so humid, you start growing fungi, mold and mushrooms on you
That's how the zombie apocalypse starts.
mushrooms grow in my armpit
infinite food supply 😶@@FloridaMan69.
That's how eczema starts...
I actually have fungi on my skin in multiple places
the amount of damages must be insane!!!
People don't really cares much about water damage like this in Guangdong much, at least to my experience. The wall will get wet every year and it is a natural occurrence. But it sure make life a bit difficult when it is raining inside or some wall paint falling on you, making everything covers in white dust.
Most of the damages at home can be avoided by shutting all doors and windows to the outside world all day.
Correct, and despite all of it being preventable by creating quality housing, China has a "never fix it" mentality so they just keep tearing stuff down and replacing it with new tofu buildings.
@@Valkyrie_Yukikazein the video it said it's the worst it's been in 2 decades. so it isn't a "normal occurence" as you say.
@@st20332 Yeah, this year is pretty bad but what I mean is that there are going to be moist/water damage on wall and molds every year. So people are used to those kinds of things so it isn't really like a "huge damage". That's the point. Things will get wet and moldy, even when things aren't as bad as this year's.
So humid that you can just take a deep breath when you're thirsty.
Your lungs aren't supposed to have water in them lol
@@YFZriderdude15breath with mouth!

@@hdldm7970 still it will go to lungs lol 😂
@@YFZriderdude15your lungs breathe out water. They're kind of used to it. as long as you don't get too much in it.
As someone from SETX, the best part is when you're trying to drive at night in 100% humidity, and the windshield fogs up so bad, you literally cant see your own hood. You have to put AC on full blast + recirculate to dry out the interior, and if its cold outside, you suffer. Same with houses too.
Yeah. I’m from Northeast Texas and the humidity here hovers from 70-90% normally. It’s 97% humidity right now, but thankfully it’s somewhat cool outside. I know for a fact I’ve seen it that high during the summer though lol, it was terrible.
I hate the weather here in Houston..
@@barebones2001it was pouring in Houston and flooded just now.
I hate when we enter the spring. The constant mowing because the grass is ALWAYS dewy if not sprinkled on and the +90% humidity multiplied by mosquitos and I just talked myself into paying for lawn care this year.
You know you can get the same effect, running the AC plus recirculate, with the temperature set for warm air? No need to make yourself suffer blowing cold air.
Okay, the red paint coming off the LNY decors were seriously creepy.
No it’s hilarious
No it's creepy

Nah how can you breath it’s like a greenhouse
as a florida native, I felt the same way when i went to live in the desert for a short time. It felt like the air was so thin because there was almost zero humidity, i wondered how people could breathe normally.
@@Speedj2Maybe because I grew up in the desert West Coast, but I'd prefer the dry air to whatever this video was.
They already breathe smog.
From sc when i moved to the desert i absolutely could not sleep or breathe right without a humidifier @Speedj2
@@MrBlack-vd2ws The pollution in Southern China is not as bad as it is in some of the Northern cities. Most Southern cities have pretty clean air. You can look at a pollution map of China and see that this is the case. These cities usually have AQI of around 20-50 year round and can be lower than some of the suburbs in the US. Its not like these places are rural farmlands either. Yes it is pretty bad in Northern China, but don't just generalize such a big country.

30 °C at 100% humidity is a wet-bulb temperature. Anyone who is out of AC or stuck outside for more than a few hours will die... and it's only March.
Even using fan or water mist is basically suicide at that condition
Have you seen The Dimming documentary?
where i live, 30+ °C at 80% humidity is a daily things. you won't die.
What do you do to even prevent injury in something like this? seems like only thing you can/should do is just lay down and be as still as possible to not generate sweat, and find a way to remove moisture as much as you can.
Get in the refrigerator.
I've lived in Brazil my whole life and I've never seen anything like this, not even in the city of Manaus, in the heart of the Amazon, a humidity level of 100% was recorded.
It happens when it is cold at 10c and the next day is 30c
Relative humidity is a different measurement than simple humidity. It takes dew point into account
Rainforest prevents this from happening perhaps, @@ReineDeLaSeine14. China is almost zero trees, but BR is full of it everywhere
@@matheusb.r.461 There are trees in cities and forests around them in China, mostly in the southeast and the northeast. The north and west have deserts, yet their government has different plans or they had already made them to reforest or turn deserts into forests. People is also motivated or even paid to plant trees. There are other projects already made or planned for building what's called Vertical Forests, building apartments with trees on the sides of every floor.

