There was an informative program on TV last week/Sunday? about the human body and how it functions and what happens to it in extreme conditions. (Heat, cold, wind chill factor, immersion etc)
The human body and especially the vital organs (brain, heart, kidneys etc) only works effectively at a certain internal temperature. During extreme heat/humidity situations, the internal organs gets cooled by means of blood that gets cooled by the outside temperature of the skin. Hence sweating. Dehydration means not enough more fluids in the body to achieve this.
In the program it was said that in extreme heat and/or high humidity conditions, the wrong thing to do is to get rid off clothing. Even though the automatic thing to do is to get rid of it to get the cooling factor.
Protective clothing (in our case ATTGAT) will slow down the dehydration process.
Maybe a point to ponder on extended trips and maybe emergency situations. Getting lost/stuck with little water.
Might have it wrong here and there.
Any members here which can confirm/expand on this?
