Things to remember in very hot weather

So you haven't been here on the Canadian Prairies in winter, either.
Every winter someone will get a vehicle stuck on a country road and
try to walk a mile or two for help, in a 20-knot wind at -20C. They
don't make it.

The hot weather equivalent of -20° C is 60° C, and nobody makes it in
that, either. You can dress to protect yourself against -20° C, but
nothing you might wear can protect you against 60° C.

In very cold water, near freezing, an unprotected human
is unconscious in under 20 minutes and dead shortly after that, if he
doesn't drown first.

But that's just it: You can protect yourself in cold weather. In hot
weather, you can't.

I haven't heard of an unprotected human dying in a half-hour
on the desert at 45C.

Since you say that you're on the Canadian prairies, that doesn't
surprise me. More than fifteen thousand people in Europe died in 2003
in such temperatures.


Unfortunately, you were not one of them.

I'll second that!

The hot weather equivalent of -20? C is 60? C, and nobody makes it in that,
either. You can dress to protect yourself against -20? C, but nothing you
might wear can protect you against 60? C.

This is completely ridiculous. I assume you just took 20C as an average,
then added and subtracted. You can't do that! 60C is higher than the
hottest recorded temperature on the planet. -20C is routine and common in
a great many inhabited locations. They're absolutely not equivalent.

Of course you can. You can wear light clothes, carry shade, and drink lots
of water.

It never ceases to amuse me just how far you will sink for the sake of
argument. You're a smart guy, I know you are from your posting history.
Yet the things you say are completely ridiculous and nonsensical so much
of the time. There has to be some little voice inside you saying "This
makes no sense! You can't say that -20C is equivalent to 60C!" Such a
position does not survive a moment's critical thinking. And yet you will
apparently make a thousand such assertions before you will ever once say,
"You're right, I made a mistake."

Well, if you can't be reasonable or wise, at least you can be hilarious.

Sure I can. Twenty degrees Celsius is not only close to the average
temperature of the planet, it is also roughly the ideal temperature for human
habitation, according to studies I've read. Minus twenty is forty degrees
below that; therefore the hot-weather equivalent would be forty degrees above
that.

60C is higher than the
hottest recorded temperature on the planet. -20C is routine and common in
a great many inhabited locations. They're absolutely not equivalent.

Their incidence is unrelated to their survivability.

The reason that there is more cold weather than hot among human beings is that
it's far easier to survive in cold weather. A species with an ideal
temperature of 0° C would not be able to survive in an environment with a
maximum of 50+ degrees. Because all living species must shed heat, their
ideal "operating temperatures" are skewed towards the high end of planetary
temperatures by evolution. This in itself shows that heat is more dangerous
than cold.

Of course you can. You can wear light clothes, carry shade, and drink lots
of water.

That will not help in extreme heat. The laws of thermodynamics prevent it.
You can survive in extreme cold with insulation alone, by conserving the heat
that your body continuously produces. But you cannot survive in extreme heat
without actively shedding body heat, and beyond a certain temperature, that
cannot be done quickly enough to maintain core temperature, and you die.

Anthony - you are so ****ing stupid you need to boost your IQ by a few
million orders of magnitude just to reach the level of moron.

Never been in a sauna?

This knowledge is required for a private pilot in the USA. I suspect it's

It may be required to pass a test. But pilots aren't tested every day.

Someone who doesn't know this either is
not a pilot, or somehow has beaten the system. In either case he/she should
not be flying.

There are many people with drivers licenses who shouldn't be driving, and yet,
there they are.

there are many who are too incompetent to be trusted, and yet here you
are.

No. The extreme heat of a sauna is dangerous and uncomfortable, and I don't
see any advantage to them.

What a remarkable sheltered and pathetic life you must lead. A life of
nots -- not flying, not hot, not cold, without friends, all wrapped up
in an opinionated judgmental persona. You offer us a benchmark to
remind us to be joyful for our lives.

That's quite a complex conclusion to draw from a simple dislike of saunas.
