Quite some time back after that girl died out near lake Eyre, my memories of the Page family, and a few other deaths. I decided to find out what actually happens to the body during heat stress.

Came across an excellent Paper describing the breakdown of the human system under these circumstances. Unfortunately I've lost it after a few computer problems.

Did a lot off searching on the web, the usual stuff comes up, but nothing describing the physiological effects of hyperthermia in such detail.

In non medical terms he describes the progressive break down of the body. One of the things that impressed me about this fella was his ability to describe it in simple terms.

Most of us know the basics such as adequate water, getting into shade etc. But this fella was more on about understanding your body when things have gone downhill in the bush.

The author may have been an Aussie Doctor or University type. Has anyone come across this work? Sorry have'nt got anymore detail than that.

PS Thought I knew a bit, but this fella tells you what's happening to the body. Might make the difference one day for those who get off the track. Good read.

Regards

Kim

I know what its like to suffer from Dehydration, totally different
situation, than being stranded in the Outback, I was working on a
Roof on the Gold Coast, this place was the size of four Football
Fields, we had to help Install a very large Airconditioning Plant, my job
was to prepair the Roof for the Frame Work and replace the Roof
Sheeting and new Flashing, we started at 5-30am in the middle of
Summer, I thought I would be ok with Two 2-litre Bottles of Water,
it was hot as buggery,the other Contractors and Cranes ect came
from Brisbane, so as soon as they had finished there part of the
job, they left for home, in the early part of the day I drank most of
the water I had with me, the sweat was just pouring out of me,
there was no shade, it was like being on a large sheet of Al Foil,
now I had drank 4 litres of water and did'nt even feel the urge to
Urinate, the sweating had stopped, I was going flat out trying to
get the roof finished, before a predicted storm, I finished the job
around 4-30pm, as I was taking my Tools & Gear off the roof, my
legs went from under me,had the worst Head Ache you could ever
have, and I started Dry Reaching, I phoned my wife, because I
could'nt drive the Work Truck, I was put on Drip, and did'nt
get out of Hospital for Two Days, I would hate to get into that
situation being stranded in the Bush or Desert.

Cheers

Sounds like the bloke may be Dr Paul Luckin, an Anaesthetist and Lieutenant Commander in the Royal Australian Naval Reserve who is used extensively by Search and Rescue organisations in Australia to determine such things as "Time Frame for Survival".

I went to one of his private lectures and the progression of the human body when exposed to the environment was explained in detail, yet simple to understand. It was a Powerpoint presentation however, so i don't have any notes, though it would be good to see a document describing the progression.

Apart from the black tongue, protruding eyeballs, lack of energy to even stand up etc, you start to hallucinate. Much like a cyclist on the Kidson in October :))

Hi Kim,
I suspect Bob Cooper is the name you're looking for.

www.bobcoopersurvival.com

He pushes the idea that your early decision making dictates your actions for survival. If you minimise water consumption from the start, then you starve the brain and you enter the poor decision making period earlier than if you had consumed more water early in the survival period. Contradicts commonsense, but your early decision making dictates your chances of survival as things get worse.

Cheers
Chris
