoker may or may not also be a 10 year old smoker, but probably not.

A 6 month project may or may not also be a 6 month old project. Etc etc.