Where I live, we have stretches in the summer of 40+ days of between 38°C and 46°C at 54% to 60% humidity. But I’ve never seen water dripping off the ceiling 😬.
I live in Shenzhen and I easily avoided this humidity vapor issue by simply shutting all the windows and turn on the AC to dehydrate the house and kept everything dry. It’s pretty much common knowledge for locals.
About to say, these houses would also be built with climate in mind right?
Cost is a major I assume. Running the AC like would be expensive.
@@dantruong2582it's not the AC, it's the expensive insulation that prevents humidity from getting in in the first place

Living in a tropical country, humidity is always there and it just make things hotter like a natural sauna.
Though the bright side is that your skin isn't going to dry that easily but still drink water because you will be sweating.
Not, it's not like a natural sauna. A sauna generates dry heat. I'd say it's more like a steam room.
@@paulparomasauna can do both dry and wet heat
Read Wikipedia
@@TheRanguna I don't need to read Wikipedia. I have my own sauna. Dry heat is what true sauna is all about. The humidity rarely reaches 50%. Turkish bath is wet, on the other hand.
Yeah, but as Indonesian, I never experienced this kind of extreme humidity.
It keeps you(r skin) younger...😊
I've experienced 100% air humidity in the Netherlands, during an extremely hot spring (something that is becoming increasingly prevalent), and it felt *awful* because no amount of sweating helped with temperature regulation, and water from the cold tap came out *lukewarm* but we were fortunate that our houses were insulated enough to not get water condensing on the ceilings! Unfortunately... Dutch homes, or even most European homes beyond the Mediterranean tend to not have any AC installed by default. The Netherlands used to have much colder winters, so our insulation philosophy is to keep warmth IN.
I guess that there is much to come for European people. We could face also more of those crazy weather events.
i mean in denmark, relative humidity is masically always at like 75% and regularly at 85-95%
Common for a country surrounded by water.
Relative humidity is relative. At lower temperatures the air cannot hold as much vapor as higher temperatures. Denmark is a colder country. 95% humidity in Denmark is nothing compared to 95% humidity in a hot climate.
Same in ireland. Its always between 80 to 100
Yep. It's not the complete picture. Fog outside also means it's 100% relative humidity. But normally, this occurs when it is colder outside than inside. Air can hold more moisture when it's warm, so during the day, the air heats up and absorbs more moisture. During the night, the air cools down and 100% humidity is reached. However, when you take in that 100% humid air from outside and heat it up the humidity drops again. So this isn't a problem when outside it is colder than inside.
When the inside temperature is colder than outside, and outside 100% humidity is reached, that's when you get this kind of insanity. The moisture in the air will condense at any surface it touches inside. So they must've had hot, humid air move in quickly from elsewhere, while the buildings were still cold.
The problem is the 100% relative humidity at 30C+. As the guy above said, 100% humidity otherwise just means fog outside.
I was not well informed to have a dehumidifier many years back, and our walls would get damp and grow mould. Now we have one in the living room and one in each bedroom. It sure makes a big difference. And it sure helps with the AC as well.
do you mean you were well-informed and not?
They said not, so....? What is your question again? @@kismetau
@@lsrain if they weren't well-informed why did they then say it made a big difference to them? I'm confused.
@@kismetauthey said they weren't well informed, and they had mould. (In the past)
_NOW_ , they have de humidifiers . They learnt from that experience and are more informed now.
@@kismetau English isn't their native language, so I took it to mean they didn't know about dehumidifiers and how they could help. They now know about them and are using them to reduce the humidity indoor. While I could be wrong that is my interpretation of what they said.
One thing to note is that water from a dehumidify is clean and can be used for drinking.
What horror is this? How can someone without AC survive 100% humidity weather.
People from Third World Countries:
First time?
Never imagined it. Even me as a 3rd worlder, humidity stays at 60% to 70% at most.
Stuffs that placed on your concrete floors starts to get moist and that's it. At night, concrete houses starts to cool-off. Not to mention, we only have electric fans and ceiling fans to tide through the intense heat.

