@svenscholz Can we stop with this?
There is theory - and science - and then there's just living in thick, hot soup for 6 months a year.
And they're fundamentally different things. Which sounds annoying because theory should be absolutely the truth.
Lived experience just exceeds expectations. That's all I'm saying.
@Remittancegirl @svenscholz yeah, that's extreme.
BTW, do fans still help at those temperatures and humidities?
I'm always surprised how big of a difference sitting next to a fan makes in the somewhat less extreme 35C with low humidity, maybe even a bit better (but very localized) than just AC.

@Remittancegirl > eat and drink things that trigger sweating.
Do you have any tips? I don't really know what sort of things that is?
Do you mean spicy curries or something?What do you think about eating salted stuff (e.g. peanuts) to replace salt? Is that a thing?
@ebel All I can say is that the whole of Southeast Asia eats spicy stuff and curries, and I think there is method to this madness. It makes you sweat. Same with drinking hot chai and hot tea - which seems just so nuts in the heat.
As to salt... I didn't mention it, but it's important if you're sweating.

To my northern neighbours suffering from the current heat wave.
I lived in approx 38C with 90% humidity for 20 years, and I have a few pieces of advice.
1. Don't do anything fast that you can do slow.
2. Umbrellas aren't just for rain. They work for sun, too.
3. Sweat is your friend. Drink lots of liquid, eat and drink things that trigger sweating.4. Cold showers and baths trigger your body to warm up. Room temp showers work best - and don't bother drying off.
@Remittancegirl Thanks for the advice! We're not quite there with the heat, but largely have the humidity, and luckily for now we're only looking at a few days of heat wave at a time.

@Eetschrijver Cats have very good instincts for keeping themselves cool. hehe.
@Remittancegirl They do, I'm really marveling at her.

@vriesk
Yes, absolutely. They help evaporate sweat, even if just a little, even if they're not cooling you down directly.I notice that fans really stop helping at about 40. But it never got that hot in Vietnam where I was. But when I was in Cordoba, which is very dry heat, I noticed that fans started to feel like a hair-dryer on hot at 40C. If anything, it made it feel worse.

@vriesk Actually, I think the combination of AC and a fan is really quite important. Because the cool air tends to hover at floor level, and a fan helps move it around a bit. @svenscholz

@Remittancegirl @svenscholz oh, that's interesting - I would have thought it's the opposite.

@vriesk Logically, it doesn't make sense. If it is very humid, why would a fan pushing humid air help? But every old structure in semi-equatorial countries has old ceiling fans. These people aren't stupid. They have them because they work. Even in the height of the rainy season. @svenscholz

@Remittancegirl @svenscholz yep, that makes sense. Some top-mounted AC units have this mode of pushing the air horizontally all over the ceiling, which then somewhat uniformly falls down and mixes well, and the effect is much better than just blowing it down (with the same unit).

@vriesk Yup. While it feels good at first to have the cold air blowing down on you, in the long run the whole room gets more comfortable if you have it blowing high across the ceiling and having a fan aimed at the floor to kick it back up and circulate the cold air once it falls. @svenscholz

@Remittancegirl @svenscholz Which makes me really wonder why on Earth the floor-mounted internal AC units are so popular in the US.

@Remittancegirl You can also create a simple kind of AC by placing a fan in front of wet laundry. That will make your rooms more humid, though.

@VerenaRupp What a good tip! And it dries your laundry too!
It is very good for high, dry temps.

@vriesk I know, right? Do they not understand that hot air rises?@svenscholz

@VerenaRupp @Remittancegirl I was told this only works up to a given air humidity.
In those cases Putting a bottle of frozen water in a bowl in front of a fan seems to work better and also dehumidifies the air (again, hearsay, still need to try that)…
-
@Remittancegirl No, I absolutely don't think you're lying or anything like that. 38C dry-bulb is definitely happening in many places, also the humid ones.
Also, your hot-weather advice is very sound and good.
Just that during the peak-temperature hours, the relative humidity is likely even lower than 80% even during the wettests months, as 38C with even 80% is 34.8C, still on the edge of survival for humans. Vietnam is not listed to ever get above 34C in this list: https://en.wikipedia.org/wiki/Wet-bulb_temperature#Heat_waves_with_high_humidity
Cheers. Wet-bulb temperature and how it's different from a dew point is something i learned today.

@dec_hl @VerenaRupp @Remittancegirl it should work though probably a very minimal dehumidifying effect. Condensation will form on the bottle and run down in to the bowl, just a fairly small amount because the surface area isn't very high. Still, more than nothing

@Remittancegirl @svenscholz um, well, they do have this vibe of a country that knows everything better than anyone else, don’t they.
-
Are you sure about those numbers? 38C with 90% humidity is 36.5C wet-bulb.
That is not survivable by a human and sweating does not cool one down at all in such a temperature. Also, according to Wikipedia, the highest recorded wet bulb temperature ever was 36.3C in UAE.
Come to Japan in August...

@Remittancegirl A wet flannel on the back of the neck also works wonders in this heat.
