If you are somewhere really hot but you have unlimited access to cold water, can you still die of heat exhaustion?

It would depend on:

* How much sleep you are able to get
* If you are able to eat and rest
* That your internal body temperature remains below around 40°C

Since we are warm blooded mammals, our bodies attempt to keep their internal temperature constant. Human life is only possible between around 35°C and 40°C. (I’m talking about core internal body temperature, not atmospheric temperature.)

28°C – muscle failure
30°C – loss of body temp. control
33°C – loss of consciousness
37°C – normal
42°C – central nervous system breakdown
44°C – death*

* by irreversible protein “denaturing”, or “unfolding”; once the shape of protein changes, it ceases to function properly.

Hope this helps!

No, you can drink hot water all day long in the heat and be fine, I did it for a but somewhere in the desert during the start of summer.
Get as much rest as possible and try to stay out of the direct sun.
Where sun screen or cover your body so that you do not burn.
Move slowly and if you are sweating put something on your head to slow it down.

Trust me, I thought I was going to die from heat exhauston several times and I am still here.

actually it helps your body get used to the heat