@@supremebuffalo6322 enlighten me please. It looks like extreme condensation. Which humidity does play a part in
@@supremebuffalo6322 With the right construction methods you can regulate interior humidity different from outside, even passively... Moisture barriers etc... If this is a seasonal thing here, houses should've been built for it...
Also the fact that the humidity condensates like this, is also an indication something more is going on besides the 100% humidity...
As someone in eastern Canada, yes, we go through 100% humidity every summer.

The world is not ready for 101% humidity 😳
you mean 100% right? there can’t be more than 100% humidity, 100% humidity means the air cannot hold any more vapor. it is the saturation point and is a hard line. :) there is absolute humidity, which can go past 100%, but it is used in baking and is not relevant..
That's a joke
this kind of condensation only happens in tofu dreg buildings, with proper insulation this wont happen

@@coyotemars5130 so basically he is right😂
We get this kind of humidity in the southeast of the US all the time. We have air conditioners so it's not humid inside and water doesn't condense on every ceiling and wall. This is humidity + no AC and leaving the windows open.

Idk for other east/southeast Asian households, but we always use the dehumidifier during spring just to combat this kind of weather. It’s especially nice if you have a small apartment since a small dehumidifier is sufficient (I live in Hong Kong so most of us live in small apartments)
I don't know about other SEA countries, but here in *most* part of my country Indonesia (part of SEA nations), i said most because our country is too big to say everything the same
We don't have that thing, "dehumidifier" thingy, we just live like usual, probably because of our country is under the Equator Line
We don't have other season except Dry and Wet (like Rain), since its a Tropical country, so we don't have winter, spring, summer, autumn etc seasons in here
But some part of our country has a cold temperature, but it doesn't have any bad news like people died of cold, unless you got caught up on Hypothermia especially on a mountain but that's very rare
About the Humid, in here its more like dry than humid, sometimes only foggy, but its because of pollution back then is really bad, but now? Not so much, because we tried to reduce the amount of pollution
So i don't know about other SEA countries, wether they have the same problem as yours or the same things goes just like ours 👍
Im certain they are doing this too there.
But its way more then their dehumidifying systems can handle.
Dont underestimate how freaking much water air can store.

What people have to understand is humidity is relative. I also live in a place where the relative humidity is high, but the temperature is low. 100% humidity at 30C is lot more water in the air than 100% humidity at 5C. 100% humidity at 5C is actually super dry.
What is happening here is the inside the house is slightly cooler than outside. Someone opens the windows or balcony doors, hot humid air rushes in. The slight drop in temperature squeezes all the water out. Hot air can hold more moisture than cold air.
This is a great answer, people forget that it's RELATIVE humidity. and that yes hot air can hold a lot more water in it than cold. So 100% humidity (air can't hold any more water) at high temps, that's a lot more water being released on everything and tiny temperature changes can make for big bad results. Close all the windows and buy a dehumidifier.
Yes it's like Vancouver which gets tons of rain from fall all the way through winter, but our humidity is super low. And in the summer it gets quite hot but it's super dry, so humidity is also low. It's just a low humidity place all around. In fact if you like rain and not overly hot summers the weather is just about perfect
@@d-rockanomaly9243 No, you are also missing the point...

