How Does Sweat Work?

Learn how the human body regulates its temperature through the use of sweating. Find out more about energy transfer from your skin to evaporated water molecules and other examples of "sweating" in nature.

It's the change of state from liquid water inside of you to water vapor outside of you that accounts for the drop in skin temperature. This entire process is one of removing LATENT (or stored) HEAT which, to this day, is the principle of modern air conditioning. The water in your sweat is a natural REFRIGERANT but it is not nearly as efficient as other (mostly artificial) substances which do the same thing inside your AC system.

In response to Matthew Dockray

Temperature, which can also be considered as heat, is a form of energy. It is not the only form of energy, but it is a form. Now when you add energy to any object, you're not necessarily making it hotter. The energy could be kinetic, elastic etc etc.

Hope it helped :)

Watching this made me feel like I'm in class wtf

If only you'd uploaded this a week earlier... I had a six marker in my biology GCSE on this last Monday!!!

Ok dude, Never meant to come over here, I just had a question and thought your video looked like a good one to click on.
I never would have thought, but one word of your voice is more than enough to give you away.
The legendary Superjombombo has got something to teach us other than how to spam twice the value of a factory, but with republics instead.
At any rate I am sorely disappointed to see you spread such misinformation. You should know that sweat is unique to primates.
Honestly I'm offended as this is the super power that allowed humans to dominate the earth.
tisk tisk.

You should make a video about the grand canyon! Like the biodiversity or geology

In a swamp cooler, warm/hot air is passed over water and heat from the air is transferred to the water, some of which evaporates. The transfer of energy from the air cools the air down. So is there also this effect going on around a sweating skin? Is heat from the air helping to evaporate the sweat, thereby cooling the air, and then maybe this layer of cooler air around skin also helps to cool the body? Or maybe it's detrimental, in that the evaporation due to warm air is just wasted sweat, instead of drawing the heat from the body, the sweat drew it from the air, so body doesn't cool?

this is why if your feeling hot you shouldn't just wipe off your sweat

No tadpole video?

Also, good job,

Isn't temperature energy?
Because I thought the more energy you add, the hotter things get

I may be wrong (I am only in year 8)

Im sweating so hard how can i remove or stop the sweat to my body

From your Tetanus video, just a question, there is dirt in the air. (as you said) So if you breath in outside, wouldn't that get dirt into your lungs, which can be coughed up, then swallowed, then into your blood stream...

Hey chris!
I was just wondering, do you know where hyper sweating from hands come from, and how could you explain it? I literally sweat more from hands than anywhere else, so much so that I can never have my hands dry, as sweat is constantly replenished.

It's sad to see what Caillou has become after his show got canceled

Does sweat contain urea, meaning it is not clean?

[karenwilliams]

i would like to speak to the manager of sweat

[aaryanqureshi]

Me as a hyperhidrosis victim watching this and wish I am ready to be hot as fire but please sweat don't come out from my hand and feet 😭😭 plz
