Cool brains underwater

Thread Status: Hello , There was no answer in this thread for more than 60 days.
It can take a long time to get an up-to-date response or contact with relevant users.
hardly, but these cut asnd paste threads and the absence of logic in your defence of them can be considered so.
 


I wonder if you let the cooling reach the point where the temperature of the hypothalamus drops, it screws up thermoregulation.

Then it's harder to get your temperature back under control, and in particular warm the hypothalamus, which is deep within the brain, back up, so that thermoregulation works effectively again.

Anyone know if there are scientific papers out on this topic?

I know how thermoregulation can be screwed up. I had racing sailboat sinking under me once, long time ago, and since then I had elevated body temperature for almost a year after. It was like 37.1 all the time. My doctor said it was probably normal reaction to deep hypothermia event. I doubt I am getting to such deep hypotermia stages this time, like I said it is somewhat scary, sort of like a moonwalk, I know that I only have so much time and that all the heat I have is gradually vanishes as I keep staying in the water.

As water temperatures continue dropping this time of the year, I tried diving with shortie just so my head is cooled :head I know it is silly to think this will work, but anyways, I tried it. May get better with the time but for now I say, too much pain for so little gain. Freediving must be fun all the time :friday, I refuse accepting anything else :crutch
 
I like spam. Fried spam, spam sandwiches, spam with onions, spam-n-eggs, spam and beans, spam on crackers, spam and cheese. I like spam. I especially like spam inspired from down under.

Please refer to Monty Python for the definitive and most eloquent erudiation on spam. :t
 
For the record, there's another efect of extreme cold exposure.

Lynne Cox, the famous long distance swimmer, swam 1.4 km for 22 min at 0.5ºC in the Antarctic, wearing only a standard-issue bathing suit and rubber swim cap. The next day she swam 1.6 km for 25 minutes at 0.0ºC.

It was discovered later that she had sustained damage to the nerve endings in her skin, in particular the ones that sense pain. It took her quite some time to recover function, but it did come back.

The story is told in her book "Swimming to Antarctica", 2004, ISBN 0-15-603130-2

 
Her comments on the transparent ice shards hitting her face chilled me thoroughly.

I don't know how the seals/penguins avoid damage to their skin and eyes diving in that chunky icy stew.


 


Spam (the original Hormel Co. product) is from my home state of Minnesota.
Pseudo-spam can be found anywhere... :ko
 
Mr Wet, where does the word or name spam come from? Is it mixture of jam and sperm or Sperm Jam?
 
Oh for gods sake Poida, just come across him already!

That's not you hoonin' those Cats up and down the river?
 
Sorry I got off topic.

Can't get on topic on account of no brains.
 
No I was on a bus, dreaming about ham in a can
