Why Does Humidity Make It Feel Hotter?

In my area at 10pm it is 83° with a dew point of 76°

Having lived 19 years in arizona you never get to cool off the sweat evaporates to quickly to really add any extra cooling vs anytime I was in the south the humidity allowed the sweat to stay and cool me off longer then back home in arizona

Me: "It's so damn hot!"
Some guy from southern US: "But it's only 30 degrees celsius, how is that too hot?"
Me: "30°C and 85% humidity. It's like living in the Amazon rain forest... In the middle of a pine forest."

I work outside in GA I can’t really avoid it. But it’s usually not too bad but when I’ve come home showered and then walk back outside I can literally feel a wall of humidity and want back in my AC 😂

dew poit?

Wet bulb temperatures ?

Thanks , God the humidity in my country it low 😎😎

I'm watching this when the humidity here is 100%

What’s Celsius

It is currently 98% humidity outside with a temperature of 27C. This is criminal to have to work in

People who live in Southeast Asia: 😎😎😎

Im sitting in my fridge while watching this

Watching this as it’s 100% humidity and the dew point is 73°

humidity....

Good man

I Really hate this type weather climate 🤔😕😠...

dewpoint happens if ther is 100 percent relative humidity,,how can u hav dewpoint in ur lecture?

my county is humid

So in other words Texans should never go outside lol

I don't understand why all these new videos use Celsius instead of Fahrenheit. It's like all of a sudden people started using Celsius and kilometers instead of Fahrenheit and miles. That's why i stopped watching these videos.

Thank you so much, now I can sleep in peace

Humidity sucks

Can confirm humidity makes a MASSIVE difference. Summers in the midwest were absolutely unbearable even when it was 70 (which was rare, it was usually 90 - 105). 75F in humid Missouri genuinely felt like 90F in dry-summer Montana. Case in point, it's actually a little humid today here in Montana (60% humidity), and the 80F feels around 85F instead. But a few days ago it was 90F with only 15-20% humidity and that actually felt like 80, maybe even 1-2 degrees cooler.

I'm old enough to remember Farenheit in England but, for the past 30+ years, we've used Celsius, and I've become more familiar with that. It's great to see a simple explanation about humidity, plus explained in the 'international' standard of Celsius.

Can a human train himself to get used to high humidity. I currently change my location. High temp is not a problem i get used to it but high humidity is killing me

hly shite. i moved from california to the midwest and my misery index is booming

Celsius? Cmon.

Absolutely hate humidity.

FINALLY!!!! Someone explained how useless "relative humidity" is!

Dew points over 65° are sticky

Error in the Video;the body temperature is actually 37.5 Degrees Celsius not 37

You just make things complicated explaining too much.

I lived in singapore. When i went to a even warmer country but with much lower humidity, it was like a chill weather for me

my house suffers from rain leaks and it increases my upstairs humidity to an average of 80%, for me its way too cold now and it doesnt make me sweat

We have a dew point of 27 in my city during june july and August. Kill me plz.

😢 the dewpoint is 23° now 😢

I haaaate humidity, the months of June to mid October are absolute hell for me 😭😭😭

Thank God I have central AC in my home but the electricity bill isn't very pretty either.

It's April 30th, 2024 at 6.15 AM and the temperature in Bangkok, Thailand is 30c but it feels like 36c or even more as the humidity is 86% & the dew point is 27c. 🔥

I went to Europe and came back understand and preferring the metric system

Would a dehumidifier help?

I live in a sub-tropical climate state, Mississippi. The humidity is very high.

that shirt is - something else. ha. i can't look at for long its too much. sorry will have to move on

Dew point is 76% right now just out side NYC at 1am!!!! 74 degrees out but is sweltering and we’re going into a 90 degree day and the humidity is 91% right now after the 4th of July in 2024! The summers are getting hotter and wetter! One year the grass died and last year it was hot and a lot of peoples basements flooded because of the heavy rains that saturated the ground and this year, summer basically started in spring and it’s only getting more and more humid. In the 1990s, 90 degree days north of nyc were rare so when they did happen, it was a big deal. Now we’re gettin 90 degree days for a week with brakes of 82 plus. It’s just freaking hot! It’s reminding me of south beach in the summer in the 90s. I can’t imagine decades later with the heat rising this much this far north what Miami is like. Vegas I’m Aug I felt for the fist time before vivid hit and it was 110 but dry heat. You barely sweat. It’s so different but more tolerable surprisingly than 90 degrees after a thunderstorm! What is happening to the weather this year! We’re not even in august yet and we have had a months worth of 90 degree days.

Dewpoint is by far the best indicator of what it feels like outside. To me, the numbers of temperature and the numbers of humidity are just that, numbers. The numbers give you a hint, but they do not put "what it feels like outside" into understandable terms.
Even after you know the dewpoint, you are not finished yet. You do not have enough information.
You need to, once you have your dewpoint number, look at a dewpoint comfort chart.
The comfort chart gives various ranges of dewpoint numbers, and assigns levels of comfort to them.
Here is the chart :
<55 Pleasant
56-60 Comfortable
61-65 Getting sticky
66-70 Uncomfortable
71-75 Opressive
76+ Miserable
There are dewpoint calculators online that you can use to get your dewpoint number. There are also dewpoint charts. Once you know the dewpoint number, you can compare it to the chart and really know what to expect when you walk out the door, that is, if the chart reads favorably enough to even want to open the door! If it's "oppressive" or "miserable", I just stay in the house!
And by the way, the "heat index" number that the weatherman gives is also useless. Go by the dewpoint and the dewpoint chart and you will always know what to expect.

i am watching your video with 44°C along with 80% Humidity and no air conditioner ...

Now that I'm not far from 60, I see why older adults and seniors risk greater death levels in high humidity/heat. It's awful at any age but I see how we could die from it as one ages. I love the winter. Summer= nasty

Why would the sweat on your skin care about the absolute amount of moisture in the air? Wouldn't it's ability to evaporate depend on the relative humidity measure? I've been struggling to see how air at 50F dry bulb and 50F wet bulb (100% relative humidity / dew point ~50F) - which is considered dry as a dew point measurement - could hold any more moisture. I assume there must be something more complicated going on at these humidity levels close to saturation. I've heard that it's difficult to get a measurement of air that is actually 100% RH. Is there a process that practically ensures the dry bulb is a little bit higher than the wet bulb? Does the human body warm the air right at the skin enough to allow the evaporation of sweat at cool and saturated conditions? And it can do this up to about 95F when it reaches the limit that the body can warm the air right above the skin?

If the convective heating of the air from the body is what allows evaporative cooling at these low temperatures, other topics like mold growth / drying clothes outdoors would not get the same 'benefit' and so in those matters, the air would not be considered dry?

Japan is a Supernova right now. It’s getting hot year by year.

I prefer the dry heat. Everyone talks about how hot it is but 30 degrees dry compared to 30 degrees with humidity is totally different.
