How does a hot body produce cold sweat?
When our bodies are over heated they produce sweat to cool off. Since the sweat comes from inside our bodies, how can it be cold?
Theory: I'm not sure if I am right, but I think it is because of heat exchange. The heat from our bodies goes into the sweat that gets cooler when hitting the cooler air.
I might be wrong though.
Well you could ask a clam but they might clam-up on you, get it?
Your body is over compensating and trying to cool you down by producing what it needs to get the job done.
The sweat is not cold as it comes out of our body. It is body temperature, and is only cooled through evaporative cooling. I just looked up the numbers to be sure, and for each kilogram of water vaporized 2,257kJ of energy is used. Thus, your skin feels cold.
Evaporative cooling works great and is also used to cool houses.It was very popular where I lived in the Sahara (people sprinkled water on the ground in the patio) and in some parts of the US it is called a swamp cooler.
I always think of sweat as cooler than hot skin because it's purpose is too lower body temperature.
because the cool air hits it or our bodies are so hot that any water on us would feel cool!
Evaporation is the likely key, but a "hot" gall bladder attack can sure bring it on!
its actually not that cold your body is heated up so much that the sweat it produces feels cooler.
Sweating is a protective mechanism to protect the body from the ill effects when it is overheated. Sweat takes up the latent heat of the body and is evoporated due to heat. The heat of the body is comsumed in process of evaporation of the sweat. Thus the body starts cooling down as its heat is used up. The sweat also takes up the temperature of the body, which is gradually cooling down and it appears that sweat is cold in comparison to the surroundings.
When you feel hot you sweat to feel cooler so the sweat is cold when out of oyur body
The sweat is cold because it interacts with the outside temperature.

Would you prefere to sweat in 100 degree weather or freeze in 12 degree weather?

I am sooo loving not being in 100 degree or more heat. It feels so good to be finally cooling off a bit. I think this has been the hottest dryest summer in years. How has it been i your neck of the woods?I look forward to the leaves changing and fall/sweater weather.

I hate, I really do. Every Christmas holidays I am down with something. This year I thought I missed it. No such luck. I am down again with cold. Any suggestions? Is it a curse? Why on Christmas?
