Water so hot its cold

Irishstabber

Came in today with absolutely freezing hands. I tried running hands under warm water to make them usable again(couldnt move fingers).
But the water became hotter and hotter but after it got to a certain point the water just felt cold although the water was really roasting hot. I could feel the burn when I took my hands out from the water.

How is that? I dont understand it.

i know the feeling exactly! i think when its so hot your blood kinda runs away from the heat or something, though thats just me talking through my hat. someone clarify?

Sometimes the body cannot tell the difference between extreme hot and extreme cold.

When your hands are freezing, the best bet (imo) to warm them up is to run them under cold tap water.

Shouldn't really do that. Going from really cold to really hot bursts blood vessels I think. Anyway I remember doing that before and really hurting my hands. Best way is too just wrap a towel around them and let them get back to room temperature.

Heating up you hands and other parts can be dangerous... not life threatening... but problems!

yeah you can burst large amounts of blood vessells (as in really noticable marks on skin) by doing that...try to gradually warm them..don't do extremes

Have the same prob myself and so does the mother. Apparently it runs in our family, de mother went to a specialist and he advised it's a circulation problem that could only be sorted out with an operation on her heart and lungs. She didn't want to go ahead with it. My grandmother had it too. What i usually do is run them under cold water first to get them slightly warmer and them hold them over the radiator and they can gradually warm up. I hate that sore feeling if ya dip em straight into roasting water.

to the OP

your going to have some redness on your hand, and its going to become itchy.
My advise is get some sudocream on that to ease it.

I saw something like this in Braniac. The body doesnt know if the extreme is hot or cold. I presume it's something to do with that....

Sometimes my hands get so cold that the cold tap feels like warm water

Anyone ever drink a cold drink to get rid of brain freeze form icecream?

on a nerdy note check out the new issue of eother Scientific American or New Scientist (can't remember which one it is!). There's a theory that ice can now be created at non-freezing temperatures such as room temperature!.......not exaxctly the answer you were looking for but a related aside!

increasing the air pressure of a room should do that. i would have thought. Water boiled at the top of a mountain where the air pressure is lower has a lower boiling point.

Doesn't ice expand when frozen. I get what you mean by air presure increase. But surely it would want to stay as liquid as possible because that its most dense molecular form(or is it?). As you can probably guess, I have no scientific knowledge of this worth talking about though...

Respect to this ... made me laugh! still laughing ...

Its not that.....I don't actually know the science behind it cos i don't do science but it involves having a normal air pressure etc and passing electricity through the water....basically the idea is that you could have ice beside you (not melting) as you type on boards!

if you run hot and cold water from the tap at the same time it can feel like your hand is cold but you are burning...it's rather cool...

NoDayBut2Day

I've felt really hot water in the shower and then kinda shiver because it felt cold... kinda weird...

If you have cold hands then I can think of one (vigourous) activity for males that not only helps warm them up but compilmentarily feels as if someone else is performing said action.

So I've been told....
