Gentlefolk,
You need to be careful with rehydration - especially
in tropical climes.
Your body loses salt as well as water when you sweat
and if you replace only with pure water, eventually
you will develop 'water intoxication'.
This is, actually, not easy to achieve in a few hours
but can be done - typically in hospital, after surgery
- if only dextrose is given intravenously (because
the victim cannot take anything by mouth) rather than
dextrose/saline or just saline solution.
It is, however, quite possible in the flying context,
especially with prior sweating/pure water replacement
in a hot environment.
A reasonably early symptom is cramp (underground miners
used to get it by sweating a lot & replenishing only
with pure water - so-called 'miners' cramp').
Take to extremes, this syndrome can result in convulsions
& death - with mental impairment in between.
I suggest simple, diluted, fruit squashes.
These have ample salt - and occasional use will not
lead to galloping hypertension or any other, modern,
crime against humanity - unless, of course, you are
severely predisposed.
Opening pressurised bottles & cans at altitude is an
amusing hobby - if you like the contents splattered
all over yourself, your instruments and the canopy.
Coca Cola is particularly obnoxious !
Have been there, done it & wear the T-shirt !!
Cheers,