I’m confused, there are other places in the world with 100% relative humidity as well but without the insane amount of water everywhere. Is there a reason for that in particular?
Im not sure but its probably because of rapid changing temperature, from cold and sudden warming may cause this. Where i live, 100% humidity can occur but because its always warm,so it never becomes like this. I guess this is why it occurs more in places where its like the tropics but still get quite cold weather like northern vietnam/ south China.
Yeah, it has to be temperature changes. The air temperature rises, but the buildings take time to warm from the sun. So when saturated air comes into contact with cold walls and ceilings, it condenses.
@@lysandersensale2792 hahah yes this must be it, after typing this comment i took a while to recall what i learnt in science lessons back in school 😭
It only rains when humidity hits 100%. Same with fog and mist and snow. The captioning on the video makes no sense.
It is also relative humidity, not absolute. Warm air can hold more water than cold air. So 100% humidity at 35C will have a lot more water in the air than 100% humidity at 5C so there will naturally be more condensation forming.
Here in America in south Mississippi every summer is 90 degrees with 100 percent humidity for months at a time.
Yep. Went to Guangzhou as a transitional airport on my international flight. When we landed, it was PITCH BLACK at dawn 5am. And the pilot announced it was 80°F. Later, they had a little garden and i went outside. It was only 9 am or so, and it was cloudy - i still hadnt even seen the sun yet, and it had to be 88. Better yet, the humidity was so high it was like being in a cloud.
This wasnt even their hottest days, because we hadnt seen full sun. Being nearer to the coast makes it worse!
Major sweating without moving. I’ve been in south Korea doing an installation and felt the wrath of their humidity. But I was mostly in a temp controlled clean room. I also experienced their rain storms where each drop was like a cup of water
It's kinda weird to be honest,I live in a country where it's almost 32c 80% humidity where the air feels incredibly warm and sticky and suffocating even when u just took a bathe 5 mins ago but I have never witnessed condensation form on the surface like that in my life....unless it's cold and if it's cold inside like air conditioned place it wouldn't form like that either.....condensation forms on the outside, the only situation that droplets can form like that is if there is no air flow, and ur taking a hot steamy shower or it's a gd sauna or something.....
But the whole thing boggles my mind.....first of all wood or concrete surfaces don't sweat or form condensation like that,and if it's that warm and humid out there,stay in ur concrete apartment room and shut the windows and make sure ur windows are dark and tinted or draw the curtains from morning till night,it will keep the hot humid air out and trust me ur room will be much more comfortably cooler and dark than outside.
At night wait till it's like 11pm or 12 midnight when it's finally somewhat "cooler" then open the windows.....at 8pm the air still feels like a sauna outside.....
Or just get a air con or air dehumidifier,I dunno what these folks are doing.
The only reason it forms droplets like that my guess is these guys are in some wacky place In the desert in china or something,where at night the temperature falls by 10c at night and is extremely cold and it "rains" indoors. Otherwise keep the windows shut all day and stay indoors u will be fine.
At 100% humidity the slightest temperature difference (the inside being cooler than the outside) will lead to condensation forming, due to the inability of the air to hold water.
I think you hit the nail on the head with "no airflow". many of china's cities are overcrowded and poorly constructed and they probably lack the building codes to ensure that the buildings are properly ventilated.

