The temperature and human?

Question

How can we tell what is hot, cold or just ok?
Does anyone have an experiment of the normal temperature that people can stand? Is it 37c?
Since i was little, ive always wondered if human can stand the low temperature better than the high temperature, that i always refused my mom when she wants me to get something out of Microwave..(or if i didnt refuse, i would take a lot of things to cover my hands)

So, tell me what you think..or if you're putting left hand in microwave and right hand in the fridge, tell me whats the result.

(Sorry for my complicated english and sorry for so many questions)

Well, yes i do agree with your idea of different toleration of human. Im sorry that i didnt make it clear. I was tryin to talk about the temperature of the things we touch, like touching hot pot at 100 c (for example) on the gas stove. That cant be possible. what if you touch a cold pot at -100, is it gonna be somethin different. So, the weather doesnt explain about this, does it.

(those temperature degrees are just the examples.)
Well,
I was kidding about the microwave.

thank you for the ideas. but, i cannot say that they are right or wrong. I need an experiment. im tryin to find a way. Have a nice day, everyone. ^_^

Answer 1

Human body temperature is, as you said around 37 °C.

As you increase the surrounding temperature you , at first feel warm, then hotter and hotter as the temperature rises.

I worked in the Sahara desert for 30 years and temperatures were often at 55 to 60 °C but, a very dry heat and was bearable for an hour or two.

When humidity is high, such a temperature would be unbearable.

Conversely, I now live in Calgary, Canada, where, in winter, it gets down to -40°C. Again, very dry but you must wear the appropriate clothing and not stay in the cold too long.

The temperature people can stand, depends on the person but, I would say that comfortable temperature would be around 20 to 22°C.

If you hold one hand in fairly hot water, and the other in cold water for a while, then quickly both hands into warm water, the hot hand will feel cold and the cold hand would feel hot.

It's relative

First of all, I do not know how you can operate or turn on your microwave when you are putting your hand inside. The door will not latch to activate the microwave. Sure, you can put your hand in the microwave but nothing really is happening. It is NOT like your putting your hand inside an electric or gas oven.

In any case, please tell us what model of microwave you are using that you can place your hand inside and still activate the "un-closed" door to operate the microwave. Or, how thin are your hands? Either that or you are just so full of it!

On the off chance that you can place your hand in the microwave, then you are just asking for trouble. It is stupid because you are basically cooking yourself! The microwaves will boil off the water in your cells, cook your tissues and eventually char your hand.

Placing your hand inside the refrigerator is another story. You can do it. That is easy.

Now for the question of which one, hot and cold will a person tolerate more is basically a function of the person's genetic makeup. Some people like those who live in igloos, will tolerate much lower temperatures than people who live in hot, torrid climates or deserts. But if habitability is concerned, not a lot of people can survive the hot, parching desert than the ice cold arctics.

Humans need water so survive. The likelyhood of surviving in colder environments is a greater than in deserts. However, without the benefit of fire, people can freeze to death much faster.

Answer 3

More damage the temperature do to your body the more painful it is. But I heard people meditating or doing something like that can with stand pretty extreme temperature range.

Answer 4

Not sure what your point is.

The human skin will get burns when exposed to surfaces in excess of about 49ºC. Likewise, you'd experience frostbite at temperatures below 5ºC.

If your skin temperature is about 26ºC, then the two damage thresholds are roughly symmetrically placed around the skin temperature.
