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 as per tips - I dunno if it's been mentioned:
1. Wet tshirt - the evaporation cools you
2. Shutter or leave curtains closed. The sun through windows adds SO much heat. It might sound counter intuitive to black out windows etc but it works
3. I usually open some of the windows, but the jury is out whether it's a good idea...you can get a breeze, but it might bring hotter air in? I tend to find in my basement flat it's better to have some air flow, it's cooler usually.

But, when I visit family in Italy, my first steep cycling climb fails (2 years in a row). Body gives up and says "no more". Then the day after (with legs that should be already tired) it's fine. Only explanation I have is that the 1st failure acts as a strong signal: body needs to adapt to the heat - right now.
I might be wrong, but it's the only explanation I have, and fits with the observations of how long it takes for bodies to adapt to the heat.
4/n@GraziosiSergio @Remittancegirl @noodlemaz I find this with hiking...it takes a while to get your 'legs' so to speak.
I think there is something about bodies taking time to transition and adapt as you say. Even rewire some neurons cos it sounds very much like what happens with learning a motor skill - you're better the next day after sleep cos the brain wires the process in?
It's why 'sleeping on it' is actually a good idea, as is breaks.

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.
@vriesk @Remittancegirl I live in the Southeast US and a couple weeks ago it hit 95f and 90% humidity. Lasted a day or two til a storm broke out. I'm a heat loving reptile and even I wouldn't go outside. No breeze no nothing just sticky goopy air
We regularly hit 80f with at least 60%+ humidity.
Obviously it's dangerous why do you think we're here talking about it -
@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
@vriesk sorry, my original post was ranty.
Weather reports often do not reflect reality. Monitoring stations are not necessarily where people are or under the same immediate conditions. They tend to be placed for convenience, not for accuracy. Do not rely on them to determine what's happening to real people.

@noodlemaz @UkeleleEric @Remittancegirl
That's fair enough. If they do, they do. So does "room temperature drinks" work for you (it is my own default, TBH)?
(Asking because bodies are complicated and not all the same, so I genuinely don't know!)
@GraziosiSergio @noodlemaz @Remittancegirl cool or room temperature or hot.

Living in the American Southwest in the 90s, they began to put misting fans on restaurant patios. It made a 100*F (37.7C) day so much more bearable. Moisture and a fan could drop the ambient air temperature enough to make it comfortable.
They became available at reasonable prices for home use too. The simple systems are just an atomizing watering ring in front of a fan.

A year ago… I was looking at low tech cooling and besides smart building design (old school design), India had vetiver rolling shades for windows and doorways that you could either wet, or could buy a dripping device, that would help cool air as it came through, plus vetiver smells good. I wish someone would import those here. Loved the idea. -
@Remittancegirl heat and hot food correlate? I though it was just to keep it save
@Bene @Remittancegirl I once mentioned to a Mexican restaurant owner in Tallahassee how much I loved spicy food. He ducked behind the counter and offered me a squeeze bottle of his mother’s special recipe. Hottest thing I ever ate. Sweat pouring off my head. But when I went outdoors into 38 C and 90% RH, I couldn’t feel it at all.

@Remittancegirl 43°c today's temperature in India...
... Drink lots of lots of water to avoid dehydration. Try to eat watermelon 
if available to balance ur water lvl. Cucumber 
also a good source of water... Onion is the best heat resistant and keep u safe from heatwave... Rest is in god hand

Some do, but a lot are designed to be lightweight and let through a lot of sunlight. A year or so ago, I was given a modern parasol, which has a thick UV-proof layer and is white on top to reflect as much sun away as possible. It is much cooler when you go under it.

@fietsria thank you! It's been awhile since looking.

@david_chisnall ultimately any shade is better than none but I’m glad you have an extra good one!

What I find even scarier is that most governments and most of the financial world still will not truly acknowledge climate change enough to stop burning fossil fuel. Even when it would be absolutely feasible to do it.
That IS scarier.

Some of the old buildings in HCMC with clay tile roofs have a drip system that leaks little streams of water onto the hip of the roof. The evaporation works to pull the denser, cooler air in through the windows and doors on the bottom floor and convection pulls it up into the second floor. I don't know if it works, but it was very popular with the French. @MyWoolyMastadon @gbargoud @fietsria @vriesk @svenscholz

@mamapanda Please, let us not be mean to each other. @vriesk means well and his post wasn't malicious.
Please let it be.

@Remittancegirl with 38° at 90 % you'd be way above wetbulb temps that are life threatening. Sweating as a cooling effect doesn't work any longer, when the air is already full of moisture.
If you still have cold water, you can cool down your body and the surrounding temps. Do NOT stay longer in such an environment as absolutely neccessary.
Get into cooler surrounding. -

@radioclash The very best advice I got when I first moved to HCMC was to learn to sleep without aircon. With just a fan. Because it really helps the body to acclimatise faster. Luckily, I didn't have aircon, so I had no choice. But I must admit, my body adjusted pretty quickly.
But I think for what people are going through in Europe right now, it's a serious shock, and it is not like the change is permanent.