You cannot have relative humidity beyond 100%, it's called dew point where the water must then condensate into dew. Probably the absolute humidity in your case was never very high to begin with. In the Chinese case the wind coming in from the seas at higher temperature (that can carry more humidity) settles into a place with the temperature drops significantly (like from 30 to 10), condensating the water molecules very quickly.
agree to disagree...@@user-ty3hp7wq6z
@@user-ty3hp7wq6z He didn't say above 100%. And as someone who lived in Alabama, yes it very often hits 90% and above in the Summer, and hits 100% multiple times a year. Swamplands are humid.
Seriously that’s a huge building flaw they didn’t take into account. I lived in a tropical area that has high humidity and the homes were built for it. These homes obviously do not account for their surroundings
It's China, they are probably just thankful the tofu dreg buildings aren't crumbling beneath their feet.
China isnt exactly a tropical region, is it?
@@MinkSquared south China is
That must be horrible
that's why dry mode exists with air conditioning
not all people have ACs
Da heck? 95% humidity is like a daily normal in my country but no where i have seen water droplets just appearing on walls like that. Is 5% that big a difference lol
warm & humid indoor coupled with cold outdoor. temperature difference
@@roku_nine how does the indoor humidity look like a burst pipe ha djust happend while the outside is cold? Im unable to grasp the logic. Even if its true…wouldn’t opening the window fix or atleast negate the level of humidity?
@@mobgaming1271 try leaving your refrigerator door open just a little and see what happen tomorrow. opening the window should help .i guess people in the video didn't open them. 🤷
air holds much more water vapor at higher temperature
There are different between 90% and 100% humidity, condensation will occur no matter what.
Why did they make a city in a place with so high humidity?
The pack of soggy lays chips brought back memories of when I was in school standing in the rain waiting for the bus 😩
Humidity is magnet for mold indoors. Both on food but also furniture and walls/celling.
Dehumidifer is needed 24/7 in this situation in all rooms.
That is scary humid
amogus
You back
100% humidity is actually quite common.
That volt stick was actually working correctly.
It must be a nightmare
I’m confused because tropical countries like mine (I live in Malaysia), humidity normally reaches 80-90%. Is this not common in countries with 4 seasons?
Usually in countries with 4 seasons only hot and dry
we get 100% humidity in Germany but its at 2C so basically not an issue in door
no, they are weak against humidity. the japanese claims that no other country can compare to their humidity in the summer. truth is it's only 70-80%. sure higher than most temperate country but a childs play for tropical country.
@@roku_ninethat is much better than in where I live. It's usually 30° with 85% humidity all the time ( at least this afternoon)
I live in SG but the kind of humidity in Southern China (I'm from HK) is not the same. It's humid in SG but the humidity doesn't stay the same all day, and as soon as the sun is out, it quickly dries up the rain and puddles (which has been an everyday thing currently 🤮), but still, it dries up pretty quickly. It's not the same kind of humidity in Hong Kong, when it's humid during spring time in HK, the moisture stays and lingers, for days, when that happens, your walls cry and weep all day long, for days.
Wow that's something never seen before
It's #Usual For Them
短时间内同时受到冷空气和热带海洋潮湿空气交互作用的地区才会有这种现象 建筑物温度太低 但空气却温暖潮湿 就像你在佛罗里达或马来西亚打开冰箱时所发生的凝结现象
it's a annual thing for them at guangdong😂cause of the sudden shift of temp from cold to hot in a short time period. basically what happens when you took out a can of coke from fridge, and u'll see it happen in front of you, but this at much larger scale
Why not use an air-conditioner? Or at least a dehumidifier? It would get the moisture out right away
That's basically every day all year here in Western Norway lol
Never see something like that before in my life.
It's called a dehumidifier.
for this kind of humidity, you need atleast a couple of dehumidifiers (which most families in Hong Kong have at home), and couple of ACs on at the same time, this is extreme humidity 😂
@@JL_hahaha0303 I am from North Carolina, US where it’s 32-37 all Summer with many days being 100% humidity (yes, daysss in a row) and we have central air conditioning through the whole house and it never gets wet inside. 😂 We also never use dehumidifiers. Also, to each person who keeps doubting me, come live where I live and you’ll see. 😌
@@jasminjanellI doubt that 100% you are claiming, if it truly was 100% humidity you wouldn't be able to see anything beyond 300 meters. And every car would need to have wind shield wipers activated whilst driving on a hot summer day to prevent condensation on their windshield. People would be covered in damp moisture to their underwear within hours. I'm guessing it's near the 90-95 mark.
@@average391 Hmmm so I guess I misread the temperature and humidity for 10 years straight? I guess the weatherman was also wrong and you are right. 😁👍
@@jasminjanell you could just confirm if you cannot see beyond 300m outside or if it was covered with a dense fog
Come to South FL in the summer. Like that 2-3 months out of the year.
So it’s basically raining inside
I think the problem is in large part due to no or very little insulation. 100% relative humidity is not that big a deal. Ask anyone in south Louisiana or in Oregon.
Do these buildings don’t have ventilation? This is really bad just think of the interior of the building there are probably going to be mold and it can be deadly.
