Yep. William Hill odds for Snow on Christmas Day, anyone?

Hey, the guy was melting already how much worse can it get! Out of
interest, would these 'nasty problems' be any worse than being
overheated in the first place?

Oh I don't know, INAMP. Going from overheated immediately to overcooled
is a problem, it puts strain on the body's blood pumping system - which
may be something not good if other cardiac problems exist. Running your
cold water over your wrists may be a temporary solution that might make
feel good, but placing a heat pump there (or in your hat etc...) would
be a signal for the brain to start things compensating.

Doing it slowly is not a problem, and googling "heart attack" and "air
conditioning" reveals a clear benefit in installing these systems.

I wouldn't have thought (but will
quickly stand corrected) that there would be that much cooling in the
above (say compared with a sauna then a plunge pool). The cooling
effect uses the 'latent heat of vapourisation' (isn't it) from the
surface and the 'cold' would then have to conduct through the (wet)
fabric to the skin (not sure how efficient that would be). At the same
time the body would be heating the wet shirt up?

Yup. Laws of Physics helping out Laws of Nature by making sure wet
T-shirt owners don't over do it!

Isn't instant human combustion to do with high levels of phosphor or
summmat?

I went off to look at some web references. Found the topic so gruesome
that I apologise for raising it up in jest(!)