I mean like everywhere around it is wet so no matter how much ventilation you have it will be very wet. But I do agree these are the extreme case they show here.
I think that's what's happening in many of these images. Adjacent rooms have air con on and it's cooling the walls / roof down below the dew point. It's causing the condensation.
unless you make your room as a vacuum environment...or else the air will be so wet that any ventilator will be meaningless...
Sealed Chips went soggy let that sink in
@@VasanthKumar-jk5jr It said unsealed
30 degrees and 100% humidity, man that must've been suffocating!
I can’t believe how much I complain about the humidity in Florida.
I just dont understand how ?!? like there must be no airflow or something, which create condensation
There is too much moisture in the air which condensate on almost every surface and it cannot evaporate with a humidity level of 100. Airflow is not gonna change that. It's also dangerous for people because sweat will not evaporate so it's very easy to overheat.
Must have terrible air ventilation and building design because 100% humidity doesn’t cause this
Umm, yes it does. Ever been in a greenhouse? Ventilation only exchanges inside with outside air. If the outside air is at 100% you can ventilate as much as you want and it does nothing.
Let me guess, you're American?
@@MurdogYT Lol, I live in Germany. I just understand what ventilation does.
@@zagreus5773 Central ventilation systems in large buildings where I live usually have both a heating and cooling system as well as a heat exchanger, but no dehumidifying capabilities. However I have worked on a system that did remove humidity as they needed the air to be about 2°C and that would normally be beneath the dew point. It used a lot of energy, but if used in these buildings together with proper isolation, it would still probably be beneficial both from an environmental and an economic poit of view. As these wether conditions is going to cause a lot of material damage.
@@Oddi92Sure, these houses could use a dehumidifier. Though as you said that costs money and if this is an issue only once per year for a few days, for most people this might be simply too expensive. It's China, many people are comparatively poor there and don't even have a simple A/C unit, despite the heat. But the commenter that thinks the issue is simply ventilation or "building design" does not know what they are talking about and seems to lack a basic science education.
@@zagreus5773 This is 100% caused by poor structure. A lot of houses and buildings, at least in U.S, have air/vapor barriers installed in the walls, ceilings exactly for this reason. Eastern part of Texas has hit 100% humidity before.
I’ve spent a week in an area of Mexico where the humidity was 95% and that was basically torture for someone like me. I can’t even imagine what it must be like in china right now
soooo, what happened to their PCs and other exposed electronics?
Question: is it dangerous for buildings? (Concrete, electrical setups, etc)
For Chinese buildings probably.. When you see the "toothpaste concrete" buildings (look it up). Yeah it's probably bad.
Eventually bad for organic materials like used in wood-framed construction, and will lead to slow water damage with mold, but doesn't really affect concrete/steel construction beyond promoting mold. That said, this is a result of improper construction, lack of air conditioning, and other flaws as this literally isn't even possible without design/constructions defects.
@@Demoralized88 Wouldn't air conditioning make it worse? It will create more cold surfaces that will cool down moist air, so that air will not be able to hold that much water.
I think the only way to avoid this is to completely isolate a room and dehumidify all incoming air.
@@user-kh6nn4vj8mProper working AC for a given envelope (indoor space, basically) makes condensation like this impossible. AC is a dehumidifier by design as much if not more than just cooling the air.
The AC Evap Coil inside a furnace or air handler in Central air greatly lower humidity by the water condensing on it, and falling into the drip pan where drains out of the house. By circulating the air throughout the house, it's able to dehumidify the whole building. Put simply, this isn't possible with properly installed AC, because it's intended to prevent scenarios exactly like this.
Your assumption would be correct if AC didn't also dehumidify and only lowered temps, but I and many people seem to not know that AC also dehumidifies by default unless broken. Additional indoor dehumidifiers work the exact same way to condense ambient water through a cold radiator and are only different in that they don't also cool.
Last thing, AC removes so much moisture that there's very little relative to humid air outdoors and, for anywhere near the same condensation on surfaces, they would need to be much colder. The kind of water in the air needed for a video like this would 100% need to be very warm and very high relative humidity, which makes me positive it's completely unconditioned and probably open to the outdoors. There's a huge difference in water capacity vs hot outdoor air and cooler indoor air at the same relative humidity (which makes it confusing) and will require far less colder surfaces to condense as you seem to know.
@@user-kh6nn4vj8m Air conditioning dehumidifies all air in the room.
0:50 this looks like a crime scene 💀
Lived in Shenzhen a few years back and my passport still has a flex from the moisture in the air
That is a problem caused by the faulty development... All you need is right air circulation in a house or apartment...
